| The change of attack and defense runs through the whole process of badminton competition.Mastering the law of attack and defense conversion is the theoretical foundation of improving individual competitive level.However,the conversion of attack and defense of badminton lacks quantitative index and objective data analysis,which makes it a theoretical system.Therefore,through the methods of literature,statistics and comparative analysis,this paper collects and statistics the technical and tactical information of 17 matches of the combination of Li Junhui / liuyuchen,yuanteng Dayu / Watanabe and Gideon / sukamuyo.Based on the determination of the attacking and defending attributes of the technology,the author uses the combination of techniques to determine the occurrence and type of the attack and defense transformation.Then,by re constructing the badminton space-time structure,the author tries to find the space-time characteristics and the reasons of the change in the world high-level badminton men's doubles competition,which provides theoretical support for the training and competition of high-level athletes.The conclusions are as follows1.in the combination of attack to turn and defend,push and turn gear is the most likely technology combination;The probability of attack to defense is from high to low: yuanteng from / Dubian Yong Da,lijunhui / liuyuchen,Gideon / sukamuyo.The kill and turn stop is the lowest technical combination of Li Junhui / liuyuchen;The technique combination of the lowest probability of attack to defense is the jump gear;The technique combination with the lowest chance of attack and defense is to take place in Gideon / sukamuyo.2.in the combination of defensive special attack technology,the probability of turning the ball into attack is much higher than that of picking the ball to attacking;The probability of defending and turning to attack is from high to low: yuanteng from/ Dubian Yong Da,lijunhui / liuyuchen,Gideon / sukamuyo.The blocking and turning killing is the highest technology combination of Li Junhui / liuyuchen,and the selective kill is the lowest probability;The technology combination of the most likely defensive and defensive turn attack is the technique combination of the far rattan big from / the Dodo brave guard,and the flip flop is the lowest probability technical combination;The blocking push is the most likely technical combination of defensive and turnover attack in Gideon / sukamuyo,and the technology combination with the lowest probability of pick and turn killing.3.the height of 3 shots of attack and defense technology combination is generally the first shot,the second shot and the third shot;Gideon / sukamuyo is the lowest in the first and third shots of the attack and defensive technology combination;The high utilization ranking of attack and defense: Gideon / sukamuyo,Li Junhui /liuyuchen,yuanteng Dayu / watanayong.4.the height of 3 shots of defensive and turn attack technology combination is generally the third shot,the second shot and the first shot;The first,second and third shots in the technical combination are the least likely to occur in the 0-0.5m range;The space utilization ranking of defensive and changing attack: Gideon / sukamuyo,yuanteng Dayu / watanayong Da,lijunhui / Liu Yuchen.5.the attack and turn defensive speed is mainly concentrated in the ball speed range of 20-40 M / s;The probability of attack to defense in the long and low speed range of the big rattan from / to the Watanabe is higher than the other two pairs;The ranking of the use of attack and defensive speed: yuanteng University from /watanayong University > lijunhui / liuyuchen > Gideon / sukamuyo.6.the speed of defensive turnover mainly focuses on the range of 20-40 M / S;In high level competition,the ball speed of more than 60 meters / second is difficult to change from defensive to attacking;The ranking of the use of defensive turnover speed: yuanteng University from / watanayong University > lijunhui / liuyuchen >Gideon / sukamuyo. |
