Comparative Study On The Service Characteristics Of Chinese Men's Volleyball And World Men's Volleyball

With the constant changes in the volleyball rules,the service of the ball from the hooks in the 1960 s to the extensive use of the ball in the 1990 s made the volleyball service reach a new level.The attacking ability not only broke the original balance of attack and defense,but also affected As a result of the game;the Chinese men's volleyball serve has always had a clear gap with the world's strong teams.Therefore,strengthening the attacking power of the serve has always been the goal of the Chinese men's volleyball team.This study uses the literature data method,expert interview method,comparative research method,observation method and mathematical statistics method to use the 2018 World Men's Volleyball Championship as the material.The Chinese team and the top six countries(including Poland,Brazil,USA,Serbia,Italy and the Russian team)conducted a total of 57 games for observation and statistical analysis and reached the following conclusions:1.In the game,the Chinese team uses the jumping ball technique to be higher than the jumping ball technique,while the top six teams use the jumping ball technique much higher than the jumping ball technique;the serve is an important technique that can directly score in the game,so Athletes should master a variety of tee techniques to improve the stability of the serve.2.The scores of the Chinese team's serve in the special serve are second pass,vice attack,main attack,and match;and the top six countries.The scores of the serve and the attack are higher than those of the Chinese team.The same turnover rate is also much higher than that of the Chinese team.The family's in-depth understanding of the concept of "spelling the ball" emphasizes the aggressiveness of serving in the usual training.3.After the game was interrupted,the Chinese team was less aggressive than the top six countries.The scores of the top six countries after the break were higher than those of the Chinese team,but the service failure rate of the top six countries was higher than that of the Chinese team;After the game was interrupted,the Chinese team's serve was more stable and not wrong,while the top six countries still pursued aggressiveness after the break,so they were higher than the Chinese team in scoring rate and turnover rate.4.The Chinese team and the top six teams serve in the six and eight districts of the middle field,and are located in the first and fifth districts at the junction of the end line and the transition line,and the seven and nine districts of the small slash.Less than six districts and eight districts.The author believes that the placement is too concentrated is that the teeing tactics are unreasonable in serving tactics and weaken the attacking attack.Therefore,it is possible to disperse the landing point,and appropriately use the tactical combination of the long line and the short line,the straight line and the diagonal line,appropriately control the serve strength,and increase the proportion of the ball before the net.5,the evolution of the competition rules,the original teeing area from 3 meters to 9 meters,in order to increase the attacking attack,to provide more choices for the serve.In the game,most of the serve of the Chinese team and the top six countries are the starting point of the service on the right side,and the service of the five areas and the six areas as the starting point is relatively small,so it is relatively single at the starting point of the selected service.
