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.

Exercised induced hypoalgesia (EIH) (reduction in pain) after exercise has been studied in the literature, but no comparisons have been made specifically looking at different types of exercise (isometric/dynamic moving through a range of motion with resistance versus isotonic/applying static resistance to a joint not moving) with neck muscle strengthening. This study will explore to see if one form of exercise is superior to the other in providing EIH. Another benefit of exercise is improving proprioception (knowing where our body is in space). Again no specific investigation has been done comparing isometric versus isotonic exercises for neck muscles. Both of these exercises are often prescribed in physical therapy so further understanding the benefits of them can help improve the prescription of exercises for patients. Read Less

This study aims to elucidate the differences in the gut microbiome functional activity and metabolome in adult premenopausal women with distinctive fitness levels and BMIs (with obesity, w/o obesity). The specific aims are as follows: * Aim 1: To examine the effects of acute aerobic exercise at 60-70% heart rate reserve (HRRmax) for 30 minutes bout on changes in the abundance of SCFA-producing bacteria and their functional downstream metabolic activity. * Aim 2: To examine the effects of acute aerobic exercise at 60-70% HRRmax 30-minute bout on changes in GM-released SCFA concentrations in stool and plasmatic metabolome.

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 goal of this study is to compare two types of exercises, isometric exercise (like squats and planks) and aerobic exercise (such as running), to see which one is more effective at improving blood pressure in teenagers aged 13 to 17.5 years. The main question the study aims to answer is: - Do the effects of one session of isometric exercise on the blood pressure of adolescents compare to the effects of one session of aerobic exercise? Adolescents diagnosed with high blood pressure may qualify for this study. Participants will be randomly assigned to either a single session of isometric exercise or a single session of aerobic exercise. * Participants will attend 3 study visits in total. * Study visits should be completed within 4 weeks of enrollment. * At the initial visit, samples (example: blood) will be collected and body measurements will be taken. * Participants will be asked to answer questionnaires (diet, growth, and others) * At visit 2, participants will have their blood pressure measured using a 24 hour blood pressure monitor. * At visit 3, participants will participate in a single session of either aerobic or isometric exercise. They will wear a 24-hour blood pressure monitor immediately after the exercise session. Read Less

This is a study of the effects of acute, exhaustive exercise on pro-resolving and pro-inflammatory responses in healthy, trained and untrained adults. Read Less

Engaging in regular physical activity during midlife is a key lifestyle behavior associated with reduced risk for Alzheimer's disease and related dementias (AD/ADRD). Yet nearly half of midlife adults (48%) do not meet national physical activity guidelines. The purpose of this mechanistic trial is to identify effective goal setting techniques to enhance psychosocial processes of self-regulation for the successful promotion of PA and adherence to national PA guidelines among midlife adults, with the long-term goal of reducing AD/ADRD risk Read Less

This study is a randomized, double-blind, placebo-controlled study of N=20 active men and women. This study to assess the effect of a novel dietary supplement on improving nutrient gaps and the gut microbiome. Read Less

Natriuretic Peptides (NP) are hormones produced by the heart, and they have a wide range of favorable metabolic benefits. Lower levels of these hormones are associated with an increased likelihood of the development of diabetes and poor cardiometabolic health. Obese and Black individuals have \~30% lower levels of NP and are at a greater risk of developing cardiovascular (CV) events as compared to lean and White counterparts. Some people have common genetic variations that cause them to have \~20% lower NP levels. Similar to other low NP populations, these individuals with low NP genotype (i.e., carrying a common genetic variation called rs5068) are at a greater risk of developing cardiometabolic diseases. By understanding the NP response following the exercise challenge and the glucose challenge in individuals with genetically lower NP levels will help us understand how to improve cardiometabolic health in them.

The goal of this clinical trial is to test the effects of 10 weeks of exercise on overall brain health, reduction in blood pressure, and the number of blood vessels in the back of the eyes in patients with hypertension and have a body mass index ≥ 25 kg/m2. The main question\[s\] it aims to answer are: * To test the effect of moderate vs intensive exercise on Brain Care Score outcomes. * To ascertain the differential impact of moderate vs high intensity exercise in reducing hypertension and its downstream effects.

Examining two strategies as potential adjuvant therapies for Duchenne muscular dystrophy (DMD); aerobic exercise training (to induce adaptations in skeletal muscle and improve cardiovascular health) and tadalafil, an FDA-approved vasodilator (to optimize blood flow and muscle perfusion which is impaired and often overlooked in DMD). Target: improved muscle function, vascular health, and DMD treatment. Read Less
