Comparing Depression, Anxiety, and Stress in Male vs Female Collegiate Student Athletes during the COVID-19 Pandemic

Looked at the rates of depression, anxiety and stress using the DASS-21 in college athletes during COVID-19. Looked at the difference between males and females over time. Results show there was no significant difference between male and females at PLNU during that time.


Performance Block Prevalence and Contributing Factors in Individualized versus Team Sports

Performance block is a blanket term that research is trying to propose to replace sport specific terms such as yips, mental block, or lost move syndrome. Though symptoms may present slightly different between the sport specific terms, they all have the same core experience of a sudden inability to perform a previously automatic skill. This study compared performance block prevalence between individual and team sports at PLNU and found similar results.


Ball Speed Predictors in One-Legged Attacks in Female Volleyball Players

Previous literature in volleyball biomechanics highlighted jump height and ball speed as key determinants for the success of regular spikes. To further current research and provide athletes and coaches with direct parameters for proper execution of more complex volleyball attacks, ball speed predictors of a slide attack were investigated.


Perception of Depression, Anxiety, and Stress in Student-Athletes Before and After Return to Campus Following COVID-19 Induced Social Isolation

To analyze the mental health status of student-athletes following COVID-19 induced social isolation, perceptions of depression, anxiety, and stress were measured before and after athletes return to campus. Methods: One hundred fourteen NCAA Division II student-athletes took the DASS-21 questionnaire in the Fall semester of 2020 and again in the Spring semester of 2021. Results: Between T1-T2 there were significantly lower scores of depression (p < 0.001) and stress (p < 0.001), but not anxiety (p = 0.107).


Concurrent Validity And Reliability of Mobile Applications In Measuring Vertical Jump Performance

The purpose of this study was to test the concurrent validity and intraclass reliability of two mobile apps designed to measure countermovement jump (CMJ) height. The concurrent validity and reliability of two mobile applications (MyJump2 and What'smyvertical) designed to measure vertical jump heights were analyzed using a force platform and 3D motion analysis as criterion methods.


The Effects of High-Intensity Interval Training versus Moderate-Intensity Continuous Training on Maximal Oxygen Uptake in Sedentary Adults

The purpose of the investigation was to compare the effects of 8 weeks of low-volume high-intensity interval training (HIIT) versus the effects of high-volume moderate-intensity continuous training (MICT) on maximum oxygen uptake (VO2max) in sedentary adults. We hypothesized that increases in VO2max after both interventions would not significantly differ between groups. 24 participants (27.1 ± 8.4 yr, VO2max = 27.7 ± 6.7 ml*kg-1*min-1) completed 4 wk (3 sessions/wk) of MICT (30 min, 70-75% HRmax).
