A Comparative Study On The Technical Characteristics Between Strong And Weak Teams In High Level Women Competitions

Volleyball World Cup,Olympic volleyball match and Volleyball World Championship are three world-class volleyball events held by the International Volleyball Federation,with high level of teams and great influence.With the gradual development of volleyball,the intensity of the competition has increased,and the strength of Volleyball in various countries has been polarized.The traditional strong teams in the United States,Brazil,Russia and other Europe and the United States are still strong,and the Chinese women's volleyball team is also among the world's top teams under the leadership of coach Lang Ping.However,some countries in Africa and North and South America have made slow progress in Volleyball competitive strength.In order to solve the imbalance of strength,and to point out the direction of training and competition for coaches and athletes,this paper has carried out the corresponding research.In this paper,video observation,mathematical statistics and other methods are used to collect and analyze the data of the first three(strong team)and the last three(weak team)in 15 games of 51 games in 2019 women's Volleyball World Cup.Compare and analyze the similarities and differences in the technical application of the strong and weak teams,and analyze whether there are differences in the technical application of the strong and weak teams in the face of different levels of opponents.It is helpful for coaches and athletes to accurately grasp the development trend of volleyball technology and the law of winning.The main conclusions are as follows:1.There are significant differences in service types and drop points between the strong and weak teams,but the service effect is not significant;the strong teams prefer to use the high stability and powerful jumping floating ball technology;when playing with different teams,the strong teams are more stable,while the weak teams have significant differences in service drop points.2.The main attack is the main receiver,followed by the free man.There is no significant difference between the strong team and the weak team in terms of the receiving and serving players and the effect;when playing with different teams,the weak team shows significant difference in the receiving and serving effect due to different opponent levels,while the performance of the strong team fluctuates little.3.There are significant differences in attack types and effects between the strong and weak teams.The strong team has more "fast attack" than the weak team,and the weak team has more "back attack" than the strong team.The attack effect of the strong team is better than that of the weak team,and the attack effect is more effective.When playing with different teams,the strong and weak Teams show significant differences because of different opponent's level.4.The blocking effect of the strong team is better than that of the weak team,which can form the blocking formation of two or three people more timely and accurately.There are many times of blocking by single player in weak teams,and the blocking technology is weak.When playing with different teams,the blocking effect of strong and weak teams shows significant difference,and the blocking technology is not stable.5.The weak team is inferior to the strong team in passing effect,there issignificant difference between them;when playing with different teams,the strong team is stable,there is no significant difference,but the weak team shows the phenomenon that the passing error rate increases due to the strong opponent's level.In view of the above conclusion,the following suggestions are put forward: jump serve is the most important service mode of the world's strong teams,the weak teams should try their best to improve the stability and attack power of jump serve technology,and increase the accuracy of "serve to find people";the main attack is the main receiver,while improving the main attack receiving ability,the free man should expand the scope of receiving service,and reduce the pressure of the main attack receiving service To improve the efficiency of attack,the weak team should strengthen the cooperation of passing and attack and increase the times of fast attack;the weak team should consciously cultivate the blocking consciousness of the front row players,improve the ability of prediction and form the formation of multiple blocking formation in time and effectively;the weak team should ensure the effect of passing and improve the ability of the second setter to pass and handle the difficult ball.
