The research uses mechanics ideal model to analyze the world excellent broad-jumper performance and relevant kinematics parameter, finds the mechanical factors that help the broad-jump athletes get the best results, thus provides support for relevant theories of broad-jump teaching and training and provides basis for future broad-jump technology development and training. To build mode for the outstanding broad-jumper performance and the related parameters on the basis of documental materials. Through the related parameters kinematics analysis on athletes long jump performance, it is considered that improving the utilization rate of speed jump is the key to guarantee the takeoff effect and obtain ideal achievement, increasing the utilization of the run-up speed, appropriately increasing vertical speed and increasing the prancing Angle are the important ways for the long jump athletes to achieve best results; Only if the athletes use effective means for targeted training, they can ultimately improve the level of long jump.
