| Outline of Final Research Achievements |
In this study, the relationship between the brain condition during the pre-set phase before the start of the exercise in drop jump and the performance and the force exertion characteristics of the lower limb joints during the take-off phase was clarified. The results showed that 0.9m was lower than 0.6m in DJ performance, SICI during pre-set phase, and ankle torque during take-off phase. On the other hand, the trend of DJ performance and SICI by each athlete was examined. Some athletes increased and some decreased with the increase of the drop height, but those who increased showed the characteristic of increasing the exertion of the three joints of the lower limbs with the increase of the drop height.

これまでドロップジャンプに関する研究では，踏切局面中の生理学および力学的特性を示した研究がほとんどであるが，本研究では，プレセットという踏切よりもさらに前の局面に着目し，パフォーマンス変数や踏切局面中の下肢関節の力発揮特性を示した．また，本研究の研究成果により，プレセット局面中の脳内状態がドロップジャンプのパフォーマンス変数や踏切局面中の下肢関節の力発揮に影響する可能性が示唆された．したがって，プライオメトリックトレーニングを行う際，プレセット局面に注目して実施するすることで，合目的的にトレーニングを実施できることに繋がる可能性が示された．
