Biomechanical Analysis Of Deng Ziwu Shot Put Technique

In the shot put movement to higher level of development in the increasingly fierce competition in the present stage, To further improve the performance, It must be more excellence in technology. At present, Our country university games is better, Shot put level also get rapid development, In order to better will be the athletes' potential, To get better results in the focus. This paper USES the method of documentation Expert interview method?2 d video analytic methods Logical analysis, Of 2012 college students in hunan province games men's shot put first Deng Ziwu the technology of shot put and the structure analysis on biomechanical research, Combined with the mathematical method of backward slide of shot put of Deng Ziwu behavioral essentials of the whole process of dynamic analysis of the power and the speed of each link in rhythm and scientific analysis, using the method of horizontal and vertical contrast, Using the method of horizontal and vertical contrast, Longitudinal comparison Deng Ziwu 2012 years after the 2012 and continue training in relevant technology of backward slide of shot put, On comparing the differences in the process of comprehensive and objective analysis; Lateral aspect of the 2012 Deng Ziwu with relatively good man player in our country of the techniques of guang-fu wang and Jia Peng comparing relevant actions, To analyze Deng Ziwu in this process and close the gap between local or compare the objective analysis. The results showed that:(1) Deng Ziwu 2014 shots to height above 2012, height, throw the shot put out when the height, the greater the degree of far more, This is throwing away 2014 degrees away from far degree is one of the reasons of the year in 2012. (2) Deng Ziwu Angle in 2012 and 2012 are in the best Angle, he has good throwing skill in Angle. (3) Deng Ziwu left leg swing top speed, most of the time is appeared in the right leg actively stretching in this stage, so that cannot achieve good place technology push, his right foot off the ground, legs and ground Angle is too large, the swinging leg vertical velocity is larger, but horizontal differential and smaller, and low center of gravity, thus reducing the speed of the body's centre of gravity and the speed of shot put. (4) Deng Ziwu transition stage and final stage technical connection is relatively good. Suggested by the following ways to improve the technology, Such as:in the usual training should do more practice swing; To improve its last technology, access to the most efficient increase stage of shot put final run distance; Strengthen various to wait long for his left leg strength of physical training, in order to adjust the left leg stretching in the contraction of muscle group was in a concession sex work the problem of insufficient ability; Strengthen three times a week and sages equipment belt (8-10 kg of shot put), to increase the ability of shot put, etc.
