| Through the research of many factors that create attacking opportunities in men’s doubles badminton competition,it is found that the rules of the game and the players’ habit of hitting position are of great significance for the players to improve their skills and tactics and win the game.Using the method of literature,sphere trajectory reconstruction,comparative analysis and data analysis,this paper takes 53 sets of matches of the top five groups of elite men’s doubles players in the world in major competitions from 2019 to 2021 as research samples,takes the creation of attack opportunities as the main research point,and redefines the three-dimensional space of the court.Through comparative analysis of the five groups of athletes to create offensive opportunities,cohesion after attack and factors to create attacks in various Spaces,to find out their own strengths and weaknesses,to find others’ strengths,so that the future training and competition to get a better room for improvement.Results:(1)According to the statistics of creating offensive opportunities: Seven techniques were mainly used to create attacking opportunities,including killing,rolling,blocking,blocking,lobbing,pushing and drawing.Among them,the attacking technique created the attack with the highest proportion(51.2%),the transitional technique created the attack with 31.3%,the defensive technique created the attack with 13.8% and the serving technique created the attack with 4.3%.(2)There are some differences between the five pairs in terms of creating offensive opportunities:Li Junhui and Liu Yuchen created the most attacking opportunities and used the most blocking techniques after killing the ball,indicating that they had a great threat to kill the ball.Kaiwu Yueda and Kenshi Kawamura created less attacking opportunities,and rarely used the drop ball technology in the backcourt attack.Too much killing did not bring many blocking opportunities,indicating that they had little threat to kill the ball.(3)The cohesion after attack can be divided into three types: continue attacking after attack,defend after attack and transition after attack.Among them,Li Junhui and Liu Yuchen have the best cohesion,the proportion of continue attacking after attack is more,the proportion of attack to defense and the sum of attack to transition is the least,while Kaiwu Yuada and Kenshi Kawamura have the worst cohesion,the proportion of continue attacking is the least.The ratio of offense to defense was the largest;(4)Li Junhui and Liu Yuchen of the Chinese team #13>#14>#15,indicating that their forehand creates more attacks than their backhand.The two pairs of the Indonesian pair created the most attacks in #2 space and #11 space,indicating that they have a strong ability to create attack opportunities when receiving the serve.The two Japanese pairs created more attacking chances in #4,#5,and #6 Spaces,which belonged to the defensive area,indicating their strong defensive ability and defensive frequency.Conclusion:(1)According to the score and loss ratio of each technique,the blocking,killing and lob were defined as offensive techniques,the blocking,picking and lob were defined as defensive techniques,and the six techniques of lob,washball,net setting,hook,push and draw were defined as transition techniques.(2)According to the situation of each stroke creation attack in men’s doubles match,the number of attack opportunities created by the receiving side is always better than that of the serving side,showing a curve of one high and one low.With the increasing number of beats in the match,the number of attack opportunities created becomes less and less,showing a decreasing trend on the whole.(3)The Chinese badminton team should continue to adhere to the guiding ideology of "attack first".More attack means less defense and transition.The scoring efficiency of attack is far higher than that of defense and transition.(4)In the 18 Spaces,attacking opportunities are mainly distributed in the upper space,including #11,#13,#14,#15,#16 and #17,while in the lower space,it is mainly dominated by #2 space. |
