The Analysis Of The Impact Of Run-up Speed And Takeoff Technique On Long Jump Results Of Competitive Athletes

Long jump is one of the oldest sports, which is needed to be performed with theorganic combination of speed and strength etc. Long jump can not only be used toimprove the basic physical quality of speed, coordination, strength, flexibility andbalanced capacity etc., but also be significant to keep a healthy body for human being.The action of jump is consisted of four parts: run-up, takeoff, flight and landing.And the run-up speed and takeoff technique are the key point for achieving the perfectresult, and also the preconditions and important guarantees for achieving satisfiedathletic performance. Run-up speed and takeoff technique have the relationship ofdynamic balance. Thus, the improvement of the results of long jump takes place in theprocess of breaking the old balance and rebuilding a new balance. With thedevelopment of society, increasingly development of science and technology and thecontinually improvement of cognition in-depth of long jump technique for people, theresult of the international long jump is improved year by year. Different cognitions foraction structures of long jump technique show the understanding and cognition fortakeoff technique of people in different stages.The continuous exploration and study for long jump technique are used not onlyto deepen the understanding of long jump technique of people, but also to promote theprocess of its perfection and development and the improvement of the results of longjump. In this paper, some factors of the top eight athletes of China, includingmorphological index, angles of jumping, landing and takeoff in the moment of takeoffand the angle of ankle, knee and hip of the jumping leg in the jumping stage, theOlympic Games, the Asian Games and the National Games in recent ten years. Theresults of exploration for kinematic characteristics about recent takeoff technique oflong jump, and the impact of run-up speed and takeoff technique on long jump resultsof competitive athletes show that the performance gap of long jump between Chineseand foreign man athletes is intended to be enlarged in the international athletic field.Meanwhile, the performances of Chinese men athletes are significantly better indomestic field than that in World Athletics Championships, the current situation ofwhich is analyzed and studied, in order to find out the influence factor and put forward the solutions, being a reference of the development of Chinese men’s longjump.
