volleyball game is more diversified and changeable,and in terms of technology,the competitive volleyball game is also adapted and developed in the direction of all-round,multi-change,diversified,rapid and agile tactical development.After the 2016 Olympics in London,the next Olympic cycle,the world woman’s volleyball game and some of the basic tactics has successively entered a new phase,mainly in Asia such as China,the United States,Japan,Brazil,America fast agile and changeful style features of high level teams and advocating high accuracy power play Italy,Serbia,Dutch and other European teams are constantly fusion,the characteristics of the world woman’s volleyball team is moving into the trend of higher,faster,stronger development.In other words,at the present stage of the world’s strong woman’s volleyball team in the pursuit of all-round development of the style of play,the demand for the deputy offensive player is also higher and higher,the deputy offensive player’s technical and tactical position in the team has become self-evident importance,the performance of the deputy offensive player has even become the influence of the competition.In competitive volleyball,studies on Middle blockers at home and abroad generally focus on the techniques and tactics of individuals or teammates,and most of the studies focus on Middle blockers in man’s volleyball.However,according to the current development of woman’s volleyball,especially for the rapid and changeable Asian teams in the secondary attack role,the proportion of the attack has been less than before.However,the secondary attack in the team to assume the role of serve,block and fast attack,the importance is more prominent,the technical and tactical position is more prominent,in the whole team to play a more specific role.Based on the FIVB world woman’s volleyball championship in 2018 as the carrier,through literature,mathematical statistics method,expert interview method,system analysis,comparative analysis and logical reasoning method,such as the FIVB woman’s volleyball tournament champion Serbia in 2018 woman’s volleyball team and Italian woman’s volleyball team and the 2nd runner-up Chinese woman’s volleyball team consists of three blocker as the main research object,the related good blocker in the woman’s volleyball technology and tactics to study the characteristics and the contribution rate,analysis the world woman’s volleyball team of outstanding blocker technique features in the game and the contribution rate,And conclude that the world woman’s volleyball team good blocker in the role of team tactics system,in order to optimize the technology and tactics of the Chinese woman’s volleyball blocker system and back-up athletes had provide valuable theoretical basis for select material,for Chinese woman’s volleyball team to prepare for the 2020 Tokyo Olympics in blocker has some specific advice on tactics.The results show that :1.The serve of the world’s excellent woman’s volleyball sideline players is dominated by the jump,serve and float,with solid basic skills.The serve is a threat to the first pass of the opponent,which can often promote the use of the blocking and defending tactics of the team.2.The average spiking height of the toss of the world’s top woman’s volleyball team is higher than that of the spikers.Influenced by the tactical requirements,the vice-spiking spiking has the characteristics of high spiking point,fast speed and variable technique;3.The average blocking height of the excellent woman’s volleyball players in the world is higher,and most of them are better than that of the spikers.The blocking function of the players is mainly responsible for the players,which ensures the arrangement requirements and application effect of the blocking tactics.4,In the world woman’s volleyball team blocker is visible on the location selection of distribution in attack and each blocker features relatively bright,cooperate with toss tactical arrangement is relatively less specific,change,two points attack had mainly toss fly back behind the tactics,such as poor position is complementary,three points attackl had mainly toss front of rapid spike,cooperate with hanging tactics,etc.;5.Based on the research on the blocking tactics of some countries’ excellent vice-spikers in the 2018woman’s volleyball world championship,it can be concluded that the world’s excellent vice-spikers are dominated by double blockers and supplemented by three blockers.Seven of the top ten players in the blocking score of this world championship are the players in the vice-attack,which highlights the importance of the vice-attack players in shoulding the team’s blocking responsibility and the execution of blocking tactics.6.The Chinese woman’s volleyball sideline players have strong ability to involve and score.The attacking points of the Chinese woman’s volleyball team are relatively scattered.Because of the strong offensive ability of the two wings,the European and American teams participate in the attack of the number of times is relatively less,but because of their own strong ability,so the scoring ability is more outstanding,scoring efficiency is higher;7,Because the world’s excellent woman’s volleyball of two points attack is more closely marked,tactical intention exposed,break through the other side block score more difficult,the world’s excellent woman’s volleyball team of three points attack is more covert better,attack is more sudden,the scoring rate is often higher;8,the world’s outstanding woman’s volleyball sidesaddle serve,block and spike three indicators of the contribution rate of sidesaddle,the world’s outstanding woman’s volleyball sidesaddle score ability is strong,there is a certain role of the role of a major contribution to the team.In the context of the development of competitive volleyball,in the evaluation and selection of reserve talents,secondary players should not only focus on the height of the players,but also on the ability to jump quickly,arm span and reading the competition.The use of tactics such as close body quick,back flat fast,position difference and looping should be more abundant and hidden.The attacking rhythm should be faster.The ability of handling "half in position" and "half high ball" should be improved to improve the score rate and contribution rate of the players in the secondary attack.Strengthen the core strength training of the vice-attackers,cooperate with the accurate prediction to complete the double block and the three-man block under a certain moving speed and height,and use reasonable blocking hands such as pressure and support according to the different timing of the position to improve the blocking effect. |
