ABSTRACT Aim: To investigate the influence of judo club activities on the physical development indicators of 16-17-year-old young males. Materials and Methods: The research, conducted in 2022-2024, involved 54 young males aged 16-17, who were divided into experimental (EG) and control (CG) groups of 27 each. The physical development was assessed by body weight, hand dynamometry, lung capacity, heart rate, and blood pressure indicators. Cooper, Rufier, Stange, Genchi, vital, strength, body weight, Robinson, and maximum oxygen consumption indices were calculated. Results: The positive influence of judo club activities on the physical development of 16-17-year-old young males was revealed: all studied indicators sig nificantly improved in the EG young males during the experiment. Judo training sessions had the most effective impact on the indicators characterizing the development of the muscular system and the level of strength qualities. At the end of the experiment, young males of the EG showed significantly better physical development than the CG representatives in terms of strength index (by 6.33 %), static endurance of stronger (by 2.07 s) and weaker (2.03 s) hands. According to the indicators characterizing the state of cardiovascular and respiratory systems, the indicators of young males of both groups were significantly the same. Conclusions: It has been established that judo club activities, which were conducted taking into account the age characteristics of 16-17-year-old young males, create the most favorable conditions for the harmonious physical development of boys, promoting their health and preparing them for future educational and professional activities.
