Since the Rio Olympic Games,the European badminton players represented by Anselong have brought impact and challenge to China and even the world badminton.As a representative figure of men’s singles of European countries,Ansilong is ranked No.1 in the world at present.This paper analyzes and summarizes the skills and tactics characteristics of Ansilong in Rio Olympics and Tokyo Olympic Games,and

to analyze the differences in the ratio of technology use,scoring rate,utilization rate and other indicators of the two Olympic Games,summed up the technical and tactical use ability and tactical characteristics of Acelon in the two Olympic Games.Results:(1)Hair extension stage:In Tokyo Olympic Games,the percentage of use of service point in position 5 area(17.9%)was significantly lower than that in Rio Olympic Games(2.8%)(P<0.01),but the percentage of use of service point in position 1 area(6 5.3%)was significantly higher than that in Rio Olympic Games(45.4%)(P<0.01).In Tokyo Olympic Games,the proportion of use of serve and pick by Anseron(26.8%)was significantly lower than that in Rio Olympic Games(40.6%)(P<0.01).The proportion of receiving and pushing of Anseron in Tokyo Olympic Games(22.9%)was significantly higher than that in Rio Olympic Games(10.7%)(P<0.01).The proportion of use of first and third stroke combination service control in Tokyo Olympic Games(5 5.1%)was significantly lower than that in Rio Olympic Games(68.6%)(P<0.01).The proportion of first and third stroke combination service attack used by Anserong in Tokyo(2)Restricted stage:The proportion of use of push ball in restricted stage of Tokyo Olympic Games(12.6%)was significantly higher than that in Rio Olympic Games(6.9%)(P<0.01).The proportion of use of high range ball in restricted stage of Tokyo Olympic Games(3.8%)was significantly lower than that in Rio Olympic Games(13.9%)(P<0.01).The proportion of lob in restricted stage in Tokyo Olympic Games(26.1%)was significantly higher than that in Rio Olympic Games(16.8%)(P<0.01).The usage rate of passive pumping[(technical points+technical points lost)/(total points+total points lost)]in restricted stage of Tokyo Olympic Games(14.6%)was significantly higher than that in Rio Olympic Games(1.9%)(P<0.05).(3)multi-shot stage:The percentage of use of the multi-shot stage in the Tokyo Olympic Games(13.8%)was significantly higher than that in the Rio Olympic Games(7.4%)(P<0.01).In the Tokyo Olympic Games,the proportion of use of the multi-shot rolling(24.5%)was significantly lower than that in the Rio Olympic Games(32.1%)(P<0.01).The utilization rate of the multi-shot block technology in Tokyo Olympic Games(3 6.8%)was significantly lower than that in Rio Olympic Games(69.6%)(P<0.01).The proportion of use of long shot in Tokyo

were(100%)and(37.0%)significantly higher than that in Rio Olympic Games(66.7)and(37.0%),respectively.The difference was significant(P<0.05)or very significant(P<0.01).The conclusion is as follows:(1)In the receiving stage of the service,Acelon in Tokyo Olympic Games has a better sense of technical and tactical attack than in Rio Olympic Games,which is reflected in the increased proportion of high backhand service;The proportion and usage rate of service receiving and pushing increased significantly,while the proportion of service picking decreased.The proportion of the first and third racket service attacking tactics was significantly improved.(2)In the restricted stage,the technical and tactical use of Ansellon Tokyo Olympic Games is more stable and diversified than that of Rio Olympic Games,which is reflected in the improved scoring rates of various techniques in the front court and the significantly improved scoring rates of the straight line blocking techniques in
