| Against the backdrop of the increasingly fierce technical competition among men's singles players in the world,it is very difficult for Chinese men's singles players to achieve their achievements in international competitions.In the current international form,it is essential for a movement to achieve a long period of successful theoretical research.Because the theory of badminton technology in China is different from other table tennis,swimming and other items,and the theory of badminton technology not only has very important guidance for the improvement of athletes 'technical level,but also provides data for the selection of badminton players in China.Under these circumstances,it is very important to establish the technical theory of badminton players.In this paper,we find the relevant literature and books on badminton.On the basis of this,an expert questionnaire was formulated to screen the indicators and further determine the badminton technical indicator system.Taking 28 video games of the World Badminton Competition from 2016 to 2018 as the research object,12 experts were surveyed using the expert questionnaire method,and the results were collated and analyzed using EXCEL and SPSS software.Using analytic hierarchy process to calculate the weight coefficient of the technical index of the world's outstanding men's singles badminton players,a model of the technical index system of the world's outstanding men's singles badminton players was established,and its athletes were evaluated on the basis of this model.The findings are as follows:(1)The badminton technical indicators identified in this paper include five first-level indicators: serve technology,receive serve technology,front field technology,midfield technology,and backcourt technology.And 24 secondary indicators.(2)On the basis of the final index determination,this paper makes an expert questionnaire of index weight,and uses AHP to get the weight coefficient of each index.The weight coefficients of the five primary indicators are,serving technology(0.151),serving indicator(0.175),front field indicator(0.235),midfield indicator(0.117),back field indicator(0.322),and weight coefficients for each secondary indicator.(3)This article also constructs the grade evaluation standards of the world's outstanding men's singles badminton players 'technical performance,excellent(58.17above),good(54.49-58.17),medium(42.43-54.48),passing(37.83-42.42),poor(37.83below).According to the grade evaluation criteria,we can understand the performance of each athlete,and we can improve the badminton technology of the athlete according to the performance of the athlete.(4)This paper analyzes and evaluates the athletes studied according to the evaluation standards of badminton technical level,including the analysis of the athlete's first-level indicator technology and the analysis of the comprehensive technology.Among them,the highest score in integrated technology was that Jogensen was classified as excellent,followed by Shiyuqi,Qiaonatan and Ansailong.They were classified as good grades.The lowest score was that Quan Chen was divided into poor grades,followed by Zhoutianchengwujialang,and Qiaobin was divided into passing grades.Other athletes 'scores were divided into middle grades.(5)In this paper,the selected research subjects are divided into regions,and the regions are analyzed and compared according to the criteria for evaluating the level of badminton technology established in this article,and it is concluded that athletes from European countries perform best,followed by Chinese athletes.And finally,the performance of other Asian athletes. |
