Analysis Of The Technical Change Characteristics Of Key Pole Vault Players In China From The Perspective Of "Person-Pole" Collaboration

In pole vaulting,the synergy between athletes and pole has been recognized as an important factor affecting performance.However,the characteristics of each athlete’s "man pole" cooperative movement are very different,even in every jump.This paper will try to take the characteristics of "people pole" coordination in pole vaulting as the perspective,collect the data of many events in 2019 of key female pole vaulting athletes in China,sort out the influence of "people pole" coordination effect on sports performance,in order to find the best "people pole" coordination technology of key female pole vaulting athletes in China,and apply it to our Special technical training to promote the stability and improvement of sports performance.Through the methods of literature review,expert interview,video analysis,mathematical statistics and comparative analysis,this paper takes the 2019 competition technology video of the key female pole vault athletes in China,and processes and analyzes the video with the help of the video recording system developed by the sports biomechanics teaching and Research Office of Beijing Sport University Under the condition of horizontal comparison between "pole" technical index data and "man pole" data index of international excellent pole vaulter,this paper makes a vertical comparative analysis on the data index of multiple events of key female pole Vaulters in China.To find out the characteristics of technical changes of key female pole Vaulters in China.The conclusion is as follows: The characteristics of the technical changes of the key female pole Vaulters in the stage of energy acquisition are as follows: the change range of the reverse "short step" take-off is large,the distance of the take-off point and the reduction of the take-off pole shorten are the technical changes of the performance improvement.The characteristics of technical changes of key female pole Vaulters in the energy storage stage are as follows: there are great changes in the technical indexes of angle between overhang and the reduction of overhang pole in key Chinese pole vaulters,and there are also technical changes of shorter trunk swing time in key Chinese female pole vaulters.The characteristics of technical changes of key female pole Vaulters in the stage of energy release are as follows: the key female pole Vaulters in China show the characteristics of technical changes of stretching deviation angle increasing and sports performance decreasing.
