Annotation:  Parameters of physical development are one of the most important criteria of human health reflecting the influence of a wide range of endo- and exogenous factors. The aim of the work was to study the age and sex regularities of changes of body length and body segments in city school children aged from 7 to 17. The object of the research was pupils of general secondary schools of the city of Gomel aged 7–17 (1693 boys and 1757 girls) examined over 2010–2012. The program of the anthropometric study included measurement of body length and body segments (length of the trunk, arms, and legs). As a result of the analysis of the obtained data it has been established that the age dynamics of the studied parameters of the examined children depended on the constitutional features of their body-build. The maximum growth of body length and length of the trunk, arms, and legs was found in hypersomic boys and girls, then in mezosomic and the latest in leptosomic. The maximum growth of body length and body segments among girls of all the body types who start maturing earlier than boys are revealed at an earlier age in comparison with boys.
