THE INFLUENCE OF THE BALL SERVE IN VOLLEYBALL ON THE RESULT OF THE MATCH
In this study, the influence of the ball serve effectiveness indicator on the final result in volleyball matches is identified. The ball serve has a number of differences from other technical elements in volleyball, since the serve is the only element that is performed individually in team sports, and the organization of the opponent's attack and defensive actions of the serving team depend on it. The authors give specific examples of the analysis of seven games in the final of the Championship the Association of Student Sports Clubs of Russia and the cup of the Student Volleyball Association, where the actions of players on the serve led to positive and negative consequences. The definition of such an indicator as "the serve effectiveness" is given, which can be studied using the information and statistical system "Volleyball analyzer". As a result of the study, it was revealed that the Pearson coefficient is equal to 0,6, which indicates an average close correlation between the statistical data on the serve and final results of the match. Thus, when organizing the training process of volleyball players, it is necessary to increase the amount of work on the ball serve, because it serves as one of the means of the active offense, with which you can gain a point or disrupt the organization of offensive actions of the opponent, which will allow you to gain an advantage in the score and more likely to achieve a high sports result.
