Research On Defense Effect And Formation Optimization Of Chinese Women’s Volleyball Team In Tokyo Olympic Cycle

With the rapid development of modern volleyball,the world’s women’s volleyball is becoming more and more masculine,moving towards the direction of strength,speed and high common development.As the endpoints of two different directions,attack and defense are interdependent and common development.The continuous strengthening of the offensive end requires that the level of the defensive end should also be improved,so that there is defense in attack,attack in defense,and always adhere to the idea of both attack and defense,full attack and defense.The level of Chinese women’s volleyball team in the offensive end has reached the world level,but there are still many problems in defense,which need to be solved.This paper starts with four aspects of volleyball defense: receiving serve,receiving spike,receiving treatment ball and receiving and blocking back ball.By using kinovea software,the defense effect of Chinese women’s volleyball team in 2018 World Women’s Volleyball Championship,2019 World Women’s Volleyball League and 2019 women’s Volleyball World Cup is statistically analyzed.And use the literature method,correlation analysis and other scientific research methods to analyze the statistical data comprehensively,and draw the following conclusions:1.Receiving and serving: the Chinese women’s volleyball team can better ensure the quality of the first pass,the arrival rate of receiving and sending floating ball and the front upper hand service is relatively ideal,and the arrival rate of receiving and sending strong jump service needs to be improved;the receiving and serving technologies adopted by the Chinese women’s volleyball team are mainly body side two hand and front two hand,and the defensive effect of using these receiving and serving technologies is high;Gong Xiangyu,Wang Mengjie Zhang Changning and Zhu Ting are the main receiving and serving players,the receiving and serving effect of Zhang Changning needs to be improved;the receiving and serving defensive players can prevent the ball falling in the landing area with high quality;through analysis,it is found that there is no correlation between the defensive effect of receiving and serving in different aspects and the defensive effect of receiving and serving.2.Receiving and spiking: the Chinese women’s volleyball team can basically form the formation of two or three person block and back row defense when defending the attack of position 4;the Chinese women’s volleyball team often uses one hand cushion,body side two hand cushion and front two hand cushion when defending the spiking;among the main receiving and spiking players,Ding Xia is a more prominent second setter in defense,and Wang Mengjie’s overall receiving and spiking defense effect is relatively good People are satisfied,Zhu ting and Gong Xiangyu’s defensive effect of receiving and spiking is relatively stable;through analysis,it is found that the defensive effect of receiving and spiking is generally poor in No.4,5,7 and 9 areas;there is a close relationship between receiving and spiking technology and individual receiving and spiking effect and receiving and spiking defensive effect.3.Receiving and handling the ball: when receiving and handling the ball,the front two hands are used most frequently,and the defensive effect of the ball receiving and handling the net once or twice is not as good as that of the ball passing the net three times;the ball falling point of the opponent handling the net is relatively concentrated in the middle part of the field;through analysis,it is found that there is a close relationship between receiving and handling the ball and the defensive effect of receiving and handling the ball.4.Receiving and blocking the ball: when receiving and blocking the ball,both hands on the side of the body make the most use of the ball,and the defensive effect of using this receiving and blocking the ball is relatively good,followed by one hand,but the defensive effect of receiving and blocking the ball with one hand is not so good;the defensive effect of Chinese women’s volleyball team in position 4 is better,but the defensive effect of blocking the ball in position 2 and 3 is not so good;through analysis,it is found that receiving and blocking the ball back There is a close relationship between the skill and the defensive effect of catching and blocking the ball.According to the statistics of the defensive positions of the Chinese women’s volleyball players in the competition,and according to the above shortcomings and conclusions,the following suggestions are put forward:1.Improve multiple receiving techniques;2.Enhance the training of reaction ability;3.Improve personal defense ability;4.Adopt the method of combining individual defense and collective defense in special area;5.Strengthen the cooperation consciousness among teams;6.Optimize the receiving and serving formation,receiving and spiking formation,receiving and handling formation and receiving and blocking back formation.6.1 optimize the receiving and serving formationAccording to the different nature of the serve,the different service center and other docking service formation,the different degree of fine-tuning.Chinese women’s volleyball team should learn to adjust the position formation in time according to the characteristics of different countries,different attacking ways and different serving players.6.2 optimize the receiving and spiking formationChinese women’s volleyball team should make corresponding defense strategies for our strong opponents,such as the fast break based play in the United States,the Italian No.2 position,the back row attack based play,etc.We should make different defensive formation according to the different nature of the ball,the ball from different positions and the concentrated position of different spiking.In the game,we should make the fine-tuning of the position according to the playing style of different countries without changing the basic position formation.Learn to adjust freely.The players with better defense of receiving and spiking should actively expand their receiving range.The players in the back row should undertake more receiving tasks than those in the front row.6.3 optimize the receiving and handling formationThe Freeman should take the main part in the middle,and the other two players in the back row should protect the front row players to form a defensive formation close to the middle,but also pay attention to the sidelines on both sides.6.4 optimize the receiving and blocking formationIncrease the protection awareness among the players,especially the second pass players,after passing the ball,they should quickly participate in the formation of receiving and blocking the ball.In the training,it is required to form a complete receiving and blocking the ball formation for every defensive blocking the ball.
