Attenuating The Side Effects Of Caloric Restriction Through Exercise And Increased Protein Intake, Jay A. Petersen Jul 2017

Attenuating The Side Effects Of Caloric Restriction Through Exercise And Increased Protein Intake, Jay A. Petersen

Department of Nutrition and Health Sciences: Dissertations, Theses, and Student Research

The effects of caloric restriction (CR) on weight loss and health outcomes are documented, but few controlled studies have addressed its effect on performance. Fat free mass (FFM) is reduced during CR, which may impair performance. The purpose of this thesis was to explore the capacity of these strategies to attenuate the side-effects of calorie-restricted weight loss: Exercise, which preserves FFM during CR, may be employed to maintain performance in an energy-deficient state, and a high protein intake may work in combination with exercise to further protect FFM and performance. Two studies were utilized to address this purpose. In study …


Examination Of The Monoamine Oxidase A Gene Promoter On Motivation To Exercise And Levels Of Voluntary Physical Activity, Erin M. Kinney Jun 2017

Examination Of The Monoamine Oxidase A Gene Promoter On Motivation To Exercise And Levels Of Voluntary Physical Activity, Erin M. Kinney

Senior Theses

Purpose: The purpose of this study was to examine the genetic basis underlying voluntary exercise. Monoamine oxidase A (MAO-A) is an enzyme that acts on monoamine neurotransmitters, such as dopamine, to cause inactivation. There are several polymorphisms in the promoter region of the MAO-A gene, and these variations change transcriptional activity and the amount of MAO-A produced, leading to alterations in available dopamine levels. Interestingly, polymorphisms in MAO-A have been associated recently with physical activity level. This study sought to determine whether there is an association between motivation to exercise, levels of voluntary physical activity, and MAO-A gene polymorphisms.

Methods: …

Exercise To The Rescue: An Analysis Of Altered Metabolic Gene Regulation Post-Exercise In Lean And Obese Individuals, Brandon Mudd

Mahurin Honors College Capstone Experience/Thesis Projects

The skeletal muscle of obese individuals exhibits a depressed ability to metabolize fats. Exercise training is thought to rescue this dampened ability to metabolize fats; mediated by a coordinated increase in the expression of a network of genes that regulate metabolism and fuel utilization. The purpose of this study is to determine the exercise-induced regulation of metabolically important genes in lean and obese individuals. Muscle biopsies (one pre-exercise/baseline and one immediately post-exercise) were obtained from 4 lean (BF% 24.4 ± 5.5; 23.5 yrs ± 1.9) and 13 obese (BF% 39.7 ± 2.4; 26.1 yrs ± 2.3), age-matched, relatively young subjects, …

Exertional Rhabdomyolysis In A 21-Year-Old, Healthy Female After Performing Three Sets Of The Biceps Curl Exercise To Failure With 30% 1rm: A Case Report, Noelle M. Yeo, Brianna D. Mckay, Amelia A. Miramonti, Nathaniel D. M. Jenkins, Joel T. Cramer

UCARE: Research Products

Background: The optimal resistance training program to elicit muscle hypertrophy has been consistently debated and researched. Although 3 sets of 10 repetitions at 70-80% of the 1-repetition maximum (1RM) is widely recommended, recent studies have shown that low-load (~30% 1RM), high-repetition (3 sets of 30-40 repetitions) resistance training can elicit similar muscular hypertrophy. Therefore, this type of resistance training has gained popularity, perhaps because less weight is lifted for a longer duration. In the process of testing this hypothesis in a research study in our laboratory, a subject diagnosed with exertional rhabdomyolysis after completing a single resistance training session …

Vascular Regulation Via Kir Channels And Na+ /K+-Atpase, Anne R. Crecelius, Frank A. Dinenno

Health and Sport Science Faculty Publications

Despite the longstanding knowledge that blood flow increases in proportion to metabolic activity of skeletal muscle, the underlying mechanisms that govern this response have only recently been identified.1 Given the role of endothelial cells in mediating exercise hyperemia,2 interest has been focused on endothelium-derived vasodilation occurring via the synthesis of nitric oxide (NO) and vasodilating prostaglandins (PGs; i.e. prostacyclin) or endothelium- derived hyperpolarization. A number of studies performed in humans have established a minimal-to-modest role for NO and PGs during mild- and moderate- intensity exercise. In animal preparations, prevention of hyperpolarization attenuates contraction-induced hyperemia; however, performing similar studies …
