장애인 역도 벤치프레스 동작 시 상지의 운동학적 분석: 현장사례연구

초록

The purpose of this study was to clarify the kinematic differences between before and after use of balanced assistance device in the bench press motion of disabled person. Also, we performed image analysis of three disabled weightlifters' para powerlifting motion using four digital cameras. The following results were obtained from this study. First, the performing time spent on each segments indicated that the time were getting short across the all segments when balanced assistance device was used. Second, vertical velocity of barbell increased after using assistance device. Third, the left and right angles of the wrist, elbow, and shoulder joints decreased in the angular variables, and the right shoulder joint angle appeared to be abduction in E2, but the angle difference between left and right were reduced. Fourth, the barbell angle was close to 0° after use of assistance device for all three athletes. In conclusion, the use of balanced assistance device showed a positive effect on kinematic variables during bench press motion.
