Outline of Final Research Achievements

This study presents an evaluation perspective that takes into account performance variables and lower limb joint kinetic variables at rebound jump in female athletes, and presents the use of the assessment method in practice. The results showed that female athletes, unlike male athletes, showed a significant relationship between jump height and contact time for rebound jump. On the other hand, similarities between female and male athletes in joint kinetic variables showed that negative ankle joint power was most strongly related to the acquisition of rebound jump index, and differences showed that knee joint torque in the eccentric phase was significantly related to the rebound jump index.

Academic Significance and Societal Importance of the Research Achievements

これまでリバウンドジャンプを用いた下肢筋力・パワー発揮能力の評価診断は男性アスリートを対象にパフォーマンス変数と関節力学量を用いて行われていたが、本研究では、女性アスリートを対象に下肢筋力・パワー発揮特性の男性アスリートとの相違点や類似点を加味した評価観点を示した。また、課題1で示した評価観点を用いて下肢筋力・パワー発揮能力の縦断的な評価を加えることで、実践現場で利用できる評価の観点を提示した。本研究から、リバウンドジャンプの下肢筋力・パワー発揮能力の評価診断を幅広い対象者で活用するための評価観点を示すことができ、実践現場で性差を考慮した筋力・パワー発揮能力の評価診断が実施可能になった。
