Research On The Effect Of The Back Row Attack Of The Top Eight Men’s Volleyball Teams In The Tokyo Olympic Games

As an attack mode with important tactical significance,the back-row attack technique becomes more and more important in volleyball match.The appearance of the back row attack has provided a change for the volleyball attack.the original limitation of the volleyball attack tactical system has been broken,and the multi-dimensional attack tactics of the front and back row have been formed in the modern volleyball.In order to analyze and discuss the technical and tactical characteristics of the world high-level men’s volleyball back row attack,so as to provide a more sufficient theoretical basis for our team to carry on the corresponding tactical improvement and innovation.This paper makes an in-depth study on the use of the back row attack of the top eight men’s volleyball teams in Tokyo Olympic Games by comprehensive use of various methods,including literature,video observation,mathematical statistics and logical analysis.Through the research,the following conclusions are drawn:1.In the eight elite men’s volleyball teams of Tokyo Olympic Games,there are significant differences in height,weight and spike height between the main back row offensive players and some players of Japanese men’s volleyball teams;There is a significant difference in the height and spike height of the Italian and Argentine attackers.All the non-technical indexes of the receiving players are higher than those of the main attacking players and there is a significant difference between the receiving players and the main attacking players in spike height.2.All eight teams have played between 15 and 25 percent of their back row offense.The back row offense scored at a slightly higher rate than the overall offense.3.In this game,the back-row attack of position 5 was basically abandoned by each team.The back-row attack of position 1 is used more than the back-row attack of position 6,but the back-row attack of position 6 is more effective.4.The use of back-row attack in the eight teams is mainly concentrated in the receiving attack system,while the use of back-row attack in the counter-attack system is relatively low.The attack effect of the back row attack in the receiving attack system is better than that of the counter attack system.5.In this match,the use of back row attack with front row attack cover accounted for 68.66% of the total back row attack.In the case of front line offensive cover,the back-row attack of position 6 and position 1 is more balanced.But in no-screen situations,the distribution of the back row is completely skewed in favor of the back-row attack of position 1.There is a correlation between the rank of back-row offense in no-screen situations and the final game rank.6.The top eight teams average 1.06 seconds of pass time in the back row.There is a significant difference in passing time between the second and third downs.There are also obvious differences in the passing time between the back row attack in the receiving system and the back row attack in the counter attack system.Based on the above conclusions,we make the following recommendations:1.Considering the characteristics of back-row attack,emphasis should be placed on the development of muscle strength and muscle circumference of athletes while emphasizing the large size of athletes,so as to better play back-row attack and other techniques.In the athletes’ training arrangement,it is recommended to adjust according to the special position characteristics of athletes in different positions.2.In peacetime training,the importance of back-row attack should be emphasized,and the setter should develop the consciousness of actively organizing back-row attack,and pay attention to improving the quantity of back-row attack,but also to ensure the quality of back-row attack.3.Improve the ability of the the back-row attack of position 1 to break through the block,and organize the back-row attack of position 6 in the case of cover.Although the back-row attack of position 5 has been abandoned in the men’s volleyball competition in this Olympic Games,it does not mean that the back four attack is completely useless,and can be used according to the team’s own tactical characteristics.4.Increase the use frequency of back-row attack in the receiving attack system.The back-row attack in the anti-return system should try to avoid the organization under the condition of poor defensive pin-up quality and uneven offensive formation.5.Increase the frequency of use of back row attack with front row attack cover.Considering the high frequency of the use of the back-row attack of position 1 without cover,we can arrange targeted exercises for the strong attack breaking ability of the the back-row attack of position 1 in the training.6.Shorten the passing time of back-row attack through training,especially in the case of cover,so as to get better attacking effect.
