Abstract

The paper analysed key haemodynamic and anthropometric parameters of high school students living in Vladikavkaz taking into account sex-related differences and the adaptive potential of the circulatory system. The anthropometric parameters of most schoolchildren were within the norm, but the waist-to-height ratio was lower in boys than in girls, which corresponded to a higher content of abdominal fat in the latter. It was found that, with decreased adaptive reserves by the end of the school year, the adaptive potential in most schoolchildren (68 %) could be classified as adaptive stress (2.23 [2.03; 2.39] points). The body’s functional reserves in boys were mobilized primarily through an increase in systolic pressure (125.0 [118.0; 130.5] mmHg), while in girls, in heart rate (up to 87.15 [82.57; 96.97] bpm).
