Comparative Analysis Of The Main Scoring Techniques Of Chinese Team And Matching Opponents In The 2017 U23 Men’s Volleyball World Championships

In August 2017,the third U23 World Men’s Volleyball Championship was held in Cairo,Egypt.The Chinese Youth Team won the eighth place for the first time,which was the best result of the Chinese team in the U23 World Championship.Achievement and hard training of athletes,coaches’guidance is inseparable,but throughout this World C.hampionship,the Chinese team’s starting block and strong team still have a certain distance.Through the methods of literature,interview,mathematical statistics and video observation,this paper mainly studies the attacking tactics,gains and losses of the seven matches against China in the World Championship,and draws the following conclusions:(1)The Chinese team members are short.Although the bounce ability is very good,the pitch height and the blocking height are relatively high,but it takes a long time to jump to the highest point,and it is not conducive to the second jump.This is true.There are higher requirements for judging the time of movement and take-off.This is also one of the reasons why the Chinese team’s blocking and offensive levels are not high.(2)When the Chinese team has no advantage in serving,the serve drop point is still more concentrated in the area where the middle free person is located.(3)Although the Chinese team’s serve is weaker than the opponent’s power,the stability of the serve is much better,and the mistakes are less than those of the opponent.In the choice of serving methods,due to the restrictions of the trial rules,the number of vigorous jumps this year is not many,most of them are fluttering.The Chinese team jumped the ball and broke the ball better than the opponent.The score was better than the opponent.However,the Chinese have adopted a large number of noo-powerful floating balls.(4)The Chinese team’s ability to score on the fastening ball is weak,and the ability to break through the other side’s blocking is not strong.The Chinese men’s volleyball level is very different from this opponent.Among them,the main offensive points are too concentrated on the main attack and the secondary attack,and the number of attacks received is much less than that of the opponent.The scoring rate of the main attack is the lowest,the score is much more than the opponent,and the score of the deputy attack and the collusion is less than the opponent.There are fewer changes in tactics,and most of the offensive ends are fast balls and strong attacks.The scoring rate of the Chinese men’s volleyball team is smaller than that of the opponent,and the scoring rate of the attack is similar.The defensive counterattack scoring rate is also similar,but the defensive score rate of the Chinese team is higher than that of other teams.In any case,the C.hinese team’s offensive level is not strong enough.(5)When the Chinese team has more blocks than its opponents,the blocking score is less than the opponent,and the score is more than the opponent.Whether it is a single person,a double person,a three-person blocking,or a number,a number three,and a number four blocking.The Chinese men’s volleyball team are slightly worse than their opponents in terms of blocking points.It shows that there is still a clear gap between the Chinese team’s blocking technology and its opponents.
