New supplement and exercise program rejuvenates muscles in older adults

New Muscle Building Supplement: The deterioration of muscle mass and strength that is a normal part of aging -known as sarcopenia—can increase the risk for falls, metabolic disorders and the need for assisted living, say researchers.
“Older people who do little to prevent the progression of sarcopenia drift toward a state where they find activities of daily living, like rising from a chair or ascending stairs very difficult or maybe impossible,” says lead scientist Stuart Phillips, professor in the Department of Kinesiology and member of McMaster’s Institute for Research on Aging.
Results of Study of Older Men Over 70
For the study, which was published today in the journal PLOS ONE, the research team recruited two groups of men aged 70 and older. One group took a protein-based, multi-ingredient nutritional supplement for six weeks without an exercise regimen, while the other group took a placebo. The objective was to evaluate whether daily consumption would result in gains in strength and lean body mass.
Following those six weeks, subjects continued to take the supplement (and placebo) while also undertaking a 12-week progressive exercise training program consisting of resistance and high-intensity interval training. “The results were more impressive than we expected,” says Kirsten Bell, a PhD student who worked on the study.
