Research On Technical And Tactical Characteristics And Competition Strategies Of Naomi Osaka On Hard-court Competition

Research background: Naomei Osaka,a back-to-back grand slam champion,a new world no.1 and a young Japanese player,has received little academic research.At the same time,the Chinese women’s tennis level fell into the situation of lack of youth and declining competitiveness,facing the neighboring players in east Asia and the direct opponent of the future intercontinental court.We should do more in-depth research on it,not only to understand its technical and tactical rules,learn from each other,use by ourselves;And can master its skills and tactics advantages and disadvantages,so as to prepare for future confrontation.Research purposes: By studying the winning performance of Naomi Oscka in hard court events,summarizing its technical and tactical advantages and disadvantages in the competition,it lays the foundation for exploring more practical technical and tactics,and provides certain training reference for China’s female tennis players and coaches and guides the nationwide fitness exercise.Research methods: This paper uses the methods of literature,video analysis,mathematical statistics,image analysis and logical analysis to analyze the technical indexes of 1241 points of216 innings in 10 games in 2018 us open and 2019 Australian Open.This paper analyzes the technical use status of each racket technology combined with the use conditions and effect.The main technical indicators include: technical category,hitting depth,hitting line and speed,etc.the speed indicators include the hitting speed and saving speed at the kick-off stage and the stalemate stage.Except that the serving speed is obtained by the original video statistics,the other indicators are all obtained by video The software intercepts the motion picture in the original video and analyzes it.The research mainly uses single factor analysis of variance,independent sample t-test and chi square test to test the difference of relevant technical and tactical parameters.Research results: The results show that the use frequency and the score frequency of the inside and outside corners of the racket are higher than those of the Middle Road,the difference is significant;the use frequency of the forward and backhand technology of the receiving racket is higher than that of other technologies,the depth frequency of the middle and back court is higher than that of the front court,and the pursuit position frequency is higher than that of the forward and backhand position,the difference is significant;the use frequency of the forward and backhand technology of the sending and receiving racket is higher than that of other technologies and the forward and backhand positions The frequency is higher than the body position,the depth frequency of the middle and back court is higher than that of the front court,the difference is significant;the frequency of using the forehand and backhand techniques of the serve and receive is higher than other techniques,the frequency of the forehand and backhand is higher than the body position,the depth frequency of the middle and back court is higher than that of the front court,the difference is significant.Conclusion: 1.Naomi Oscka’s first round performance is excellent,fast,accurate,good scoring effect,and the second round performance is relatively mediocre;2.The receiving and sending rackets use the forehand and backhand techniques to catch up with the opponent’s middle and backcourt areas;3.The serving and receiving rackets use the same technical and tactical characteristics,and both use the forehand and backhand techniques to hit the opponent’s middle and backcourt from two angles;4 In the stage of stalemate,Naomi Oscka technology mainly includes forehand and backhand technology,which mainly chooses the backhand position of the opponent and hits the ball to the backcourt depth.In terms of competition strategy:naomi oscka needs to reduce the gap between different development sequences,no matter in speed or landing point control;and on the basis of maintaining the aggressiveness and stability of forehand and backhand techniques,enrich its own techniques and tactics,and increase the frequency and stability of various techniques.
