Influence of Carbohydrate on Amino Acid Absorption From Dietary Protein (ICADP)

10 young males will be recruited to participate in a randomized double blinded crossover study to investigate the influence of concomitant intake of two different types of carbohydrate with protein hydrolysate on the absorption kinetics of protein-derived amino acids and the impact on myofibrillar protein synthesis. During the trial days the subjects will perform a bout of whole body resistance exercise and ingest a supplement of meat hydrolysate labeled with D5-phenylalanine together with randomized and double blinded type of carbohydrate consisting of either glucose or cluster dextrin. The primary outcome is the time to obtain peak concentration of D5-phenylalanine after intake of meat hydrolysate with either glucose or cluster dextrin. Hypotheses: I) The cluster dextrin will increase the absorption of the amino acids from the meat hydrolysate, and thereby result in a faster rise and a higher peak in plasma amino acid concentration in the postprandial period. II) The meat hydrolysate will increase the protein synthesis rate to a higher extent when combined with cluster dextrin than with glucose.
