Technical And Tactical Characteristics And Competition Strategies Of Lee Chong Wei's Key Points

The high-level competition of outstanding athletes is a comprehensive competition of collective ability,technology,tactics,psychology and intelligence.Due to the improvement of scientific training methods and means and the improvement of training facilities,the training level of athletes from all countries has generally improved,and the difference between the components of competitive ability is very small.The effective handling of key points is more important to the competition results.The research purpose of this paper has two aspects: first,it aims to accurately and objectively explore the characteristics of Lee Chong Wei's application of "key points" in major competitions;Secondly,according to the characteristics of Lee Chong Wei's key points and tactics,the competition strategies of Lee Chong Wei and his opponents were worked out.In this paper,the key technical performance of 10 representative matches of 1/4,1/2 and final in the 2016-2018 Olympic Games,badminton world championships and badminton open was selected as the research object.Video observation method was used to obtain the technical application conditions,technical application status and technical application effect parameters to be studied in this paper.Adobe premiere was used to freeze the target video to the minimum unit frame to obtain the Angle parameters of the lower Angle.In this paper,the research data were divided into two categories: scoring balls and losing balls,and the difference analysis of relevant technical parameters was conducted by using one-way anova and paired sample T test.Univariate analysis of variance(anova)was performed on the distribution of the technical use of the scoring or losing balls,and the paired sample test was performed on the difference analysis of the technical use between the winning and losing balls.The research results obtained in this paper include two parts: the technical and tactical application characteristics of Lee Chong Wei's key points and the competitionstrategy of Lee Chong Wei's key points.Among them,the technical and tactical application characteristics of Lee Chong Wei's key points include the conditions,conditions and effects of Lee Chong Wei's key points in the first beat,and the conditions and effects of the second and multi-beat techniques and tactics.The competition strategy of Lee Chong Wei's key points includes Lee Chong Wei's competition strategy and Lee Chong Wei's competition strategy.The following conclusions are drawn from the summary:Characteristics of Lee Chong Wei's Key Points,First Shot Technique and Tactics:Lee Chong Wei is used to serving backhand forehand,and pays attention to using net releasing technique when receiving service,mainly controlling opponent's frontcourt middle area and backhand position area.Under the leading condition,more aggressive net releasing techniques are used and the playing method is relatively mild when split evenly.Most of the first strokes have a uniform effect,and the loss of points is mainly based on the opponent's backhand position.The characteristics of Lee Chong Wei's technique and tactics in the second shot of key points: the declination angle is not the key technical parameter that affects Lee Chong Wei's score and loss,while Lee Chong Wei's main technique in the second shot is the lob,with poor net setting effect.The points lost were concentrated in the forehand position area in the front court,while the backhand position in the front court scored high.The characteristics of Lee Chong Wei's multi-beat technique and tactics in key points: Lee Chong Wei's key points belong to the multi-beat stage,with a relatively high score ratio of about 6 beats,and then the score shows a downward trend as the number of beats increases.It is mainly to hit the opponent's backhand area in the front court.The net laying technique is favorable for scoring,and the effect of picking the ball is poor.Formulation of Lee Chong Wei's Key Points Competition Strategy: By analyzing the technical and tactical characteristics of Lee Chong Wei's key points,the competition strategy of Lee Chong Wei and his opponents at the key points was formulated.
