고등부 여자 육상 선수의 100 m 크라우칭 스타트동작에 대한 운동학적 분석

The purpose of this study was to analyze the kinematic factors crouching start movement of skilled and unskilled intended for female high school athletes. Conclusions are as follows. First, the total time is of the subjects showed rapid skilled showed a significant difference in P2 (p <.05). Second, horizontal displacement of the COM has showed a skilled moves away, it showed a significant difference in event 3 (p<.05). And showed a move away from the third period both skilled and unskilled, vertical displacement of the COM did not appear to show significant differences or lower is skilled in all the events. Third, horizontal velocity of the COM has showed rapid skilled in any event, event 2, event 3 and event 4 was significantly different from (p<.05). And the vertical velocity of the COM did not show a significant difference. Fourth, the angle of the joint of the right hip joint event 4, and the right knee showed a significant difference in joint events 4 (p<.05). And skilled has been shown to reduce the hip joint angle of the leg is moved relative to unskilled. Taken together, the vertical displacement of unskilled were low in order to improve the crouching start movement during horizontal velocity. And it is moved by the angle of the hip joint of the leg that is less likely to raise more training needed by dragging the thigh toward your chest. And it would require a study using EMG equipment with GRF to see the various kinetic factors.
