Outline of Final Research Achievements

This study aimed to develop a method for analyzing sprint running behavior using inertial sensors. The method was able to estimate the temporal and posture of running motion using inertial sensors with a certain accuracy, but it was difficult to estimate spatial information accurately, and some compensation was necessary. In the 200m run, the spatial estimation error was larger on the curved running track, suggesting the influence of the trunk's inward leaning motion. In the hurdle run, it is possible that the running speed could be compensated by extracting the hurdling jump motion.

Academic Significance and Societal Importance of the Research Achievements

慣性センサなどの安価で簡便に装着できるウェアラブルセンサのスポーツ現場での活用が期待されている．走動作はあらゆるスポーツにおいて行われる基本的な動作であることからその分析へのニーズは大きい．走動作分析においては，特に速度が高くなるスプリント走において走パラメータの推定が困難となる．加速度の積分を用いた速度・位置の算出においては積分誤差が大きくなることから推定精度を向上させる手法の開発が待たれている．
