Development and contemporary problems of the periodization in sport training

This paper reviews the processes of formation and development of periodization in the theory of sport training, and attempts to identify problems on which future study should be focused. A major criticism of the classical periodization theory of Matvejev was the realities of top-level sports activities, which have now approached the mature stage and become uncoupled from the theory. These are problems that have been taken up as future topics in the classic theory, but have not been thoroughly solved. One is the problem of training charatteristics for each stage of athletic development, especially in the junior period and mature stage. Other problems have been related to training speciality due to classified sport events, especially speed-strength events and ball games. However, it cannot be ruled out that the development cycle of sport-form is an essential factor of periodization. Skepticism of analytical training study has been directed at the inseparable nature of exercise as basic training, being characterized by pleiotropy and polysemy. A new approach to solving this has been emerging in training studies, which discuss the effects of physiological load in training exercises specialized for technical dnd tactical training. The primary problem in future training studies will be the structuring of Sports training and the competition system as a versatile preparation process for the improvement and stability of sports performances. In addition, integration of conditions and technical-tactical training will be indispensable.
