349 Clinical Trials for Various Conditions
The goal of this clinical trial is to evaluate how different exercise programs alter bone density, structure, and strength in adults. It will also collect data on hormones, factors released from skeletal muscle, and body composition. The main questions it aims to answer are: * Do exercise programs that are frequent with high-impact loading will cause greater improvements in bone health? * What changes in hormones, factors released from skeletal muscle, and body composition contribute to bone adaptations? Researchers will compare different exercise groups to see if the type of exercise influences bone adaptation compared to a recreationally active control group. Participants are asked to: * complete questionnaires, 5 blood draws across the study (3 at rest, 2 after strenuous exercise), dual energy x-ray absorptiometry (DXA) scans (to assess bone mineral density and body composition), high resolution tibial scans to assess bone structure and geometry, and physical performance testing. * attend up to 7 testing visits. * (for those randomized to the exercise training intervention) participate in exercise training sessions for 6 months.
Exercise, Healthy
The overall objective of this project is to advance understanding of the causes of normal weight obesity (NWO) in men, namely the hormone profile and related potential mediating mechanisms, and the efficacy of different modes of exercise to restore body composition and cardiometabolic health in this population.
Normal-weight Obesity
This study will utilize University of Michigan EMR data to form a retrospective cohort of severe asthma patients on biologic therapies for asthma with computed tomography (CT) imaging and known outcomes on therapy. These images will then be analyzed using morphomics, a combination of high-throughput image analysis and deep learning techniques, to derive imaging biomarkers that will be able to predict therapeutic response to biologics. These biomarkers will then be tested in a second cohort from the National Jewish Health to assess for validity.
Asthma
This is a pilot research study to investigate the effects of a probiotic supplement (L. acidophilus, strain TW01) on substances found in the stool and bloodstream, gut bacteria composition, body composition, as well as any relationship of these substances with markers of inflammation. Lactobacillus acidophilus is commonly found in a variety of fermented foods, including yogurt, cheese, and kefir, due to its ability to produce lactic acid and other substances. This bacterium is generally well-tolerated in healthy individuals and has a longstanding history of safe use. The investigators are doing this pilot study to see if a particular probiotic, called L. acidophilus (strain TW01) and isolated from fermented coffee grounds, can make a positive difference in human gut and overall health. Specifically, the investigators want to look at how this probiotic affects certain substances in human stool and blood, the makeup of the bacteria in the gut, and aspects of body composition. The investigators are also interested in whether these changes relate to markers of inflammation, which can tell us more about their impact on overall health. This probiotic strain has been shown in other studies to be safe and well tolerated, and the investigators hope our research will help us better understand how it works and whether it might support health in humans.
Overweight (BMI > 25), Obese, Otherwise Healthy Volunteers
In this study, the investigators hypothesize that a high dose of post-workout protein nutrition regimen focused on food quality and an observed exercise regimen utilizing high-load resistance training initiated during or after cancer treatment will improve body composition and functional capacity.
Cancer, Breast Cancer
Most of the time, body weight is evaluated by looking at the ratio of your weight to your height. This measurement is called body mass index or BMI. However, BMI does not account for what your body is actually made up of (e.g., body fat versus muscle), which may be more important for determining cardiovascular disease risk. The investigators aim to understand vascular health in females with a "healthy" BMI with differing amounts of body fat and muscle mass. We will have participants come to the lab for two different study visits. At one visit, participants will eat a meal high in fat, and at the other visit, participants will undergo a stress task.
Normal-weight Obesity, BMI, Stress
The objective of this study is to recruit 60 healthy moderately overweight subjects to participate in a research study investigating the effects of a specific probiotic strain (Lactobacillus plantarum KABP-51) on measures of psychological mood state, gut microbiome status, stress hormones, and body composition (body fat and muscle mass). Our subjects will be measured 4 times over the course of a 12-week supplementation period - at Baseline, Week 4, Week 8, and Week 12. We will have 2 groups (N=30 per group): * Probiotic Lactobacillus plantarum KABP-51 * Placebo (maltodextrin/corn starch) Subjects will be recruited from local fitness/wellness centers and businesses (e.g. Plymouth Fitness; Planet Fitness; Marathon Sports, etc) using a simple flyer. If volunteers meet the inclusion/exclusion criteria, they will review/sign the Informed Consent Form (ICF) before any Baseline measurements are collected. Participants will meet weekly (via online webinar) for educational sessions on nutrition, exercise, sleep, stress, and related healthy lifestyle topics. This periodic contact is extremely effective for maintaining compliance with the supplementation regimen and reducing dropouts. Our expectation is that this fairly simple 12-week design will show that the KABP-51 probiotic strain can support a variety of psychological benefits such as reduced stress and improved mood; as well as physical benefits such as improved stress hormone exposure and microbiome balance - all of which may lead to improved body composition (lower body fat and improved muscle mass).
Weight Loss, Mood
The goal of this interventional clinical trial is to learn if the supplementation of magnesium can affect body composition in physically active individuals between the ages of 18 and 30. The main question\[s\] it aims to answer \[is/are\]: How does magnesium supplementation affect body composition in physically active individuals? Participants will take a magnesium capsule once daily for 8 weeks, log their food intake into MyFitnessPal 3 days weekly for the 8 weeks, keep their physical activity consistent to their current regimen, and have 1 baseline appointment with 2 follow ups evenly dispersed (mid-point and post-intervention).
Body Composition Changes
The goal of this prospective crossover simulation study is to evaluate the accuracy and usability of a 3D camera weight estimation system during simulated emergency care in adult simulated patients, when used by emergency physicians. The main questions the study aims to answer are: * to evaluate the accuracy of 3D camera weight estimation during simulated emergency care, when compared with standard methods * to evaluate the usability of 3D camera weight estimation during emergency care, when compared with standard methods * to evaluate the inter-user reliability of 3D camera weight estimates Volunteers for simulated patients will be required to have anthropometric measurements, a DXA scan, and 3D camera weight estimates. Physician volunteers will need to participate in simulated emergency scenarios during which weight-based therapy must be administered. There will be no interventions.
Body Weights and Measures, Body Weight in the Overweight and Obese Class - I Population, Weight Estimation, Emergency Drug Dosing
The overall goal of this study is to investigate the impact of increased physical activity during the postpartum period on on weight loss, body composition, energy expenditure, and body image perceptions following pregnancy and childbirth. Specifically, this study utilizes a mixed methods approach including qualitative and quantitative analyses of the physiological and sociological determinants of postpartum women's health and wellness, The primary objective of the proposed project is to assess the impact of a physical activity intervention on postpartum women\'s ability to return to pre-pregnancy body weight, the resumption of normal activity and bodily function, and the improvement of body image. This objective will be achieved via the assessment of quantitative, physiological markers (i.e. physical activity level, body composition, energy expenditure, and hormone levels), as well as qualitative, sociological markers (i.e. self-report and interview data related to body image and bodily recovery) that serve as a measure of a postpartum body that has resumed relatively normal physical function and activity.
Weight Loss, Postpartum, Physical Activity
The goal of this clinical trial is to learn if the supplement ResArgin (a reservatrol-based supplement) works to slow down muscle loss during a period of fat loss. Other related health outcomes such as sleep, mood, and activity will be assessed. The main questions it aims to answer are: Does ResArgin improve muscle loss? Does ResArgin improve sleep quality, activity, mood, and body satisfaction. Researchers will compare ResArgin to a placebo (a look-alike substance that contains no active ingredients) to see if ResArgin works to improve muscle loss and related health outcomes. Participants will: Take ResArgin or the Placebo every day for 3 months Assessment will occur at Baseline, Day 30, Day 60, and Day 90. Participants will complete a daily diary of their mood and health.
Weight Loss
The obesity epidemic presents a growing concern in the United States, affecting more than 42% of adults. This epidemic extends its impact to chronic diseases and escalating healthcare expenses. Its reach has even influenced the military, with more than 20% of Soldiers being classified as obese, based on Body Mass Index ≥30 kg/m2. Current preventative and countermeasures have produced limited success, prompting consideration of pharmacotherapy. Within this context, glucagon-like peptide-1 receptor agonists (GLP-1RAs), such as semaglutide, have emerged as a promising treatment for obesity. Semaglutide can induce significant weight loss, primarily through fat reduction. However, questions persist regarding its effects on lean mass, physical performance, bone structure, and how it influences the underlying metabolic and hormonal milieu. Furthermore, no studies have been completed in military personnel, who must exercise regularly. Therefore, the investigators will conduct a single-center, open-label, observational trial. The trial will consist of a 24-week semaglutide treatment period and a non-treated 52-week follow-up period. We will test the feasibility and potential benefits of semaglutide in military populations, with a focus on understanding how semaglutide influences body composition, physical performance, hormones, and metabolism. This research holds military significance as obesity rates among service members continue to rise, undermining their medical readiness. Ultimately, it is important to understand if GLP-1RAs can provide a viable solution to obesity in military personnel and if there might be an unexpected effect on physical readiness due to the nature of the weight loss. This could cut down on healthcare expenses by reducing the reliance on weight-related initiatives and, consequently, lowering military separations.
Obesity
The primary objective of this study is to assess the effect of enobosarm on total lean mass as measured by DEXA in patients maintained on GLP-1 receptor agonists.
Muscle Loss, Obesity
This research is being done to determine whether acute exercise causes differences in numbers of novel blood factors associated with vascular health in college-aged adults across different physical activity habits. As only \~50% of cardiovascular (CV) events can be explained by traditional CV risk factors such as high blood pressure and high cholesterol, it is anticipated that this research will provide a more comprehensive look into novel risk factors that may better explain CV risk and that may be modifiable through regular physical activity.
Endothelial Dysfunction, Arterial Stiffness
This protocol seeks to analyze patient outcomes of the standard of care, monitored group exercise regimen of high-load resistance training and functional exercises with compound movements under close supervision on individuals who have been treated for cancer.
Cancer
This study aims to identify if the addition of structured nutrition/weight loss counseling to patients at the bariatric clinic can increase the conversion from bariatric clinic to surgical candidacy from (the current) 11% to a goal of 20% by way of tracking their BIA measurements.
Obesity, Morbid
Obesity, namely at body mass index (BMI) levels exceeding 40kg/m2 (class III obesity), is a risk factor for many diseases including osteoarthritis (OA). In arthroplasty, patients in this population frequently present for and are turned away from surgical intervention. Subsequently, efforts are made to decrease BMI through simple weight loss, yet these have been suggested as ineffective and counterproductive. Furthermore, simple weight loss may include muscle mass loss, which is an additional risk factor for surgery. At the University of Iowa Hospitals and Clinics Orthopedics Department, efforts have been made to encourage muscle mass gain and body fat loss over simple weight loss where progress has been tracked through stationary, multi-frequency bioimpedance analysis (BIA). BIA is a readily available technology offered to industry and consumers, and BIA has recently been incorporated into wearable devices. In the UIHC Orthopedics department, a novel clinic aimed at holistically serving the osteoarthritic-class III obese population for controlled and monitored weight loss through BIA. This study, a randomized controlled trial, aims to recruit adult patients with class III obesity presenting to the arthroplasty-obesity clinic. While all patients will receive individual body composition coaching to increase muscle mass and decrease body fat mass, they will be randomized to one of two cohorts: the study group will receive a wearable BIA wristband (InBody BAND 2) and instruction on its use in addition to the standard coaching, and the control group will only receive the standard coaching. This study aims to identify if the use of a wearable BIA wristband aids in the desired body composition changes. In addition, this study aims to quantify the body composition changes exhibited by each cohort. Finally, this study aims to track surgical outcomes for those patients that are indicated for total joint arthroplasty.
Obesity, Knee Osteoarthritis
This protocol seeks to analyze patient outcomes of the standard of care, monitored group exercise regimen of high-load resistance training and functional exercises with compound movements in conjunction with a nutrition regimen focused on food quality under close supervision on women who have been treated for breast cancer.
Breast Cancer
The primary objective of this study is to evaluate the feasibility and acceptability of obtaining repeated measurements of lean muscle mass, physical function, and biological aging in children receiving active cancer therapy. The secondary objective is to evaluate the feasibility of using the D3-creatine dilution method (D3Cr) to measure skeletal muscle mass in children with cancer. Assessments will be collected at diagnosis, once during active treatment, and end of treatment in coordination with routine imaging to monitor changes in study outcomes during active cancer treatment. Key sociodemographic, treatment and health-related factors will be abstracted from the medical record.
Cancer, Malignant Neoplasm
Semaglutide is a medication approved by the US Food and Drug Administration (FDA) as an antihyperglycemic (a drug that reduces glucoses in those with diabetes) and for weight management. This new study will help find out what effects, semaglutide has on people who take the drug and the drug's effect on physical function, body composition, and aging.
Aging, Diabetes Mellitus, Type 2, PreDiabetes, Overweight and Obesity
Sarcopenia, which is the loss of muscle mass and strength or physical function, naturally occurs in aging. In sarcopenic obesity, growth of muscle mass and increments in strength do not parallel weight gain, and places older adults at increased risk of falls, fractures, physical disability, frailty, and mortality from too low muscle strength relative to body size. The goal of the study is to assess body composition and physical function in older adults with obesity.
Body Composition, Physical Function
The goal of this clinical trial is to learn how a group resistance training plan can improve body mobility and strength in female breast cancer patients who have completed their breast cancer treatment. The main questions it aims to answer are: * Is resistance training feasible following breast cancer treatment * Can it improve the body's mobility and strength lost as a result of the breast cancer treatment * can it improve the body's composition (for example muscle mass) * can resistance training increase one's activity level and help prevent weight gain, perhaps, lowering the risk of cancer recurrence. Participants will attend a group resistance training exercise group program, 3-4 times per week, under close supervision with monitoring a participant's ability to safely and effectively complete the program. The exercises include: lunges, squats and dead lifts.
Breast Cancer Female
This study will evalute the effect of a low glycemic load (LGL diet on dysglycemia, insulin requirements, DXA-derived body composition, gastrointestinal symptoms and quality of life measures in adults with cystic fibrosis-related diabetes (CFRD). We will use continuous glucose monitors (CGM) to assess the LGL diet both in a controlled setting (via a meal delivery company) and in free-living conditions.
Cystic Fibrosis, Cystic Fibrosis-related Diabetes, Cystic Fibrosis With Intestinal Manifestations
This study is a 12-week randomized active control trial that is investigating the effects of Carnipure(R) AAS on muscle hypertrophy, body composition, and muscular strength adaptations in healthy men performing a resistance training program.

This study will evaluate the effects of whole vs. nonfat milk consumption on body composition, cardiometabolic disease risk factors, and dietary quality.
Obesity, Diabetes, Cardiovascular Diseases
The purposes of the study are to quantify and compare relationships among acute changes in inflammatory markers and evoked pain sensitivity after a high-fat meal (HFM) challenge, compared to a moderate-fat meal challenge, and explore the influence of body composition on these responses, in individuals with chronic spinal cord injury
Pain, Inflammatory Response
The purpose of this study is to prospectively assess the impact of TIPS creation on muscle mass and physical function in patients with cirrhosis, and to determine whether these changes correlate with improved outcomes in patients awaiting liver transplantation. Retrospective observational studies have shown improvement in muscle mass and body composition in cirrhotic patients undergoing TIPS. The investigators aim to now prospectively study this through a pilot randomized controlled trial tracking patients managed with TIPS creation compared to those managed without TIPS to determine whether these observational findings can be seen in a randomized cohort. The investigators hypothesize that TIPS creation will lead to improved muscle mass, body composition and muscle function within the first 12 months after the procedure compared to a control group without TIPS, and that these changes will improve liver disease outcomes in patients awaiting liver transplantation.
Cirrhosis, Liver, Sarcopenia
