It should be noted that in recent decades the importance of strength training for increasing a special capacity in middle distance runners is not called into question. The use of training tools of strength orientation has become commonplace. The opinions of experts about the use of means of the group in training young athletes is not so clear. As a result the place of means of strength training in the structure of the training impact is causing some interest, which are developed by young runners on average distances and their impact on the growth of sportsmanship. Methodology and research organization. This study an attempt was made to get the information of interest, by interviewing experts. In this regard, respondents were presented a list of means of physical training recommended to use by runners on average distances on SISS (the stage of initial sports specialization). In consequence of this study an attempt was made to get the information of interest, by interviewing experts on this issue. The list represented a wide range of tools with different focus. The results of research. The results of the analysis have allowed identifying the most frequently used means and methods of strength training of middle distance runners aged 13-15 years. The results of the study indicate a fairly wide variety of tools used in the training process of young runners both in aerobic-anaerobic and anaerobic areas of power supply, and a narrow range of application of aerobic orientation. It should be noted that the detected ratio of training means should not mislead the experts, because it reflected only the preferences of respondents in relation to the diversification of exercises used with the purpose of improving the mechanisms of energy supply of muscular work. It should be noted that the most popular method used among trainers in strength training is a repeated-serial method and shock the least. As expected, the effects aimed at the development of strength endurance dominate in the structure of training loads of strength nature. At least significantly loads were mastered in means aimed at the development of speed-strength and the proper strength abilities. Conclusions. It is founded that accentuated effect on the muscle component of the athlete allows achieving more significant development of its motor capacity and a more efficient implementation of the latter in terms of competitive activity than when using traditional means of training.
