Speed and strength training of volleyball players aged 13-14 - using the plyometric method

Relevance. Volleyball is a non-contact, combined sport, where each player performs a certain role. The motor actions of volleyball players consist in a variety of lightning-fast starts and accelerations, in a large number of explosive shock movements with a long, fast and almost continuous response to a changing environment, in jumping up to the maximum height. In turn, jumping ability largely determines the effectiveness of attacking and defensive motor actions of volleyball players. It is proved that a large percentage of winning points in the game is achieved in the fight over the net, so the jump training of volleyball players should be at a high level. Currently, there is a certain problem of the development of speed and strength training of young volleyball players, which remains one of the most relevant in theoretical and practical terms in modern volleyball. The solution to this problem is to increase the effectiveness of the training process, through the search and use of new techniques that allow you to lay the foundations for the development and improvement of specialized qualities of volleyball players. Research aim is to increase the speed and strength training of volleyball players aged 13-14 years with the use of the plyometric method in the training process. In the course of the study, it was found that the majority of volleyball players aged 13-14 years have a "satisfactory" level of speed and strength training. Research methods. To increase the level of speed and strength training of young volleyball players, it is proposed to use a set of specialized exercises for the development of explosive leg strength using the plyometric method. Using the proposed method, we managed to achieve statistically significant changes in the indicators for all testing procedures: long jump from a place (t=4.14 at P0, 001), jump up from a place (t=4,478 at P0,001), run 30 m (t=4.71 at P0,001), run 92 m (t=3.54 at P0,01), shuttle run (t=2.95 at P0,05). Conclusions. Thanks to the use of specialized exercises, using the plyometric method, it was significantly possible to shift the level of speed and strength training of volleyball players aged 13-14 years to the grades " good "and"excellent".
