Outline of Final Research Achievements |
Physical exercise has been shown to have positive impacts on cognitive function and is expected to be a preventive measure against dementia in older adults. This study aimed to verify the effect of very-light-intensity exercise (37% or less of maximal oxygen intake) on hippocampal memory function in older adults, and to develop a mild exercise program to enhance cognitive function. The results showed that (1) very-light-intensity physical activity has positive effects on hippocampal memory in healthy elderly women, (2) very-light-intensity exercise may rapidly enhance hippocampal memory in older adults, and (3) music and movement tempo that makes people feel energetic and positive is useful to improve cognitive function with mild exercise program.

Academic Significance and Societal Importance of the Research Achievements |
本研究により、ヨガや太極拳のような超低強度運動に相当する軽運動が高齢者の海馬歯状回の機能を改善し、記憶能を高める可能性を支持する結果が得られた。今後、さらに検証を重ねることで超低強度運動の効果とそのメカニズムが明らかになれば、認知症予防を目的とした軽運動プログラムの開発が促進される。さらに、音楽や動きを工夫することで運動の楽しさや気分を高め、認知機能への効果を増大させる効果を明らかにした成果は、運動プログラムの現場実装する上で有用である。
