Study On The Technique And Tactics Diagnostic Methods Of Males Table Tennis

With the reform of the competition rules of table tennis and the continuous development of the technique and tactics of table tennis,how to make the scientific diagnosis of the technical and tactical ability of table tennis athletes to meet the needs of preparing for the world series matches for the Chinese national team,and making the technical and tactical training and competition for other levels of teams,which is very important issue in front of us.In this study,based on the existing three-stage index evaluation method,using the methods such as the literature,expert interviews,video observation,mathematical statistics and so on,the author deeply excavate the question about the application of the three-stage index evaluation method under the background of the changes of the rules,deeply interpret the connotation of the three-stage index evaluation method,then design the ideas and methods to empirically develop and improve the three-stage index evaluation method and carry out the empirical ways to perfect the diagnostic index system of the three-stage index evaluation method,and on this basis,the corresponding evaluation criteria are formulated.Though above study,the main conclusions are followed:Conclusion one:The continuous reform of the rules and the continuous development of technology causes the existing problems in the application of three-stage index evaluation method,as well as scholars develop and perfect the three-stage index evaluation method,there are some questions among them such as the unified views,the lack of systematic empirical analysis and so on,which causes that making the empirical ways to develop and perfect the three-stage index evaluation method has become the urgent problem at present.Conclusion two:From the connotation of the three-stage index evaluation method and the problems existing in the application,this study designs the six steps empirical analysis theory to develop and perfect three-stage index evaluation method.The six steps are:First,the characteristic analysis of technique and tactics of each scoring-loss board at the new stage;Second,the causes analysis of the technique and tactics of each scoring-loss board;Third,the application effect and causes analysis of the serving round and the receiving round;Fourth,the analysis of the relationship between the 5th,6th board and the corresponding front boards and later boards;Fifth,the relative analysis of the characteristic of the technique and the tactics each match;Sixth the dynamic changes analysis of the characteristic of the technique and the tactics each match.The results of the empirical analysis show as followed,the six steps can be better to achieve the phase division of the overall competitiveness of the table tennis players and the phase definition of the scoring-loss board.Conclusion three:Though the empirical analysis,based the three-stage index evaluation method,the author develops the diagnostic index system from the three-phase to the three-phase and two plates index evaluation method,which are respectively the serve-then-aggress part,the receive-then-aggress part,the serve-then-aggress convergence part,the receive-then-aggress convergence part and the rally part.Among them,the serve-then-aggress part concludes the 1st board and the 3rd board;the receive-then-aggress part concludes the 2nd board and the 4th board;the serve-then-aggress convergence part concludes the 5th board,the receive-then-aggress convergence part concludes the 6th board,the rally part concludes the 7th boards and the subsequent boards.Conclusion four:Based the three-phase and two plates index evaluation method,with the formulation method of the evaluation standard of the classic three-stage index evaluation method for reference,based the technical and tactical statistical data from Three world table tennis competition of Chinese excellent table tennis athletes,the author uses the statistical method and experts experience method to formulate the evaluation standard of the three-phase and two plates evaluation method.Conclusion five:the comparison of application effects between the three-phase and two plates index evaluation method and the three-stage index evaluation method shows that,the three-phase and two plates index evaluation method can be better to reflect the nature characteristic in the new ball era of the development of technique and tactics of table tennis,it can more accurately realize the diagnosis of the technical and tactical ability of table tennis athletes in the new era,and can more deeply reveal the characteristic of the application of technique and tactics of the first four boards to develop in-depth to the 5th,6th board,which also further highlights the key role of the convergence part and the position in the overall athletic ability.Conclusion six:From the facts of the continuous development technology of the world table tennis and the practical need of preparing for the World Series for the national table tennis team,the author thinks that the three-phase and two plates index evaluation method in the future development should timely improve myself according to the latest development of the world table tennis technology,then continue to strength the coupling of the multimedia technology,should constantly deepen the organic integration with the other analysis methods of the technique and tactics and the inferential statistical methods,and we should fully appreciated longitudinal tracking studies.
