골반 회전 유형 차이에 따른 태권도 주춤서 지르기의 분절별 선운동량 및 각운동량 전이 비교 (Comparison of Segmental Linear and Angular Momentum Transfers of the Jireugi in the Taekwondo Juchumseogi Stance for Different Pelvic Rotation)

초록

The purpose of this study was to investigate the differences of the linear and angular momentum transfer in the Taekwondo Juchumseogi stance for different pelvic rotation players in the Jireugi. The motion capture system with sixty-two reflective markers attached on anatomic landmarks of the subject was used for the Jireugi motion data collection in the Taekwondo Juchumseogi stance. Eleven subjects were divided into a pelvis none pre-rotation group and a pelvis pre-rotation group based on their skill.
The three-dimensional linear and angular momentums of the left/right lower extremities, left/right upper extremities, head, pelvis, trunk were used for kinetic chain analysis. Results showed that all players had lager backward/forward linear momentum. Comparison of pre-rotations showed that the pre-rotation group performed higher linear momentum in three components of the left/right lower extremities, head, pelvis, trunk linear momentum, and left upper extremities bending angular momentum than the none pre-rotation group significantly (p<.05). The pre-rotation group showed the tendency to transfer angular momentum gently in the vertical axis rotation in the acceleration phase than the none pre-rotation group.
This information could improve training protocol design for teaching the Jiruegi in the Juchumseogi stance and teaching players, especially beginners, how to make an effective Jireugi.
