Concussions in Cheerleaders Reported from a Countywide Concussion Injury Surveillance System
The purpose of this study was to advocate for the acceptance of cheerleading as a sport so that its athletes are eligible for the same resources available to other sports, such as concussion education programs and injury surveillance systems. The subjects of this study were cheerleaders from Miami Dade County public high schools who sustained a sports related concussion (SRC) from August 2015 to June 2019, identified from the Miami Concussion Model Concussion Injury Surveillance System. The database is compiled from reports submitted by certified athletic trainers after a suspected concussion, from post-injury ImPACT tests, and from patients who present to the University of Miami Sports Concussion Clinic for evaluation. A total of 29 cheerleaders were identified. The 2018-19 academic year accounted for 45% of reported concussions, representing a large increase in number compared to previous years. This was observed after increased emphasis was placed on certified athletic trainers to report SRC in cheerleaders. On average cheerleaders with SRC were withheld from sport for 26.2 days, and 38% had prolonged recovery of >28 days. Cheerleaders perform complex athletic maneuvers that put them at risk of injury, particularly SRC. If considered a sport, cheerleading would be afforded the same benefits as other sports, including resources for better facilities, mandatory concussion education, ATC availability, baseline neurocognitive testing, and inclusion in injury surveillance systems. Increased knowledge of the long-term sequelae of concussions and repetitive head injuries has led to the development of concussion education programs and injury surveillance systems to protect athletes from these types of injuries. Although competitive cheerleading has been recognized as a sport, cheerleading as a whole has not, putting its athletes at risk as its participants are not included in these safety programs.(more…)

Comparison of BMI-based equations and plethysmography for estimating body fat in female collegiate gymnasts
The purpose of this study was to assess the utility of using BMI-based equations (BEQ) to estimate body-fat percentage (BF%) in female-collegiate gymnasts. As such, the agreement between BF% estimates with BEQ and air-displacement plethysmography (AP) were compared in twenty-two gymnasts (n = 22). Body mass, height, and BF% were assessed via AP and BEQ [Jackson et al. (JBMI), Deurenberg et al. (DBMI), and Womersley & Durnin (WBMI)]. Results: The assessments produced the following estimated BF%: AP = 20.3 ± 3.6%; JBMI = 26.9 ± 3.9%; DBMI = 26.4 ± 2.2%; and WBMI = 27.9 ± 2.5%. BF% estimated via AP was significantly lower (p < 0.001) than each BEQ. Weak correlations were found between AP and BEQ (JBMI, r = 0.12; DBMI, r = 0.07; WBMI, r = 0.12). The limits of agreement (constant error ± 1.96 SD) for each BEQ compared to AP were: JBMI = 6.6 ± 9.5%; DBMI = 6.1 ± 7.8%; and WBMI = 7.6 ± 8.0%. These results suggest a wide range of individual differences existed between BEQ and AP. Furthermore, BEQ significantly overestimated BF% relative to AP in this gymnastics population. Coaches and sport practitioners are in need of a quick, practical, inexpensive, and accurate method of body composition assessment. Based on this study, BEQ does not meet the needs of the practitioner when compared to AP. As a result, practitioners in the field need to consider other field methods of predicting BF% in collegiate female gymnasts.(more…)

Evaluating the Impact of Two-Game Road
Trips in College Sports: Does a Travel
Partner Scheduling Approach Affect Team Competitiveness?
Some NCAA athletic conferences have implemented a geographic travel partner strategy when scheduling league games. Teams are organized into two-team clusters. A visiting team comes to the region and plays both opponents during one road trip before returning to campus. Prior research reveals NBA teams tend to have a lower winning percentage when playing back-to-back games on back-to-back evenings. This study examines the performance of college sports teams on two-game road trips to see if the NBA pattern exists in college sports. Game results (and winning percentages) from the Sun Belt Conference for the 2016-17 season are evaluated over four sports (women’s soccer, women’s volleyball, women’s basketball, and men’s basketball). Team performance in Game 2 was comparable to Game 1 in women’s soccer, women’s basketball, and men’s basketball. Game 2 performance was improved in women’s volleyball. There was not a significant reduction in road team performance in Game 2 of two-game road trips when the quality of the opponent was introduced into the analysis of women’s soccer, women’s volleyball and women’s basketball. However, men’s basketball teams tended to win more often during Game 1 rather than Game 2 when playing comparable opponents. The travel partner scheduling model maximizes player rest, reduces travel time, and minimizes missed class time. This study suggests its implementation does not impact team competitiveness, particularly during Game 2 as found in the NBA. Conference personnel and university athletic administrators may take comfort that their drive to control costs and enhance the student-athlete experience is not impacting the competitiveness of their teams.(more…)

Aggressive Osteoblastoma of the Acetabulum in an 18-Year-Old Female Volleyball Player
In a case study, an 18-year-old female volleyball player presented with persistent hip pain. Imaging revealed a lesion in the acetabulum and follow up biopsies led to the diagnosis of a benign osteoblastoma. The patient underwent a surgical resection and open reduction internal fixation of the acetabulum. Aggressive osteoblastomas of the acetabulum are rare in a young, active population; therefore, clinicians must be able to recognize the need to refer for further evaluation and understand the importance of a multidisciplinary individualized plan of care to ensure a successful return to play for the patient.(more…)

Perceptions of Dry Needling for Performance & Recovery in NCAA Division I Athletes
The aim of this study was to examine the perceptions of dry needling within NCAA Division I athletes for muscle performance and/or recovery.Seventy-seven NCAA Division I Athletes completed an 15-item online survey sent via e-mail, which included demographics, exposure to dry needling, and perceptions of effectiveness. Those that had no experience of dry needling were asked to rate their perceptions and reasoning for non-exposure. The results indicated that 66% (n=51) of participants did not have experience with dry needling, while 34% (n=26) did have experience with dry needling. Athletes that experienced dry needling reported that dry needling was effective and comfortable for efficient and speedy recovery. They also reported that they would recommend others to use this recovery treatment. Those athletes with non-exposure to dry needling reported that they would rather use other treatments, concerned with pain or bruising from dry needling or was not sure it would work for recovery. These results help to fill current gaps in research on dry needling. Future research could compare treatment protocols for pain management and/or recovery effectiveness.(more…)
