Fasting plasma amino acid profiles after resistance exercise with or without nutritional supplementation in older adults: an exploratory analysis of secondary outcomes from a randomized controlled trial

Background

Resistance exercise and nutritional supplementation improve muscle health in older adults, but the metabolic significance of fasting plasma amino acid profiles remains unclear. This study examined changes in fasting plasma amino acid composition over a 12-week intervention period in which community-dwelling older adults underwent resistance exercise with or without protein plus micronutrient supplementation.
