Purpose: The purpose of this study is to analyze the kinematic characteristics and regression relationship of the lower extremity joints when the landing height increased during landing.
Method: In order to analyze landing motion at 40, 60, 80, and 100 cm landing height, 10 healthy male college students were selected as subjects and analyzed by 3-D cinematography procedure. As the landing height increased, the peak value and the impulse of the vertical ground reaction force increased significantly but did not increase strongly and linearly.
Results: The results of this study are as follows. First, the peak angular and the peak angular velocity of the joints increased significantly in knee and hip joints. In particular, the peak angular velocity of the knee and hip joints showed the strongest regression in relation to the increase of the landing height. 2) The peak negative power and the peak negative work of the joints showed a tendency to increase as the landing height increased, but did not show a strong regression relationship. )3 Analysis of the percentage of negative work of the joints showed that the proportion of the ankle and hip joint increased with the increase of the landing height, but the proportion of the knee joint decreased.
Conclusion: In summary, the increased angular velocity of the knee & hip joints and the increased role of the negative work in the ankle & hip joints are important characteristics to alleviate the impact force when the landing height increased.
