Positive and Negative Events Predict Burnout and Engagement in Athletes and Non-Athletes

ABSTRACT

The researchers compared predictors of engagement and burnout in adolescent athletes and non-athletes by focusing on daily positive and negative performance-related events (e.g., performing well in team practice) and interpersonal events (e.g., sharing a laugh with teammates). Participants were recent high school graduates who retrospectively reported participation in high school sports or heavy investment in alternate activities (e.g., marching band). The athletes and non-athletes were similar in how many hours they practiced and competed each week, frequency of activity-related travel, and performance level. In addition, the two groups did not differ in the extent to which their high school identity and self-esteem were based on their participation. Results revealed no overall differences between the two groups on engagement or burnout. For both groups, positive performance events predicted activity engagement (characterized by dedication, vigor and enthusiasm).  However, the experiences of athletes versus non-athletes differentially predicted burnout (marked by emotional and physical exhaustion). In athletes, burnout related to both performance and interpersonal events. In non-athletes, burnout was only related to performance events. In addition, burnout was positively associated with coach focus on winning (a situation more common for athletes) and negatively associated with coach focus on fun (a situation more common for non-athletes). These findings indicate that experiencing positive and negative events is a precursor for engagement and burnout in high school athletes and non-athletes. Promoting positive (relative to negative) events during training, practice, competitions or performances could enhance benefits and prevent maladaptive outcomes of participation in extracurricular activities. Positive social interactions may be particularly important for preventing burnout in adolescent athletes.

Biomechanical Comparison of “Dead” and “New” Pointe Shoe in Female Professional Ballet Dancers

ABSTRACT

Purpose: Available research on pointe shoes often compare pointe shoes to other dance footwear, however there is a lack of studies comparing dancers’ biomechanics when using “new” pointe shoes and pointe shoes that have worn down, “dead”. The aim of this study was to examine the biomechanical differences exhibited by professional ballet dancers while performing relevé, sous-sus, and pirouette in “dead” and “new” pointe shoes. Methods: Thirteen female (20.9 ± 1.9 years old) professional ballet dancers were asked to perform three trials of relevé, sous-sus, and pirouette in “new” pointe shoes and “dead” pointe shoes. Center of pressure sway area and ground reaction forces in the anterior-posterior, medial-lateral, and vertical directions were recorded using one AMTI force plate. Results: The “dead” pointe shoe condition had significantly higher sway area during relevé, sous-sus, and single pirouette (103 ± 95 mm2; 256 ± 133 mm2; 178 ±129 mm2, respectively) than the “new” pointe shoe condition (50 ± 65 mm2; 110 ± 64 mm2; 77 ± 39 mm2, respectively),  p-value < 0.05. In addition, peak ground reaction force in the anterior-posterior direction during relevé movement was higher in “new” pointe shoes (35 ± 6% body weight) than in “dead” pointe shoes (32 ± 6% body weight), p-value = 0.019. No significant differences were observed for the other dependent variables. Conclusions: A larger sway area was observed in “dead” pointe shoes compared to “new” pointe shoes, which indicates that the participant had less balance in the “dead” pointe shoes than in the “new” pointe shoes. The larger sway area in “dead” pointe shoes may indicate that decrease in shoe integrity may contribute to decrease in the support and stability of the pointe shoe while the ballet dancer maintains the ‘en pointe’ position. Moreover, higher forces in the anterior direction state that the dancers can apply more forces in the “new” point shoe. Application in sport: These results can educate ballet teachers and ballet dancers about the mechanical changes in “dead” pointe shoes, which may lead to injury and reduce in performance. Furthermore, these results may lead to enhancements in footwear design.

Assessing the Dietary Quality and Health Status Among Division 1 College Athletes at Moderate Altitude

ABSTRACT

Student-athletes’ dietary habits are ingrained in a complex interaction as they seek to maintain the balance between student and athlete. Assessing the dietary habits and lifestyle factors associated with this highly demanding population is the focus of this study. Eighty-nine Division I Collegiate Athletes was assessed (age 19.84 ± 1.15 yr). Measurements included diet quality, body composition, blood lipid profiling, and wellness factors. Significant deficiencies in Vitamin D (football 6.68 ± 5.84; basketball 4.33 ± 3.17; swim/dive 4 ± 2.97; volleyball 4.07 ± 2.97) and Omega 3-EPA & DHA (football 125.84 ± 301.03; basketball 53.92 ± 48.05; swim/dive 29.45 ± 35.83; volleyball 42.79 ± 30.77), Calcium (swim/dive 1083.55 ± 437.88), and Potassium (swim/dive 1083.55 ± 437.88) were reported. All teams exhibited an energy deficit, however, the highest energy deficit was for football (-843.57 calories). All teams had higher than recommended levels of perceived stress, averaging 20.63, and swim/dive had higher levels of depressive symptoms (6.17 ± 3.30). All teams reported poor sleep quality, averaging 7.20. This assessment indicates variability in dietary quality and wellness factors among individuals and teams. Individualized guidelines should be recommended for those experiencing food intake challenges such as the unique needs of moderate altitude athletes.

Evaluation of Possible Anthropometric Advantage in Sit-Up Test

ABSTRACT

The U.S. Navy currently employs sit-ups as part of its semi-annual physical fitness in order to assess the abdominal muscular endurance of service-members.  However, there is speculation that sit-up performance may be associated with anthropometric proportions thereby affording certain service-members with a biomechanical advantage.  To test this theory, anthropometric measurements were taken at various sites (i.e., humerus, torso, femur, and tibia) across a convenience sample of 69 participants (37 male / 32 female), to include student, active duty, and retired military personnel from the United States Naval Academy.  Humerus length (r = .297), tibia length (r = .385) and sex (r = .314) were all found to be moderately correlated with sit-up performance.  These findings, coupled with well-documented concerns of the sit-ups in terms of safety and relevance in the literature, make a compelling argument for the identification and implementation of other potential field tests to assess abdominal muscular endurance.

Study on professional football players – factors in recovery and preparation and performance markers during scheduled training session

ABSTRACT

Purpose. The purpose of the present study is to estimate if the athletes can satisfy their energy needs by diet, if they are well hydrated before training, and if the training is effective.

Methods. Ten players of the football team in the B professional league participated in the study (age 23.44 ± 5.98 years, weight 70.64 ± 4.57 kg, height 176.4 ± 7.35 cm; ±SD). Their body composition was analyzed with the Body Composition Analyzer IoI 353 and they completed food questionnaires. Blood lactate concentrations were determined using the biochemical analyzer BIOSEN – C Line, EKF Diagnostic. The heart rates of the subjects are recorded using the activePULS, MEDION AG. Data was processed using SPSS and Graphpad Prism software.

Results. According to the data obtained from the food questionnaires all subjects received the necessary amount of energy to fully meet their energy needs. From the multiple linear regression, it is seen that the highest value has the standardized coefficient in front of the carbohydrate intake which means that it has the greatest influence (about 65%) on total energy intake. The heart rates of participants in the study range from 78 to 90% of the predicted maximum, i.e., high intensity. Differences in blood lactate concentration before and after exercise are significant, evidence of effective performance on training.

Conclusions. We can conclude that according to the nutrition questionnaire the athletes received a sufficient amount of macronutrients and sufficient amount of energy for their training needs. The change in blood lactate concentrations and heart rate during training is indicative of the responsible attitude of the players, and therefore the target endurance is most likely to be achieved.

Applications in Sport. Reported methods could be a useful tool for coaches to track the recovery and preparation of the athletes in season and to evaluate their performance during a scheduled training session.
