Chen Qingchen/Jia Yifan,China's Elite Badminton Women's Doubles Player Characteristic Analysis Of Gain And Loss Points

In this paper,China's elite badminton women's doubles players Chen Qingchen/Jia Yifan in the World Championships,Asian Games,Sudiman Cup,Uber Cup and the Open Championships against five elite foreign players(Matsumo Meizuoji/Takahashi Lihua,Polly/Johari,Lavinda.Zonggongpan/Kittitarakul,Peterson/Wright,Zhang Yina/Lee)Shaoxi)Fifteen matches were videotaped.By using the methods of documentation,video observation,mathematical statistics and comparative analysis,this paper compares the application of techniques and tactics of Chen Qingchen/Jia Yifan in the competition,and analyses their main scoring means at the offensive end through the last two beats and the combination of lines when they score actively,and Chen Qingchen/Jia Yifan when they lose points passively.The last two rackets of the opponent's technology and the type of misclassification are used to analyze the problems existing in Chen Qingchen/Jia Yi-fan's defensive side;the stability of Chen Qingchen/Jia Yi-fan's various techniques is analyzed through the use of non-forced misallocation;and Chen Qingchen Chen/Jia Yi is analyzed through the service landing point and receiving technology combined with the service gain and loss situation.Whether there is a gap between them and other excellent players in terms of delivery and delivery.Through the research,the following conclusions are drawn:1.In the aspect of active scoring,Chen Qingchen/Jia Yifan upholds the “offensive-oriented” approach of women's doubles in our country and has strong offensive ability.In the competition,they mainly create active scoring through the combination of killing and killing techniques.Their active scoring is higher than other combinations.The small slant line is the most commonly used route in their attack.Relatively speaking,Chen Qingchen is good at organizing in front of the net,while Jia Yi-fan has stronger backcourt offensive ability and more lines.Jia Yi-fan's “backcourt attack” and Chen Qingchen ‘s “front cover” are their dominant positions.When either of them launches a small oblique attack from the forehand area to form a double pressure in the midfield,they can exert their greatest offensive power.2.Chen Qingchen/Jia Yifan's passive scoring techniques are mainly picking and dribbling,with the highest scoring in catching and killing the ball,followed by catching and dribbling.In the process of defense,the changes of the two players are relatively small.In many cases,they are just homeopathic,the purpose of playing is not strong,the offensive nature of defense is not enough,and their forced mistakes are higher than others.Fifth,the defensive ability of the world's top women's doubles is slightly inadequate.In the match,Chen early morning overemphasized the use of forehand to deal with the overhead area of horizontal dribble,but the treatment effect was not good,more passive points were lost in the stalemate,Jia Yifan made more defensive errors on the left side of his close body,and his foot moved slowly.When the opponent suddenly used the net drop ball after a series of killing,they could not follow up in time under their feet,and the two men were attacking.The percentage of passive scoring caused by opponent's grasping habitual ball path is also significantly higher than that of other combinations.3.Chen Qingchen/Jia Yifan's non-forced mistakes are obviously higher than those of foreign players.The highest proportion of non-forced points is killing,followed by hanging ball.The main types of errors are off-line and off-line.Their technical “stability” and “accuracy” are not good enough.Jia Yifan's non-forced errors are much higher than Chen Qingchen ‘s.In addition,their division of labor on the court is not clear enough,and their cooperation is not tacit enough.They often make unforced errors by running for positions or competing for balls.4.The score of service and reception of Chen Qingchen/Jia Yifan is basically equal to that of foreign players,but in the face of tall players with fierce pressure in front of the net,there are more errors in service and reception;Chen Qingchen/Jia Yifan mainly serves in Area 1,combined with Area 5 in the back court;the use rate of killing is the highest when receiving service from the opponent in the back court,and the use rate of pick-up is significantly higher when receiving service from the opponent in the front court than when receiving service from the opponent.Most combinations.On the whole,Chen Qingchen/Jia Yifan has no absolute advantage in the receiving and receiving stage,especially in the crucial time,the rhythm and the landing point of the ball are not well grasped.
