Role Of Satellite Cells In Long Term Fiber Type Shifts, Honglu Liu
Role Of Satellite Cells In Long Term Fiber Type Shifts, Honglu Liu
Lewis Honors College Capstone Collection
Muscle fiber type shifts in respect to satellite cells, muscle stem cells, are not well understood currently. The Peterson Lab has generated a mouse model (PAX7-DTA) that ablates satellite cells to determine if these muscle stem cells contribute to mouse muscle fiber type changes over an eight week period. In the study, control and satellite-cell-ablated mouse groups were split into control and overload groups (via synergist ablation surgery) and placed under similar environmental conditions. Eight weeks post-experiment, muscles were dissected to obtain the plantaris muscles of animals from all groups. Muscle cross-sections obtained were immunohistochemically stained, imaged, quantified by fiber …
Alterations In Visual Processing And Its Impact On Upright Postural Stability In Athletes Following Sport-Related Concussion, Andrea E. Cripps
Alterations In Visual Processing And Its Impact On Upright Postural Stability In Athletes Following Sport-Related Concussion, Andrea E. Cripps
Theses and Dissertations--Rehabilitation Sciences
Athletes are at risk of sustaining a concussion in all sports and at all competitive levels which may lead to balance impairments. Balance results from the integration of visual, vestibular, and somatosensory information. The underlying pathophysiology for balance impairments is not well understood and visuo-motor processing impairments and how these impairments contribute to balance in concussed athletes has not been reported. Objectives: (1) to investigate the influence of visual perturbation on upright postural stability and balance in athletes who have recently suffered a sports-related concussion, (2) to establish the test-retest reliability of a simple visuo-motor processing task. Design: A longitudinal, …
Disordered Eating Habits And Behaviors Among Elite Collegiate Athletes, Ann M. Armes
Disordered Eating Habits And Behaviors Among Elite Collegiate Athletes, Ann M. Armes
Theses and Dissertations--Nutrition and Food Systems
Eating disorders and disordered eating habits and behaviors were measured using the Eating Disorders Inventory-3 Referral Form (EDI-3 RF). The sample consisted of 159 elite, collegiate student athletes, males and females, aged 18 to 22. Five sports were represented, including basketball, gymnastics, soccer, swimming & diving, and volleyball. Overall, findings support the position that athletes, as a distinct population, and specifically female athletes and those that participate in lean sports, are at an increased risk for disordered eating behaviors and diagnosable eating disorders. Of the 159 total athletes that completed the questionnaire, 33% (n=53) of the athletes sampled met one …
Behavioral Intentions And Nonmedical Anabolic Steroid Use Among Non Intercollegiate Athlete Males Ages 18-30, Vitesh Enaker
Behavioral Intentions And Nonmedical Anabolic Steroid Use Among Non Intercollegiate Athlete Males Ages 18-30, Vitesh Enaker
Theses and Dissertations--Kinesiology and Health Promotion
The purpose of this study was to increase understanding of factors associated with nonmedical anabolic steroid use among males ages 18-30 who do not participate in intercollegiate athletics. The Behavioral Intentions and Ergogenic Aid/Performance Enhancer use among non-intercollegiate athlete males survey instrument was developed, reviewed for content validity by a jury of experts, and pilot tested. The pilot testing results (n=25) demonstrated acceptable reliability (Cronbach’s alpha= 0.74). The final version of the Behavioral Intentions and Ergogenic Aid/Performance Enhancer use among non-intercollegiate athlete males survey instrument was administered at two distribution sites which included Ford’s Fitness Center in Lexington, Kentucky and …
