| Men's triple jump is the first to enter the world advanced level in China in track and field events. It requires athletes with the condition of high-speed run-up to adapt the complete a set of technical actions. For the completion of the entire action process, any small deviation may lead to the whole jump failure, so it requires that the athletes must have excellent physical quality and higher technical level.Triple jump is once brilliant in our nation, in the early 1960s, Tian Zhao-zhong jump 16.58 meters which is the second in the world. But, from nearly five session of the Olympic Games, medium-small male triple jump final but none with world excellent triple jump, athlete's performance in nearly one meter gap. Thankfully, the 11th national sports in 2009, He Bei province ethlete Li Yan-xi jump 17.59 meters, broke the 15 years of the Asian record, let us see the Chinese triple jump movement development prospects.In view of this, this research through the literature review, the scene photography, video analysis, mathematical statistics method, with the first eight male triple jump athletes in 11th national games as the research object, and put the jump movement which is closely related kinematics parameter as the research content to reveal our elite male triple jump athletes' technical kinematics characteristic. And after parsing the kinematics parameter, compared with overseas elite athletes to find out existing our athletes' unreasonable factors, thus puts forward feasible suggestions to implement optimization training. The results of the study indicate that:(1)Our male triple jump athletes' Tocklai index is smaller,mainly displayed the differences in muscle density and absolute power.(2)Our male triple jump athletes' absolute speed is lower compared with world excellent triple jump athletes, and speed utilization rate is not high. Triple jump results mainly depends on the speed, whether run of practice, all kinds of jumping, strength and technical practice, should pay more attention to speed requirements, we should further improve the utilization rate of speed in future training.(3)Our male triple jump athletes'pedal stretch direction of force master is inaccurate; The support legs concession work ability is poor; Takeoff leg pedal power is shortage, pedal stretched out ability is weak; Weak legs'jump ability is also weak and another questions.(4)Our male triple jump athletes' triple jump proportion and rhythm control ability is bad, always emphasize the first jump distance, neglecting the jump, and the horizontal speed maintain in this step.(5)Our male triple jump athletes should strengthen special strength training on the upper and lower limb, do a large range, swinging speed as training focus.(6)Paying more attention to the entire run-up step,complete technical training,mainly by complete technology to decomposition technique training method helps athletes master jump technique in nature, coherent, complete style.(7)Execute "going out, bringing in" policy. Introduce the foreign advanced training equipment, draws the overseas elite triple jump coaches'experience, formulate the training system which conforms to our own athletes. |
