Abstract

This study is to find out effective defensive type by analysis on differences among three different defence types of the body lock technique in the ground wrestling. The subjects are 5 athletes who are in 60kg weight class. To get the kinematic analysis seven ProReflex MCU-240(Motion Capture Unit), infrared rays cameras, which was produced by Qualisys, were used to get a two-dimensional coordinate. Following are the analysis result from kinematic factors such as time element, speed element and angular element. 1. During position of ground wrestling, the average necessary time until defender`s hip joint touches the mat for Phase1 was at side position was the shortest space of time out of three types, and Phase2 was at front position was the shortest space of time out of three types. Moreover, side defence position was the shortest for total average necessary time with . 2. The movement change for hip joint was for front, for rear, and for side at Phase1 and for side, for front, and for rear at Phase2. 3. Movement speed of hip joint at defensive type were most effective in success and fail rate at Phase 1 and its frontal average speed was fastest with following by for side, and for rear. The average for total change of speed is for front, for side, and for rear. 4. The joint angle gets smaller in a order by rear, front, and side for the size of hip joint angle and knee angle for different defensive type. 5. As a result of one-way ANOVA on linear velocity for hip joint in frontal defence(phase1) was significance (
