Outline of Final Research Achievements

This study aimed to clarify impact of cycling training on stretch-shortening cycle (SSC) function. A hopping test used to measure jump performance utilizing SSC function and muscle activity in the triceps surae before and after cycling training. No change was observed in jump performance before and after training, but a change was observed in the relationship between jump performance and muscle activity (short-latency stretch reflex activity). These results suggest that cycling training does not reduce SSC function, but change neuromuscular activity during SSC exercise.

Academic Significance and Societal Importance of the Research Achievements

これまで長期間の自転車トレーニングは体力の維持・向上や障害予防の観点から検討されてきたが、本研究では自転車トレーニングがSSC機能にもたらす負の影響を検討した。その結果、自転車トレーニングはSSC運動時の神経筋活動を変化させることを示した。この知見は走動作や跳躍動作を伴う様々なスポーツにとって不可欠であるSSC機能を考慮した自転車トレーニングの開発に貢献するものと考えられる。
