136 Clinical Trials for Various Conditions
Aging-related functional declines are thought to be caused by hallmark biological processes that ultimately manifest in physical, mental, and metabolic impairments that compromise healthspan and quality of life. Exercise is a multipotent treatment with promise to mitigate most aging hallmarks, but there is substantial variability in exercisƒe responsiveness. Combining endurance and resistance training in alignment with public health guidelines will be used to better understand variable exercise responsiveness in older adults with the ultimate goal of improving each older adult's capacity to attain the many health benefits of exercise.
This study is being done to understand how chronic inflammation affects muscle function and responses to exercise.
To identify the autonomic effects of recreationally-relevant doses of cannabidiol (CBD) in an older population, and to evaluate the effect of CBD on exercise performance and recovery.
The purpose of this study is to test the effects of an innovative exercise program referred to as movement-2-music (M2M) on health and fitness outcomes in adults with physical/mobility disabilities. One hundred and eight participants with physical/mobility disabilities will be recruited and randomly enrolled into one of two groups: a) M2M or b) waitlist control. The primary aim of this study is to determine the effects of a 12-week M2M program on health and fitness in participants with physical/mobility disabilities who are in one of three functional mobility groups: 1) Group I - only able to exercise while sitting, 2) Group II - able to exercise sitting and standing with/without support, and 3) Group III - able to exercise one side of the body more than the other side. The second aim is to compare the observed effects of the program in this study to a previous M2M study that groups participants based on disability type. The third aim of this study is to test whether adherence (defined as attendance to the 12-week program) affects the effects of M2M in participants with physical/mobility disabilities. The potential influences of different functional mobility and disabilities of participants on how the program affects participants' health and fitness outcomes will also be tested. \*\*In response to COVID-19, the 12-week M2M intervention and all assessments have been modified from being delivered in-person at Lakeshore Foundation to being delivered remotely in real-time through videoconferencing technology.\*\*
Myalgic encephalomyelitis/Chronic fatigue syndrome (ME/CFS), otherwise known as Chronic fatigue syndrome (CFS) or myalgic encephalomyelitis (ME), is an under-recognized disorder whose cause is not yet understood. Suggested theories behind the pathophysiology of this condition include autoimmune causes, an inciting viral illness, and a dysfunctional autonomic nervous system caused by a small fiber polyneuropathy. Symptoms include fatigue, cognitive impairments, gastrointestinal changes, exertional dyspnea, and post-exertional malaise. The latter two symptoms are caused in part by abnormal cardiopulmonary hemodynamics during exercise thought to be due to a small fiber polyneuropathy. This manifests as low biventricular filling pressures throughout exercise seen in patients undergoing an invasive cardiopulmonary exercise test (iCPET) along with small nerve fiber atrophy seen on skin biopsy. After diagnosis, patients are often treated with pyridostigmine (off-label use of this medication) to enhance cholinergic stimulation of norepinephrine release at the post-ganglionic synapse. This is thought to improve venoconstriction at the site of exercising muscles, leading to improved return of blood to the heart and increasing filling of the heart to more appropriate levels during peak exercise. Retrospective studies have shown that noninvasive measurements of exercise capacity, such as oxygen uptake, end-tidal carbon dioxide, and ventilatory efficiency, improve after treatment with pyridostigmine. To date, there are no studies that assess invasive hemodynamics after pyridostigmine administration. It is estimated that four million people suffer from ME/CFS worldwide, a number that is thought to be a gross underestimate of disease prevalence. However, despite its potential for debilitating symptoms, loss of productivity, and worldwide burden, the pathophysiology behind ME/CFS remains unknown and its treatment unclear. By evaluating the exercise response to cholinergic stimulation, this study will shed further light on the link between the autonomic nervous system and cardiopulmonary hemodynamics, potentially leading to new therapeutic targets.
The purpose of this study is to examine the acute effect of continuous and aerobic interval exercise on postexercise central BP response in men with an elevated blood pressure.
This study will examine the effectiveness of two types of group exercise classes on the health and functional status in inactive adults age 18-65 with neurological conditions including Multiple Sclerosis, stroke, and spinal cord injury (SCI). Participants will be randomly assigned to one of three groups; Movement to Music, Adapted Yoga, or a waitlist group who will complete a home-based exercise intervention of either Movement to Music or Adapted Yoga.
Obesity established in adolescence strongly predicts obesity for the remainder of adult life, and the consequences are potentially devastating, characterized by a lifelong burden of co-morbid conditions and depression. This study will provide an exposure to physical activity that is designed to teach and empower sedentary college age individuals to become physically active. The investigators will evaluate whether such exposure can result in lasting changes in exercise behavior and body composition. The study will also provide a better understanding of the genetic factors that influence persistence in an exercise program and that influence whole body response to exercise training. Altering the course of obesity in adolescence has the potential to reduce the adult prevalence of obesity and consequently attenuate the public health burden of overweight and obesity in the investigators population.
The purpose of this study is to determine the effects of consuming an original flavor energy drink on electrocardiographic (ECG) and hemodynamic responses during and after exercise in healthy subjects. The effect of drinking an energy drink on exercise performance will also be evaluated.
Many of the beneficial metabolic effects of endurance exercise training are not due to adaptations to weeks, months, or even years of training, but rather much is due to the response to the most recent exercise session(s). Therefore, the investigators contend that lifestyle interventions for obese individuals should be tailored to optimize the metabolic effects of the most recent exercise session(s). But the "dose" of exercise necessary to evoke these beneficial responses is not known, and the mechanisms responsible for these improvements are poorly understood. The findings from these studies will: 1) establish the minimum "dose" of a single exercise session necessary to improve insulin sensitivity the next day in obese adults, 2) characterize the underlying metabolic factors responsible for the improvement in insulin sensitivity, and 3) assess the cumulative metabolic adaptations that occur over days, weeks, and months of a low-intensity/low-volume lifestyle exercise program. Findings from these studies will provide valuable information for the development of lifestyle programs aimed at maximizing the key metabolic health benefits of each exercise session in obese patients.
The purpose of the study is to evaluate the effects of different amounts and intensities of aerobic exercise training programs, with and without weight loss, in people who are at risk for diabetes. An additional purpose of the study is to evaluate the factors in the blood and in exercising muscles that contribute to the improvement in those risk factors. This information will be used to improve exercise training guidelines for improving cardiovascular and metabolic health in people with abnormal fasting glucose, also known as prediabetes.
This study investigates the degree of improvement in insulin resistance and features of the metabolic syndrome in non-diabetic overweight or obese subjects after training in a low-intensity, moderate-intensity or non-aerobic exercise program, as well as self-initiated exercise behavior after the assigned exercise program.
The PHITE collaborative team, consisting of Tim Broderick, MD (Overall PI), Wright State University (WSU); Marcas Bamman, PhD (Site PI), The University of Alabama at Birmingham (UAB); and Ron Evans, PhD and Joe Ecker, PhD, Salk Institute for Biological Studies, are working with funding from the US Department of Defense (DoD), Office of Naval Research (ONR), to explore the link between physical training and epigenetics. This is a key interest area for the DoD ONR because it provides high-impact optimization of force readiness in warfighters with diverse backgrounds. The term epigenetics refers to heritable changes in gene expression (active versus inactive genes) that does not involve changes to the underlying DNA sequence; a change in phenotype (the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment) without a change in genotype (the genetic constitution of an individual organism) . This in turn affects how cells read the genes. Epigenetic change is a regular and natural occurrence but can also be influenced by several factors including age, the environment/lifestyle, and disease state. Epigenetic modifications can manifest as commonly as the manner in which cells terminally differentiate to end up as skin cells, liver cells, brain cells, etc. New and ongoing research is continuously uncovering the role of epigenetics in a variety of human conditions. This study is designed to assess whether epigenetics is a primary mechanism modulating how individuals adapt to specific exercise training prescriptions designed to produce a warfighter phenotype. The PHITE team is organized around a shared test population of human subjects for which UAB will oversee recruitment, training, testing, and sampling. Healthy but untrained volunteers, both men and women, 18-27 y of age-phenotypical of the US warfighter-will participate in a 12-wk, two-arm, single-blind, randomized, exercise dose-response trial comparing two intensities of combined training: Moderate-Intensity vs. High-Intensity. Biospecimens are collected before and after an acute exercise bout in the pre-training state, and again after 12 weeks of 3 d/wk combined exercise training. Numerous phenotyping assessments are collected before after the 12-week intervention period to associate exercise training outcomes with molecular changes in the skeletal muscle and blood biospecimens.
The goal of this clinical trial is to learn about the processes occurring in the kidneys while under heat stress in healthy volunteers. The main questions it aims to answer are: * How do the chemicals produced by the body change under conditions of higher versus lower heat stress? * What role does a specific area of the body's metabolism, known as NAD+ metabolism, play in the body's response to heat stress, and can this response be modified by taking vitamin B3?
The purpose of the study is to see examine the effects of 3 different levels of physical activity (45 minutes/week, 90 minutes/week, or 150 minutes/week) on arthritis symptoms.
Anxiety disorders are the most common mental health diagnosis in the US; 19.1% of U.S. adults (23.4% for females and 14.3% for males). In addition, the Global Burden of Disease study (2010) found that anxiety disorders were the sixth leading cause of disability (years of life lived with disability). These debilitating disorders are characterized by excessive worry and fear about everyday situations, and physical symptoms including restlessness, being easily fatigued, difficulty concentrating, irritability, muscle tension, or sleep disturbance. Furthermore, anxiety is linked to other mental disorders including depression and substance abuse; is associated with cardiovascular disease risk factors and a higher rate of cardiovascular disease; and is related to premature mortality. These data have led to the investigation of a breadth of plausible treatments for anxiety, including medications and psychotherapy. However, likely due to the breadth of complex mechanisms involved in the pathophysiology of anxiety disorders and the unfavorable side effects of various medications, a considerable number of individuals do not have a satisfactory response to these treatments. This has led investigators to examine plausible novel interventions to alleviate anxiety and its symptoms.
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.
Brain blood flow will be measured during exercise using magnetic resonance imaging.
The objectives of this study are to examine how sex hormones (use of hormonal birth control, menstrual cycle phase) impact glycemic control among women with type 1 diabetes (T1D), and to test adjustments to insulin dosing and food intake to ameliorate cycle-related glycemic variability. A secondary aim is to examine how the menstrual cycle and use of hormonal birth control impact patient-reported outcomes and glycemic responses to physical activity.
The present study aims to address gaps in the literature by evaluating the objectively measured dose-response relationship between exercise and depression symptoms; examining changes in resting (Brain-derived Neurotrophic Factor) BDNF from baseline to week 10 of an exercise intervention; and assessing varying exercise intensities on enjoyment, affect, and health-related quality of life in sedentary young adult college students.
Study Purpose: To examine the acute effects of antioxidant supplementation on energy use during a single bout of exercise in apparently healthy adult men and women. Specifically this study examined the acute effect of MitoQ on: 1. cardiopulmonary responses to submax and maximal exercise 2. Energy expenditure and fat/carbohydrate oxidation during sub maximal exercise. In a double-blind, randomized, placebo controlled, cross-over study design, participants performed 2 experimental trials which differed only in the supplement consumed (MitoQ or Placebo). Participants performed identical exercise protocols which consisted of a series of submaximal workloads followed by a ramp protocol to volitional exhaustion.
The purpose of this research is to determine how exercise affects fat (adipose) tissue and how changes to adipose tissue that occur during and after exercise might improve health in aging and obesity.
The purpose of this pilot study will be to provide i) information on feasibility implementing an exercise intervention trial among patients with cutaneous cancers, including melanoma, squamous cell carcinoma (cuSCC), and Merkel cell carcinoma, scheduled to receive checkpoint blockade immunotherapy, and ii) preliminary data on the impact of a day-of-therapy exercise intervention.
Brain blood flow will be measured during exercise using magnetic resonance imaging.
The purpose of this study is to assess the health and performance outcomes associated with supplementation of Veillonella atypica.
The primary objective of this study is to assess the feasibility of administering the Personalized Single-Category Implicit Association Test (PSC-IAT) to young adult survivors of childhood cancer. Participants will perform a total of three trials of a cognitive task before and after their scheduled SJLIFE cardiovascular stress testing. Participants will then be asked to participate in a qualitative interview about the cognitive task tool and body sensations and emotions experienced during exercise.
This is a pilot feasibility study of an investigation of the influence of excess adiposity on cardiorespiratory fitness (CRF), insulin-like growth factor-1 (IGF-1), and metabolic responses to a standardized aerobic exercise program in cancer survivors. This investigation attempts to isolate the influence of adiposity on these responses. We will enroll overweight, obese, and normal weight cancer survivors with a primary diagnosis of breast, prostate, or colorectal cancer who have completed all cancer-related treatment. Participants will engage in a 15-week aerobic exercise intervention with pre- and post-intervention assessments.
30 minutes of moderate exercise on an arm ergometer, a cycle ergometer, or a treadmill prior to each administration of standard of care checkpoint blockade immunotherapy across all cycles
The purpose of this study is to evaluate the extent to which a single session of light to moderate intensity exercise performed within 30 minutes after receiving either the initial dose of COVID-19 mRNA vaccine may modify the immune response to vaccination, and identify potential underlying mechanisms using gene expression and metabolite analysis. A secondary goal is to establish whether psychosocial factors are associated with immune response to vaccination. Participants will be randomized to either a 90-minute light to moderate intensity exercise session or daily routine as usual (no exercise) after receiving their initial COVID-19 mRNA vaccine. If assigned to exercise, the exercise will begin within 30 minutes after receiving the vaccine and will consist of a brisk walk and/or jog supervised by study personnel. Blood will be collected from participants prior the initial dose, two weeks after the initial dose, one week after the second dose if the individual receive the two-dose vaccine regiment or one month after the initial dose if the individual receives a one-dose vaccine regimen, and three, six, and 12 months following the initial dose. . Side effects will be measured for three days post-vaccination. Antibody and cell-mediated immune response to the vaccine will be measured in blood samples. Gene expression profiles will be analyzed by single cell RNA sequencing. Serum metabolites will be assessed to align with immune measures. Participants will be asked to complete surveys to measure physical activity history, psychosocial stress, resilience, and depression. The hypotheses of this study are: 1) a single session of exercise which take place shortly after receiving either the initial dose or the booster dose of COVID-19 will increase antibody and T cell response to the vaccine and will be associated with differentially expressed genes and an altered metabolite profile, and 2) higher levels of reported stress, and lower levels of resilience will be associated with a reduced antibody and T cell response to the vaccine.
This randomized cross-over study compares two identical cardiorespiratory exercise bouts, differing only in the inclusion or exclusion of a dynamic period of increasing exercise intensity prior to the exercise bout. Planned comparisons include physiological responses and perceived effort during exercise, leukocyte mobilization, and mood between the two exercise sessions.
