Outline of Final Research Achievements |
The effects of aging and a period of resistance exercise on the "quantity" and "quality" of skeletal muscle in middle-aged and elderly individuals were analyzed. These results were published in international journals. In the same study, the effects of resistance exercise on brain function were also examined. Some positive effects of resistance exercise on cognitive function were observed (unpublished). Furthermore, we published a review article on the effects of various bioactive substances produced by skeletal muscle (myokine) during exercise on brain function. The importance of the functional linkage between skeletal muscle and the brain was suggested.

Academic Significance and Societal Importance of the Research Achievements |
加齢に伴う筋「量」と「質」の低下が、認知機能低下に関連している可能性が示唆された。逆に、脳(中枢)機能亢進をねらいとするには、骨格筋(末梢)の「量」と「質」の向上戦略が有効である可能性が示唆された。筋を標的とする際、レジスタンストレーニングの重要性は言うまでもないが、さらに重要なこととして、「トレーニングの継続」が挙げられる。そのためには、いかに実施者の負担が少なく効果的に骨格筋の「量」と「質」を向上できるかが肝要であり、運動処方と栄養処方を組み合わせるなど、今後の検討が必要であると考えられた。
