Putting forth the movement is a power base, with speed as the core, take the good with the speed of the key power for field events, is the only one of throwing event does not use the spin to speed up project, acceleration from cyclical to the cyclical action of conversion of project. The force etelatalo technology is one of the most important functions of, it is the soul in the process of putting forth the with the core, the correct understanding and understand the force to improve the process, putting forth the technology is very important. The project for javelin in the research field of, after they finished the throwing side with the throwing of upper sequence, the force is related to the support of the extremities, Angle motion and brake leg braking force and hair forcibly order form related technical research, all is the domestic many sports scientific research workers are the hot issues. This subject is the purpose of the research significance for our main is men’s javelin throw the athletes to provide the scientific technology reference data; And through the and good men’s javelin throw the technical index parameters athletes contrast, find out the athletes in the technical deficiencies and gap, and search for solutions and the improvement method, make our country men’s javelin throw movement technical level can be improved; This thesis research object is11th national games men’s javelin throw before the final eight athletes, the overall level is higher, and basically represents the men’s javelin throw sports in our country to the highest level, the analysis of kinematics parameter is of some reference value and practical significance for different levels of, can the athletes training provides training guidance.This paper utilizes the literature material law, video analytical method, mathematical statistics method is studied and analyzed, and the force of athletes, body, lower limb phase of each section of speed, Angle statistics and analysis. The results of the study show that,11th national games men’s javelin throw the final eight athletes step in throwing motion of lower limbs stage time change rhythm has three different mode; In the javelin moment of each section of shots body technology parameters change basic same; Javelin moment shots for vertical and horizontal speed speed individual differences; Javelin, initial Angle of attack Angle shot and initial yaw Angle slant generally; In the final stage, brake leg knee shots are gradually spread, and the shots in the instant brake leg knee extend more than the force of the phase Angle of the knee joint Angle biggest; In T1-T2phase of the shoulder axis and hip shaft change each are not identical. At the same time, accelerate distance depends mainly on trying to achieve best effect of many action. Throwing.
