Construction And Application Of Tactical Diagnostic Index System In Men’s Badminton Singles Match

It is an important guarantee to improve the athletes’ competitive ability to scientifically construct the tactical diagnostic index system of badminton men’s singles match,accurately diagnose the players’ tactical stage ability and systematically monitor the development of their tactical level.So far,there is no construction of diagnostic index system of badminton tactics from the two perspectives of serve and return,and no research on the relationship characteristics of each tactical stage.Given tactics in the badminton men’s singles competition,the importance of this research in the badminton men’s singles player events in 2016-2019 was conducted in 64 games,video observation,mathematical modeling method was used to construct the badminton men’s singles players tactical diagnosis index system,for the Chinese men’s singles badminton players to improve,improve the tactical level provide a reference basis;It can also enrich the theory of specific tactical level of badminton.The main conclusions are as follows:(1)On the basis of empirical analysis and expert experience analysis,from the perspective of receiving serve,the tactical diagnostic index system of badminton men’s singles was constructed and the corresponding evaluation criteria were established:four first-level indicators were included;Eight secondary indicators.(2)From the perspective of time and space,take the second-level diagnostic indicators of eight tactical links as examples to demonstrate the effectiveness of the eight tactical stage indicators;The indexes of the eight tactical stages have consistent stability in different time and space,which can stably reflect the overall competitive strength level of athletes.(3)through the multiple regression model,BP neural network model,analysis of path coefficient analysis of eight tactics index of discovery:1)the importance of each tactical stage for athletes,the athletes influential tactical stages as follows:restricting Ⅰ,receiving,take many Ⅱ,restrict Ⅱ;2)player interaction effect between each tactical stage,limit Ⅰ,receiving ability stronger,makes other tactical stage have a positive effect to win the game,manifests the limit Ⅰ,receiving is the decisive factor to the victory;Limiting Ⅱ good play,can promote limit Ⅰ repelling,take many Ⅰ,receiving,limit Ⅱ efficiency,to improve the game winning probability,reflects the limit Ⅱ is the key to winning factors;The service stage has less influence on the match through other tactical stages.3)Both the BP neural network model and the multiple regression model have a high degree of prediction,which confirms the correctness of the model constructed in this paper;The prediction accuracy of BP neural network model is better.(4)in the diagnosis of index system of application study found:1)real-time detection:peach Tian Xian bucket of limit Ⅰ,take many Ⅱ,restrict Ⅱ tactical stages are in a good level of above,the victory has vital role;Shi Yuqi Ⅰ limit Ⅰ,American limitation in the game,more Ⅰ,receiving,restrict Ⅱ,pat Ⅱ tactical stages are at best,is the key to win.2)Tracking diagnosis shows that:from 2017 to 2019,the efficiency of Shi Yuqi in the decisive tactical stage shows an increasing trend year by year,and the competitive level keeps improving;From 2016 to 2019,Chen Long’s efficiency gradually declined in the decisive tactical stage,and improved in the multi-beat stage,but his overall competitive ability showed a downward trend.
