ОБҐРУНТУВАННЯ СИСТЕМИ ПІДГОТОВКИ БІГУНІВ НА СЕРЕДНІ ДИСТАНЦІЇ В СУЧАСНИХ УМОВА

Relevance. The question of improvement of the training process of sportsmen is important at different stages of preparation. The construction of the training process of sportsmen specialising in middle-distance running, taking into account the importance of high-speed and power loads, is not properly reflected in the theory and methods of sports training. In modern conditions experts discuss the correlation and efficiency of general and special physical training. A small number of works, which mainly analyse physical training, relate only to the training of highly qualified athletes. Therefore, the optimal construction of the training process of athletes, taking into account their functional state, is becoming increasingly important. The study of this problem is of practical and scientific interest. The purpose of the research is to develop and theoretically substantiate the content of training work of 800 m runners with qualification of I adult category in different types of microcycles of the preparatory period. Research methods: the analysis of scientific and methodical literature, pedagogical supervision. Results. The theoretical and methodological aspects of physical training of athletes specialising in middle distance running are considered. The physical training of middle distance runners is a determining factor in the training process aimed at developing the necessary physical qualities. The article analyses the system of training middle distance runners in modern conditions. The content of microcycles of middle distance runners at different stages of training is described. It is emphasised that strength and speed-power qualities (increase in muscle mass and strength, increase in explosive power and speed), development of aerobic and anaerobic endurance, flexibility and coordination abilities are the leading qualities for middle distance runners. This discipline synthesises speed characteristics and endurance, because it requires both maximum speed and a significant resource of special endurance. Conclusions. The scientific sources on the training of athletes specialising in 800m run were analysed in order to determine the differences in the training systems of specialists from different countries. It is determined that with the effective implementation of the means of improving high- speed endurance in the training process, it is possible to improve sportsmanship.
