| Outline of Final Research Achievements |
The objective of this study was to investigate the movement patterns to change of direction in sprinters during a curved path and the underlying cause behind these choices. An analysis of fifteen male sprinters revealed that during the right contact phase, runners generate a large external hip rotation torque, while during the left contact phase, they minimize external hip rotation torque to maintain the inward inclination of the support leg while applying plantar flexion torque to generate centripetal ground reaction force. The study also found that curved-path sprinting is influenced by the athlete's inherent sprinting pattern on a straight line, with the lateral distance between the feet during straight-line sprinting affecting the left-right ratio of inward impulse.

本研究で得られた知見は，曲走路の疾走技術が直走路疾走の動作特性によって異なる可能性を示唆するものである．しかし本研究は，その根底にある直走路疾走における左右接地足の側方距離の要因を明らかにすることには至っていない．今後，直走路疾走における左右接地足の側方距離，すなわち直走路疾走における動作特性の要因を明らかにすることで，競技者の動作特性に応じた曲走路疾走の技術課題を示すことができると期待される．
