Motivators And Barriers To Health Behaviors In African American Women, Teresa M. Depratt
Motivators And Barriers To Health Behaviors In African American Women, Teresa M. Depratt
Theses and Dissertations
Women who identify as African American are at particularly high risk of developing obesity and associated health concerns such as diabetes, heart disease, and cancers. Eating healthfully and engaging in a minimal amount of physical activity are known to be both preventative and curative. Based on review of research, this study investigated potential constructs of Motivators and Barriers to health-supporting behaviors as they are perceived in African American women. The study also constructed a novel scale, Motivators and Barriers to Health Behaviors (MBHB), which intended to capture some constructs of each domain via two surveys. Also of interest was if …
The Effects Of Obesity And Surgically-Induced Weight Loss On Exercise Ventilation: Influence Of Central Adiposity And Serum Leptin, Jeffrey Herrick
The Effects Of Obesity And Surgically-Induced Weight Loss On Exercise Ventilation: Influence Of Central Adiposity And Serum Leptin, Jeffrey Herrick
Theses and Dissertations
Truncal adiposity impairs ventilation in obese adults by altering normal ventilatory mechanics. Leptin, an inflammatory adipocytokine, is elevated in obesity and has been shown to alter ventilatory responses to exercise. Leptin’s bioavailability appears to be regulated by its soluble receptor (LRe), which is reduced in obesity. Roux-en-Y gastric bypass surgery (RYGBS) is a weight loss intervention that reduces total fat mass and improves several obesity related co-morbidities including pulmonary dysfunction. The purpose of this study was to first evaluate the differences between ventilatory responses to carbon dioxide (VE/VCO2 slope) during progressive treadmill walking in morbidly obese and normal weight females. …
Time Course Of Vascular Function Changes Following An Acute Maximal Exercise Bout In Obese And Normal Weight Males, R. Lee Franco
Time Course Of Vascular Function Changes Following An Acute Maximal Exercise Bout In Obese And Normal Weight Males, R. Lee Franco
Theses and Dissertations
One of the earliest sub-clinical stages associated with atherosclerosis is endothelial dysfunction (ED), which has been shown to predict future cardiovascular events. Chronic exercise is thought to improve endothelium-dependent vasodilation; however, few studies have evaluated the effects of acute exercise on vascular function (VF). Moreover, studies evaluating ED following an exercise training program lack a standardized time frame in which to measure VF. Although most studies require subjects to abstain from exercise for 24 hours prior to any VF measure, no study to date has assessed VF longer than 24 hours after the cessation of exercise. Additionally, no studies have …
