The purpose of the work: to determine ways to optimize the training load of young volleyball players of different ages on the direction and degree of coordination complexity. Research methodology: analysis and synthesis of scientific and methodical literature, program documents. Scientific novelty: a method of optimization of criteria for evaluation of coordination complexity of exercises in combination with determination of their volume and intensity has been developed. It reveals regularities of planning the development of motor qualities of young volleyball players of all ages on the basis of taking into account their growth rates. The reliability of the concept of training transmission, which is based on changing the relationship between motor qualities in age dynamics, has been proven. Findings. The presented method of optimization of criteria of assessment of coordination complexity of exercises in combination with determination of their volume and intensity will allow coaches to improve the management and control of training loads of young volleyball players and to avoid mistakes in their planning for a certain period. The presence of a growth rate of motor quality more than 3% indicates its sensitive period and the appropriateness of allocating up to 30% of the learning time for its improvement. The average level of activity is 2% of the growth, and it is recommended to allocate 20% of the school time per year. At a low level of activity, it is recommended to devote 10% of the time in the learning process to the development of this quality. The concept of «training transfer» is based on changing the relationship of motor qualities in age dynamics.
