Outline of Final Research Achievements |
The present study examined the combined effects of training and transcranial direct current electricity (tDCS) on bicycle pedaling exercises of varying duration and intensity. In a full-strength pedaling exercise model of approximately 60 seconds, the combination of 5 minutes of relatively high-intensity aerobic training and tDCS significantly increased power in the late phase; in a 10-minute aerobic pedaling exercise model, the combination of 2 weeks of training and anodal tDCS significantly increased pedaling duration significantly prolonged pedaling duration, but there was no significant difference between anodal tDCS and Sham stimulation. These findings suggest that the combined effects of endurance training and tDCS on pedaling exercise are modified by exercise duration and intensity.

Academic Significance and Societal Importance of the Research Achievements |
身体運動のパフォーマンスは、神経、筋、呼吸循環器系機能、トレーニング度等の複雑な組み合わせによって決定される。しかし、神経系機能の中で、運動出力を担う皮質運動野の興奮性がトレーニング効果にどの様な影響を与えるかについては不明な点が多い。本研究では、60秒と約10分のペダリング運動をモデルとしてトレーニングとtDCSの組み合わせ効果を観察した。その結果、400m走を想定した60秒ペダリング運動では、tDCSの効果が見られたが、持久的な10分間のペダリグではその効果は見られなかった。本研究成果は、短時間の激運動時にはトレーニング時の皮質運動野興奮性を高めることが有効であることを示唆する。
