Relationships Between BMI and Self-Perception of Adequacy in and Enjoyment of Physical Activity in Youth Following a Physical Literacy Intervention
Abstract
Purpose: The purpose of this research was to examine the relationships between body mass index (BMI) and self-perception of adequacy in and enjoyment of physical activity in youth following implementation of a six-week physical literacy (PL) intervention. Methods: Students (n=92) in grades 2-5 completed the Children’s Self-Perceptions of Adequacy and Predilection for Physical Activity (CSAPPA) scale pre- and post-PL intervention. The PL intervention program consisted of a weekly, 30-minute program conducted by trained individuals during the school day. This program focused on the mechanics of running, jumping, and throwing. Height and weight were measured pre-intervention to calculate BMI using the Center for Disease Control’s Youth and Teen calculator. Results: A significant interaction between CSAPPA score and BMI category was found, F(1, 82) = 4.948, p < 0.05). Students in the abnormal BMI category post-PL intervention CSAPPA scores were higher than their pre-PL scores. Conclusion: Based on the results, PL programming seems favorable in improving self-perception of physical activity selection in children with abnormal BMIs. Previous research has shown that students who do not feel confident performing a task are less likely to participate. Following the trend of decreased exposure to physical activity during school, it is possible that students with unhealthy BMIs are not getting proper exposure to the mechanics of movement. This scenario may lead to less physical activity participation and increases in unhealthy BMI ranges. Applications in Sport Fitness and Health: By teaching children that they can move proficiently, children may increase self-perceptions of physical activity and make more active choices which may attenuate increasing BMI trends and lead to future sport participation.

Servant Leadership and the Relationship to Autonomy, Competence, and Relatedness in Division I Athletic Departments
ABSTRACT
Purpose
The purpose of this study was to explore the relationship between observed servant leadership behaviors of Division I athletic directors and self-reported basic work-related psychological needs satisfaction of Division I administrative (e.g., non-coaching) athletic department employees. This study examined the relationship between servant leadership behaviors in Division I athletic directors and the three elements of basic work-related psychological needs satisfaction including autonomy, competence, and relatedness.
Methods
A sample of athletic department employees in 35 randomly selected Division I athletic departments (n = 230) were sent an electronic survey via email that included questions on demographics, the seven-item Servant Leadership Scale (SL-7), and the 12-item adapted Work-Related Basic Need Satisfaction Scale (W-BNSA).
Results
The results of this study revealed a statistically significant, positive relationship exists (p < .001) with observed servant leadership behaviors in athletic directors and the athletic department employees’ work-related psychological needs of autonomy, competence, and relatedness.
Conclusions
This finding supported the view that greater levels of servant leadership behaviors in Division I athletic directors were associated with greater work-related basic psychological needs satisfaction of Division I athletic department employees.
Applications in Sport
The results of this research provide an opportunity for athletic directors at the highest level of intercollegiate competition (Division I) to adopt a leadership style that can contribute to the three components of basic psychological needs satisfaction in their employees.

Relationships Among Muscle Characteristics and Rowing Performance in Collegiate Crew Members
Abstract
Purpose: The purpose of this study was to explore the relationships among measurements of muscle quality and rowing performance in college-aged club rowers. Methods: Ten men and women (mean ± SD: age: 22.1 ± 4.0 years; ht: 180.5 ± 8.3 cm; wt: 79.0 ± 13.5 kg) volunteered to participate in this study. Ultrasound images were collected at 50% thigh length in a transverse plane to quantify muscle size. The sum cross-sectional area (mCSA) of these muscles was reported. Bioelectrical impedance analysis (BIA) was conducted to predict fat-free mass (FFM) and estimate total leg lean mass. One-repetition maximum leg press (LPMAX) was recorded as well as vertical jump (VJHT; cm). Lastly, participants completed a 2,000m time trial on the rowing ergometer, where the 500m average split was used in analyses. Pearson’s product moment correlations were calculated across all variables and backwards stepwise linear regression was completed using VJHT, LPMAX, FFM, and mCSA as possible predictors of 500m performance. Results: The correlations coefficients among recorded variables were all very high and significant (r = 0.867-0.950; p = 0.001-0.04). The regression analysis indicated VJHT was a significant predictor of 500m time trial performance (R2=0.903; p<0.05). Conclusions: Although rowing may often be considered an endurance sport, the single best predictor of and the strongest correlation to time trial performance is vertical jump height as an index of power. Applications in Sport: Emphasis on plyometric training may serve as one of the most important aspects of athlete development beyond rowing form and mechanics, more so than strength or hypertrophy in collegiate rowers.

Exertional Rhabdomyolysis in a Female Collegiate Powerlifter with Type-1 Diabetes
ABSTRACT
Purpose: Investigate a case of exertional rhabdomyolysis (ER) in an athlete with Type-1 diabetes. Methods: The athlete shared relevant details from her training notebook, food journal, and medical information from the event with the researchers in a series of in-person interviews and electronic communications. The athlete’s food journal data was evaluated by a Registered Dietitian Nutritionist using computerized nutritional analysis program. The training program was evaluated by a Certified Strength and Conditioning Specialist in collaboration with the athlete to determine the precipitating factors for the injury. Results: Insufficient preparatory training, insufficient recovery, insufficient protein, and insufficient caloric intake were likely contributors to this ER injury. High caffeine intake, training in hot weather, and mild dehydration are also potential factors to an unknown extent. Conclusions: A well-organized, progressive return to heavy training is necessary to avoid musculoskeletal injury. In addition, athletes require appropriate nutrition to support the demands of heavy training and post-exercise recovery. While difficult to assess the extent at this time, athletes with diabetes could be at a higher risk for injury because of their health condition. Therefore, careful attention should be given to details of training, diet, glucose monitoring, and medication regimen, with supervision and education provided by trained professionals. Applications in Sport: This case study identifies specific precipitating factors of a rare case of exertional rhabdomyolysis in an athlete with type-1 diabetes. Knowledge gained from this case may be used to help other athletes prevent injury.

Use of Wrist Guards for Gymnasts – A Systematic Review
ABSTRACT
This systematic review was designed to provide the best current evidence regarding wrist guard use in gymnastics based on relevant biomechanical effects and injury prevention. Evidence supports the use of wrist guards as protective equipment in the prevention of gymnasts’ wrist pain and injury. However, potentially negative effects of wrist guards on proprioception and performance were also reported, and critical gaps in knowledge regarding guard design, most effective indications, and application to female gymnasts remain. Further biomechanical and clinical studies are needed to fill these gaps in knowledge toward making evidence-based recommendations regarding use of wrist guards in gymnastics.
