Differences of body dimensions in female volleyball players (cadets) in relation to volleyball playing position

Submitted by Aleksandra Vujmilović and Tamara Karalić

ABSTRACT
This research presents a test of the hypothesis that there are differences in morphological characteristics, which affect effective realization of the elements of the game, which are influenced by many factors from the area of anthropological status of the volleyball players. The study examines the relations of body-dimensions of cadet female volleyball players and provides the answers to a question of how different are they in that segment, depending on which position in the team they play. The research was conducted on a sample of 55 female volleyball players. The sample was grouped as follows: opposites, middle blockers, outside hitters, setters and liberos. To determine the physical size differences between groups, the authors used the univariate analysis of variance (ANOVA), while for the precise determination of the sources of variability between groups the authors used a Post Hoc analysis, Tukey HSD test as a method of multiple comparisons. A model of physical dimensions was used, that contains the five (5) variables: body height (ATV), range of hands (RAR), body weight (ATT), maximum reach with one hand from a place (MDOH1RM) and maximum reach with two hands from a place (MDOH2RM). With this model the differences have been found in body height (ATV) p=0.001, range of hands (RAR) p=0.003, maximum reach with one hand from a place (MDOH1RM) p=0.000, and maximum reach with two hands from a place (MDOH2RM) p=0.000. Based on the results of a post hoc analysis, statistically significant differences have appeared between the group Liberos and other groups of specialists. In scientific research practice there is a lack of research of this kind. In this sense, this research is conceived as a small contribution to the advancement of the profession especially in the domain of training technologies and optimal functioning of female volleyball players in training process, and manner of its planning and programming.

World Masters Games: North American Participant Medical and Health History Survey

Submitted by Mark DeBeliso, Joe Walsh, Mike Climstein, Ian Timothy Heazlewood, Jyrki Kettunen, Trish Sevene and Kent Adams

ABSTRACT

Athletes competing at the World Masters Games have either initiated exercise later in life or pursued a physically active lifestyle for an extended period. There is a paucity of information regarding the prevalence of chronic health disorders for this unique cohort of mature adults. PURPOSE: To investigate the different aspects of health of the Sydney 2009 World Masters Games North American participants. METHODS: An online survey was developed to investigate participant demographics, physiological measures of health, and medical health history. Questionnaire responses were collected from competitors representing 95 countries in 28 sports. Data were culled to focus on North American participants for comparison purposes (Centers for Disease Control and Prevention). RESULTS: A total of 928 participants from Canada and the United States (age 52.6±9.8 yrs) completed the survey, with 55% reported having previously competed in the World Masters Games. The top five sports were football (25.6%), track and field (15.4%), swimming (8.4%), volleyball (8.2%), and softball (7.8%). Very few (2.5%) reported currently smoking with an average of 65 cigarettes per week, while 13.6% were ex-smokers. Alcohol consumption (82.0% of the participants) averaged 4.7 drinks week, while 0.6% were ex-drinkers. The top five chronic disorders were rheumatoid arthritis or osteoarthritis (10.0%), hypertension (HTN 9.1%), hyperlipidemia (8.0%), asthma (6.5%), and depression (5.3%). Top three operative treatments were knee replacement or repair (12.2%), hernia repair (6.1%), and herniated disc surgery (2.0%). Top four prescription medications were anti-HTN (6.9%), thyroid hormones (6.6%), hypolipidaemic (6.0%), and medications to increase bone strength (5.9%). Prevalence was significantly lower versus the general US population for HTN, hyperlipidemia, arthritis, asthma, and depression (all p-values <0.01). CONCLUSION: Chronic disease and disorder indicators reported by participants of the 2009 World Masters Games were significantly lower versus the general US population. APPLICATIONS IN SPORT: Competitive sport in mature aged participants requires adherence with physical activity. Exercise adherence in competitive masters sport may promote successful aging and a counter measure to many chronic diseases.

Position-Specific Task, Strength, and Performance Comparisons between NCAA Division I Offensive and Defensive Linemen

Submitted by Garrett M. Hester, Bert H. Jacobson, Ty B. Palmer, Doug B. Smith and Matthew S. O’Brien

ABSTRACT

The ultimate goal of strength and conditioning practitioners is to improve performance on the field. To date, little data exist that provides evidence of strong relationships between selected exercises and sport-specific tasks. PURPOSE: The purpose of this study was to compare the performance of a position-specific task on the MAXX Football Sled Device (MX) between NCAA Division I offensive (OL) and defensive linemen (DL) and to determine the associations among selected strength and performance variables with results on the MX. METHODS: Offensive (n = 12) and defensive linemen (n = 14) (age 20.11 ±1.49 yrs) performed 10 “fire-off-and-drive” repetitions on the MX from a three-point stance. Data relative to force (N) and movement time (MT) was collected for each repetition on the MX. The duration between each repetition was automatically randomized between 6 to 10 sec. Strength and performance data including 1 RM of the squat, bench press, and power clean, along with vertical jump, 10 yd sprint, 40 yd sprint, and body fat percentage were gathered as part of seasonal standard assessment. RESULTS: Results yielded significant differences in body weight, sprint performances, 1 RM squat, and a near significant difference in MT (p = 0.052) between OL and DL. With respect to performance on the MX, there were no significant associations among selected strength and performance measures and MT on the MX. Although insignificant, force on the MX was found to have moderate associations with the 10 yd sprint (r = .457) and 1 RM power clean (r = .463). CONCLUSIONS: Primarily, these results point out that little carry over exists between the standard exercises performed and the task performed on the MX. Further research for the purpose of finding exercises that correlate with a position-specific task in these athletes is warranted. APPLICATION IN SPORT: A priority among practitioners is to remain cognizant of the positional role differences and distinct physical characteristics between OL and DL. The OL and DL positions should be categorized separately so that specific evaluative and training needs can be met for each position.

Advancements in Concussion Prevention, Diagnosis, and Treatment

Submitted by Gregory B. Bonds, William W. Edwards and Brandon D. Spradley

ABSTRACT

Concussions continue to be a mainstay topic of conversation among the media, health professionals, and the general public. In 2013, the American Medical Society for Sports Medicine (AMSSM) released a position statement that estimated as many as 3.8 million concussions occur within sports annually with up to 50% of concussion injuries unreported. Advancements in the areas of diagnosis, treatment, playing rules, equipment, education, and technology have heightened the awareness on the dangers of concussion injuries and the need to provide better protection for sports participants. The current (2014) position statement from the National Athletic Trainers Association recommends a thorough neurologic assessment for a “history of concussion, seizure disorder, cervical spine stenosis, or spinal cord injury”. In 2014, prominent organizations such as the National Collegiate Athletic Association (NCAA) and the National Football League (NFL) have taken a proactive approach to commission research projects to study the short term and long-term effects of concussion injuries. Results of these research efforts should enhance the welfare and protection of participants. The purpose of this paper is to review and explore advancements in concussion prevention, diagnosis, treatment, playing rules, equipment, education, and technology.

A Woman’s Guide to Climbing the Corporate Ladder: One Swing at a Time

Submitted by Justin Barnes, Scott P. Barnicle and Amber M. Lee

Abstract
Golf is a game played and enjoyed by millions, yet this enjoyment can quickly turn to frustration when psychological factors become overwhelming. More important, how one chooses to play and behave on the golf course may provide benefits to professional development if practiced properly. Grounded in sport enjoyment theory (Scanlan & Lewthwaite, 1986; Stodel, 2004), this study examines the difference in the psychological factors, which contribute to sport enjoyment and stress in female amateur golfers. With support from five state golf associations, this mixed-methods study (n=50) demonstrated statistically significant results regarding the socialization process of females in golf participation to better understand the purpose of a round, and to enjoy the experience more, regardless of performance. This research can help golf organizations such as the PGA and LPGA of America, PGM Programs, and developmental academies improve training and tailor instruction and marketing strategies to female recreational and professional golf populations. In addition, this research could serve as a guide to individuals, especially females who may use golf as a catalyst to enhance professional development as well as provide understanding to the positive relational impact a round of golf may have on participants.
