Research purpose: To analyze the moving characteristics of top tennis players in singles matches,to obtain their moving distance and speed characteristics,and to study the correlation between moving distance and speed and the outcome of the game.Discriminant.Sort out and analyze the various movement steps in the tennis match,and get the proportion of the use of tennis movement steps in the game,as well as the statistical analysis of the frequency of the various steps used in the court area,and get the comparison scores of the various steps.contribution.Provide theoretical support for the formulation of tennis coach training programs and tennis player training in China.Research method: This article downloads high-quality live transcribed videos through multimedia and CCTV,and selects the top eight players in the ATP year-end 2018 in the world.The hard court includes the Australian Open and the US Open,and the clay court is open for French tennis.The Wimbledon Tennis Open is a total of 32 games.The main research object is the movement characteristics of tennis players under the conditions of the game.The video analysis software SIMI Scout was used to analyze the movement characteristics of tennis players,and the obtained data was sorted and statistically analyzed.The overall characteristics of the movement characteristics of male tennis players' singles matches were analyzed.Analysis conclusion:(1)The average moving distance of losing athletes is 3128.281 meters,while the average moving distance of winning tennis players is 3136.375 meters.(2)The average speed of the winning athletes in each game is 2.523 ± 0.053 m / s,while the average speed of the losing side is 2.522 ± 0.062 m / s.(3)The average speed of the athletes who win the game is 7.88 ± 0.11 m / s,while the average speed of the losing player is 7.598 ± 0.282 m / s.(4)Through the Bayes discriminant function,you can determine the athlete's winning or losing.Win: Y =-2516.43 + 662.226 × maximum speed;Lose: Y =-2707.2 + 686.876 × maximum speed.(5)Athletes have the least distance to move during anaerobic high-intensity running,and aerobic low-intensity running has the largest proportion.Oxygen-intensity running accounts for 21% of the total moving distance.(6)In the proportion of all kinds of mobile steps used in tennis games,open step> cross step> closed step> slide step> break step adjustment> run> jump step(7)The open frequency is higher in the right-hand area,and the closed frequency is higher in the left-hand area.The area where cross-steps are most frequently used is still in the bottom line area.The usage rate of sliding steps and broken steps is very high in the whole court,and the frequency of running in tennis is low.(8)Open steps are easier to achieve scoring than closed steps.The contribution of other steps to the gain and loss points is more balanced.The use of skipping steps mostly occurs in the stalemate phase,and the contribution to the gain and loss points is small.
