Kinematics Analysis Of Characteristics In Each Jump Speed Changes At This Stage Three Men Jump Athletes To Me

Track and field sports is the most number of MEDALS, in the area of competitive sports level of government attaches great importance to one of the strongest projects, no matter in the field of international and domestic competitive sports, all as on behalf of the country or region important observation points of the development of undertakings of physical culture and sports, triple jump movement is an important component project, track and field sports in the development of our country athletics plays an extremely important role and its technical characteristics is more complicated and the requirements for speed and power is very high, belongs to the multistage "jump" sports, technology process is through closely with high-speed run-up and jump three times to complete a series of technical action, in the process of the completion of the whole technical movement, any technology link mistakes could lead to a result is not ideal, or completely failure, so it is a physical quality and technical level of athletes demanding a sport.Triple jump triple jump in the horizontal velocity variation characteristics reflected the present situation of the movement of athletes, the study mainly adopts the literature material method, interview method, experimental testing method, mathematical statistics and comparative analysis method, the object is the 2014 national indoor track and field championships(Beijing sports university) before eight outstanding athletes, from the physical form, quality status, technical characteristics, etc, covering the many factors that result in the change of horizontal velocity, which involves the kinematic parameters include several important Angle, instant speed, average speed of each section of content, from the degree of influence factors and the speed of change, relationship and athletes on these factors show the different characteristics of the contrast and analysis, a more detailed analysis of data, relatively accurate research results, and according to the result of the objective description of men’s triple jump technology present situation in our country, and strive to put forward the rational trend of technological development from theory Angle and the corresponding advice, the horizontal velocity characteristics in triple jump triple jump reflects the current condition of the movement of athletes, from the Angle of the present status of the outstanding master the techniques of triple jump athlete to in-depth and meticulous research and data analysis, relatively accurate research results, and according to the result of the objective description of men’s triple jump technology present situation in our country, and strive to put forward the rational trend of technological development from theory Angle and the corresponding advice, for our country men’s triple jump is a reference for the long-term development of the theory and practice.Through research we found that China’s elite male triple jump athletes can create good step last four levels run-up speed run and jump at the same time also can make a good link up, but the hop stage, some athletes are deliberately leg board enough technical defects, causes loss of horizontal velocity is too large, the result is not ideal, and overall in the triple jump athletes in our country to maintain aspects of horizontal velocity in bottom level state, the loss rate of speed is larger, there are the reasons for this phenomenon is the part in the process of triple jump athletes can’t good to maintain the stability of the body, to move a greater distance.
