Comparison And Analysis Of The Effect Of The Technical Application Of The Four Strong Libero Players Of The Women's Volleyball Team In The Thirty-first Olympic Games

In 1999,the libero player rule was formally implemented,and the libero player guaranteed the success rate of the transmission and defense,and increased the round of competition and the excellence of the competition;Secondly,the appearance of libero player can relieve the pressure of the attacking players,so that the attacking players can take proper rest and conserve energy;Once again,when the two-pass movement is not in place,the free man can replace the attack of the second pass and save the energy for the second pass;In the end,the emergence of libero player has completely liberated the two passes.In the current volleyball match,the relay has become a strong point of attack,so that the offensive point of the party is increased and the pressure of the main attack is shared.With an understanding of the principles of libero player,set up to receive free artificial core formation and defensive formation,give full play to the role of the free and is flexible and accurate predictions and concentration,actively preparing for the attack.It is base on that data obtained from the four strong competition in Rio in 2016,and adopts the literature data method,the video observation method,the contrastive analysis method and the mathematical statistics method,and analyzes the shortcoming and advantages of the libero players application in the competition in order to search for the direction of the future efforts.The research draws the following conclusions:1?The modern volleyball is developing towards the direction of the strong attack,the power of serving and smash is getting bigger and bigger.In order to ensure the stability and success rate of the service,the libero player in the back line needs strong anti shock and muscle strength,so the weight has a great influence on the competitive ability of the free man.2?In the serve,the international powers three men who serve at the core of the libero players serve,and not only the team player,but also the best of the team,and the ability to play the front line,the ball rate in the back of the line,and to the most extent,to the libero player,which is used by the international powers.3?On the defense,use �on the side� defense,the libero player and the back of the back to the defensive line,the libero player defends the number five position of the attack route,the success rate of the defense,and the attack route of the team.This defensive formation was adopted by the powerful women's volleyball team.4?In a tapping system,the mode of finding a person looking for a point is used,the libero player needs to help the main stone bear the pressure,the range of the ball contact is increased,so that the total number of passes is higher than that of the main tapping,but the reach rate is lower than that of the main tapping.5?In defence of the attack,attack,push system,replacing the back had a libero player,the probability of the ball is high,high success rate,providing plenty of time to other players attack,libero player in a core position in terms of defense.6?If the libero player is in charge of adjusting the pass and organizing the offensive,the coordinate offensive way of the free person and the player will not be very much,and the offensive will be focused on the position 2 and 4,the attack point will be too single,and the offensive will be easy to be exposed,and the difficulty of the attacking team will be increased.
