Acute Effects Of Match Play Induced Fatigue On Jump Performance In Collegiate Women's Volleyball, Grayson Flora
Acute Effects Of Match Play Induced Fatigue On Jump Performance In Collegiate Women's Volleyball, Grayson Flora
Electronic Theses and Dissertations
This study investigated changes in maximal jump performance in response to match play induced fatigue. During six sets of tournament match play, seven National Association of Intercollegiate Athletics women’s volleyball athletes accumulated a mean Player Load of 758.6±216.89 au (measured via microsensor accelerometry), and mean session rate of perceived exertion of 1184.1±363.2. Repeated measures ANOVAs were used to identify change with Hedge’s g effect sizes used to assess magnitude of change. Short recovery stress scale results indicated elevated stress (ES=1.401 to 1.588) and decreased recovery (ES = -1.358 to -1.848) 24 hours post-match, trending towards baseline 48 hours post-match. Countermovement …
An Investigation Into The Use Of Biomechanical And Performance Data From Vertical Jump Testing To Monitor Competitive Weightlifters, Dylan Suarez
Electronic Theses and Dissertations
This investigation aimed to employ novel analyses to longitudinal jump testing data gathered from competitive weightlifters to identify how certain biomechanical and performance characteristics obtained from the countermovement jump (CMJ) relate to changes in weightlifting performance over time and if they can differentiate higher and lower performers. A linear mixed-effect model was used to assess and compare the ability of countermovement jump height and net-impulse to predict Sinclair weightlifting total. CMJ force-time waveforms were compared in cross-sectional and repeated measures analyses to distinguish the force application patterns of higher-performing weightlifters and if they change over extended periods of training. It …
Investigating Force-Velocity Profile Alterations And Methodology After Traditional Resistance Training, Joseph D'Amato
Investigating Force-Velocity Profile Alterations And Methodology After Traditional Resistance Training, Joseph D'Amato
Electronic Theses and Dissertations
The purposes of this dissertation were to examine the agreement the agreement between double integration using the trapezoidal method and measurements for push-off distance to create force-velocity profiles, examine the change in push-off distance between loading conditions when force-velocity profiling, and to observe the alterations in mechanical outputs of force-velocity profiles after 15-weeks of off-season training. The major findings are as followed. Using double integration with the trapezoidal method may be a reliable way to estimate push-off distance, despite a small systematic bias. This bias should have negligible effects on push-off distance and therefore not alter or effect calculations in …
2-Day Vs. 4-Day Training Cessation Following A Step Taper In Competitive And Recreational Powerlifters, Benjamin Burke
2-Day Vs. 4-Day Training Cessation Following A Step Taper In Competitive And Recreational Powerlifters, Benjamin Burke
Electronic Theses and Dissertations
The purpose of this study was to compare differences in maximal strength, perceived recovery and stress state, and body composition alterations in powerlifters undergoing a 2-day or 4-day period of training cessation following a step taper. Ten participants completed a 6-week powerlifting specific training protocol. Body composition, perceived recovery and stress state, and maximal strength in the back squat (BS), bench press (BP), and deadlift (DL) were assessed prior to the overreach week (week 5) and either 2-days or 4-days after the taper. Alpha criterion was set at p≤0.05. There were statistically significant increases in BP (pp=0.03) …
