Sarcopenia
Conditions
Brief summary
This randomized, double-blind, placebo-controlled supplementation trial tested the hypothesis that nutritional supplementation with muscle-target nutritional supplementation concurrent with regular, controlled physical activity would increase the efficacy of physical rehabilitation in old adults suffering from sarcopenia
Detailed description
This randomized, double-blind, placebo-controlled supplementation trial tested the hypothesis that nutritional supplementation with whey protein, essential amino acids - mainly leucine - vitamin D and calcium concurrent with regular, controlled physical activity would increase the efficacy of physical rehabilitation in old adults suffering from sarcopenia
Interventions
Two servings (40 grams each) of powder (Fortifit; Nutricia) which has to be dissolved in 125 ml of water. Per serving, 20 g whey protein, 3 g total leucine, 9 g carbohydrates, 3 g fat, 800 IU vitamin D, and a mixture of vitamins, minerals, and fibers.
Two servings (40 grams each) of an isocaloric (maltodextrins) powder which has to be dissolved in 125 ml of water.
