Outline of Final Research Achievements

Effects of drill on improvement of running form was examined. A stride length at the submaximal running speeds was found to increase after the drill. Angles of leg, thigh and shank, and landing distance at landing phase were decreased at maximal running speed after drill, leading the improvement in a running form to make a leg landed just below the center of mass of the body. It is suggested that the drill could be effective to improve a running form.
Ground reaction force and kinematic variables were investigated during running. Ground reaction force of three directions increased with increase in running velocity, but the impulses showed different change depending on the direction. The vertical displacement of the top head was related with step frequency and vertical impulse. These results obtained in this study should be useful for running form improvement.

Academic Significance and Societal Importance of the Research Achievements

市民ランナーにとって、安全で効率の良いランニングフォームを獲得することは重要であるが、市民ランナーが自らそれを学ぶ方法は確立されていない。本研究の目的は、市民ランナーのランニングフォーム学習を支援するシステムを構築することである。身体の真下でのフラットな着地感覚のイメージ作りにより、ブレーキの少ないフォームを獲得できる可能性が示された。頭頂の垂直変位は、ステップ頻度や鉛直方向の力積と関連していた。また、開発したセンサーにより手足の同調を評価できる可能性が示された。
