The problem of finding appropriate forms of structural organization of loads in annual cycle is becoming important for improvement of quality of young athletes training. This notion presupposes a stable order of combination of the parameters having different primary focus. The structure reflects the orderliness of connections in the system and provides its qualitative definiteness. Despite the fact that to solution of this problem in respect of training young middle distance runners has been paid sufficient attention, experts still have different views on forms of organization of impacts of strength character in annual cycle. With the aim of identifying optimum organization of impacts of strength character in the annual training cycle of runners aged 13-15 years on average distances, a survey was conducted among specialists (n = 21) who were asked to rank volumes of loads in annual cycle and rate them on a four-point scale depending on their value. The study of organization of loads of strength orientation was carried out in the framework of the analysis of their development at the stage of initial sports specialization on the basis of two parameters: dynamics of parameters of loads and coefficient of variation. The analysis allowed identifying two variants of their organization in the annual cycle: steady and variable.
