Depending on the sport and the period of the training sessions, the subjects were divided into 3 groups: children with training period up to 1 year (1 group - control group), children engaged in sports for 1-2 years (group 2) and children engaged in sports for 3 and more years (3rd group). Somatometric and calculation methods were used. Results: normal values of body mass index in female and male enlarged with training irrespective of sport. Youth athletes engaged in sport 3 and more years were characterized by a normal ratio of growth and body weight.
