Health and Lifestyle Behaviors of U.S. Masters World Cup Field Hockey Players
The purpose of this study was to examine health and lifestyle behaviors of United States Masters field hockey athletes who competed in the Masters Field Hockey World Cup in 2018. A total of 122 athletes (72 women, 50 men) completed the 42-item Health and Well-being of Masters Field Hockey Athletes Survey. Mean age was 50.1±8.3 years (range = 35 to 71). Mean body mass index (BMI) was 24.9±3.1 kg/m2. Participants rated their health as very good/excellent (86.9%) and their stress as rare/not at all (56.6%), had no major health conditions (61.5%) or medication use (70.5%), and had at least one injury (53.3%). Participants consumed ≥2 fruits (68.9%) and ≥2 vegetables (83.6%) per day, daily breakfast (68.0%), ≤1 sugar-sweetened beverage (86.9%) and ≥7 cups of water (54.1%) per day, and ≤2 alcoholic beverages per week (59.8%). Participants reported ≥7 hours of sleep per night (65.5%), and no/little restless sleep (52.4%). Just under half of participants reported sitting ≥5 hours per day (46.7%). Exercise frequency at ≥3 days per week and ≥30 minutes per day was 95.9% and 98.4%, respectively, with jogging (68.0%) the most common mode. Well-being scores were high. Overall, Masters field hockey athletes are healthy and practice lifestyle behaviors conducive to positive health.(more…)

Ability for tennis specific variables and agility for determining the Universal Tennis Ranking (UTR): A Review and Recommendations
Our purpose was to investigate tennis specific measures to predict a player’s Universal Tennis Ranking (UTR) value and to see what percentage of the variables most influence the ranking. Methods: 15 male and 14 female athletes volunteered to participate in this study. Each volunteer performed no more than 16 total serves or eight from the add and deuce side down the “T”, no more than 16 total forehands and backhands down-the-line, three spider tests, and two trials of footwork taps in 30 seconds. Only the top two hits were analyzed. Results: A multiple linear regression was calculated predicting a player’s UTR based on serve, forehand, backhand, agility, and footwork taps. The regression equation was significant (F (5,23) = 29.66, p<.05) with an R squared value of 0.866. Coefficient of variation (CV) and intra-class correlation coefficients (ICC) were calculated to assess reliability between player serve (r=0.902), forehand (r=0.843) and backhand velocity (r=0.858), agility (r=-0.817), and footwork (r=0.472). More noticeable was the significant predictive value of serve (r=0.902) and backhand velocity (r=0.858) to the player’s UTR. Conclusion: These results underline the important relationship between the player’s UTR and tennis-specific characteristics (serve and backhand velocity) as assessed by the player’s stroke velocity. The ability of training regimens to improve tennis-specific metrics would improve performance qualities and the player’s UTR.(more…)

Branding in women’s sports: A literature review
The purpose of this study was to explore the gaps in the branding literature as it pertains to women’s sports. The review included 11 articles from sport management and business journals, investigating personal branding, team branding, and media coverage. Additionally, the review explored the practical implications as well as avenues of future research (i.e., conceptual model).(more…)

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…)
