We found out the sexual dimorphism in physical development indexes indicating formation of male or female type body during adolescence period. Boys differ from the girls by higher absolute and relative indexes of bone and muscle tissue and larger girths and distal sizes of the brachium, wrist, and breast. The portion of fat component is more in girls. The girths of the buttocks, thighs and pelvis diameter exceed the same indexes in boys.
