High Intensity Strength Training For Better Body Composition

February 11th, 2008|Sports Coaching, Sports Exercise Science, Sports Studies and Sports Psychology|

During the past several years we have learned a lot about the effects
of strength training and body composition. For example, a carefully controlled
study at Tufts University showed significant changes in body composition
from a basic program of strength exercise (Campbell et al. 1994).

The subjects added three pounds of lean weight, lost four pounds
of fat weight, increased their resting metabolic rate by seven percent and
increased their daily energy requirements by 15 percent after 12 weeks of
strength training.

Research with over 1100 previously sedentary adults revealed similar
body composition improvements from eight weeks of standard strength training
(Westcott and Guy 1996). The program participants increased their lean weight
by 2.4 pounds and decreased their fat weight by 4.6 pounds.

Of course, unfit individuals tend to improve their body composition
at faster rates than people who are presently doing strength exercise. Many
people want to know if strength training can further enhance body composition
in well-conditioned exercisers.

Previous studies have demonstrated that various high-intensity training
techniques are more effective than standard training protocols for increasing
muscle strength in both beginning and advanced participants (Westcott 1996,
1997a, 1997b; Westcott and La Rosa Loud 1997). As shown in Figures 1 and
2, slow training produced greater strength gains than standard training for
both beginning and advanced trainees. As illustrated in Figures 3 and 4,
breakdown training resulted in greater strength gains than standard training
for both beginning and advanced exercisers. Likewise, assisted training generated
greater strength gains than standard training for both beginning and advanced
subjects (see Figures 5 and 6).

We have recently examined the effects of combined high-intensity
training techniques on body composition changes in well-conditioned participants.
The six-week advanced exercise program included slow training, breakdown
training, assisted training, and pre-exhaustion training. The 48 subjects
added 2.5 pounds of lean weight and lost 3.3 pounds of fat weight as a result
of their training efforts, which represented more improvement than we expected
from regular strength exercisers.

We have been pleased with our participants’ positive response to
the combined approach of high-intensity strength training techniques. Our
standard exercise protocol is outlined in Table I.

We observed that many program participants selected the pre-exhaustion
technique for their sixth week of high intensity training. Although we do
not have data that show this training method to be better than the others,
there may be some benefit in performing more pre-exhaustion sessions.
Psychologically, changing exercises at the point of muscle fatigue may be
more appealing than performing more repetitions of the same movement pattern
with less weight or with manual resistance. Physiologically, performing two
different exercises for the target muscle group recruits more muscle fibers
which may enhance the training stimulus. In addition to more exercises,
pre-exhaustion programs require more training time and may therefore be the
best high-intensity technique for burning calories.

As many of our intermediate level strength trainees want to improve
their body composition, we presently provide high-intensity training programs
with more emphasis on pre-exhaustion techniques (Table II). The results are
encouraging, but we try to be cautious about overtraining. Our members seem
to respond well to six weeks of high-intensity training followed by six weeks
of standard training to maintain their new level of strength and
fitness.

Although we have not previously provided nutritional counseling to
our high-intensity training participants, this would undoubtedly be beneficial
for clients who want to lose fat as well as build muscle. A combination of
individualized high-intensity strength exercise and sound dietary guidelines
should produce significant improvements in body composition.

International Youth Sport Tour Benefits

February 11th, 2008|Sports Facilities, Sports Management, Sports Studies and Sports Psychology|

International youth sport tours are travel programs that provide youth teams with the opportunity to travel to and compete against sport teams from other countries. In addition to competing, the team members and their families and/or friends are able to tour the countries, cities and areas where the competitions are held. These team sport competitions, therefore, afford experiences and benefits that are difficult to duplicate without international travel taking place. This paper will look at the benefits derived by team members who participated in European sport tours organized by this writer. The information for this paper has been obtained from written evaluations completed by past sport travel participants (team members, families and friends who completed the tour).

Adventure is one obvious result of international travel. Many youth sport team members have never flown before; most have never been to a foreign country where English is not the primary language; and almost all express a fear or concern about the possible problems that could and sometimes do develop. Before, during and after the trip, the sense of adventure and accomplishment exists. For some, this may be the greatest adventure of their lifetime, and an experience that will be remembered and talked about forever.

The learning that takes place during the international travel experience is another very apparent positive effect of international sport competitions. Hearing a new language, being immersed in another culture, shopping with foreign money in a store where English is not the primary language, seeing and visiting attractions that are the highlights of courses taken; visiting museums and castles; going to local festivals and concerts and living as though a resident of a foreign country provides experiences that cannot be duplicated by reading or in the classroom. International youth sport competitions afford learning experiences in geography, foreign language, sociology, math (money exchanging, metric conversions, etc.), history, art and music.

Friendships, sometimes lifelong, develop during these travel programs. Meeting with opponents and their families during and after the competitions (socials with opponents and their families are offered) allow participants to start interactions that often result in written correspondence and exchange visits. Competition often results in the reducing of psychological, sociological, cultural and language barriers that impede interaction with others. If you can play against someone on the court, you can almost always socialize with him/her off the court.

Improved eating habits also sometimes result from foreign travel. With breakfasts, lunches and dinners containing foods not commonly eaten in the United States, the boys and girls on these sport excursions often find themselves trying and enjoying soups, salads, cheeses, pastas, meats, vegetables, breads and desserts they have never previously tasted. Although, a visit to a McDonald’s during the tours is always a welcome break, follow-up evaluations indicate that a number of past participants will not so readily turn away from meal offerings that would not have been considered prior to the trip.

Communication and listening skills are often enhanced during foreign travel. How does one communicate without knowing the language? Most participants quickly gather this knowledge. Learning key words and/or some basic sign language becomes a necessity. Listening and trying to understand a new friend who has a difficult time speaking English takes patience and attention. Boys and girls who are often considered shy may become more extroverted as a result of this foreign travel experience.

Increased self-reliance and self-confidence often result as by-products of these international sport competition experiences. After lengthy instructions, Team members are given the opportunity to tour with friends, but without parents, the old sections of such cities as Venice, Innsbruck, Vienna, Florence, Budapest, Interlaken and Verona. Getting along on your own in a foreign land, even for just a few hours, provides a very satisfying feeling of accomplishment. They are now world travelers.

Playing against different styles of play in different facilities can enhance the individual skill levels of the competition tour members. Youth hockey competitions in Italy provide an excellent example. Unlike U.S. hockey, Italian youth hockey rules frown on player contact, thus stressing the importance of skating and stick handling skills. In addition, youth hockey games are played on the larger Olympic size ice surface. Competing with Italian teams is a great way to improve skating and stick handling skills.

Another and the final benefit to be mentioned in this paper is the prestige of having competed in Europe that results on the participant’s return to the United States. Families, friends and competitors pay notice of this accomplishment, and the fact that the participant is now considered special, because of having participated in international sports play, and having traveled abroad. The participant, of course, will have trophies and mementos of this experience, that when displayed will result in a long-term recognition.

As indicated, the benefits to boys and girls from the United States who compete in sports competitions in foreign countries are numerous. Participating in an adventurous experience, learning in a variety of disciplines, friendship development, improved eating habits, enhanced communication and listening skills, increased self-reliance, skill improvement, and enhanced prestige are included among the benefits. Although, the cost for participating on these international travel programs may be viewed high by some, the lifetime benefits that are gained could result in these youth competitions being considered as bargains.

Sports Medicine for Youth Soccer

February 11th, 2008|Sports Coaching, Sports Exercise Science, Sports Management, Sports Studies and Sports Psychology|

Training for Optimal Performance

Soccer is a major sport for young athletes in the United States, and is also rapidly becoming a major sport for males and females for all ages. Because young athletes go through puberty at different times, they vary a great deal among each other in size and maturity. These differences pose a challenge to the athletes and their coaches. The primary characteristics of a young athlete are: motivation; physical fitness (i.e. muscle strength, power, endurance, flexibility, proper body composition, and cardiac respiratory endurance); discipline, coachability; skills; ability to be a part of a team; ability to think under stress; and good spatial orientation.

The practice sessions for soccer should seek to achieve: physical conditioning, repetitive training, proper intensity of training, flexibility, and awareness that the achievement of proper endurance for the soccer athlete requires 4-6 months of training. Also, the coach should be aware that extreme and severe high intensity and high frequency training causes damage to muscle tissues and is counterproductive to the goals of the athlete. The pre-game meals should primarily be composed of carbohydrates, and balanced meals should be eaten prior to game days. Water consumption (hydration and rehydration) should be strongly encouraged with water breaks built into the training schedule and water available upon demand.(2)

Physiological and Chronological Age

Any middle school teacher can tell you that adolescent teenagers are difficult to handle and that they vary a great deal in size, height and maturity. This is because teenagers, in addition to possessing the normal genetic inheritance of size from their parents, are also in a very fast growth period (puberty). The growth spurt on the average is around 12 years of age for girls and 14 years of age for boys. Young athletes are experiencing a turmoil period which affects them both physiologically and hormonally. Therefore, young athletes come to soccer with these inherent and at times large differences in size, shape, height, and skill level. Because of these differences, it is very difficult to mold a team at this age group into a skilled unit.

Characteristics of a Soccer Player

All of the following player characteristics need not be present before the individual plays soccer. However, the individual should either show aptitude or at least a willingness to acquire these characteristics.

 

1. Motivation

The soccer player should be interested and motivated to play the game of soccer (i.e. kicking a ball, running, passing a ball, etc.). In other words, the player is receiving an enjoyment out of performing these tasks especially when it is performed spontaneously and without adults forcing them to do so.

2. Physical Fitness

The term physical fitness connotes different meaning for different activities. In the

context of soccer, it is the ability to play soccer for 60-90 minutes without fatigue, exhaustion, or other malsymptoms of a sedentary person. The player should have the following physical fitness characteristics to play soccer:

a. muscle strength and power
b. endurance
c. flexibility
d. proper body composition
e. cardiac respiratory endurance

3. Discipline

The ability to practice and play the game in a repeated fashion several times a week.

4. Coachability

The ability to take instructions and to try to comply with these instructions.

5. Skills or ability to learn skills

The ability to conduct or learn individual soccer skills with the ball such as kicking, receiving, passing, shooting, control, etc.

6. Ability to play in a team sport

The ability to cooperate with other team members to achieve a difficult task. Also, the player should have the ability to accept less personal recognition for the sake of the team. The player also should be able to associate with others for a long time and sometimes under stressful conditions. Finally, the player should have the ability to enjoy himself with others.

7. Ability to think under stress

Most people are not as logical under stressful conditions as they are normally. However, the well trained soccer player learns what to do under the various game conditions, and also learns to think quickly under stressful conditions.

8. Good Spatial Orientation

The ability to think and visualize in three dimensions and to be relevant to the soccer field is difficult for very young players. The player should be able to learn to adapt to the spatial orientation within the field and re-position himself/herself relevant to the ball, teammates and the opposing team members.

 

Practice Sessions

The purpose of this article is not to suggest specific exercises. There are other sources for the numerous soccer practice sessions. However, we will give a general outline that all soccer practice sessions should fall within. In this manner, each coach can use their creativity to make soccer practices more enjoyable and more beneficial to the different needs of the varied groups.

The practice sessions should be designed to make the individual a better soccer player. The best practice for any sport is to play that sport repeatedly in order to develop those muscles, skills, endurance, etc….., for that sport. It is a common occurrence for those who play one sport and then suddenly play another sport to have muscle aches after the first few times of the new sport. This is because they have used a different new set of muscles than they used before. This is called specificity of training. So, the more the soccer player plays soccer, the better he/she will become. This is not to say that the soccer game should not be broken down to small segments so that it can be taught and repeatedly reinforced.

In order to prepare the individual to play soccer, players and coaches should observe the following factors:

 

1. Physical conditioning

Increased ability to sustain both aerobic and anaerobic exercises.

2. Frequency of training

This should be 2-3 times a week for youngsters and 3-4 times a week for adults.

3. Warm-up

Static stretching should last 10-30 seconds and be repeated 3-5 times. Each stretching exercise should include a larger range of motion than the previous one. In addition, after each rigorous practice session, there should be 10 minutes of low to moderate cool-down exercises. Examples of cool-down exercises in soccer are individual skill exercises; jogging lightly, and best of all just walking or dribbling the ball lightly.

4. Time to peak endurance

Quick and severe training for 2-3 weeks prior to a season as is the case in some high schools after sedentary summer, cannot achieve endurance and may be detrimental to the athlete. This is because adaptation of the cardiorespiratory system and muscle enzymes require about six months of training to reach peak endurance capacity. Moreover, it takes 2-4 weeks without training (as may be the case during the summer for high schoolers) to lose most of endurance parameters (see section on endurance for details). Therefore, a well-planned long training period is an essential part of preparing players for the season.

5. Muscle Strength and Power

The use of moderate weight lifting for young athletes to increase strength and power in moderation is an acceptable form of exercise. Weight bearing exercises for children below 13 years of age is not recommended in the standing position where there is a great deal of compression force on the legs. In order to increase muscle strength, the muscle should be challenged by at least 60% of the maximal weight lifted the first time. Furthermore, in subsequent days and weeks, the muscle must be challenged by increasing weights, with high frequency repetition. Remember, an increase in muscle strength is not necessarily associated with a large increase in size of the muscle. Low frequency repetition increases the size of the muscle (body building) rather than increasing the muscle strength. While defenders may be able to use a greater muscle mass and strength, other soccer players need to increase strength more than muscle size in order to keep their agility and speed.

Soccer is a mixture of aerobic and anaerobic sport. Therefore, the training session should combine both modes. Aerobic (like marathon running, jogging, etc…) sessions are usually composed of slow rhythmic exercises. These exercises allow the body to utilize oxygen to burn foodstuff to produce the energy needed. Therefore, the best soccer training sessions should resemble match-like conditions which involve both anaerobic and aerobic exercises. These conditions consist of the player performing, for example, the following tasks:

 

(a) Aerobic exercises such as continuous jogging to re-position to a new ball position lasting 1-5 minutes. Repetition of this action 10-50 times per game.

(b) Anaerobic exercises such as sprinting — lasting from a second to 1 min. Repetition of this action 10-50 times per game.

(c) Midfielders do most of the jogging and sprinting throughout the game since they must perform offensive and defensive tasks.

(d) Defenders tend to do mostly jogging and less sprinting.

(e) Offensive players do more sprinting than jogging.

 

The details of the sessions should be left to the creativity of the coach to combine multiple game-drills that benefit the most for a given player and team.

Usually young players play more than one position (i.e. offensive versus defensive position). However, as the young players pass puberty, they become more specialized in a given general position. Therefore, each position may require slightly different emphasis. For example:

 

(a) Offensive players do mostly sprinting than jogging and therefore would require more anaerobic process adaptation.

(b) Defensive players tend to do mostly jogging and less sprinting and therefore would require more aerobic process adaptation.

(c) Midfielders tend to do both sprinting and jogging throughout the game since they must perform both offensive and defensive tasks. Therefore, midfielders would require an intensive training to adapt to both aerobic and anaerobic processes.(1)

 

Interval Training

The soccer player can benefit from interval training. Interval training consist of work bouts with rest intervals of ratio varying from 1:3 to 1:1 (work/rest) depending on the need and the physical fitness of the individual. The work period can lasts a few seconds up to several minutes. The whole cycle can be repeated 5-20 times. A short high intensity (sprinting) work bout lasting greater than 15 seconds can improve the anaerobic system with rest period of 30 seconds. Interval training to improve the aerobic system could consist of ratio’s of 1:1 or 1:1:5. The exercise period could last 60-90 seconds in order to force oxygen consumption followed with a recovery period varying from 60 seconds up to 135 seconds.(2)

Circuit Training

Circuit training attempts to use economically time of exercise to improve strength, power and cardiorespiratory system. Work sessions should combine resistance, speed and rest. For example, working periods can vary from 30-60 seconds with similar rest periods. The number of different stations could be as high as 15 stations of differing exercises.(2)

Water and Electrolyte Balance

Water is the most important and critical nutrient to the survival and well being of a person. One can survive without intake of other nutrients for days, weeks, and even months but one cannot survive without water for more than a few days. In a 70 Kg person, the water content is about 40 liters (i.e. 60% of body weight). Most of the water (25 liters) is inside cells of the body and about 15 liters lie outside the cells. The blood volume is about 5 liters and the maintenance of this volume is critical to the survival of the person. For example, daily fluid intake can vary from 1-7 liters, while the blood volume must remain constant. Excess fluid intake can easily be regulated; however, a problem. arises when fluid intake is below one liter per day and blood volume starts to become lower than 5 liters (for example about volume of 4 liters and below can cause death). Under sedentary conditions skin and kidney (i.e. urine output) are the most important regulators of body water. Under the conditions of hot weather and exercises (despite fluid intake in many cases, the skin (sweating) becomes the only important regulator of body water as well as the body temperature. The daily loss of water in a heavy, prolonged exercise (3 hours marathon) can increase from 0.1 to 5 liters.(6)

Sweating is absolutely necessary in order to maintain constant body temperature. The sweat rate usually corresponds to increases in energy expenditure by the athlete. Trained athletes have a more sensitive sweating system than non-athletes due to adaptation by the repetitive exercises. Of the 5 liters of H2O, a marathon runner’s losses (despite fluid intake in many cases) represent 12% of body water and 8% of body weight. Anything above 2% weight loss due to exercise induces severe demands on the thermoregulatory and cardiovascular systems.

All of the energy expenditure during exercise ends up as heat. Therefore, body temperature will rise rapidly during exercise if cooling due to sweating is not functioning. The prolonged increase in body temperature will eventually cause serious damage to the thermoregulatory system, which can result in serious damage to the brain — the most sensitive organ. Thirst, unfortunately, is not a reliable indicator during exercise (i.e. under any stressful conditions). Therefore, athletes should drink water not just to quench their thirst, but as part of their exercise regime. Figures 3 and 4 represent a hypothetical daily water output and water intake for persons who are: sedentary, a marathon running for 3 hours, or soccer players (90-100 minutes). The numbers are rough estimates, and for illustration purpose only. The most scientific way to determine how much water intake ought to be is to weigh the player before and during the game. The loss of weight due to water loss should be adjusted by drinking the same amount of water. Remember, it is better to drink more than less water.

Children utilize a greater metabolic energy and thus produce more heat than adults to perform the same task. Fortunately, children dissipate heat better than adults due to a larger surface area to mass ratio than adults. However, when ambient temperature is hot and humid, the dissipation of heat is inhibited and thus children maybe at a greater risk than adults during exercise.

Electrolytes such as Na+, K+, Cl-, Ca2 and Mg2+ are the most important ions and their amount in the cell and the blood is critical in maintaining normal body function. As we sweat more during exercise, the amount of these ions in the sweat is less than that of the blood. In other words, the body is losing more water than ions. Under heavy exercise conditions, the body loses about 5-7 grams sodium chloride. However, there is a minimal loss of K+ and Mg2+. Under conditions of continued exercise (up to 80-90 minutes) there is a need to replenish water continuously, but not salt. If there is heavy exercise beyond the 80-90 minutes, salt replenishment is appropriate. The use of salt tablets during the early phase of exercise (in most cases of soccer) is detrimental to the body. The body fluid has a higher salt concentration after exercise than before; therefore, the body needs pure water to bring the blood composition back to normal levels.(6)(2)

Heat Related Illnesses

Heat Cramps

They are similar to other muscle cramps, which may be due to: sudden blows; over exercise; lack of blood supply, etc.

 

Cause: Reduced blood flow to the muscle due to: loss of water, prolonged loss of minerals, etc.

Symptoms: Spasmodic tonic contraction of a given muscle.

Onset: Gradual or sudden.

Danger: None if treated. Heat cramps could lead to termination of that particular exercise for a few days.

Prevention: Proper physical fitness, proper warm-ups and stretching exercises prior to the activity and temporary termination of activity.

Treatment: Termination of activity. Stretching, rest and ice treatment necessary.

 

Heat Exhaustion

 

Cause: Loss of water.

Symptoms: Tiredness, weakness, malaise, and progressively weaker.

Onset: Gradual and over several days.

Danger: The player may go into shock because of reduced blood volume This rarely happens, however, as it is not an emergency condition.

Prevention: Proper physical fitness and proper hydration before and during the exercise and termination of activity.

Treatment: Cooling, drink water, and later drinking large amounts of mineral rich fluid such as fruit and vegetable juices.

 

Heat Stroke

Brain cells in the hypothalamus maintain body temperature close to 98.6oF. These cells respond to the blood temperature that passes through them. The cells regulate the skin by sending signals to release skin vasodilator in order to increase sweating. When rectal temperatures reach 41oC – 43oC, unconsciousness may develop; if that happens, the mortality rate ranges from 50-70%. Heat stroke is the second cause of death among athletes.

 

Cause: Loss of water and sudden uncontrolled rise in body temperature due to the failure of the thermoregulatory center in the brain.

Symptoms: It is a Medical Emergency. May lead to death or irreversible damage. Person shows behavioral or mental status changes during heat stress. These symptoms include: sense of impending doom, headache, dizziness, confusion and weakness. Symptoms that could lead to heat stroke are:

 

a. high temperature and high humidity
b. high rectal temperature
c. hot dry skin
d. cardiorespiratory and central nervous system disturbances
e. clouded consciousness and finally collapse

 

Onset: Sudden

Danger: Brain damage and death is imminent if not treated quickly.

Prevention: Proper physical fitness and proper hydration before and during the exercise and termination of activity.

Treatment

 

1. Call for an ambulance.
2. Remove clothes and cool with ice and cold water on the body.
3. Monitor vital signs. (i.e. breathing, heart beat, pupil size).
4. Massage extremities to promote cooling.
5. Once the body temperature cools and the person is quite alert, remove from cold environment to prevent hypothermia.(3)

 

In the hospital they may perform the following:

 

1. Administer I.V. fluid (1400 ml for first hour).
2. Monitor urinary output – Mannitol may be given to promote urination.
3. Digitalis may be considered for heart failure.
4. Isoproterenol administration to increase cardia output (if needed).
5. Oxygen may be given.
6. Other procedures as necessary may be used.
7. Continue to monitor kidney and brain functions.

 

Adaptation of Endurance Training

Endurance training connotes a process of adaptive changes to achieve the strength, power and cardiorespiratory capacity to complete the specific physical task. Endurance training requires several months of rhythmic and continued exercise that results in an increase in the body’s number of capillaries, maximal oxygen uptake, stroke volume, and enzymes. Moreover, endurance training increases the sectional size of slow type fibers and there is an actual conversion of fast type fibers (Type 11B.) to slow (Type 11A.). The Type 11B. fibers are the fast fibers, and are capable of lasting longer than the type 11A. fibers. Therefore, there are major underlying biochemical changes in the various organs and cells involved in the physical activity that provides the needed energy, strength and power to carry out the task. Soccer requires a combination of slow and fast fibers because soccer playing is a combination of quick actions lasting less than 1-2 minutes and a prolonged activities which can last 5-10 minutes.

Athletic physical conditioning has become a very serious and scientific endeavor. In the past 20 years, there has been an increase in our understanding of the physiology and biochemistry of exercise. There has also been an increase in interest in the mechanism of how exercise induces physiological and biochemical adaptation at the cellular and organismic level and how this accounts for the improved performance of athletes in a given sport.(1)

Endurance in sports means the ability of the person to perform a specific prolonged exercise or work to achieve a reasonable task without adverse reactions such as fatigue, exhaustion, and injury. Endurance can mean different things for different tasks (i.e. sport activity), as each task may involved unique muscle groups and skill levels. Therefore, there are several components of endurance that develop differentially during endurance repetitive training for the specific sport. The components of endurance are: muscle strength and power, the cardiovasculatory system, and the respiratory system. The cardio-respiratory endurance is needed with varying intensities in all sports. However, strength and power can vary in magnitude from muscle to muscle. Therefore, local endurance is quite important for a given sport. During endurance training of repetitive exercise for several months, the muscles adapt to generate force and to maintain a supply of energy. The key factor in endurance training is the exertion of physical stress with certain frequency and for lengths of time. This chronic muscular activity stimulates growth of the muscle as well as the development of endurance in terms of oxygen delivery, energy production, and permanent metabolic and structural changes. Therefore, endurance training in this context is a low-level, prolonged-intensity aerobic training exercise where the system can utilize oxygen as the initial trigger of energy source. The first general aspect of endurance adaptation is the adaptation of the cardiovascular/respiratory system to accommodate the increased frequent demand for oxygen uptake and delivery.

Cardiovascular – Respiratory Adaptation

Rhythmic and continued exercise requires a greater use of oxygen at the muscle site. Therefore, the routes of uptake and transport of oxygen from the air to muscle tissues must adapt to the increased rate of delivery and extraction. A measurement of cardiorespiratory endurance is the VO2 max. VO2 max is the maximal oxygen uptake during the maximal exercise, and it differs from person to person. In order to compare exercise-related data from person to person, the data is expressed relative to a specific level of intensity of exercise and represented as expressed as a percent of VO2 max. To illustrate its importance, endurance training can change the VO2 max by as much as 20%. This is the first indication that true structural and biochemical changes must occur in order to metabolize the increased oxygen uptake. The first apparent result of an exercise is the immediate increase in heart rate. The resting rate is 80 beats per minute; however, during exercise the heart rate can go as high as 190 beats per minutes. After several months of endurance training, heart rates can go as low as 40 beats per min. This reflects several factors of adaptation to exercise among them being the autonomic nervous system. However, the one aspect related directly to the heart rate is the fact that despite the lowered heart rate, the heart provides a greater cardiac output because the stroke column increases by as much as 80%. In a highly trained athlete, the refilling is more complete. More importantly, the left ventricle strength and power is dramatically increased. The left ventricle undergoes hypertrophy with endurance training, which means the actual heart muscle mass and volume are increased. Heart size is greater in endurance trained athletes by as much as 25%, as compared to a sedentary person. Moreover, the contraction of contractile proteins are increased and the composition of the protein changed. Also, oxygen delivery of the blood supply to the heart is improved because the number and size of capillaries per cross-sensational areas of muscle increases by as much 50% due to endurance training. Endurance training also improves (by as much as 80%) the muscle content of myoglobin. Myoglobin carries oxygen within the muscle tissue. These dramatic biochemical adaptations in the oxygen delivery system parallels those of the heart and thus complements the entire scope of the biochemical adaptation for a better performance by the trained athlete.(2)

Blood Volume and Composition

There are three major changes in the blood due to endurance training: (1) increased blood volume; (2) increased hematocrit (i.e. increase in the total number of red blood cells (RBC); and (3) decrease in viscosity. The increased blood volume is as high as 20%. However, the increase in RBC is less pronounced and as a consequence the viscosity of the blood decreases. The increase in blood volume is the key important factor for an endurance trained athlete. The increased blood volume enhances O2 delivery as well as enhancing microcirculation. The increase in microcirculation is even more pronounced due to the blood’s reduced viscosity. A trained athlete also has another advantage in greater capacity to clear lactate from the muscle and utilizing lactate as an energy substrate. Thus, the level of blood lactate in a trained athlete is lower than in a sedentary person. This phenomenon is referred to as a lactate shift. A trained athlete therefore has a greater endurance with less fatigue and cramps due to decreased levels of blood lactate.

Common Injuries Encountered in the Sport of Soccer

The physiological principles of tissue damage and tissue healing are essentially the same for all sports. What makes each sport somewhat unique in terms of the injuries encountered is the specific sport activities which lead to specific mechanisms of injury. The soccer skills involved with passing and dribbling, kicking, ball control, heading, tackling and goal keeping all, when combined with the principles of force, gravity, ground contact, and torque, can lead to injuries.

Unfortunately and wrongly, our youngest athletes (such as youth soccer players) receive the least sports medicine coverage. Therefore, injury recognition and evaluation becomes the premise of the coach or parent who may have little or no preparation for the task.

In an attempt to simplify the evaluation procedures, the most basic acronym, HOPS, should be employed. HOPS stands for history, observation, palpation and strength/sensation. This primitive evaluation system may be utilized with any type of injury.

A good preparticipation physical examination is mandatory. This provides the benchmark from which deviations from the norm may be measured. A good preparticipation physical should minimally include a medical history, height and weight check, visual acuity check or screen, orthopedic or joint evaluation and visceral examination. Physicians specializing in sports medicine are the best sources for these physical exams.

Observation begins the first time one sees the injured athlete. Is he/she conscious, does the athlete walk with an antalgic gait, does the athlete hold any body part as a protective manner, and is the athlete visibly exhibiting pain? These are all important observational factors. Also, if one is dealing with an extremity injury, the evaluator should visibly compare that limb to the contralateral or uninjured limb.

Palpation involves touching and moving the injured body part. If pain is diffuse, palpation may be of limited value. However, if the pain is specific or point tender, then active, passive and resitive motion will assist the evaluator in localizing the injury site or injured structure.

Strength/sensation is the final aspect of the field evaluation. Again, if dealing with an extremity injury, one has the luxury of being able to compare strength and sensation of the injured limb to that of the uninjured.

Common injuries encountered in the sport of soccer include:

  •  

    Sprains: A sprain represents damage to a ligament. Common sprain sites include the ankle, knee and wrist.

  •  

    Strains: A strain represents damage to a musculotendinous unit. Common strain sites encountered in soccer include the gastrocnemius, quadriceps, hamstring, low back and shoulder.

  •  

    Fractures: Common fracture sites include the fingers, tibia, fibula, radius and ulna. These fractures are usually resultant from falls. The only method of positive fracture diagnosis is X-ray.

  •  

    Dislocations: Dislocation sites commonly encountered may include fingers, should and elbow. The most common mechanism of injury resulting in a dislocation is the fall on the outstretched hand or arm.

  •  

    Contusions: Contusions are resultant from contact with the ball, with other players, or with the ground.

  •  

    Concussions

 

When does an injury need to be referred to a physician? Although this is a difficult question to answer, the following guidelines will assist the layman in making the decision:

 

1. Suspicions of a fracture
2. Suspicions of a concussion
3. An injury in which the pain cannot be controlled with conservative measures
4. A laceration that may require sutures
5. Any suspicion of internal injury

 

Additionally, any time the layman is unsure of his/her evaluation, the athlete should be referred to a physician.

Conservative Care of Acute Injuries

The acronym PRICE represents a form of conservation care for acute injuries.

“P” stands for protection. An ankle injury can be protected by placing the athlete on crutches non-weight bearing.

“R” stands for rest. Rest means not using the injury body part and allowing it to heal properly.

“I” stands for ice. Ice or cold is utilized in cryotherapy. The use of ice results in a greater chance of tissue survival, reduces degradation of healthy tissue, induces vasoconstriction which prevents further swelling and loss of range of motion and enhances early mobilization. Ice also acts as a topical anesthetic.

“C” stands for compression. Specific compression when applied to an extremity injury may prevent swelling and the accompanying loss of range of motion.

“E” stands for elevation. By elevating an extremity injury, once reduces effusion and dependent bleeding. Again, this reduces swelling and loss of range of motion, both of which tend to protract injury recovery time.

Remember, the whole idea behind the science of sports medicine is to provide the best possible environment for healing to occur.

Summary

Youth and age group soccer can be an extremely positive experiences for the young athlete. Skill development, coordination, socialization skills, and cooperation are all positive results of a healthy youth and age group soccer program.

In order to assure a healthy program, one must insist that sports medicine considerations such as preparticipation physical exams, proper conditioning, conservative injury care and warm- up and cool down periods are observed as well as adequate hydration and rehydration.

The Effects of Video and Cognitive Imagery on Throwing Performance of Baseball Pitchers: A Single Subject Design

January 7th, 2008|Sports Coaching, Sports Exercise Science, Sports Studies and Sports Psychology|

ABSTRACT
The purpose of this study was to examine the effects of a three-week imagery and video imagery intervention program on the throwing accuracy of individual baseball pitchers. A secondary purpose of this study was to investigate whether differences in accuracy response characterize both low- and high-ability imagers. A sample of pitchers (n=30) were asked to take the Movement Imagery Questionnaire–Revised; study participants were randomly selected from the highest and lowest 20% of the group. The participants were obtained from high school and college teams within southeastern Georgia (n= 6). Following the first week of baseline measurements, 2 high-ability and 2 low-ability imagers took part in a three-week video imagery and imagery intervention program. One participant from each group together constituted a control group, which was asked only to try their best when throwing for the study’s accuracy measurements. Results showed that 2 participants demonstrated an increase in performance, while all participants expressed a desire to continue to use imagery for its various effects. Suggestions for future research and further insight are discussed.

INTRODUCTION
Imagery has been shown to be very effective for improving accuracy in sport. Thomas and Fogarty (1997) found that imagery combined with positive self-talk improved not only putting performance, but psychological factors as well. Woolfork et al. (2005) found that positive imagery participants, in comparison to negative imagery training and control group participants, experienced significant increases in putting performance. Moreover, imagery has been shown to positively enhance free-throw shooting among collegiate basketball players. Kearns and Crossman (1992), Shambrook and Bull (1996), Templin and Vernacchia (1993, 1995),Stewart (1997), and Carboni, Burke, Joyner, Hardy, and Blom (2000) have determined imagery to be to some degree effective for most individuals at enhancing free-throw performance.

Much of the research cited above utilized a single subject design. This type of design has proved important in applied sport psychology, demonstrating improvement in individual cases that might be overlooked by traditional group analysis (Shambrook & Bull, 1996). For instance, when a multiple baseline design is used, a conclusion could be drawn that any effects were due to the specific intervention (Bryan, 1987, p. 286). The single subject design, in contrast, allows for individual analysis of the imagery implementation and a way to tailor the intervention to the individual (Stewart, 1997).

Visualization theories have not always been applied to sport performance; they began in the field of cognitive and spatial awareness research. Bess (1909) was among the first researchers of the topic and is credited with developing the measuring system for visualization. The Bess Scale addresses differences in individual imagery ability, drawing on cognitive theory of imagery and tied closely to the understanding of the term kinesthetic imagery(Schiffman, 1995).

A pitcher may be asked to imagine the ball in hand before a throw, to feel the laces and texture on the palm, maybe even to brush the dirt off, as if the ball was just grabbed from the ground. Bess notes that the image should be as clear and detailed as possible, and his Bess Scale measures the vividness of the visualizations practiced with seven classifications of vagueness and vividness. However, Wilson & Barber (1981) found that individuals can vary greatly in their ability to visualize, even when their Bess Scale scores are alike. Moreover, Stoksahl and Ascough (1998) also found that some athletes were very detailed in their imaging, while others were very vague; they concluded that the less vivid images may not be as effective for enhancing performance. Therefore, athletes with lower imagery ability may not reap full performance-enhancement benefits from imagery training. Such findings provide one more reason to investigate the effects of video imagery: Individuals who lack vivid imaging skills may find that a video re-enactment of the task allows them to see the desired performance very clearly, aiding mental preparation for an actual event or task demonstration.

Little research appears in the literature which has examined the effects on performance of internal video imagery, or video depicting an athlete’s internal perspective during performance. However, at least some research has integrated videotape modeling with imagery training. Hall and Erffmmeyer (1983) investigated female high school basketball players who were assigned to a video modeling/imagery group and a relaxation/imagery group. Results can only be attributed to a combination of psychological skills, as they were compounded within the study, but it was concluded that the video modeling/imagery group demonstrated better performance in foul shooting, compared to the relaxation/imagery group. Little research seems to exist exploring internal video imagery in other sports contexts, specifically baseball and, more specifically, pitching accuracy.

While general research on imagery is vast, this study seeks to investigate the effects of cognitive imagery and video imagery on one phenomenon: the throwing performance of baseball pitchers. A secondary purpose of this study is to see whether low-ability imagery and high-ability imagery are associated with distinct performance responses following video and cognitive imagery interventions.

METHOD
Participants
The study participants were 6 baseball pitchers from southeastern Georgia. They were selected from the region’s high schools and colleges. Four males, 2 current college athletes and 2 current high school athletes, took part in the study. The participants’ mean age was 19.8 years, with ages ranging from 16 to 22 years. Only athletes currently on pitching staffs of high school or college baseball teams were utilized. All participants had been baseball athletes for at least the previous 2 years, at either the high school or college level. All were asked to return a signed consent form before participating in the study; participants under 18 years of age were asked to return a parental consent form before participating. The consent form assured participants of confidentiality, briefed them on the study’s purpose, and listed the risks and benefits of participation. Contact was made with each institution, informing participants, parents, and coaches that athletes’ participation was completely voluntary.

Apparatus
A Samsung Sports Camcorder SC-X205L/X210L was used to record all accuracy-measurement sessions, in order to ensure that accurate points were recorded for each pitch. At no time, however, was the pitcher himself captured in these recordings. The Samsung Camcorder SC-X205L/X210L external helmet camera module, used to capture recordings of an accurate pitch from the internal perspective of the pitcher, was used in the video imagery interventions.

Instrumentation
Throwing performance was measured with an Easton© 9-square Strike Zone Target, which was placed on the plate in the visitors bullpen at Georgia Southern University, emulating an actual game. Each section of the target was assigned a point value, ranging from 1 to 10; 10 was the value for the center box, with lower values designated for squares nearer the edges of the target. Point values between the ranges of the surrounding boxes values were assigned to the dividing lines themselves. Each pitching accuracy measurement session was videotaped, allowing the researchers to review each pitch at leisure, ensuring the correct assignment of points; however, only the target and the end result of the pitch were captured on videotape during measurement sessions.

Prior to the study, an imagery ability test was given to a group of 30 high school and college baseball pitchers, to identify athletes with high- and low-ability imagery skills who might become part of the study sample. The Movement Imagery Questionnaire- Revised (MIQ-R) was used to measure the athletes’ imagery ability (see Appendix A). Hall and Martin (1997) developed the MIQ-R, a revision of Hall and Pongrac’s Movement Imagery Questionnaire, or MIQ (1983), in order to assess individuals’ capacity to generate visual imagery and also kinesthetic (or movement) imagery. The present researchers have determined the MIQ- R to be a valid and reliable revision of the original instrument: Earlier work has established significant correlations for the MIQ-R’s visual and kinesthetic scales. For the MIQ, Hall, Pongrac, and Buckholz (1985) obtained a test–retest co-efficiency score of .83; in terms of internal consistencies, a score of .89 was obtained for the visual scale and a score of .88 was obtained for the kinesthetic scale (Atienza et al., 1994).

A Post Study Imagery Questionnaire was distributed to the present study’s participants at the completion of the investigation. This questionnaire sought feedback from each pitcher as to prior experience with imagery, present attitude toward imagery, and likelihood of future imagery use. Moreover, it asked the athletes to think about effects of imagery occurring in dimensions other than performance. The questionnaire asked these questions, specifically: Did you at any time use imagery outside of this study? How do you feel about the use of imagery in general? Do you feel it helped you and how so? Do you feel there was a difference between the two types of imagery and if so what were they? Will you continue imagery use?

Procedures
The pitchers’ completed MIQ-R instruments; later on, their scores were collected and recorded by number, both to protect confidentiality and to help ensure random selection of participants. Pitchers completing the MIQ-R were also given a brief explanation of what the instrument covered and directions for providing answers. A 7-point Likert scale was employed for each question, and the points assigned each question were totaled for each participant. Using the scores obtained, 3 participants were chosen at random from the top 20% of scores, and another 3 were selected randomly from the bottom 20%; the 6 were asked to participate in the study. By omitting participants with middle-ranking scores, the study sought to secure a sample that truly represented high- and low-ability imagery skills. Participants signed a consent form or obtained written parental consent prior to participating.

Participants were asked to meet with an “observer” 5 times during the first week of the study, the period during which a stable baseline was to be established for each pitcher; after a baseline existed (which ideally required 1 week but in fact might have required more time), participant and observer were to meet 4 times during each of the next 3 weeks. The 3 weeks constituted the invention portion of the study. Prior to the intervention, each pitcher’s throwing performance was measured 5 times a week, until he had demonstrated a stable baseline, defined as an average score displaying no more than a 2-point variance in at least 3 consecutive trials. The first-week, baseline portion of the study was followed by imagery interventions beginning in the second week; each imagery intervention required 6 visits, or one and one-half weeks. Measurements were taken 4 times a week, post imagery session, during the imagery and video imagery intervention programs, until the study’s completion. Throwing-performance measurements were determined by averaging a pitcher’s scores for 10 pitches in the visitors bullpen of an NCAA Division I university. The measurement apparatus was placed in front of the bullpen home plate. During the baseline portion of the study, the Samsung Sports Camcorder SC-X205L/X210L was used to create video imagery segments for use during the intervention portion, with each pitcher wearing the “helmet-cam” module (placed aside his head, at eye level) and capturing his own internal perspective on the throwing of an accurate pitch. (At no time was any pitcher himself captured in a recording.) The module is worn comfortably on a headband, and no participate indicated discomfort during its use. The study design incorporated counterbalancing to eliminate sequence effects.

Participant 1 and Participant 4 experienced the cognitive imagery intervention during Week 1 of the intervention portion of the study, followed by video imagery intervention beginning in the middle of Week 2 (the two athletes’ seventh study session). Participant 2 and Participant 5 experienced video imagery sessions as the initial intervention during Week 1 of the study’s intervention portion. They participated in cognitive imagery intervention during Session 7 through Session 12. The throwing accuracy of Participant 3 and Participant 6 was measured 4 times a week, and they received no intervention, serving as a control group.

The university’s Mental Edge Training Facility was used for the video and cognitive imagery sessions, which were conducted individually (rather than in groups) during scheduled time slots. An imagery session was of a 10-minute (approximately) duration. During the video imagery interventions, participants were asked to watch the previously recorded 10-point pitch while imagining accompanying sensations, to include sounds, smells, tastes, and textures, in as much detail as possible. During the cognitive imagery interventions, in contrast, they were asked to imagine the 10-point pitch as vividly as they were able, again using the five senses as much as possible. At the study’s end, each participant completed the Post Study Imagery Questionnaire, providing insights into his attitudes towards imagery generally, as well as his unique responses to imagery practice, performance, or similarly related issue. The Post Study Imagery Questionnaire also attempted to determine whether and why players would continue to practice imagery techniques.

Data Analysis
Data were represented graphically to describe each participant, then reviewed for practical differences in throwing accuracy. Ocular statistics (Carboni et al., 2000) were reviewed by a group of trained researchers to determine actual changes in throwing accuracy and to provide control of the researcher’s bias. Qualitative results of the Post Study Imagery Questionnaire were collected and reported.

RESULTS
Data collected for this study were evaluated using mixed methodological procedures from ocular statistics (Carboni, et al, 200); additionally, they are explored in qualitative terms. Figures 1–6 will illustrate the participants’ throwing performance scores over the length of the study. Figures 7–12 will illustrate perfect pitch count scores over the length of the study.

The participants provided qualitative reports concerning imagery effectiveness (with the exception of Participant 3 and Participant 6, the control group receiving no intervention).

Participant 1
Participant 1 initially received cognitive imagery intervention (Cognitive Imagery First). Participant 1 had demonstrated a 2.9 (SD= 4.5, 3.6, 3.9) throwing performance baseline during the first week of the study; with one exception, each of his throwing performance scores fell above that baseline, ranging from 3.2 (SD= 3.9) to 3.9 (SD= 4.6) (See Table 1). The exception occurred in Session 8, for which the participant’s accuracy score was 1.4 (SD= 1.8). While this score was below the participant’s baseline, it was not beyond the margins of implied change set, for this study, at .9 (See Figure 1).

Czech - Figure 1
Figure 1. Participant 1 (high-ability): Accuracy scores (imagery/ video Imagery)

As the participant completed subsequent video imagery interventions, the accuracy scores remained above the baseline, ranging between 3.5 (SD= 3.7) and 5.3 (SD=3.7); throwing performance scores in Session 14 reached 5.3 (SD= 3.7), exceeding the margins of implied change, set at 4.9. During the baseline portion of the study, Participant 1 recorded between 1 and 2 perfect pitches (See Table 2), a rate maintained throughout the study, except during the imagery intervention portion, Sessions 6 through 11. During the imagery intervention portion, this participant’s perfect pitch count ranged from 0 to 3 (see Figure 7).

Post Study Imagery Questionnaire
Participant 1, who said he had never used imagery prior to entering this study, reported that he used imagery while playing in a game during the period of the study. He stated, “I would like to continue using imagery and practice it more before games. I feel like it really helps when I start rushing.” Participant 1 further reported that breathing techniques included in the relaxation portion of the imagery script helped him manage momentum and refocus his effort. Participant 1 expressed the opinion that video imagery was relatively more helpful in bringing about desired outcomes, although he found it difficult to mentally re-create accompanying sensations during the video imagery sessions.

Participant 2
Participant 2 initially received video imagery intervention (Video Imagery First). Participant 2 had established a baseline score of 1.0 (SD= 1.9) within the first week of the study; his throwing performance scores increased slowly during the first intervention, ranging from 1.4 (SD= 2.3) to 4.1(SD= 5.1) (see Table 1). Each of Participant 2’s throwing performance scores fell above the baseline; during Session 11, his score exceeded the established margins of implied change (see Figure 2).

Czech - Figure 2
Figure 2. Participant 2 (high-ability): Accuracy scores (video imagery/ imagery)
During Session 12 through Session 17 (the imagery intervention), all of Participant 2’s scores remained above the implied margin of change, which was set at 3.0; his scores ranged from 4.0 (SD= 3.7) to 5.1 (SD= 4.1). While establishing a baseline score during Session 2 through Session 5, Participant 2 recorded from 0 to 1 perfect pitch per session (See Table 2). During the video imagery intervention, his perfect pitch count remained at 0 until Session 10, when he threw 4 perfect pitches; in Session 11, he threw 1 perfect pitch. During the imagery intervention, which was his final intervention, Participant 2 threw either 2 or 3 perfect pitches per session (see Figure 8).

Post Study Imagery Questionnaire
Participant 2 reported never having used imagery prior to the study, but said he is currently employing it during games because his pitching performance improved following the start of the study. He stated, “I haven’t walked anybody, it must be working. I started trying to see the ball go where I want it to before I throw the pitch, and it really seems to help.” Moreover, Participant 2 expressed a desire to continue using imagery, for its benefits both to his accuracy and his confidence.

Participant 3
Participant 3 did not participate in any intervention (No Interventions). He had established a baseline score of 3.8 (SD= 3.6) within the first week of the study. During Session 6 through Session 11, his throwing performance scores ranged from 1.0 (SD= 1.9) to 4.1 (SD= 3.9) (see Table 1). All of these scores fell below his baseline score, except the Session 11 score of 4.1 (SD= 3.9). During Session 10, the participant scored 1.0 (SD= 1.9), dropping below the margin of implied change, set at 1.8 (see Figure 3).

Participant 3’s throwing performance scores in Sessions 12–17 ranged from 1.0 (SD= 1.9) to 2.7 (SD= 4.3), falling below his established baseline. During Session 13 through Session 16, this participant’s scores descended to the level of the margin of implied change. During the baseline portion of the study, Participant 3 threw either 2 or 3 perfect pitches per session. Across the remainder of the study, however (Sessions 6–17), Participant 3 threw 0, 1, or 2 perfect pitches per session (see Figure 9).

Participant 4
Participant 4 received cognitive imagery intervention first (Cognitive Imagery First). Participant 4 had established a baseline score of 4.3 (SD= 3.8) in the first week of the study, and during the first intervention, his throwing performance scores largely fell below that baseline, ranging from 1.8 (SD= 2.4) to 4.5 (SD= 4.7) (see Table 1). Session 11 comprised an exception.

Participant 4’s Session 11 score was 4.5 (SD= 4.7). During Session 7 and Session 8, the participant’s scores were 1.8 (SD= 2.4) and 2.1 (SD= 2.0), respectively, falling below the implied margin of change, which was set at 2.3. During Sessions 12–17, Participant 4 received video imagery intervention. His throwing performance scores for those sessions ranged from 3.3 (SD= 2.4) to 4.5 (SD= 3.5), and most fell below his baseline score, although his scores for Session 16 and Session 17 was 4.5 (SD= 4.1, 3.5) (see Figure 4).

Figure 4. Participant 4 (low-ability): Accuracy scores (imagery/video imagery)

During the baseline portion of the study, Participant 4 threw between 0 and 2 perfect pitches per session, a range he would go on to maintain for the duration of the study, excepting only Session 11, during which he threw 3 perfect pitches (see Figure 10).

Post Study Imagery Questionnaire
Participant 4 reported that he had used imagery prior to this study; he furthermore reported having difficulty sustaining the vividness of imagery. He went on to express a preference for having a detailed imagery script read to him, due to such reading’s capacity to generate vivid images. Participant 4 stated, “I usually do imagery before my games that I know I’m going to be pitching in. It helps me get focused, and I want to get better at it.” Participant 4 expressed a desire to continue imagery use, but made no note of any distinction between the cognitive and video approaches.

Participant 5
Participant 5 received video imagery intervention first (Video Imagery First). Participant 5 had established a baseline score of .8 (SD= 1.3) in the first week of the study. His throwing performance scores during the first intervention ranged from 1.2 (SD= 3.2) to 4.8 (SD= 4.6), above the baseline score he had produced (see Table 1). In Session 8 and Session 9, Participant 5 recorded scores of 3.3 (SD= 4.7) and 4.8 (SD= 4.6), respectively, exceeding the margin of implied change, which was set at 2.8 (see Figure 5).
Czech - Figure 5
Figure 5. Participant 5 (low-ability): Accuracy scores (video imagery/ imagery)

During Session 12 through Session 17 (the imagery intervention portion of the study), Participant 5’s throwing performance scores ranged from 2.5 (SD= 4.0) to 4.0 (SD= 4.1). All scores thus fell above his baseline score, and his scores in Sessions 14–17 exceeded the margin of implied change, coming in between 3.5 (SD= 4.6) and 4.0 (SD= 4.1). During the baseline portion of the study, Participant 5 threw 0 perfect pitches. During Session 9 in the video imagery portion of the study, he threw 3 perfect pitches; in Session 10 he threw 1 perfect pitch; in Session 11 he again threw 3. Over Sessions 12–17, the participant threw anywhere from 0 to 2 perfect pitches (the 0 was recorded during Session 12; for each of the next 5 sessions, a 1 or 2 score was recorded; see Figure 11).

Figure 11. Participant 5 (low-ability): Perfect pitches thrown

Post Study Imagery Questionnaire
Participant 5 reported never having used imagery prior to the study. He reported considering adherence to use of pre-game imagery following conclusion of the research project. Participant 5 reported noticing not only improved throwing accuracy, but increased self-confidence as well. He stated, “When I stop between each pitch, take a breath and see where I want the ball to go, it helps me to refocus. Also, when I do throw a bad pitch, it doesn’t carry over as much. I don’t get caught in a bad momentum. I am more able to release the last pitch and trust the next one, because I’ve seen myself throw it where I want to put the ball (in my head) many more times before. I know I can do it.”

Participant 6
Participant 6 belonged to the control group (No Intervention) and established a baseline score of 3.4 (SD= 3.1) during the study’s first week. His throwing performance scores ranged from 1.0 to 4.4 over Session 6 though Session 11 (see Table 1). With the exception of a 4.4 (SD= 3.4) throwing performance score in Session 9, Participant 6’s subsequent scores fell below his baseline score. During Session 10, Participant 6 recorded a throwing performance score of 1.0 (SD= 1.9), below the set 1.4 margin of implied change (see Figure 6).

Czech - Figure 6
Figure 6. Participant 6 (low-ability): Accuracy scores (control; no intervention)

Participant 6’s throwing performance scores for Sessions 12–17 were between 1.0 (SD=1.9) and 2.4 (SD= 3.6), all falling below the baseline. Moreover, in Session 14, the participant scored a 1.0 (SD= 1.9), which fell below the margin of implied change. While establishing his baseline score for this study, Participant 6 threw 0 perfect pitches. In Sessions 6–11, he threw from 0 to 2 (in Session 9) perfect pitches per session. For the remainder of the study (Sessions 12–17), he threw 0 to 1 perfect pitch per session (see Figure 12).

DISCUSSION
The purpose of the present study was to see whether imagery would have an effect on the throwing performance of individual baseball pitchers. Further, the present study sought to determine if individual variation in ability to “image” is associated with distinct responses to cognitive imagery interventions and video imagery interventions. By the end of Session 9, study Participants 1, 2, and 5 demonstrated higher scores (as compared to their individually established baseline scores) for throwing accuracy. This result parallels similar single subject sport-and-imagery research (Kearns & Crossman, 1992; Munroe-Chandler, Hall, Fishurne, Shannon, 2005; Shambrook & Bull, 1996; Templin & Vernacchia, 1993, 1995; Stewart, 1997, Carboni et al., 2000;). There should be further investigation into the effectiveness of brief interventions, because no research to date answers the old question of how frequent and how long intervention must be to produce the desired result (Cumming, Hall, Shambrook, 2007; Thelwell, Greenless, & Weston, 2006). The suggestion has been made that, as in the realm of physical skills, psychological-skills practice effects positive change only after an extensive investment of time (Weinberg & Williams, 2001). Thelwell, Greenless , and Weston (2006) found that combining three types of intervention—imagery, self-talk, and relaxation—produced results within a 3-day period, when 1 day of imagery training was provided and when measures were taken once weekly over a 9-match period. Murphy (1990) recommends intervention sessions of no more than 10 minutes’ duration, and Weinberg and Gould (2007) suggest providing intervention 3 to 5 times a week. Bull (1995) found that positive results ensued from a 4-week training period featuring 8 training sessions. Some researchers have examined intervention frequency and length by leaving participation to the discretion of the participant and recording objective reports; sessions as brief as 1 minute were noted (Carboni et al., 2000). Cumming, Hall, and Shambrook (2007) concluded that overall use of imagery could be increased with interventions as brief as a “workshop.” Findings from the present study indicate that, to be effective for specific tasks such as accurate pitching, imagery interventions can be as brief as 10 minutes in length, conducted 4 times weekly for 3 weeks.

The present study did not find participants to be affected distinctly by the two types of intervention (cognitive and video). The higher throwing performance score recorded for the final 6 sessions of the study are believed to reflect the lengthening period of time during which participants had practiced imagery practice, rather than to the type of intervention, since all participants receiving intervention responded similarly, whether they were in the Cognitive Imagery First group or Video Imagery First group. Gordon, Weinberg, and Jackson (1994) found similar results, investigating “internal” as opposed to “external” imagery. Future research into the effects of multiple interventions should seek to determine the relationship between effectiveness and time invested in each intervention.

Research has shown that imagery ability is a large determinant of how an individual’s physical performance will respond to imagery interventions (Hall, 1998). In the present study, however, scores for Participant 2 and Participant 5 (on both throwing accuracy and perfect pitches) improved more than they did among the other participants. That Participant 2 and Participant 5 succeeded more markedly with imagery use cannot, however, be attributable to higher-ability imagery, because Participant 2 was a high-ability imager while Participant 5 was a low-ability imager. Any individual, regardless of imagery ability, can benefit from imagery practice, although those with lower ability may continue to experience greater difficulty creating and controlling vivid imagery (Magill, 2007). Each high school level participant from the present study had a baseline score for throwing accuracy that was lower than the lowest such score established by a college level participant. Isaac and Marks (1994) and Piaget and Inhelder (1971) concur that imagery ability is developed by age 7. Moreover, Payne and Isaacs (1995) report that the highest level of cognition and abstract thinking develops at age 11–12. Participants 2 and 5 had a mean age of 17, beyond the developmental period and ranking them developmentally equal to the college level participants. The distinct intervention responses of Participants 2 and 5, then, are not due to the basic development of ability to image. Research on imagery use has found differences associated with subjects’ athletic competitive levels (Barr & Hall,1992; Salmon, Hall, & Haslam, 1994; Vadocz et al., 1997). These differences seem to be shaped by factors like years of experience, degree of motivation to play, degree of motivation to use imagery, and ability to create and control images.

Thelwell, Greenless, and Weston (2006) discuss ways in which distinct levels of goal orientation affect players’ levels of investment in imagery use. Research also finds that athletes exhibiting moderate to high levels of task and ego orientation become more invested in imagery use, in turn increasing how often they practice imagery (Cumming, Hall, Gammage, & Harwook, 2002; Harwood, Cumming, & Hall, 2003). Bull (1995) examined the effects of a 4-week mental training program on varsity athletes, finding that better-motivated athletes were likelier to adhere to an imagery program, and that less-seasoned athletes were likelier to be the better motivated. It is possible that Participants 2 and 5 in our study, being at one of the earliest stages of an athletic career, were better motivated than Participants 1, 3, and 4, who were playing what they anticipated would be the final season of their careers.
Motivation can also be affected by fatigue and overtraining. The participants in the present study all were at mid-season, obligated to a vigorous training schedule as well as to the study sessions. At least one point during the study, every participant reported feeling fatigue or exhaustion, and this might have affected their concentration and performance. A perceived imbalance between demands on athletes and their response capabilities sometimes creates the negative physical and emotional state known as burnout (Creswell & Eklund, 2006). As Creswell and Eklund (2006) state, insufficient “rest and recovery periods” will also help generate negative experiences. Participants in the present study might possibly have found that study-related testing and intervention consumed the time they normally would use for recovery and rest, which could account, to some degree, for periodic “off” performance, including uncharacteristically low accuracy scores, trending down of accuracy scores, loss of interest in the study, or transfer of effort from the study to some other task. The performance of Participant 3 and Participant 6 support such an interpretation; these two athletes received no intervention and saw their performance fall off over time. “Burnout” may also help describe the expressed attitudes of Participants 1, 3, 4, and 6.

The study’s timing during the athletes’ season may help explain any shortages of focus or concentration on their part, but additional distractions should also be considered. During video imagery intervention sessions, for example, certain participants showed clear difficulty in focusing when they opened their eyes at the conclusion of the relaxation portion in order to view video. The discrepancy arose even though all of the imagery sessions took place in the university’s Mental Edge Training Facility, where each participant was assured of experiencing interventions of identical length. To better maintain focus and a relaxed state, future research might employ a different viewing method (e.g., use a dark room into which video is introduced from outside or use virtual-reality gear). Furthermore, researchers would be well advised to employ a vivid script that helps participants to incorporate as many types of sensation as possible (Thelwell, Greenless, & Weston, 2006). The script used in the present study instructed participants to “see” only the target’s center box, which perhaps explains in part why Participant 2 and Participant 5 were able to throw more perfect pitches (see Figure 8 and Figure 11).

For the present study, throwing performance was defined as a pitcher’s ability to throw a ball at a specified area deemed the target. In measuring throwing performance, the mean score for the 10 pitching efforts made each session was recorded and graphically represented. Perfect pitches were defined as those hitting the center target, and they too were recorded and graphically represented; a perfect pitch received a score of 10 points.
There are various definitions of what performance enhancement actually is. Some individuals may look for greater consistency, more pitches thrown closer to target, when seeking evidence of performance enhancement. Others may see enhanced performance in a combination of more pitches thrown at the actual target, and lower-scoring pitches. For the present study, the mean score and number of perfect pitches thrown for each session were used to measure performance response. During cognitive imagery interventions, participants were asked to envision throwing only to the center box, while during video imagery interventions, they watched tapings of pitches thrown to the center box. An increase in pitches to the center box was, for this reason, said to indicate imagery intervention’s positive effects on throwing performance.

Two limitations on the present study resulted from the data collection process. First, during the intervention sessions, participants were exposed to extraneous noise, although none directly identified this as a distraction. In future studies, areas free of extraneous noise should be employed. Second, when a participant was unable to join in throwing performance measurement or imagery intervention session during daylight hours, the researchers accommodated his schedules by conducting these activities after dark, an inconsistency which, by potentially affecting vision, perhaps also affected success. Furthermore, time of day bears on the level of concentration and fatigue.
Results obtained through the Post Study Imagery Questionnaire describe perceived positive effects imagery wields on athlete performance and confidence. This questionnaire also documents that participants’ appreciation for psychological skills training grew during the study. These findings parallel past research (Carboni et al., 2000; Kearns & Crossman, 1992; Shambrook & Bull, 1996; Templin & Vernacchia, 1993, 1995; Stewart, 1997; Thelwell et al., 2006). Participants 1, 2, and 5 expressed an outlook positive toward the imagery sessions, toward their own confidence concerning tasks, and toward anxiety-reducing effects of mentally re-creating a pitching sequence. This supports numerous findings about imagery’s possible benefits, for example improved self-confidence (Callow, Hardy, & Hall, 2001), better motivation (Callow & Hardy, 2001), improved regulation of arousal (Hecker & Kaczor, 1988), and stronger ability to modify such cognitions as self-efficacy (Feltz & Ressinger, 1990). Imagery, or mental practice, can, the research record demonstrates, be used to control anxiety and to enhance both the strategies and physical movements that will be employed in performing a skill (Magill, 2007).

Suggestions for future research include, again, the deployment of alternative methods of presenting video imagery intervention, to ensure participants’ focus is maintained. In addition, future research should examine how often and for how long interventions are best administered, in terms of performance enhancement.

The baselines established by this study’s participants did not vary more than 1 point, although the criterion we employed for defining baseline and actual change was 2 points (on a 10-point scale). Perhaps future research would benefit from more strict criteria, which would tend to identify more pronounced effects.

Psychological skills training, coaches and athletes often fear, entails a long-term commitment and many field practice hours lost. The present findings, however, imply that imagery training’s effects on at least the one position-specific task studied are observable in as little as twelve 10-minute sessions (4 per week for 3 weeks). Moreover, the study demonstrates that effective intervention may take place during the competetive season and in conjunction with rigorous physical training.

Bull (1991) identified three barriers between athletes and ongoing psychological skills training: time constraints, a disruptive home environment, and an unmet need for individually tailored training. The position-specific intervention employed in this study, together with use of a brief script, alleviate all three problems. Later, in a discussion of how best to implement psychological skills training, Shambrook and Bull (1999) emphasized the importance of time management, of structure, and of integration of psychological skills within existing training. The present study’s findings, past research focusing on workshops (Cummings, Hall, & Shambrook, 2007), and future research will complete the path around the barriers, driving home that intervention programs may be both brief and integrated within established physical training in order to reap positive returns.

NCAA Athletes and Facebook

January 7th, 2008|Contemporary Sports Issues, Sports Management|

ABSTRACT
The use of Facebook and other social networks by a majority of National Collegiate Athletic Association (NCAA) athletes has come under intense scrutiny from college officials in recent months. The current level of monitoring by athletic departments ranges from mere advisories as to what athletes should post, to a complete ban on the use of any social networks (Brady & Libit, 2007). The findings of this study of 522 NCAA athletes representing Division I, II, and III indicate that NCAA II athletes project the least positive image on their Facebooks. Female athletes in general reported projecting a better image, while male athletes expressed the greatest resistance to being monitored.

NCAA ATHLETES AND FACEBOOK
The use of Facebook and other social networks, accessed regularly by the majority of National Collegiate Athletic Association (NCAA) athletes has come under intense scrutiny from college officials in recent months. The scrutiny has been prompted by athletic department administrators and coaches as they have become increasingly concerned about both the university image projected on Facebook and the well-being of the student-athlete. The current level of monitoring by athletic departments ranges from advisories as to what athletes should post, such as the ultimatums on type of use issued by the University of Kentucky and Florida State University, to a complete ban on the use of Facebook by athletes, as seen at Loyola University (Brady & Libit, 2007). For purposes of this article, it should be noted that the social network Facebook is a word frequently used by university administrators and athletic directors as an all-encompassing term that describes not only Facebook, but MySpace and other forums such as SportsGist.com, MyStack.com, and Badjocks.com. Such will be the case in this paper, as Facebook is the most prevalent social network utilized by college students today.

The focus of this article is to address the image and monitoring concerns associated with Facebook usage among college athletes. The secondary issue examined is the host institution’s concern over the image projected on the athlete’s social network accounts. Additionally, the battle between the university monitoring of student-athletes’ Facebook accounts and First Amendment privileges related to freedom of speech and expression will be addressed.
When a student creates a Facebook profile, he or she has the freedom to share uncensored photos and personal information with friends and other network members among the 40 million users (Lemeul, 2006). Facebook has evolved from a single-university communication tool into a public domain, accessible to anyone with a Facebook account. Facebook has certainly become a vehicle for self-expression and communication among students.

The NCAA has not taken a formal stand on how much a university can monitor or restrict accounts. Instead, the NCAA has left it up to the host institution to determine its own Facebook policies at this time. Universities have traditionally supported the 1972 Supreme Court ruling in Healy v. James wherein the Court found that state colleges and universities are not enclaves immune from the sweep of the First Amendment (Lukianoff & Creely, 2007). However, the recent trend is for universities to make specific policy statements related to expression on Facebook. The growing trend in athletic departments, as well, is to monitor the social network accounts of athletes. For example, Roper (2007) noted that the entire Catholic University lacrosse team was suspended from school after posting hazing photographs of new athletes on their personal Facebook accounts. Four female soccer players at San Diego State University were penalized for alcohol- and partying-related pictures they posted (Schrotenboer, 2006). Two athletes at the University of Colorado were issued tickets for harassment by the campus police for racially offensive messages they posted (Brady & Libit, 2006). In May of 2006, two athletes were dismissed from the Louisiana State University swim team for posting degrading comments about the swim coaches (Brady & Libit, 2006). Recent photos on Badjocks.com resulted in an increased scrutiny of athletes from Elon University and Northwestern University, as these postings projected an embarrassing image for the respective universities (Anderson, 2007). Laing Kennedy, the athletic director at Kent State University, made headlines when he forbade student-athletes there from using Facebook (Read & Young, 2006). Mr. Kennedy has recently revised his statement and simply requires all Kent State University athletes to keep their profiles private (Read & Young, 2006). Even though athletes seem to be at risk, Schrotenboer (2006) noted that coaches may be the ones who have even more to lose, as damaging pictures and statements on Facebook can hurt recruiting, team morale, and image.

Excessive access to information can put the athlete at risk by giving gamblers personal information about the injuries of marquee players, who are the most likely to be approached with point-shaving opportunities. There is also concern that a Facebook “friend” may turn out to be a professional gambler or agent and thus compromise an athlete’s eligibility by his or her affiliation with that person (Strickland, 2006). Agents or bookies may pose as a friend on a social networking site and solicit illegal contact with a student. Some students use Facebook as an alternative to a paper diary. However, these students need to be aware that any material posted on Facebook may be retained by Google’s online cache, even after the material is deleted, according to Tracy Mitrano, director of information-technology policy at Cornell University (Read & Young, 2006). A cache allows material to be viewed through a search engine, even after deletion from sites such as Facebook (Mitrano, 2006). According to Mitrano, this online cache proved deadly for one student who applied for a full-time position after graduation. Even with experience and a high grade point average, the applicant was refused employment when the employer found an inappropriate remark made by the applicant in an on-line cache. Not only can students impair themselves professionally with questionable pictures, but they can also incite legal action with libelous comments about professors or fellow classmates (Mitrano, 2006).

Ironically, at the same time many athletic departments are restricting the use of social networks, some tout the benefits; some claim that these networks may reduce the new-roommate anxiety experienced by incoming freshmen, open doors for conversation with their intended roommates even before arriving to campus, and aid in the completion of academic assignments (Farrell, 2006). Facebook can also aid students in meeting other people who share the same interests or dormitory. With the instant opening of an account, Facebook lists all of the people in a network who have a common interest. Students can also specify the networks to which they belong and even join networks based on characteristics such as metropolitan location or where they graduated from high school (Zuckerberg, 2006). Barbara Walker, senior associate athletic director at Wake Forest University, touted the positive attributes of Facebook when used innocently and suggested that administrators be careful about restrictive policies (Doughtery, 2007).

Politicians have even created accounts on social networking sites such as Facebook to spark interest among college-age voters (Vascellaro, 2006). This can be advantageous if the politician garners overwhelming support and positive comments from young voters. However, the political strategy of creating a Facebook profile can have the same negative consequences as for an athlete, when negative comments are posted on the profile of a politician.
While there are numerous benefits to creating a Facebook profile, there are concerns, not only about NCAA athletes but about the general student body, as well as in regard to projecting negative images (Read & Young, 2006). According to Pablo Malavenda, associate dean of students at Purdue University at West Lafayette, some students have little or no concern about the image they project to the public through Facebook (Read & Young, 2006). Malavenda noted that students tend to embellish profiles with exaggerated pictures of rebellion that most commonly involve underage alcohol consumption. Facebook furthermore has been used to taunt and physically threaten opponents in high school sports (Doughtery, 2007).

While student-athletes are to be treated as general college students, they are frequently subject to additional behavioral guidelines as a condition for scholarship renewal. These guidelines are presented in the form of a code of conduct, which usually requires that athletes represent the university in a positive manner. Ian McCaw, the director of athletics at Baylor University, issued a formal memo to all student-athletes and student trainers that explained that material which other students often post on Facebook pages may be inappropriate for student-athletes’ pages (Brady & Libit, 2006). Wake Forest’s athletic department instructs athletes that no comments or pictures administrators deem inappropriate may be used on Facebook (Doughtery, 2007). Furthermore, Kermit L. Hall, president at the University of Albany in New York, says that students give up some freedom and become subject to regulations when they join an athletic team.

There is concern about the impact that social networking sites might have on grade point averages. One UCLA student realized that he was spending too much time on Facebook when his grade point average dropped a point and a half (Reed & Riley, 2005). One concerned parent of a high school student noticed that his daughter’s involvement with Facebook made two hours’ worth of academic work take eight hours to complete (Duffy & August, 2006). This is likely due to the distraction that social networking sites create. Student-athletes already must be more effective time managers than the average student. The student-athlete cannot afford to spend eight hours on a two-hour assignment because of time lost to Facebook. Logistically speaking, student-athletes have little time in their schedules for the abyss of Facebook, without incurring academic consequences.

Student-athletes are in a different situation than typical students, as they are much more visible in the public domain representing the university. Athletic departments, at their core, operate like businesses (Strickland, 2006). Athletes are the products that create the funds for the businesses. Coaches are always trying to market the athletic department and the university to prospective recruits and donors. Prospective recruits can often find mostly uncensored information about their future teammates on Facebook. Pablo Malavenda, the associate dean of students at Purdue, knows of several instances when athletes backed out of oral commitments because of what their future teammates had posted on Facebook (Read & Young, 2006). This could have devastating consequences for athletic programs. When recruiting high school athletes, college coaches spend time, energy, and money in order to sell the program to the athlete. Prospective athletes may become dissatisfied with a program after seeing Facebook pictures of their future teammates engaging in drinking, drug use, or other undesirable activities. Even though the NCAA has not developed specific policies for athletes about Facebook and other social networking sites, such sites are becoming an area of concern; the issue was on the agenda at an August 2006 NCAA meeting.
While the use of social networking sites has garnered significant media attention, research documenting student usage and image projected is sparse. The research into the motivations for social network usage by students comprises a study conducted by Michigan State University (Ellison, Steinfield, & Lampe, 2006). This study gathered data on Facebook usage through the administering of a survey to the entire student body (Ellison, Steinfield, & Lampe, 2006). One key finding from this study was that the amount of time spent on the Internet did not differ between those who were not members of Facebook versus those who were members (Ellison, Steinfield, & Lampe, 2006). Grade point averages also did not differ significantly between Facebook members and non-members (Ellison, Steinfield, & Lampe, 2006). While these results are revealing, one must remember that they are only representative of the Michigan State University student body, not of all college students. Additional research is needed on the habits of college students using social networking sites. Because of the high-visibility situations facing NCAA student-athletes, their use of social networking sites needs extensive study. As athletic departments increasingly monitor their athletes’ accounts, knowledge of usage, attitudes, and motives is of growing importance.

The research questions pursued in the present study were related to examining frequency of use, image projected, and attitude toward being monitored on Facebook, by gender and NCAA classification. The study examined NCAA athletes’ (a) responses related to perceived personal image projected; (b) responses related to the athletic department image projected by individual student-athletes on Facebook; and (c) desired level of athletic department monitoring of social network accounts. The problem of this study was to generate an updated, cross-sectional view of athletes’ stances on issues of image and responsibility related to social networks.

METHODOLOGY
This study examined college athletes’ usage of and attitudes toward Facebook. To obtain a representative sample of NCAA student-athletes, the subject pool was selected from six different NCAA Division I, II, and III universities.

The data was collected from athletes at each of the schools, with assurance of anonymity to the participants. Athletes completed the survey privately. Athletes were told that the word Facebook should be taken to mean all social networks including MySpace and Badjocks.com. The total number of subjects responding was 522. This consisted of 148 NCAA Division I athletes representing the Southeastern Conference, 146 NCAA Division II athletes from the Gulf South Conference and the Northern Sun Intercollegiate Athletic Conference, and 126 NCAA Division III athletes from the Southern Independent Athletic Conference. There were 308 male and 214 female respondents.

The data collected were analyzed using a Kruskal-Wallis test (Green & Salkind, 2003) to determine if the population mean responses differed based on gender or categorization as NCAA I, II, or III level. The respondents were asked to answer written survey questions about (a) their personal image projected on Facebook, (b) the image of their athletic department based on their personal Facebook account, and (c) the level of athletic department monitoring of Facebook they desired. The 0.05 level of confidence was set as the significance level.
The questionnaire utilized for this study was modeled after the Carnegie MellonUniversity survey of freshmen reported in 2006 (Tabreez & Pashley). Slight adaptations of the questionnaire were made to more appropriately reflect the present athlete-dominated subject pool.

RESULTS
Looking at the responses of the male NCAA athletes as contrasted to the female NCAA athletes, there was a significant difference (at the 0.05 level of confidence) for all items examined in this study, when using the Kruskal-Wallis test of significance. As seen in Table 1, these items included athlete’s perception of personal image projected on Facebook accounts, athlete’s athletic department image as influenced by personal Facebook accounts, and athlete’s recommended level of athletic department monitoring.

Also presented in Table 1, NCAA classification was associated with significant differences in athlete’s personal image presented on Facebook. No significant difference was observed, however, in responses related to athletic department image projected or recommended level of Facebook monitoring, when examined by NCAA classification.

When examining aspects of personal image presented on Facebook, some significant differences were found. As Table 2 shows, 85.1% of the female athletes, as contrasted to 65% of the male athletes, leaned toward a positive image projection on Facebook. No female athletes appraised their accounts as projecting a very negative image. Also, 74.6% of the female athletes reported that their accounts projected a positive athletic department image, as contrasted to 56.1% of male athletes (Table 3). The male athletes were more likely than the female athletes to recommend “definitely” no athletic department monitoring, or monitoring on a limited basis. Additionally, as seen in Table 4, 66.8% of the male athletes recommended no monitoring or limited monitoring, as contrasted to 58.3% of female athletes.

Among NCAA Division I athletes, no respondents indicated a perception of any negative image of their personal accounts, whereas NCAA Division II and III respondents did report negative images, at rates of 4% and 7.7%, respectively. NCAA Division I athletes were most likely to say their accounts projected a neutral image, with 34.0% choosing this response. Also, as noted in Table 2, the NCAA Division III athletes had the highest percentage for positive personal image, 80.8%. They were followed by the NCAA Division II athletes, with 72.1%, and NCAA Division I athletes, with 63.8%.

DISCUSSION
The first Harvard University Facebook, distributed annually, was initially a simple, pictorial directory of all incoming freshmen. Along with pictures, the Harvard Facebook also included the majors and hometowns of freshman students. In 2005, Harvard student Mark Zuckerberg decided to launch an online version of the Facebook (Hoover’s, 2006). It started as a simple communication tool; then, Zuckerberg decided to extend online service to the entire Harvard student body and several other universities. It was after this point that Facebook exploded into the communication vehicle currently used by over two-thirds of American college students (Schrotenboer, 2006). Unlike the original Harvard Facebook, it has become a way for students to communicate and express their individuality, creating concern in collegiate athletic departments, particularly when individuality projects a negative self-image, team image, or university image. Facebook has become a medium through which student-athletes sometimes offer less-than-desirable information to the public.

Pop culture is created when (as on Facebook) users are allowed to share information with others exactly as they wish, uncensored, without regard for image and without fear of reprisal. The current trend, however, is for athletic departments and universities to restrict this free flow of expression, even, in a growing number of cases, to ban totally athletes’ use of social networks. Currently, the courts have not charged colleges and universities with violation of the First Amendment related to censoring social networks or restricting freedom of speech in student accounts. The issue will be interesting to follow.

As the present study found, female athletes generally claim to project a more positive image on social networks than their male counterparts. This finding alone might generate increased athletic department monitoring of male athletes’ Facebook accounts. Male athletes, furthermore, expressed more resistance to athletic department monitoring than did female athletes. This is another indication of the need to monitor male athletes’ accounts, since males seem to seek relatively more opportunities to exhibit a less-than-desirable image on Facebook.

The findings of this study for the various NCAA classifications suggest that NCAA II athletes are least educated about or least aware of the implications of the image issue associated with public accounts. This might have been expected, as these schools generally have less staff to work with athletes on image issues. The greater perception of a positive image projected on Facebook reported by NCAA Division III athletes is perplexing and deserves both accolades and further study. With the relative visibility of NCAA Division I athletics, it is to be expected that these athletes’ accounts would project a positive image, and they did, according to the athletes.

After investigating the issue of image and monitoring of college athletes’ personal Facebook accounts, it appears that several related matters need investigation. These are (a) whom athletes allow to access their accounts, (b) the privacy levels or protection levels athletes use with their accounts, (c) the motives of athletes for the images projected, (d) the steps athletic departments take to educate student-athletes and monitor their accounts, and (e) female athletes’ apparently greater concern about image on Facebook accounts, as contrasted to their male counterparts. Lastly, with the growing athletics-related abuse of Facebook in high schools, as seen recently at Medfield High School in Massachusetts and McCutcheon High School in Louisiana (Doughtery, 2007), study of high school policy is also merited.
