Outline of Final Research Achievements

With the advancement of GPS systems, wearable devices have become available for indoor use. We used these devices to measure the movements of basketball and handball players during games. As a result, we identified characteristic tendencies in the lower-performing group. This trend was particularly prominent in men's handball. By analyzing when and under what circumstances the measurements were taken, in combination with video data, we found that these tendencies were observed during defensive phases. The combined analysis of wearable device measurements and video data revealed the potential to identify differences in movement between players of varying skill levels, contributing to the development of more efficient coaching methods.

Academic Significance and Societal Importance of the Research Achievements

室内球技競技において下位群の選手に守備局面の場面で特有の動き（この段階で「無駄」な動きと断言できないものの、明らかに上位群とは違う動きが確認できた）が存在することが、ウェラブルデバイスで計測された指標と映像データを合わせて分析することで明らかにすることができた。今後、競技力向上を目指す際のトレーニングオーガナイズや戦術理解、体力強化等、効率的なコーチング方法の開発に貢献できる可能性があることが明らかとなった。
