Effects of resistance training on strength, function, and muscle mass in older women with sarcopenia

Researchers combined results from earlier studies of older women with sarcopenia, which means age-related loss of muscle and strength. The women took part in resistance training, such as exercises using weights, bands, or their own body weight. Overall, training improved muscle strength and everyday physical function. It also appeared to increase muscle mass, although the size of the benefit varied between studies.

What this means for you: This supports choosing a regular, suitable strength-training program rather than buying a special supplement or device. The best routine and long-term safety remain uncertain because the earlier studies used different exercises and programs.
