Energy Compensation With Exercise Is Not Dependent On Dose, H. Michael Hays

Theses and Dissertations--Nutrition and Food Systems

Background: Exercise induced weight loss is often less than expected due to a coordinated set of compensatory mechanisms that serve to maintain energy homeostasis. The extent to which exercise frequency, duration, intensity and exercise energy expenditure (ExEE) influences the compensatory response to an exercise-induced energy deficit (energy compensation) is controversial. Determining how these variables impact energy compensation would help health care providers prescribe exercise with greater probability of creating a sustained negative energy balance and subsequent weight loss.

Methods: 44 Overweight/obese men and women (BMI=25-35kg/m²) aged 18 to 40 years were randomized to perform aerobic exercise 2 or 6 days/week …

The Impact Of Exercise In Spaceflight And Microgravity Environments, William Bybee

Mahurin Honors College Capstone Experience/Thesis Projects

Since mankind’s first spaceflight, a significant barricade in reaching distant planets has been the damaging effects of microgravity upon the human body. Effects range from loss in bone mineral density and severe muscle atrophy to autoimmune disorders. The most effective countermeasure of these effects to date is exercise. Implementation of exercise in microgravity is not an easy task, so various specialized equipment must be utilized to effectively administer it. Even with this equipment, exercise as it is currently used does not entirely prevent body systems from undergoing detrimental changes. New modalities and implementations are currently being investigated that may significantly …

Mahurin Honors College Capstone Experience/Thesis Projects

Heart failure (HF) is a complex syndrome with high mortality rates around the world. HF also has diverse etiology as many things contribute such as hypertension, obesity, coronary artery disease, inflammation, and cardiac arrhythmias. Studies have shown that unloading of a failing heart with a left ventricular assist device (LVAD) can lead to cardiac recovery in a subpopulation of individuals with advanced HF. RNA-sequencing and protein expression analysis of myocardial tissue from HF patients who underwent the LVAD implant and heart transplant indicated that subpopulation of HF patients who responded to LVAD unloading had significantly lower levels of mitochondrial pyruvate …

Vitamin D3 Supplementation And Stress Fractures In High-Risk Collegiate Athletes - A Pilot Study, Kevin Williams, Christian Askew, Christopher Mazoue, Jeffrey Guy, Toni M. Torres-Mcgehee, J Benjamin Jackson Iii

Faculty Publications

INTRODUCTION: Vitamin D is paramount to bone health and little is known about vitamin D's role in the prevention of stress fractures in high-risk athletes. This study consists of a prospective, cross-sectional analysis accompanied by a retrospective review for control comparison of vitamin D3 supplementation in high-risk athletes. Our hypothesis is that supplemental vitamin D3 treatment will decrease the occurrence of stress fractures in high-risk collegiate athletes. MATERIALS AND METHODS: A total of 118 NCAA Division I athletes were recruited from 6 high-risk collegiate teams. Blood draws in August and February established baseline 25(OH)D levels. Subjects with serum 25(OH)D <30 ng/mL were supplemented with 50,000 IU of vitamin D3/week for 8 weeks. Treated subjects were re-tested to ensure serum 25(OH)D levels rose to sufficient status. All enrolled subjects were monitored for the development of stress fractures. A 5-year retrospective chart review of athletes from the same sports teams was conducted to determine the incidence of any reported stress fractures in the past. RESULTS: Prospective: 112 of the 118 enrolled subjects were tested in August. Sixty-one demonstrated vitamin D sufficiency (40.2 ng/mL ±8.28) and 51 were either insufficient or deficient (22.7 ng/mL ±4.89). Of the 118 enrolled subjects, 104 were tested in February. Fifty-six demonstrated vitamin D sufficiency (40.7 ng/mL ±9.47) and 48 were insufficient or deficient (21.6 ng/mL ±5.87). Two stress fractures were diagnosed amongst our cohort of 118 student athletes (1.69%). Retrospective: 34 stress fractures were diagnosed in 453 subjects from 01/2010-05/2015 (7.51%). Amongst our athletic teams, the cross-country team specifically demonstrated a statistically significant decrease in stress fracture incidence (p<0.05). We also found a statistically significant reduction in stress fracture incidence amongst the current overall cohort compared to our retrospective cohort (p<0.05). CONCLUSION: In our population, almost half of the tested athletes proved to be vitamin D deficient. Hypovitaminosis D was prevalent throughout the winter months compared with the summer. With vitamin D3 supplementation, the stress fracture rate in our overall cohort demonstrated a statistically significant decrease from 7.51% to 1.65% (p=0.009).

The Effects Of Acute Bouts Of Aerobic And Resistance Exercise On Neuroplasticity, Michael Shafer

West Chester University Master’s Theses

Neuroplasticity takes place when acquiring new skills, after damage to the nervous system, and as a result of sensory deprivation (5). It can also take place due to exercise (11)(22). Few studies exist that look at the effects of anaerobic/resistance training and its effects on Neuroplasticity in humans, as the majority of research found delves into how resistance training can help at the subcortical and spinal level of the body, not in the brain (1). The aim of this study was to determine whether resistance training is as effective as aerobic training at improving neuroplasticity. Five competitive Weightlifters (3 females, …

Emphasizing Task-Specific Hypertrophy To Enhance Sequential Strength And Power Performance, S. Kyle Travis, Ai Ishida, Christopher B. Taber, Andrew C. Fry, Michael Henry Stone

Exercise Science Faculty Publications

While strength is indeed a skill, most discussions have primarily considered structural adaptations rather than ultrastructural augmentation to improve performance. Altering the structural component of the muscle is often the aim of hypertrophic training, yet not all hypertrophy is equal; such alterations are dependent upon how the muscle adapts to the training stimuli and overall training stress. When comparing bodybuilders to strength and power athletes such as powerlifters, weightlifters, and throwers, while muscle size may be similar, the ability to produce force and power is often inequivalent. Thus, performance differences go beyond structural changes and may be due to the …
