Abstract

Purpose: to study dependence of indicators of efficiency and quality of a power serve in jump from the increase in accuracy of its performance.

Material & Methods: pedagogical observations, mathematical methods of processing of results.

Results: the comparative analysis of these indicators of the group of volleyball players of series of plays of the superiority of teams of the highest league, which took place before and after the corresponding experiments, connected with use of the offered by the author technique of increase in accuracy of a serve, is carried out. The assessment of statistical reliability of distinctions between results of the comparative analysis of the corresponding indicators of efficiency is executed by means of the criterion of Student.

Conclusions: the reliable changes in values of the corresponding indicators of efficiency of a serve testify to the effectiveness of the offered technique, and consequently, about the correctness of its use during the training process.
