Porvoo Sarcopenia & Nutrition Trial

This study is testing whether protein supplements combined with simple home exercises can help older adults maintain or build muscle strength. Age-related muscle loss — called sarcopenia — is a common and serious health problem in older people that increases the risk of falls and disability. Researchers in Finland will screen the entire population aged 75 and older in Porvoo to find people who may be losing muscle, then invite them to join the trial.
