The Characteristics Of The Rotating Action Of Yan Weibin's Li Weibin Discus Team Athletes

In recent years,Li Weibin coach led the discus throwing players in Yantai city,He has made excellent results in the national competition,One of the teammates is Feng Bin,her technology to a certain extent,represents the Li Weibing The Characteristics of Rotary Movements of Discus Athletes.In this study,we use the literature data method,the sports scene shooting method,the mathematical statistics method and the comparative analysis method to analyze the rotation technology of his discus athlete Feng Bin,we find the characteristics of the technical action,so as to realize the more comprehensive and objective understanding of its rotation Technology,and by comparing the domestic excellent athletes,to find its technology to further optimize the issues that should be noted.The results of Feng Bin show that(1)Rotation acceleration technology belongs to the post-speed type,and its complete technology is also different from the world level.The ratio of rotation in different stages reflects the reasonable rhythm of action technology.(2)The "human-cake" system shows a good acceleration trend in the first two stages of the rotation process.Due to the complexity and difficult control of the overall change of the "human-cake" system in the vacated and transitional stages,the velocity curve Showing a downward trend,the middle of the center of gravity short acceleration and deceleration and discus speed changes do not cooperate,resulting in discs accelerated delay.(3)on the basis of high-speed rotation,so that a good body center of gravity displacement distance,while the body center of gravity height change is not to ensure a smooth movement of the body.(4)different technical aspects of the shoulder and hip axis of the twist angle and the formation of the throw arm and shoulder angle formed by the pull angle data,reflecting her physical and equipment on the good control of the state.Through the analysis of the technology of Feng Bin,we can see the characteristics of the rotation of Li Weibin discus athletes,and it can help other athletes to analyze and diagnose their own technology in their technical style,and to improve their technology level.
