This 3 months randomized, double-blind, placebo-controlled supplementation trial tested the hypothesis that nutritional supplementation (32 g) with whey protein, essential amino acids and vitamin D concurrent with regular, controlled physical activity would increase muscle mass (assessed by DXA), strength (assessed by handgrip dynamometer), physical functional (assessed by ADL), quality of life (assessed by SF-36), and decrease the risk of malnutrition (assessed by MNA and IGF-I) and inflammation (assessed by C-reactive protein) in sarcopenic elderly.
