Abstract: Based on mechanics model for reference, ideal for the worlds excellent long jump athletes and the kinematics parameters were analyzed and find the long jump athletes to perform the optimal mechanical factors, thus providing support to the long jump teaching and train related theory, provide the basis for the development and training of long jump technique. Studies have shown that improve the utilization rate of speed when the take off is the guarantee of takeoff effect and the key to obtain ideal result; increasing use of run-up speed, increasing vertical speed, increase leaps Angle is the important way of long jump athletes get good grades; athletes used effective methods with specific training, in order to improve the level of long jump movement finally to achieve.
