Postexercise myofibrillar protein synthesis rates do not differ following 1.5 g essential amino acids compared with 15 and 20 g of whey protein in young females.

ABSTRACT: Optimal adaptation to resistance exercise requires maximal rates of myofibrillar protein synthesis (MyoPS), which can be achieved by postexercise consumption of >20 g of protein or ∼2 g of the essential amino acid (EAA) leucine. These nutritional recommendations are based on studies in males. The aim of the present study was to compare the postexercise MyoPS response to nutrition in young females. Twenty-eight healthy, females [age: 28 ± 8 yr; body mass index (BMI): 24 ± 3 kg/m²] received a primed-continuous infusion of l-[ring-²H₅]-phenylalanine and completed a bout of unilateral resistance exercise before ingesting a drink containing either 1.5 g EAA (n = 10), 15 g (n = 10), or 20 g (n = 8) whey protein, containing 0.6, 1.5, an
