Abstract

We performed the complex study of morphofunctional indicators of physical growth and puberty of schoolchildren of Gomel (1 693 boys and 1 757 girls) aged 7–17 with different body types. To assess the influence of social and biological factors on the development of morphofunctional indicators of physical development of schoolchildren, as well as the terms and rates of their puberty, we conducted the questioning of the parents. We studied the relation of the complex of social and biological factors with development of morphofunctional indicators of physical growth and puberty of schoolchildren with different somatotypes during the process of ontogenesis. The study revealed that biological factors affect the development of morphofunctional indicators of city schoolchildren with all somatotypes more than social factors.Social and biological factors affect the development of morphofunctional indicators in city boys and girls with lepto- and hypersomic somatotypes and do not affect the development of secondary sexual characteristics in city schoolchildren of both sex groups with different somatotypes.
