The response of skeletal muscle protein synthesis to resistance exercise without nutrition (RE Only) (11) and resistance exercise followed by essential amino acid (RE+EAA) ingestion 1 hour after exercise (9) in young and older adults. Aging is associated with an impaired skeletal muscle protein synthesis response to RE only, however, this impairment is overcome with post exercise nutrient ingesting. Further, nutrient ingestion following resistance exercise produces and additive increase in skeletal muscle protein synthesis in both young and older adults. *Different from basal in respective study, p<0.05, #Different from older in respective study, p<0.05.
