Exercise Clinical Trials

The innovative MPBA+F begins with peer-to-peer mentoring followed by structured parental/family support for long-term reinforcement of PA behaviors. Building and reinforcing skills, MPBA+F mitigates resource stressors and strengthens protective factors by providing culturally appropriate knowledge and skills to improve the sustainability of physical activity at home without the use of exercise equipment. By strengthening social support through peer and friendship networks and family-based support, MPBA+F responds to the unique needs of rural Appalachians in a culturally responsive way. This study targets physical activity among children with overweight, obesity, or extreme obesity because rural Appalachian communities identify sedentary activity as a key contributor to the high rates of obesity and diabetes risk among youth.

RESIST PAD is a randomized trial of 200 PAD patients to establish: 1) whether a 12-week exercise intervention significantly increases Δ nitrite at 12-week follow-up, compared to control; 2) whether exercise "responders" have greater Δ nitrite increases compared to "non-responders"; 3) among non-responders, whether supplementing exercise with nitrate-rich beetroot juice between weeks 13-24 increases Δ nitrite and improves 6-minute walk at 24-week follow-up.

This Study aims to build a diverse and inclusive group of participants to help researchers advance our understanding of how signals and information collected from apps and devices relate to health and may be used to predict, detect, monitor, and manage changes in health. Participants will be asked to complete tasks and surveys, using their iPhone and Apple Research app which include: * Selecting the types of data they would like to share with the study such as health and sensor data * Complete tasks and surveys including areas such as personal demographic information, personal medical history, family history, and social determinants of health Read Less

Hispanic Americans are the fastest growing older adult group in the United States, disproportionally increasing the risk of an Alzheimer's disease and related dementias diagnosis. Efforts to reduce this risk and mitigate the related cognitive/physical declines are critical. The aim of this study is to assess the feasibility of enrolling older adults into an aging trajectory cohort, while generating preliminary data on associations of physical and cognitive aging trajectories. Our secondary objective is to generate preliminary data on the association of standard measures of physical activity and physical function with cognitive status. This study fits within our longitudinal research goal to reduce dementia incidence by understanding the mechanisms that drive the cognitive-physical aging trajectory. Read Less

The primary goal of this project is to determine the effects of exercise on the gut microbiome in breast cancer survivors and determine how these changes may relate to psychosocial symptoms such as fatigue. Read Less

The purpose of this study is to determine the feasibility and effects of an adapted Exercising Together, a partnered resistance training program, on the physical and mental health of prostate cancer survivors and their informal caregiver. The Exercising Together program is designed to promote teamwork during supervised group exercise classes delivered remotely through videoconferencing software. The intervention period will be 3-months with a 3-month follow-up. Read Less

The purpose of this study is to test whether a natural product supplement can potentiate the increase in collagen synthesis following the ingestion of collagen protein. The investigators have developed a model of natural (GRAS certified) products that stimulate collagen synthesis, in vitro. The investigators will determine whether the natural product supplement can potentiate the collagen synthetic response to the ingestion of collagen protein. Basal and fed serum will be isolated and these samples will be used to treat human engineered ligaments. Read Less

The gut microbiome refers to the trillions of bacteria that inhabit the stomach and other regions involved in the digestion of food, including the intestines. Compelling studies of animals (rodents) suggest that the health of the gut microbiome may influence skeletal muscle function and exercise performance. To date, there have been no similar observations reported in humans. A common experimental approach in animal studies to temporarily disrupt the gut microbiome is through the use of antibiotic therapies. Azithromycin is an antibiotic medicine prescribed to humans for the treatment of mild to moderate infections caused by bacteria. The purpose of the proposed project is to determine the influence of short-term (5-days) antibiotic therapy (azithromycin) on exercise performance in young, healthy adults. Treadmill exercise performance will be compared in two groups of adults before and after 5-days ingestion of azithromycin, or a placebo (something that has no physical effect). Read Less

The purpose of this randomized controlled trial is to establish the effectiveness of a culturally targeted and individually tailored behavioral intervention to promote maternal glucose metabolism in African American women. Read Less

This study will be a pilot study to evaluate the feasibility, safety and acceptability of Exercise and Liver FITness (EL-FIT), a mHealth exercise training program previously validated in patients with cirrhosis in patients with nonalcoholic steatohepatitis. Read Less

Life in space is completely void of physical and environmental stress. It is well known that living things need regular physical stress (e.g. exercise) to remain strong, functional and healthy. More and more research is showing that regular environmental stress, for example heat and hypoxia, can further improve physical health. Astronauts aboard the international space station (ISS) exercise for 1-2 hours every day to avoid physical deconditioning that would otherwise cause them to age rapidly in space. Although physical exercise is very effective in remedying this deconditioning, today's astronauts still have physiological changes that indicate accelerated aging. This is a cause for concern given NASA's priority to travel to mars within the next decade; a mission that will require at least double the duration in space for our astronauts. The investigators think that the complete absence of environmental stress, i.e., heat, may be contributing to the accelerated aging that occurs during spaceflight. Our study will assess the health effects of adding heat stress to exercise that could be performed in space by astronauts. The goal is to inform best practice for astronauts to avoid physical deconditioning during long-duration spaceflight. This information will also be relevant to life on earth as spaceflight is a model of inactivity here on earth. Therefore, the potential benefits of adding heat stress will likely translate to life in space and on earth. Read Less

This randomized controlled crossover trial of 36 pregnant individuals with gestational diabetes (GDM) or gestational glucose intolerance (GGI) will: 1. Determine the effects of physical activity (PA) timing, specifically 30 minutes of moderate intensity walking or stepping in the morning (between 5am-9am, within 30-40 minutes of starting breakfast), versus late afternoon/evening (between 4pm-8pm, within 30-40 minutes of dinner) on glucose across the 24-hour cycle. 2. Explore the potential effects of the timing of PA on sleep and mood state. Read Less
