Effects Of Modification Of Volleyball Competition On Defense

In 1895 America William. Morgan invented the sport of volleyball, from a game for entertainment purposes, the development of today has become one of the more people love sports. It is continuously destroy the old and establish the new rules, technology, continuous progress and development, volleyball was influenced by many people of all ages. As the saying goes "no rules no Cheng Fangyuan", is dedicated to the development of Volleyball Rules of volleyball. The volleyball each development period, can see, when some of the old rules have been unable to adapt to the development of a movement, the reforms will bring rules. During the continuous development of volleyball movement, rules were substantial changes, innovation and every modification will bring great change and volleyball, enhance the aesthetic game. Due to the continuous development and change rules of volleyball, add a lot of vitality and vigor to the volleyball, the volleyball match ornamental and the movement of social development to strengthen the adaptability. This paper will be significant modification effect on the rules of volleyball volleyball defense as the research object, through the literature material method, expert interview method, logic analysis method, the significant influence to analysis of the major rules of volleyball changes brought to the volleyball defense. Analysis of changes and content development of volleyball rules rules were mainly from the following volleyball on the site size, net height, ball specifications, receiving, defensive back block, etc., and points out the influence on the evolution of the volleyball defense produced. Studies have shown that:1,Volleyball net height change, mark rod shift, stimulated the blocking technology development, limiting the other side of the offensive line, reducing the pressure on the defensive back, effective jamming and undermine the other side to attack the organization.2,Each-serve-a-point rule implementation, service allows the OCS and other rules changes, promote the technical service of the raise, so there jump serve technique, the serve attack becomes strong, increasing the difficulty of receiving.3,T After the expansion of the service area, cancel service blocking the implementation of the rules, the digging action great changes have taken place, a former static brake "to predict a ground ball", now is to brake "edge to edge pre sentenced receiving", and through the game analysis of defensive players receiving in place rate of decline, the error rate is increased.4,To "free people" as the core of the defensive formation, the rear defender for the allocation of reasonable and effective. In the area of defense more difficult arrange the strongest team defensive ability of the free, in defensive pressure smaller regional arrangements with offensive capability is the strongest team, ensure the team’s defensive ability, to compensate for the lack of defense in the front row.According to the research results, combined with the significant effect of volleyball rules changes to the volleyball defense, I put forward the following suggestions.1, With blocking technology continuous development and innovation, in training should strengthen basic technical training of blockers, including blocking technology in pace, hand type basic movements, for example, sliding, cross step and step. To ensure the success rate of blocking, which is our anti anti back to create favorable conditions.2, The improvement of service requests us in daily training to strengthen docking service training, including the ball placement and direction judgment, reaction, mobile, and other training, for example, a mobile exercises, combined with ball-a practice, combine with practice.3, In the extension of the service area, the adjustment of the steps of the players in the training should be strengthened, the emphasis is strengthened, and the training of the hair pad technique is strengthened. The success rate of the service is ensured.. Aiming at the abolition of blocking serve technology, attention should be focused on the use of technology of passing and receiving, docking serve athletes put forward higher requirements.4, With the development and wide application of "free man" rules, each team in the world should pay more attention to the free man, so that it can give full play to its role in the game, the fierce competition and ornamental increase faster better promote the rapid development of volleyball.
