PROBLEM TO BE SOLVED: To provide a muscle protein synthesis signal activator that activates a muscle protein synthesis signal, a p70S6 kinase phosphorylation promoter that promotes p70S6 kinase phosphorylation, a muscle mass improver or a muscle strength improver that improves a muscle mass or a muscle strength, and a muscle atrophy inhibitor that inhibits muscle atrophy.SOLUTION: The present invention provides a muscle protein synthesis signal activator, a p70S6 kinase phosphorylation promoter, a muscle mass improver, a muscle strength improver, or a muscle atrophy inhibitor comprising at least one tyrosine compound and at least one amino acid selected from the group consisting of leucine and isoleucine, as an active ingredient. |
