Outline of Final Research Achievements

This study verified determinants of female sprint acceleration performance in terms of kinematics and physical strength, and developed a training task diagnosis system for improving sprint acceleration ability of female athletes using kinematic and physical strength data, as well as coaches’ suggestions. Through the research project, importance of support hip extension angular velocity and leg extension strength capability as determinants of sprint acceleration performance was revealed. Moreover, integrating obtained data and using machine learning, the training task diagnosis system, which can provide specific tasks of an individual based on her running kinematics and physical strength characteristics, was developed.

Academic Significance and Societal Importance of the Research Achievements

本研究では，女性アスリートを対象に研究を進めたが，女性アスリートを対象としたスポーツ科学研究は世界的に限られている．また，本研究が研究対象とした加速疾走は，陸上競技の短距離走種目に限らず，多くの球技において重要性が指摘されており，本研究の成果は広く応用される可能性がある．一方，本研究では指導者の定性的な評価と動作分析や筋力測定などの定量的評価を融合させ，トレーニング課題提案システムを構築した．このような研究は世界的に行われておらず，スポーツ科学界で指摘されることが多い指導者と研究者の「bridge the gap」を実現する同様の研究のさきがけとなる．
