The authors undertook 2 crossover-designed studies to characterize plasma amino acid (AA) responses to the intake of 20 g of protein. In Study 1, 15 untrained and overnight-fasted subjects consumed 20 g protein from skim milk, soy milk, beefsteak, boiled egg, and a liquid meal supplement. In Study 2, 10 fasted endurance-trained subjects consumed 20 g protein from a protein-rich sports bar at rest and after a 60-min submaximal ride. Plasma AA concentrations were measured immediately before and…

The data suggest that whereas separation of CHO and EAA ingestion following exercise may have a transient physiological impact on NBAL, this response is not reflected over a longer period and is unnecessary to optimize post-exercise muscle protein metabolism.

An amino acid and protein (hydrolysate) mixture with a maximal insulinotropic effect when co-ingested with carbohydrate can be applied as a nutritional supplement to strongly elevate insulin concentrations and is positively correlated with plasma leucine, phenylalanine, and tyrosines.

Dietary protein consumed after exercise in excess of the rate at which it can be incorporated into tissue protein stimulates irreversible oxidation, which suggested that the stimulation of MPS after resistance exercise may be related to amino acid availability.

The results indicate that the response of net muscleprotein synthesis to consumption of an EAC solution immediately before resistance exercise is greater than that when the solution is consumed after exercise, primarily because of an increase in muscle protein synthesis as a result of increased delivery of amino acids to the leg.

It is suggested that the availability of amino acids is more important than theavailability of energy for postexercise repair and synthesis of muscle proteins.
