Construction And Empirical Research Of Statistical Method Of "3+4" Segment Of Table Tennis Technique And Tactics

In order to adapt to the constant reform of the rules of table tennis,the players' technical and tactical skills are improving day by day.In order to make a more comprehensive and detailed statistical analysis of the players' skills and tactics,based on the traditional table tennis skills and tactics three-stage index evaluation method,this paper selects the four-stage index evaluation method of table tennis skills and tactics combined with the three stages of the opening,middle and last games divided by the competition process to form the "3+4" statistical method.The 10 matches of fan zhendong and xu xin were statistically analyzed by means of video observation,data comparison analysis and empirical research.The conclusions are as follows:1 Through statistical analysis of several common technical and tactical statistical methods,it is found that in the statistics of 89 games,only one game in the traditional three-segment index evaluation method matches the corresponding relationship between the gains and losses of the traditional three-segment index evaluation method.The non-correspondence problem is prominent;the 89-game match data in the four-segment index evaluation method is one-to-one correspondence,but there is a problem that the overall data of a single statistical method tends to be average;Therefore,a single technical and tactical theoretical analysis method cannot fully reflect the required data.Therefore,traditional technical and tactical statistical methods must be supplemented,improved,and further detailed to make the statistical results more accurate and provide a strong guarantee for the development of further game plans.2 In order to verify the scientificity and necessity of the four-paragraph index evaluation method selected by the "3+4" statistical method,the four-paragraph index evaluation method is compared with the traditional three-paragraph index evaluation method through individual cases and overall data statistics.The results show that: Four index evaluation method of statistical data after one to one correspondence,two methods of statistical data difference obvious,Fan Zhen Dong differs 50 points,10 games Xu Xin differs 60 points,four index evaluation method compared with traditional three index evaluation method rob section of the total number of points to increase,the American section points decreases,and the traditional index assessment method of three hair grab capability assessment ability and the American paragraphs appear bigger difference,the change of the data is also the coach on the pitch in recent years the intuitive feelings and statistical data from one of the reasons.3 In empirical research,the statistical analysis of the match between Fan Zhendong and Xu Xin using the "3 + 4" statistical method shows that: breaking the traditional single technical and tactical statistical method,combining the two statistical methods,itcan be changed from different At different levels,the game is analyzed from different angles.The "3 + 4" segment statistics method can be seen through the serve round(the grab section and the stalemate I section)and the serve round(the grab section and the stalemate II section)in combination with the start,middle,and end of the game.Athlete's technical and tactical performance in various stages;using the three innings of the game process to combine the service round(starting and stalemate I)and the receiving round(receiving and stalemate II)to see the player The use of techniques and tactics in various sections.4 In the comparison and analysis,the use of "3 + 4" period of statistics respectively with four index evaluation method and the process of game three games to Fan Zhen Dong and Xu Xin 20 games data statistical analysis,the results show that the use of "3 + 4" period of statistics give the analysis of athletes,the analysis of the results than using a single four index evaluation method and the process of game three games for more detailed and comprehensive;The problem of data mismatch and the average of the whole data of single statistical method is solved,and the problems of the athletes in the process of competition can be found accurately.
