Promising areas research work and organizational and managerial improvement sports reserve training systems

Relevance. In the works of modern leading scientists and managers of sports, the need for modernization of the children's and youth sports and sports movement is expressed on the basis of the primary realization of the target aspirations of improving the effectiveness of the training of the sports reserve for sports teams. The scientific postulate, approved in the physical culture and sports environment, is the view that children's and youth sports is the basic stage of the formation of readiness for competitive activity of persons undergoing sports training. An objective indicator of the effectiveness of the sports reserve training system is the criterion of the effectiveness of children and young men at international competitions. As factual data, for example, the results of the successful performance of Russian athletes (the age of participants in the competition is 15-18 years) are given at the third Summer Youth Olympic Games, Buenos Aires 2018 (first place in the unofficial team competition, a total of 59 medals, of which 29 gold, 18 silver, 12 bronze), and the third Winter Youth Olympic Games, Lausanne 2020 (first place in the unofficial team competition, a total of 27 medals, of which 9 gold, 10 silver, 8 bronze). However, these data are formally statistical. The purpose of the study We set the task, using scientific research methods, to prove the validity of the hypothesis that results in junior and youth age become significant when predicting results at the stage of higher sports achievements. Research methods. A retrospective analysis of the protocols of participation in competitions of junior and adult athletes in the Championships and Championships of Europe and the World in Athletics for the period 1991-2019 was carried out . This period reflects the active period of development of Russian athletics, after which there were restrictions on the participation of our athletes (juniors, youth and adults) in European and international competitions (European Championship 2016, 2018; European Championship U20 U23 2017, 2019, World Championship 2017, 2019; The U20 World Championship 2016, 2018) in connection with the personal admission of athletes to the competition. To process the data obtained, the method of statistical processing of the variational series of measurements and correlation analysis were used. Results: Statistical retrospective research methods have confirmed the connection between the success of the performance of highly qualified athletes in the European and World Championships from the success of their previous performance in the rank of juniors and young athletes on the European and world stage. Conclusions: The hypothesis is confirmed that the performance of young athletes (juniors) largely determines the subsequent success in the performances of national track and field teams in the European and world arena.
