Effects Of Chewing Time On Gastrointestinal Discomfort, Substrate Use, And Performance During Running, Thomas Geaney
Effects Of Chewing Time On Gastrointestinal Discomfort, Substrate Use, And Performance During Running, Thomas Geaney
Human Movement Sciences Theses & Dissertations
Previous research has shown that food particle size affects gastric processing. For example, food particles greater than 3 mm may delay gastric emptying under certain conditions. Delays in gastric emptying can be problematic during aerobic exercise, leading to nausea, bloating, fullness, and other gastrointestinal (GI) symptoms. In some cases, symptoms can be severe enough to negatively affect athletic performance. This study investigated the effects of manipulating chewing duration of carbohydrate sports bars on GI discomfort, physiological responses, and performance during endurance running. This crossover study recruited 12 male runners (age: 36.4 ± 7.2 years, VO2peak: 57.2 ± 4.7 …

Clinicians are focused on ways to preserve function, independence, and quality of life in the aging adult population. Heart disease is the leading cause of death in the U.S.[1]. Thus, assessing the extent of this disease is a high priority in preserving health throughout the lifespan. When determining risk of cardiovascular (CV) disease, functional assessments are recognized as a way to embed function-focused care into assessing disease risk [2]. Ankle-brachial pressure index (ABPI) is a non-invasive reliable predictor for identifying cardiovascular disease risk and mortality [3]. Thus, the purpose was to evaluate the association between functional assessments and ankle brachial …

The Effects Of Fitness Level And Sex On Epoc Following High Intensity Interval And Moderate Intensity Aerobic Exercise, Rachel Lauren Simmons
The Effects Of Fitness Level And Sex On Epoc Following High Intensity Interval And Moderate Intensity Aerobic Exercise, Rachel Lauren Simmons
Human Movement Sciences Theses & Dissertations
In the past few years, much attention has been directed toward shorter-duration vigorous intensity aerobic exercise as opposed to longer-duration moderate intensity exercise. There is conflicting evidence as to whether vigorous exercise can result in a greater excess post-exercise oxygen consumption (EPOC) and thus more calories burned when compared to moderate continuous exercise performed for a longer duration. In addition, the literature contains a dearth of information isolating and investigating male and female response to these exercises, as well as fit and unfit subjects. The purpose of this study was to quantify EPOC following moderate intensity aerobic exercise (MOD) and …
