Objective of the study was to determination of the features of the influence of judo classes on physical development, physical fitness and functional indicators of individual biological systems of the body of children and adolescents.
Methods and structure of the study. The scientific work involved 100 children aged 9-12 years and 98 adolescents aged 13-17 years who are actively involved in judo wrestling at different stages of sports training (ENP, TE), in which indicators of the physical condition of study participants involved in different stages of sports training.
Results and conclusions. The overall positive effect of judo wrestling on the parameters under consideration has been established. The study also showed that each age period of a childs development has certain features of the functional and homeostatic status of the body, which can provoke characteristic damage in individual biological systems. This is of particular importance when a child is provided with additional physical activity in sports sections, since in conditions of active sports activities two processes occur simultaneously: the biological development of the body, determined genetically; the influence of external factors, namely sports training. Taking into account the provided features determines the stages of sports training and is extremely important for optimizing tactics and increasing the efficiency of the process of medical and biological support for athletes.

Keywords: judo, physical development, biological systems, physical fitness, athletes.
