Outline of Final Research Achievements

In this research grant project, various types of strength training aimed at improving muscle fatigue resistance were conducted to induce individual differences in training effects on muscle fatigue resistance. By examining these individual differences, I aimed to elucidate the complete mechanism of muscle fatigue. The results suggest that individual variations in muscle architecture influence variances in muscle fatigue resistance during such strength training, although the instances where such individual differences were actually induced were limited.

Academic Significance and Societal Importance of the Research Achievements

日常生活を送る中で,疲労に対する人々の関心は非常に高い.このことは,身体運動を生み出す源である骨格筋についても当てはまる.本研究では,様々な筋力トレーニングを実際に実施することで,筋が疲れにくくなる筋力トレーニングを明らかにすることができた.それ故,本研究は,個々人の筋疲労耐性を加味した上で,人々のQOLやアスリートのコンディションの維持・向上に寄与するような,セミオーダー型の筋力トレーニングプログラムの創出につなげられる可能性を有する.
