Research On The Characteristics Of Line Change In The Stalemate Segment Of Outstanding Female Table Tennis Players

By using the methods of literature,video observation,mathe matical statistics and comparative analysis,this paper makes a statistical analysis of four outstanding female athletes,Ding Ning,Liu Shiwen,Zhu Yuling and Chen Meng,in 2017-2019,each of them has 10 competitions,40 in total.This paper divides the forehand,backhand and the Middle Road,analyzes their technical and tactical situation in the stage of the match between the serving wheel and the receiving wheel,mainly analyzes their line changes in different directions and the use of line combination,from the qualitative and quantitative perspective,to explore the common characteristics of the line changes and the use of line combination of excellent women players in the stage of match And find their advantages and disadvantages.Through the analysis and research of these characteristics,it can provide some reference for improving the use level of techniques and tactics in the Stalemate Stage and future training and competition.Through research and analysis,the following conclusions are drawn:1.There are both individuality and commonness in the line change of the stalemate section of excellent female players.There are commonness in the round of stalemate.The ability of three consecutive boards is relatively concentrated.The service road is concentrated in the 5th,7th and 9th boards,and the receiving and sending wheels are concentrated in the 6th,8th and 10 th boards.In addition to the straight line of the Middle Road,the straight line is relatively less used,mainly the diagonal line.In the line combination,the middle road and the opposite line are obviously used The main strategy is to adjust the forehand.The personality lies in that different players have different ability to use different lines in different forms.2.Forehand position changing line: excellent female players generally use less 28.30% of forehand to forehand stalemate on the service wheel,and the score loss rate of poor effect is 52.22%.Forehand to backhand and forehand to middle are used most,and the effect of changing line is relatively ideal;the score of forehand position changing line on the receiving wheel is greater than the score loss,and the effect of forehand to forehand stalemate is better than that on the service wheel,and the middle is also used And backhand as the main choice,relative to the overall balance of the serving wheel.Among them,Zhu Yuling is the most obvious one in the middle of the road,with47.52% of serving wheels and 44.12% of receiving and serving wheels.3.For the backhand position changing line: the serving wheel and receiving wheel are also dominated by backhand holding and backhand changing the middle way.The use rate of backhand changing line to forehand position is only 37.71%,but the effect ofbackhand to forehand changing line is better in quality and the scoring rate is higher.The score loss rate of continuous backhand stalemate is relatively high,which needs to be improved.Among them,Zhu Yuling,the effect of backhand to forehand use is poor,the score rate is only 36.36%,which is significantly lower than the other three players.The score loss rate of Ding Ning from backhand to Middle Road is high,which reaches77.78%.We should pay attention to reduce the error of strong practice.4.In the middle position changing line: choose the continuous middle straight line holding and the middle to backhand diagonal holding as the main choice,but the overall effect of the middle straight line holding of the serving wheel is not good,the highest score loss is 52.25%,the effect of the middle to backhand diagonal holding is relatively good;the effect of the middle straight line holding of the receiving wheel is better than the serving wheel as a whole,in which Liu Shiwen is on the middle to backhand diagonal line of the receiving wheel The application effect is the best,and the score rate reaches 82.35%,which is significantly higher than other methodsThe players are high,but the middle straight line stalemate phase needs to be improved.5.After entering into the stalemate,the line changing or non line changing stalemate will be carried out on the continuous three board line combination with the middle route and backhand as the main breakthrough point,and the large angle line transfer of the excellent female players on the line combination with the forehand as the starting point will be the main feature,others will be dominated by the backhand and middle route adjustment,and the active stalemate and potential will be more in the stalemate state,and the pressure backhand and middle route adjustment will be the main feature Attack)forehand is the main feature.Liu Shiwen,Chen Meng and Ding Ning are more obvious on the active whole platform transformation line.Zhu Yuling is slightly short of continuous pressing middle road and backhand.
