A second aim of this study was to determine differences in metabolic measures (VO2, VE, & RER) between the carbohydrate and water performance trials in youth and adults. A third aim was to examine changes ...


Bilateral Deficit: A Comparison Between Upper-Body And Lower-Body Maximal Strength, James Lee Ramsey Jan 2018

Bilateral Deficit: A Comparison Between Upper-Body And Lower-Body Maximal Strength, James Lee Ramsey

Master's Theses and Doctoral Dissertations

Purpose: The study’s primary purpose was to determine if maximal unilateral strength is greater than maximal bilateral strength for the leg press and vertical dumbbell press exercises. The secondary purpose was to determine if blood glucose levels differ between the unilateral and bilateral conditions for the leg press exercise. Methods: Thirty college-aged volunteers reported on two separate occasions, 72 hours apart, for maximal strength testing. Blood glucose was obtained before and after strength testing for the leg press exercise. A paired samples t-test was conducted to determine significance (p < .05). Results: Participants were significantly stronger for the bilateral leg press; however, no significant differences were observed for the vertical dumbbell press exercise. No significant differences were observed in plasma blood glucose for the leg press exercise. Conclusion: Participants did not display a bilateral lateral deficit, which may have been a result of their resistance training prior to the study.

Influence Of Sports Drink Taste Preference On Consumption In Adult Recreational Soccer Players, Kiarash Molavi

Master's Theses and Doctoral Dissertations

Sports drinks provide nutrients that improve athletic performance. This study investigated whether a preference in taste leads to an increased consumption of a sports drink prior to and after an endurance event in athletes. Male amateur soccer players (n=16) first participated in a blind sensory evaluation to determine their taste preference for two (designated as Drink A and Drink B) similarly flavored sports drinks. Subjects were divided into two groups based on their taste preference for either drink. They then participated in 9 soccer matches and were presented with either Drink A, Drink B, or water (3 trials each ...

The Inflammatory Response To Acute Maximal Sprint Exercise, Timothy A. Muth Jan 2010

The Inflammatory Response To Acute Maximal Sprint Exercise, Timothy A. Muth

Master's Theses and Doctoral Dissertations

The purpose of this study was to determine whether acute maximal sprint exercise would elicit an inflammatory response in trained and untrained runners marked by increased systemic immune proteins and byproducts of oxidation, as well as to determine a time course for the presence of these markers. In procedures approved by the Eastern Michigan University College of Health and Human Services Human Subjects Review Board, subjects participated in a total of five study visits consisting of both exercise and blood draws. Blood analysis seems to indicate that there was a secondary tissue injury, which was responsible for the greatest changes ...

Health Impact Of Brief Interventions By A Registered Dietitian During Exercise Sessions In A Phase 2 Cardiac Rehabilitation Setting, Terrie Holewinski

Master's Theses and Doctoral Dissertations

Weight management is integral to cardiovascular risk reduction. However, minimal weight loss is achieved during participation in many cardiac rehabilitation (CR) programs. The objective of the present study was to establish if brief interventions by a registered dietitian (RD) during cardiac rehabilitation sessions improved the health status of patients with cardiovascular disease. An RD provided individualized nutrition counseling, answered nutrition questions, and reviewed weekly progress in a CR program for a four-month period. At baseline and upon completion of 19 CR sessions, nutrition knowledge was assessed using a 38-question test, and body weight was measured. Upon completing CR, patients rated ...
