Electronic Theses and Dissertations
Beta-alanine is a non-essential amino acid that when combined with L-histidine forms the dipeptide carnosine. Recent research has shown that supplementary intake of beta-alanine can substantially increase carnosine content in muscle fibers and has been associated with attenuating fatigue and enhancing high intensity exercise performance. The aim of this study was to examine the effects of 4 weeks of beta-alanine supplementation combined with high intensity interval training (HIIT) on indices of aerobic and anaerobic performance, rowing performance, and body composition. Twenty-one recreationally active females (22.2 ± 2.2 yrs.) participated in a double blind, placebo controlled study and were randomly assigned …

Female Natural Bodybuilding Competition Preparation: A 6-Week Case Study, Samantha G. Gwazdauskas
Electronic Theses and Dissertations
Bodybuilding is unlike any other sport. Competitors are judged on appearance rather than performance, where muscle size and definition are keys to achieving success. This case study tracked four, drug-free, female bodybuilders for 6-weeks leading up to their competitions. The purpose of this project was to examine the physiological and psychological experiences of female bodybuilders as they prepare for competition. Each competitor reported for testing at three occasions to evaluate cardiovascular measures, body composition, resting metabolic rate, performance measures of strength, power, muscular endurance, and maximal oxygen consumption, mood state, social physique anxiety, and overall experience. Each subject in this …
