Strength training and protein supplements may keep seniors on their feet

This study tests whether a combination of resistance-based exercise and nutritional supplements (protein and vitamin D) can improve physical function and reduce the risk of disability in older adults living in rural China. Participants are 60 years or older and show early signs of frailty, mobility decline, or nutritional risk. Over 12 weeks, some groups receive exercise training three times a week, daily supplements, or both, while others get health education or a placebo. The goal is to see if this practical program can help seniors maintain their independence.
