| Abstract: | It analyzed the loss velocity of run up,the kinematics and kinetic reason of the fast support of take-off and the stretch in the creation mechanism of take-off vertical velocity of long jump with the technical parameters of world elite long jump athletes and the step strength on step phase.It put forward new opinion on the creation of vertical velocity of long jump and provided a new way for innovating long jump training. |
