The Building And Analyzing Of Zheng Jie Tennis Women' Singles Match Competitive Performance Model

With the development of modern tennis, the competition becomes more and more fiercely, therefore improving match monitoring has already became one important part to complete the general competitive strength of China's tennis.This study mainly focus on Chinese women's tennis player Zheng Jie's game video in recent years, by the statistical analysis in some indicators, and through building their individual sports model analyze its various stages of athletic performance for athletes athletic training and competition provide valuable monitoring and theoretical support. While the model building and researching on tennis players performance, will also accelerate tennis development of the theory, technical and tactical application of the principle to provide such a valuable reference.In this paper,literature,video observation,and mathematical statistics. Through the competitive tennis element analysis of the literature review to identify the competitive performance of constituent elements,and through video statistics,the use of mathematical methods to establish the performance of athletes competitive model,analyzing different stages of their technical and tactical performance.Research outcomes: (1).Tennis athletic performance suited to a comprehensive evaluation index system and using multiple regression to build mathematical methods;(2).Athletic performance adopt score and lose points with the difference to establish contacts with the various indicators and statistical studies;(3).Set play as basic unit in statistical analysis and differentiating between serve area and receive area make more smaller difference compared to the comparison of data systematic in whole court;(4).It's better to use 4 parts to study tennis competition performance,those are"serve section "serve stand-off section","receive section" and"receive stand-off section".The outcomes showed that,by the analysis of Zheng Jie's competitive performance model construction, a scoring percentage in different section of indicators and targets by processing segment usage analysis of Zheng Jie of the competitive performance of tennis has a good effect. In the part of technology use, Zheng Jie should improve the scoring rate in the section of serve stand-off, at this stage of the competition performance has a greater degree of impact on their athletic performance; in the part of tactical use,we suppose Zheng Jie increase the rate of"receive stand-off"in the technical conditions remain unchanged, to keep game continuously after stand-off section into multiple rounds of competition,it will present a higher practical value in her performance.
