The majority of research regarding PAP has focused on the effects on maximal intensity movements, such as a vertical jump. There is limited information regarding the effects of PAP with the intent of improving submaximal muscular endurance performance. Purpose: The purpose of this study was to determine if a PAP warm-up (conditioning activity) would have a positive effect on the maximum number of repetitions one is able to successfully perform in the hex-bar deadlift (HDL) and barbell bench press (BP) at a submaximal intensity. It was hypothesized that the addition of a PAP conditioning activity to a dynamic warm up (DYN WU + PAP) would result in a greater number of repetitions performed compared to a DYN WU. Methods: Utilizing a repeated measures crossover design, eleven female NCAA track athletes participated in the six-session study. During the first ...

PCOS often goes undiagnosed or is misdiagnosed due to a lack of education, awareness, or communication of symptoms on the part of the woman and/or health care provider. The purpose of this study is to measure the prevalence of PCOS and to determine the current level of knowledge of this topic among female students attending a university in Utah. Data was gathered using an online survey that was distributed to biological females attending the university. The survey included measurements on the prevalence of females diagnosed with PCOS and the awareness of symptoms associated with PCOS. It also measured the various treatment techniques used to manage symptoms and the efficacy of those symptom management techniques. 351 respondents met the inclusion criteria and completed the entire survey. 9% (n=30) of respondents have been clinically diagnosed with PCOS and 28% (n=100) of respondents were unawa...

The aim of this study was to quantify and profile the external load of practices and games during a Power-5 DI Women's Collegiate Basketball season. Specifically, Average PlayerLoad (PL), PlayerLoad per minute (PL*min−1), High Inertial Movement Analysis (High-IMA), and Jumps were quantified using Catapult Openfield software during four distinct training periods of the year: 8-hour preseason, 20-hour preseason, non-conference, and conference game play. Weekly variations and acute to chronic workload ratios (ACWR) were also examined. Eleven subjects participated in daily external load monitoring during practice and games via Catapult's ClearSky T6 inertial measurement units (IMU). Averages, standard deviations, and confidence intervals were calculated for training period comparisons, and Cohen's d was calculated as a measure of ...

This study examined packing strategies of Division 1 NCAA female cross-country runners. Packing was defined as any team member running within a second of a teammate at a given checkpoint during the race. All competitors across three women’s races wore chip-timing bibs that recorded each competitor’s time at checkpoints throughout the race. Only teams having five or more runners were included in the analysis. A “packing score %” was calculated for each team by dividing the number of times a runner was within a second of a teammate at a checkpoint in a given interval by the total number of packing opportunities within the interval (PS%). The total scoring team time was then calculated from the finishing time of each team’s top five runners (Team Aggregate Time-...

Current research regarding nutrition among climbers is sparse but suggests that they may be at high risk for low energy availability and Relative Energy Deficiency in Sport (RED-S). The prevalence of amenorrhea, one of the primary indicators of RED-S, is unknown in this athletic population. The purpose of this study was to determine the prevalence of current (previous 12 months) amenorrhea among elite level competitive sport climbers.MethodsAn anonymous online survey was distributed via email to 1,500 female climbers registered as competitors within the International Federation of Sport Climbing to assess the prevalence of amenorrhea over the past 12 months.ResultsA total of 114 female sport climbers answered all survey questions regarding menstrual function and 18 athletes (15.8%) presented with current amenorrhea.
