Shaanxi Province Outstanding Hammer Thrower Qi Dakai-second Session To Prepare For The Games------Analysis Of Technical Diagnostics From Comparison With Competitors And Themselves

In this paper, through the use of speed cameras CASIO America, for2012Kunshan Championships men’s hammer throw of the top five players shooting. Seoul American Levitra use the feedback system to analyze the video recording, according to the technical principles related hammer, biomechanics, sports medicine, etc.The top five players on technical analysis. This paper has selected key indicators hammer technical action by comparison with their competitors and technology indicators, analyze hammer thrower Qi Dakai province hammer technique, its rational analysis and diagnosis, to make theoretical improvement contribution to the level of competitive athletes, Shaanxi Province.The results from the study are as follo wings:Qi Dakai obviously has incoherent phenomenon of rotating rhythm. Demonstrated in terms of speed, the contribution rate of poor pre-swing, rotation speed and strength unreasonable distribution, mainly in the3,4rings rotation. From the time allocation can also be found Qi Dakai during rotation, the ratio of time allocated to a single unreasonable feet on three, four laps total time,and found no more decreased, which is caused by the rotation before reaching declining trend in strength, it is very unreasonable.According to the game data, Qi Dakai own game mode is slower, but also is one of reasons leads to himself did not play the best level.However, the speed of its technical analysis found Qi Dakai explosive advantage is obvious, single and double support ratio is reasonable.In terms of perspective, the main problem is that Qi Dakai in the rotation last lap and the last shot, knee angle, hip angle phenomenon appeared angle is too large, which is appearing in the development process hammer hip extensor stretch phenomenon. This has resulted in reduced radius of rotation, rotation accumulated power loss, and difficult to control the direction of the shot hammer, can easily cause hanging.In terms of sports injuries, hammer thrower mainly knee injury, Qi Dakai is no exception, which is mainly meniscal strain emerged phenomenon, a series of problems such as wear and tear of the patella, the analysis of the main reason is that the ankle strength Qi Dakai, quadriceps strength is weak, which requires their attention and coaches, doctors efforts.
