Comparison of BMI-based equations and plethysmography for estimating body fat in female collegiate gymnasts

ABSTRACT

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.

Evaluating the Impact of Two-Game Road Trips in College Sports:  Does a Travel Partner Scheduling Approach Affect Team Competitiveness?

ABSTRACT

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.

Aggressive Osteoblastoma of the Acetabulum in an 18-Year-Old Female Volleyball Player

Abstract

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.

Perceptions of Dry Needling for Performance & Recovery in NCAA Division I Athletes

ABSTRACT

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.

How Historically Black Colleges and Universities (HBCUs) Can Benefit From E-Sports While Adding Diversity into the Gaming Industry

ABSTRACT

Dr. Shaun R. Harper infamously came to the conclusion that “Perhaps nowhere in higher education is the disenfranchisement of Black male students more insidious than in college athletics” (7). This quote is not attributed to Historically Black Colleges and Universities (HBCUs), but to the power five conferences of Predominately White Institutions (PWIs). As of 2019, Black E-Sport coaches make up less than 2% of coaches at PWIs (20). Professional gaming or better known as E-Sports is not only a billion dollar industry (17), but has allowed for over $15 million dollars in collegiate scholarships to be awarded for the 2016-2019 school year (20). Yet, no Historically Black Colleges and Universities (HBCUs) have started an E-Sports team. HBCUs are excluding themselves from a billion dollar industry, while also failing to increase the diversity of E-Sports participators, coaches at PWIs and HBCUs, and Black professional gamers.  This paper has practical application as it provides convincing evidence as to why HBCUs could not only benefit from investing in E-Sports, but can help the professional gaming industry with its diversity issue.
