Some aspects of the use of modeling methods in the system of training highly skilled volleyball players.

The approaches of using modeling methods in the training process and competitive activity of high-qualified volleyball players are devoted in the article. The leading experts from European countries are considering the training process as the development of athlete's behavior models. Thus, using modeling methods for improving the training system for athletes in volleyball is a promising one. The purpose of the research is to theoretically substantiate using modeling methods in the training and competition process of highly qualified volleyball players. The following research methods were used: theoretical analysis of special literature, sociological methods, pedagogical observation, video shooting of competing activities, methods of mathematical statistics. We were interviewing leading volleyball trainers, analyzing games, working out scientific literature, which allowed obtaining some aspects of using modeling methods in the training process and competitive activity of high-qualified volleyball teams. Results. The creation of a multi-year volleyball training program is based on the normative tasks at different stages and it involves the development of training and competitive process models for their implementation. The models of competitive activity are fundamental for construction the multi-year training process. Informative criterias of competitive activity are the effectiveness of technical and tactical actions and player activity. Model requirements for the quality of technical and tactical actions in the process of competitive activity of volleyball players (forwards) were presented. The attack model from the second pass of back line setter is provided by qualitative first dig. Conclusions. Players should have unexpected "game moves" and various mini-models of technical and tactical actions to achieve high-level volleyball game and reduce the risk of uncertain situations in the process of competitive activity
