Abstract:

Aging is associated with a loss in muscle mass and a gain in fat mass. These changes are related to a decrease in overall health and functional ability. Advancing sarcopenia is associated with increased risk of fall and fractures, decreased ability to complete activities of daily living, and increase in fatigue, all leading to dependency and disability. This paper examines the effects of several factors, including protein consumption and exercise,that promote optimal muscle protein synthesis with age.
