© 2020 by the authors. Licensee MDPI, Basel, Switzerland. Strategies aiming to promote weight loss usually include anything that results in an increase in energy expenditure (exercise) or a decrease in energy intake (diet). However, the probability of losing weight is low and the probability of sustained weight loss is even lower. Herein, we bring some questions and suggestions about the topic, with a focus on exercise interventions. Based on the current evidence, we should look at how metabolism changes in response to interventions instead of counting calories, so we can choose more efficient models that can account for the …

Relation Of Flt-1 And Endothelial Function In Women Soon After Delivery: Effect Of Physical Activity And Sedentary Behavior, Chloe W. Caudell
Senior Theses
Adverse pregnancy outcomes (APOs) are believed to be caused by poor placental formation. APOs can be characterized by elevated levels of a circulating Fms-like tyrosine kinase biomarker called Flt-1, produced by the placenta when its blood vessels are shallow or inadequately formed. Flt-1 acts directly on the maternal endothelium to impair vascular function during pregnancy and contributes to maternal features of APOs. This study aimed to evaluate the relation of Flt-1 and endothelial function in women soon after delivery. This study also aimed to evaluate the relation of Flt-1 and physical activity and sedentary behavior in women during and soon …

Use Of A Novel Whole-Body Imaging Approach To Predict Resting Metabolic Rates In Athletes, Nicole Vencil
College of Education and Human Sciences: Dissertations, Theses, and Student Research
Prediction of energy expenditure allows for calculation of appropriate energy requirements, which is especially important for athletes. Resting metabolic rate (RMR) is the greatest contributor to total daily energy expenditure (TDEE) and is typically measured via indirect calorimetry. Indirect calorimetry is not always available, which results in the need for predictive equations. Most predictive equations have been developed with participants resembling the general population and have not been found to be appropriate for athletes, as they may incorrectly predict RMR due to the unique differences of body composition between athletes and the general population. The purpose of the present study …

The Effect Of Physical Activity And S-Equol On Neurogenesis In The Hiv-1 Transgenic Rat, Jeremy M. Lapointe
Senior Theses
The aim of this thesis is to investigate the effect of physical activity and the administration of s-equol on rates of neurogenesis in HIV-1 transgenic rats. HIV-1 is a neurodegenerative disease that leads to the wide range of cognitive impairment described as HAND. Neurogenesis is a newly discovered process that involves the birth of new neurons during our adult life within the dentate gyrus of the hippocampus. Therefore, inducing neurogenesis may be a proper therapeutic that can mitigate some of the cognitive destruction seen as a result of HIV-1 infection. Physical activity has shown to increase the rate of neurogenesis …
