Outline of Final Research Achievements	This study found that high-fat diet feeding improves muscle substrate oxidation capacity, and rapid reversal to base line after cessation of high-fat diet feeing in mice. Additionally, we found that low-carbohydrate diet feeding attenuates glucose asorption and glycogen recovery after a bout of exercise in mice.
Academic Significance and Societal Importance of the Research Achievements	摂取する栄養素によって骨格筋をはじめとする各組織がどのような応答を示すかを明らかになることで、脂質などの栄養摂取とスポーツパフォーマンスとの関係性を示すことができた。
