| In recent years,the development of gas volleyball has developed rapidly.Various types of gas volleyball competitions are in full swing throughout the country.More and more volleyball enthusiasts are participating in the gas volleyball competition.With the continuous improvement of competition,the various technologies of athletes The requirements are getting higher and higher,but the lack of theoretical foundation limits the development of gas volleyball.It coincides with the 2018 gas volleyball project joining the 14 th Games of Gansu Province for the first time.The teams from all over the province are on June 30,2018.On July 1st,the competition was held in Yongjing County.The team that entered the semi-finals represented the highest level of Gansu provincial volleyball.The author selected the competition between the men's semi-finals in this competition to analyze and draw relevant conclusions.In order to make up for the scientific research gap in the offensive technical effects of gas volleyball.This article mainly uses the literature data method,video statistics method,mathematical statistics method and logic analysis method to collect statistics on the six games of the men's semi-final team in the gas volleyball project of the 14 th Gansu Province in 2018.The effect of the three offensive techniques of smashing and blocking is analyzed,and reasonable suggestions are put forward to improve the level of competition of each team and provide a theoretical basis for the development of qi volleyball.The research conclusions show that in addition to the serve effect,except for the Lanzhou City Association team,which is mainly based on the standing service,the other teams are mainly based on the combination of the strong serve and the stand-up serve.The strong jump is the most offensive and direct.The scoring rate and the attack rate are the highest,but the turnover rate is higher;the standing serve has the strongest stability,and the direct scoring rate and the attack rate are lower;the hook serve is generally effective in this competition,because the air volleyball venue is smaller.The quality of the sphere is lighter.The floating ball commonly seen in hard volleyball appears less frequently in its volleyball game.It is easy to cause the out of bounds to lose points.The ball is swung forward and the ball speed is faster.The drop point is close to the front field and the defender is Caused a big impact.In terms of smashing,due to the low rate of passing,the teams used the strong smashing as the main scoring method,forming fewer tactical attacks and having a single offensive tactic due to the short length of the volleyball volley and the limitation of the offensive line.The offensive effect is better.In terms of blockage,the effect of the three-blocker is better than that of the double block and the single block.Due to the low net height of the volleyball and the short length of the net,it is easy to form a three-block block and a double block.The main reason for not forming a three-person block is to move.Slower speed and multiple rounds of continuous blocking ability.Based on the above results,the following suggestions are made: establish a service attack system with a strong jump serve as the core,strengthen the training of the serve line and the drop point,ensure the attacking attack while improving the stability;master a variety of serve methods to disrupt the opponent's serve.Make full use of the network leader to develop effective smashing offensive tactics according to the characteristics of each team;strengthen the training of the moving speed of the blocking net,improve the consciousness of continuously forming three blocks in multiple rounds;improve the psychological quality of the players to ensure the proper level of offensive skills in the game And offensive effects. |
