Countermovement Jump Assessment For Monitoring Prolonged Fatigue In Collegiate Female Soccer Players, Jeffrey A. Wilkins Aug 2020

Countermovement Jump Assessment For Monitoring Prolonged Fatigue In Collegiate Female Soccer Players, Jeffrey A. Wilkins

Boise State University Theses and Dissertations

Introduction: Females are 4 to 6 times more likely to sustain an anterior cruciate ligament (ACL) injury than their male counterparts during running and cutting sports, such as soccer. This sex disparity is thought to result from altered lower limb neuromuscular control that females present when fatigued at the end of practice or games. Yet, current fatigue monitoring techniques typically vary in their reliability, applicability and efficiency. Purpose: The purpose of this study is to test the feasibility of the countermovement jump (CMJ) to quickly and reliably monitor fatigue in female soccer athletes. Methods: Twenty-two (age: 19.3 ± 1.1 yrs, …


Sex Effects On Ankle Biomechanics During Sports-Relevant Tasks And Peroneal Muscle Parameters, Wyatt D. Ihmels Aug 2019

Sex Effects On Ankle Biomechanics During Sports-Relevant Tasks And Peroneal Muscle Parameters, Wyatt D. Ihmels

Boise State University Theses and Dissertations

Introduction: Ankle sprains from excessive inversion are the most frequent sports- related injury. Common ankle prophylactics are designed to prevent injury by limiting excessive ankle inversion, yet may restrict other ankle motions leading to repeated re-injury. Females are twice as likely as males to suffer an ankle sprain, however, it is unknown if a sex dimorphism in ankle biomechanics exists when wearing ankle prophylactics, and whether differences in the peroneal musculature exist between sexes. Purpose: To quantify the ability of ankle prophylactics (Ankle Roll Guard (ARG), Brace, Control, and Tape) to prevent excessive ankle inversion during a sudden inversion event, …
