The study is based on anthropometrical measuring of limbs and their segments in children and adolescents at the age of 7-17. Age changes in limb proportions and their changeability have been studied. Throughout the growth period, lower limb proportions in boys are bigger than those in girls. The relative lower limb length in both sexes is the biggest at the age of 14. The growth of upper limb segments goes in almost the same way in children of both sexes. In the beginning of the age period in both boys and girls, lower limbs and their segments are characterized with a more intensive growth compared to upper limbs, as this characteristic in boys continues to the end of the explored time period, but in girls - up to 15 years. Limbs and their segments practically reach their definitive values at the age of 15-16 in girls, and in boys they keep growing after this age, though less intensively. .
