The major kinematical variables acting upon shooting motion can be described as follows; foot touch point coordination , each shooting movement time, ball velocity angular change of lower limbs segment. The analysis of the above variables presents the following findings: Instep and infront of the ball and the touch foot from the left and right position was significantly different from these of inside. There was stability from the inside position. In terms of the time required for each shooting motion, there was an average of 38.6±18.2 m/sec in TSP stage and 66.8±9.7 m/sec in SSP stage. Maximal velocity showed the mean 24.60±1.45 m/sec. No difference was shown among different types of shooting. Shank segment angle descended toward the minus angle from X direction. However, after knee joint maximal flexion the angle became bigger and before and after the impact, it changed into the plus angle. There was no marked difference between instep and infront at the left foot touch time. At the foot touch time in shank segment angular velocity, instep and infront indicated-227.54±217.36 deg/sec showing the minus rotation and inside showed 46.05±261.59 deg/sec. There shooting in swing leg knee maximal flexion displayed the plus angular velocity and the angular velocity of inside shooting increased significantly compared with other two shooting.
