복싱 전진스텝 유무에 따른 원·투 스트레이트 동작의 운동역학적 비교분석

초록/요약

Objective of the present study is to comparatively analyze straight motions by step one-two straight and standing one-two straight. For the present study, 7 amateur boxing athletes were selected. For the video recording, 12 infrared cameras (Eagle-4, USA), and 2 force platform (AMTI, USA) were used to measure ground reaction force. The recorded data was analyzed by Motion analysis 3.6 Program and the findings are as follows; 1. For the time required for each section, a step forward showed a faster time in the difference between a movement in standing and a step. 2. On COM displacement, P1 showed no significant difference in the X-axis, but P2 did a significant difference. 3. There was the difference in angular displacement of step one two straight and one two straight in place, both displayed a clockwise motion of the pelvis before E2. angular velocity and acceleration showed a significant difference between a step and standing. moment displayed a significant difference between a step and a movement in standing. 4. Ground reaction force had other patterns between a step and a movement in standing.
