| Abstract: | Through test of the dynamics characteristics of drop jump from different height of the athletes of volleyball, gymnastics and sprint, the result shows that diff erent events has its own speciality in the length of time beating the board, the moment angle before beating the board, the cushioning distance of the center of gravity, the length of time of cushioning, the amplitude of the knee angle from the position of the knew maximum cushioning to the position of maximum stretchi ng etc. However, a general feature has been in the knee angle at the moment of m aximum cushioning, the moment of maximum extending and the rate between the leng th of time of cushioning and extending. Effects coming from the selection of dif ferent drop jump highness have close relationship with the different speciality of athletes and their carrying capacity of lower limbs. |
