Sinigovets I. Speed-power training of volleyball players of 15 - 17 years in view of game role.

The dissertation is devoted to perfection of training process of volleyball players of 15 - 17 years on the basis of differentiation of game role. The following research methods: the analysis of references, pedagogical supervision, pedagogical experiment, pedagogical tests, anthropometry, photometry, myotonometry, mathematical statistics were used during the working, the parameters of foot's support - spring properties were measured by "Big Foot" software 362 volleyball players in the age of 15 - 17 years have participated in researches. Statistically significant distinctions of investigated parameters between volleyball players of various game role have been determined on the basis of preliminary researches. Researches have given the opportunity to determine the quantitative characteristics of techniques performance for the first time, and also to define the most important factors describing a condition of separate systems of an organism of volleyball players of various game roles. The received data have allowed to develop the program of physical training, and also the modeling characteristics and estimated scales for each game role of volleyball players. The basic research results have found the practical application in training process of volleyball players. The offered program for perfection of physical preparation has shown the high efficiency. It proved statistically significant changes of speed-power parameters between control and experimental group.
