Filter by: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.
Sarcopenia, defined as a reduction in muscle mass and strength, is a major health concern for postmenopausal women. Evidence suggests that lowering inflammation levels is an important strategy to help mitigate age-related muscle dysfunction and loss. In this pilot study, the investigators will study a tocotrienol (vitamin-E isomer) intervention for feasibility and quantify its effects on postmenopausal women with low muscle strength. A double blind, placebo controlled trial will be conducted on fifty-two qualified subjects. The participants will be assigned to placebo or tocotrienols for 24 weeks. All participants will receive an Omron Alvita Optimized Pedometer. The investigators will measure muscular endurance, strength, and size and gut microbiome profiles at 0, 12, and 24 weeks. In addition, the investigators will measure serum and muscle inflammatory levels at 0 and 24 weeks. All data will be analyzed statistically at p<0.05.
Investigate the effect of 12 weeks mixed power training (power and functional exercises) combined with a protein supplementation (30g/d) or not (placebo) on physiological characteristics of muscle and functional capacities in elderly men.
The purpose of this project is to evaluate whether omega-3 fatty acid supplementation (combined eicosapentaenoic acid and docosahexaenoic acid [EPA/DHA] supplement) augments the effects of a 12-week resistance training program in older men. Outcome variables include inflammatory biomarkers in the systemic circulation, body composition and performance measures. The specific inflammatory markers in the blood include: C-reactive protein, tumor necrosis factor-α, interleukin-1β, and interleukin-6. Remaining parameters include: body composition (as assessed by dual energy x-ray absorptiometry), muscle strength (as assessed by chest press and leg press one-repetition maximum strength tests), and functional ability (as assessed by timed up and go test as well as the 6-minute walking test).
The purpose of the trial is to assess the effects of combining regular, generous intakes of high quality protein (primarily from dairy and other animal source proteins) with calorie restriction and low-intensity exercise on muscle quality and muscle adipose infiltration (along with bone mineral density [BMD] and a number of secondary outcomes) in frail, obese, older adults participating in a 6 month intervention. The investigators will compare these effects to those of a traditional control regimen of calorie restriction and low-intensity exercise over the same duration.
