Outline of Final Research Achievements

Meal distribution of protein throughout the day is usually skewed. However, its physiological implications are largely unknown. In this study,we evaluated that the timing-dependent effects of protein intake on skeletal muslce volume, using the two-meal-per-day-feeding model. The protein intake at the early active phase promoted skeletal muscle hypertrophy in mice. Its hypertrophic effect was not observed in Clock mutant mice. These data suggest that protein intake at breakfast could be better for the maintenance of skeletal muscle mass.

Academic Significance and Societal Importance of the Research Achievements

本研究課題の成果は、1日の中でのタンパク質の摂取パターンと骨格筋量の関係を示す基礎的データとなり、今後ヒトの栄養を考える上で基礎的情報となり得る。特に本課題では朝食におけるタンパク質の重要性に着目している点から、若年者に多い朝食欠食を減らすための効果的なエビデンスであると考えられる。一方、高齢者に対しては、老化による歩行機能や運動機能の低下を抑える新たな手段として、タンパク質の摂取タイミングの重要性について説く可能性もみられた。
