Outline of Final Research Achievements

In this study, we examined the effects of static stretching used in sports setting. The results showed that 20-seconds of static stretching of triceps surae and hamstrings was commonly used as a part of warm-up routine. However, there were no significant change in stiffness after 20-seconds of static stretching, but range of motion and passive torque increased. These data indicated that 20-seconds static stretching does not affect the stiffness of the muscles.

Academic Significance and Societal Importance of the Research Achievements

スティフネスを低下させることはスポーツにおける筋腱障害予防に重要である．しかし，本研究の結果から，スポーツ現場で利用されている20秒間の静的ストレッチング後にはスティフネスが変化しないことが明らかとなった．20秒間の静的ストレッチングの効果を詳細に検討した研究は本研究が初めてである．今後は，20秒間でスティフネスを低下できるストレッチング方法の開発が望まれる．
