Interpretive Summary: The interactions between nutritional supplementation and regular participation in exercise training on changes in physical function among older adults remain unclear. The primary objective of this study was to examine the impact of nutritional supplementation plus structured exercise training on 400M walk capacity in mobility-limited older adults across two sites (Boston, USA and Stockholm, Sweden). Older men and women were randomly assigned to a six month long structured exercise program (3 per week) with a daily nutritional supplement (150kcal, 20g whey protein, 800 IU vitamin D) or placebo (30kcal, non-nutritive). Both groups experienced a statistically significant and clinically meaningful improvement in 400 M walk speed. However, there was no difference in 400 M walk improvement between the group that received the nutritional supplement and the group that received the placebo. These results suggest that regular exercise can improve walking speed with no added benefit of nutritional supplementation.

Technical Abstract: Objectives: The interactions between nutritional supplementation and physical activity on changes in physical function among older adults remain unclear. The primary objective of this study was to examine the impact of nutritional supplementation plus structured physical activity on 400M walk capacity in mobility-limited older adults across two sites (Boston, USA and Stockholm, Sweden). Design: All subjects participated in a physical activity program (3x/week for 24 weeks), involving walking, strength, balance, and flexibility exercises. Subjects were randomized to a daily nutritional supplement (150kcal, 20g whey protein, 800 IU vitamin D) or placebo (30kcal, non-nutritive). Setting: Participants were recruited from urban communities at 2 field centers in Boston MA USA and Stockholm SWE. Participants: Mobility-limited (Short Physical Performance Battery (SPPB)
