Abstract

The objectives of this dissertation include 1) to review athlete monitoring strategies and the physical performance demands of female soccer match-play and to provide practical application of athlete monitoring programs, 2) to examine individual and group relationship between training load (TL) and subjective recovery and stress state and neuromuscular performance, and 3) to investigate acute effects of match-play on neuromuscular and subjective recovery and stress state in National Collegiate Association Athlete (NCAA) division I collegiate female soccer. TL was assessed using 10Hz Global Navigation Satellite System units. Subjective recovery and stress state was measured using the Short Recovery and Stress Scale (SRSS) consisting of 8 subscales including Physical Performance Capability (PPC) Mental Performance Capability (MPC), Emotional Balance (EB), Overall Recovery (OR), Muscular Stress (MS), Lack of Activation (LA), Negative Emotional State (NES), and Overall Stress (OS). Neuromuscular performance was assessed using countermovement jump (CMJ) with a polyvinyl chloride pipe (CMJ0) and 20kgs bar (CMJ20). CMJ variables included body mass (BdM), jump height (JH), modified reactive strength index (RSI), peak force (PF), relative peak force (RPP), eccentric impulse (EI), concentric impulse (CI), peak power (PP), relative peak power (RPP), eccentric average peak power (EAP), and concentric average power (CAP). Results of this dissertation showed that 12 individual players demonstrated negative correlations between total distance and MPC (p≤0.05, r=-0.78 to -0.34, number of significant individual correlations [N]=3) and OR (p≤0.05, r=-0.91 to -0.08, N=3). Positive correlations were observed between MS and total distance among all individual players (p≤0.05, r=0.21 to 0.82, N=3) while the group correlations were moderate to large (p≤0.001, r=0.55). Results of this dissertation also demonstrated that significant moderate to large decreases were observed at 12 hours post-match in JH, RSI, CI, PP, RPP, and CPA in CMJ0 and CMJ20 (p
