An Exploration Of A Sport Club President’S Experience, Megan Lynn Flosdorf

Masters Theses, 2010-2019

This constructivist case study explored how sport club presidents at an institution describe their experience. Eleven sport club presidents, five females and six males, participated. They shared their experience through reflective journals and 30 minute semi-structured interviews. Document analysis was conducted for triangulation of the data. Four themes were constructed from the analysis: social competence, vocational competence, practical competence, and involvement. These findings suggest that leadership opportunities within sport club programs, through campus recreation, offer developmental experiences for students. Practical implications are given for sport club professionals and students interested in holding leadership positions.

The Influence Of A Cyp1a2 Polymorphism On The Hemostatic Response To Caffeine, Joseph James Aiello

Masters Theses, 2010-2019

Research has continued to provide conflicting results of caffeine’s effect on acute coronary events; although it is now apparent that a single nucleotide polymorphism at intron 1 of the cytochrome P450 (CYP1A2) gene may explain these equivocal findings. Despite the fact that markers of coagulation potential and fibrinolytic potential are associated with risk for myocardial infarction, the extent to which caffeine affects these markers is unknown. The purposes of this study were to determine the acute effects of caffeine on coagulation and fibrinolytic potential at rest and following maximal exercise and to determine if hemostatic responses engendered by caffeine are …

Muscle Physiology And Performance During Intensified Cycle Training: Impact Of Carbohydrate-Protein Supplementation, Andrew Christian D'Lugos

Masters Theses, 2010-2019

Previous studies show that carbohydrate-protein (CP) ingestion can enhance short-term recovery following exercise, thereby benefiting subsequent exercise performance and compounding physiological parameters, when compared to carbohydrate (CHO) alone. Less is known about the influence that CP supplementation may have over a long-term intervention (several days/weeks). The purpose of this investigation was to determine whether CP supplementation was effective in improving tolerance to a period of intensified training (IT), compared to CHO. Additionally, the influence of CP on recovery/ adaptation to a period of IT followed by a period of reduced volume training (RVT) was examined. Eight endurance-trained cyclists (age: 24.9±7.3 …

Twenty-Four Hour Post-Exercise Hypotension Following Concurrent Cardiovascular And Resistance Exercise, Whitley J. Stone

Masters Theses & Specialist Projects

Despite pharmacological advances, exercise remains a cost effective preventative for cardiovascular disease (CVD) by acutely and chronically lowering systolic blood pressure (SBP). Although numerous studies have investigated aerobic and resistance training’s role in eliciting an acute SBP response termed post-exercise hypotension (PEH), few researchers have investigated how performing both cardiovascular and weight training in a single session (concurrent training) or how different prescriptions for order of exercise modality will elicit this PEH response; no known studies have attempted altering the order of exercise types within each session. This study seeks to determine if the order of exercise type will affect …

These collection measures involve training on the part of the data collector and the participant, are invasive, and themselves elicit some stress. The purpose of this study is to test whether a 10-min repetitive jumping session will cause a significant increase in salivary alpha-amylase, a potential stress biomarker. This study also looks to determine if a 20-min recovery is enough time for amylase levels to return to …

Self Myofascial Release: Effects On Hamstring Range Of Motion And Torque, Dillion F. Evans

Honors Theses

Research has indicated that static stretching may reduce force production capabilities. This has led many practitioners to exchange static stretching for alternative methods of increasing range of motion (ROM) in warm-ups. Despite having little research to support its use, self myofascial release—foam rolling—has been suggested as a viable alternative (Macdonald et al, 2013). The objective of this study was to determine how self myofascial release (SMR) of the hamstring muscle group affects ROM and torque production capabilities of the hamstring muscle group. Ten subjects (age 26.5 6.5 years, mass 74.412.1 kg, height 1738 cm) were recruited. A within subjects randomized, …

Asymmetric Unilateral Transfemoral Prosthetic Simulator, Tyagi Ramakrishnan

USF Tampa Graduate Theses and Dissertations

amputation, which includes reduced force generation at the knee and ankle, reduced control of the leg, and different mass properties relative to their intact leg. The physical change in the prosthetic leg leads to gait asymmetries that include spatial, temporal, or force differences. This altered gait can lead to an increase in energy consumption and pain due to compensating forces and torques. The asymmetric prosthesis demonstrated in this research aims to find a balance between the different types of asymmetries to provide a gait that is more symmetric and to make it overall easier for an amputee to walk.
