Outline of Final Research Achievements

This study aimed to examine whether the ability to produce explosive force at the right timing is related to the ability to land from a jump. The present results demonstrated that participants with increased RFD in the countdown task had a lower loading rate at landing. In other words, the ability to produce explosive force at the right time was related to the ability to absorb the impact loading at landing from a jump.
Considering that sports injuries are strongly associated with the magnitude of the loading rate during landing, the ability to produce explosive force at the right time is crucial to preventing sports injuries. Based on our findings, an increased focus on the ability to produce explosive force at the right time may help reduce the incidence of sports injuries. These results may be helpful when developing an injury prevention program.

Academic Significance and Societal Importance of the Research Achievements

スポーツ傷害が着地衝撃の大きさと強く関係していることを考えると，適切なタイミングで瞬発的な力を発揮する能力は，スポーツ傷害を予防するために非常に重要である。適切なタイミングで瞬発的な力を発揮する能力にさらに重点を置くことが，スポーツ傷害の発生率を減らすのに役立つ可能性があるため，傷害予防プログラムを開発する際に本研究の結果が役立つことが社会的意義と考えている。
