Active clinical trials for "Sarcopenia"

The present study is designed to investigate whether timed protein supplementation will increase skeletal muscle mass in the frail elderly population.

In the present study the investigators aim to determine whether leucine supplementation can augment muscle mass and strength and improve body composition in healthy elderly men

Sarcopenia is defined as a syndrome characterized by decline of skeletal muscle mass and strength or an alteration in physical function. Although some studies showed nutritional supplementation alone might have health benefits for older sarcopenic patients, the results were inconsistent and remain controversial. The objective of this study was to evaluate if a sufficient protein diet including supplements with leucine-enriched whey protein and vitamin D can lead to better improvement than sufficient dietary protein alone in maintaining muscle mass and strength among sarcopenic elders.

This study is being completed for patients with cirrhosis, including patients with a prior history of hepatic encephalopathy (HE) to evaluate the feasibility and benefits of medically-tailored meals as an intervention. Patients will be enrolled from the University of Michigan and will complete the baseline assessments in-person or remotely. In addition participants will complete study related materials before, during and after treatment with medically-tailored meals (MTM). After completing the study meals, participants will return for follow-up or have this visit completed remotely as well as have an observational period for 12 more weeks.

The primary aim of this study is to improve both physical fitness and sarcopenia of patients with ESLD who are potentially eligible for liver transplantation through a 12-week physical training program. Secondary aims will focus on changes in anthropometrics, body composition, quality of life, and metabolic profile. This is a randomized clinical trial including 50 patients, with half allocated to the active group (physical training program) and half to standard of care.

The purpose of this study is to determine how omega-3 fatty acids influence muscle protein metabolism and mitochondrial physiology in the context of human aging.

A critical problem facing aging adults is muscle weakness. Whereas scientists have traditionally attributed the loss of muscle strength with aging to muscle atrophy, emerging evidence suggests that impairments in the neuromuscular system's ability to voluntarily generate force plays a more central role than previously appreciated. One area that has not yet been investigated includes the role that observing another's actions - thereby activating mirror neurons - plays in muscle force generation. Therefore, the purpose of this study is to examine the acute effects of action observation on muscular strength, voluntary muscle activation, and cortical excitability and inhibition in older adults.

Many elderly experience weight loss and weakness with normal aging. Although there is extensive literature regarding nutritional advice for the elderly, there are few well- designed studies evaluating the effect of oral nutrition supplements in patients with weight loss and aging. The aim of this study is to examine the effect of dietary prescription with or without nutrition supplementation that includes soy protein, whey protein and fish oil in elderly patients who have suffered unintentional weight loss.

To assess the impact of a muscle-targeted nutritional therapy consisting of nutritional counseling and high-quality whey protein-based oral nutritional supplements enriched with leucine and vitamin D, on the recovery of post-COVID-19 patients

The objective of this study is to test the effects of a healthy diet & walking (Controls) compared to a healthy diet, walking, and balance/strength exercises (Intervention) on muscle density in two populations: elderly individuals and obese individuals. The intervention will be 3 months in length. During this time, both Control and Intervention groups will meet one time each week for educational sessions on healthy diet strategies and to participate in a group walk for the Control group or group exercises for the Intervention group. The Control group will be asked to walk on their own an additional 4 times per week (5 times total) for at least 10 minutes/day at the start of the study and build to 30 minutes/day by the 3-month time point. The Intervention group will walk two times per week using the same criteria as above, and in addition will do balance/strength exercises on a total of three days per week. Measurements will be made at baseline, at intervention completion (3 months) and at a follow-up (6 months -3 months after completion of the intervention). At 3 months, the control group will be invited to add the balance/strength exercises. The hypotheses are that adding balance & strength exercises to a healthy diet plan will increase muscle density (decrease fat infiltration) and improve muscle function in the elderly and in the obese populations. Increases in muscle density are expected to show greater improvements in muscle function in the elderly population, while it is speculated that greater improvements in metabolic measures will show in the obese population. Participants in the intervention group will have a greater reduction in falls and less hospital, ER & clinic visits compared to the control group, but both groups will have an improved quality of life, positive changes in eating behaviors, and decreased perceived stress.
