Outline of Final Research Achievements

The purposes of this research project were 1) to develop inertial measurement unit based simple leg joint flexion strength-power evaluation system, 2) to examine the validity of the system for evaluating joint flexion strength-power, and 3) to investigate the leg joint flexion strength test as an indicator of sprint performance. Through the research project, it was revealed that 1) the hip and knee flexion strength-power variables obtained using the developed system were valid, and 2) the hip and knee flexion strength-power test variables can be considered as indicators of better sprinting performance.

Academic Significance and Societal Importance of the Research Achievements

本研究で開発したシステムにより,これまで簡便に計測することができなかったバリスティックな下肢関節の屈曲力・パワーが計測できるようになり,従来評価が困難であった実践的な下肢関節屈曲筋力・パワー発揮能力の評価が可能となった.また,本研究のシステムはスポーツフィールドにおいて,疾走能力を間接的に評価できることから,さまざまなスポーツ種目におけるトレーニング状況のモニタリングやコンディション評価に生かすことができる.さらに,本研究のシステムを用いた下肢の筋力評価により,従来とは異なる観点から下肢筋力の発達を捉えられる可能性がある.
