The article is devoted to studies of the influence of physical training of different orientation on the physical development of athletes and wrestlers, which were related by age. With the help of anthropometric methods of research, it was found out that the indicators of body weight and body height were significantly higher in the group of wrestlers, but a year later they increased more significantly in the group of athletes. The volumetric parameters of the chest, except the rostrum of the chest, changed more during the year in the group of wrestlers. Higher values of indices of physical development and more pronounced dynamics of these indices during the year of playing sports in the group of wrestlers indicates a trend to strengthening their body constitution the influence of physical training aimed at the development of strength. In аthletes were identified low indices of physical development, which indicates a harmonious influence of the load orientation on the development of endurance, on the somatotype. The revealed directions of changes in the anthropometric indicators towards a more еxpressed increase in the transverse dimensions of the body of athletes who were engaged in freestyle wrestling and the longitudinal dimensions of the body of athletes engaged in athletics indicate the formation of the appropriate somatotype, which is favorable for the development of aerobic endurance in athletes and postural stability control рosture in wrestlers and, as a result, determines the sporting result. Thus, the revealed features of the dynamics of indicators of anthropometric parameters of the physical development of athletes of different sports specialization can be considered as a manifestation of the adaptation of the organism of athletes and wrestlers to a specific physical load. The results of the study of the dynamics of the morphological parameters of the physical development of athletes under the influence of physical load are of practical importance in coaching activities for increasing the efficiency of planning of the training and competition cycles in order to obtain high sports results and prevent injuries, states of overtraining and pathological conditions in athletes. In further studies, it is planned to determine the level of functional status and adaptation of the cardiovascular system of athletes of different specializations to aerobic and strength loads and a correlation analysis of the links between the level of the adaptive potential of the circulatory system and the level of sports results.
