Outline of Final Research Achievements

In this study, we tried to obtain knowledge about the embodiment of tools in kendo, which is a high-speed and complex attack and defense using a Shinai at close range. Kote striking experiments and Kote swinging experiments were conducted on kendo players who were proficient in kendo techniques (proficient group) and kendo players who were equivalent to them (semi-proficient group).As a result, although there was no significant difference in the operating time of the Kote strike and blank swing experiments in each group, it was clarified that (1) the movement distance of the Kensen was longer in the proficient group than in the semi-proficient group, (2) the movement speed of the Kensen was faster, and (3) the movement distance of the left and right hands was shorter. This result supports the hypothesis of the authors that "athletes who are proficient in sports operate large tools with small body movements."

Academic Significance and Societal Importance of the Research Achievements

スポーツ競技に熟練した選手のパフォーマンスは，各競技の特性に応じた合目的性や経済性を兼ね備えていることが分かっているが，本研究では対人競技の中でも至近距離で竹刀を介した高速かつ複雑な攻防を行なう剣道を対象に，競技力と道具の操作能力の関係性について検討を試みた点に，本研究の学術的意義があると言える．本研究の成果は，スポーツの熟練過程やコーチング学の研究領域に新たな発見をもたらすと考える．また，日常生活において，人間は道具を操作する場面に多く遭遇するが，そのような場面で活用可能な有益な情報を提供することにつながる．
