Evaluation of morpho-physiological characteristics of students living in northern conditions

Abstract:

The study focused on the physical development indicators in younger teens aged 11–12 (Group 1) and 13–14 (Group 2) living in northern conditions (Surgut, Russia). The data was collected and processed in spring from February through March 2020. The physical development, the functional state of the cardiovascular system, and the functional body reserves were assessed by anthropometric and hemodynamic indicators. It was found that physical development was harmonious in the majority of examined teenagers. Among elder teenagers, more boys had good physical development, while more elder girls showed signs of asthenization. Hemodynamic parameters reflected the improved functioning of the cardiovascular system in relation to age. The integrative indicators of heart rate hemodynamics and arterial blood pressure were above the age-sex norm, which indicates stress on the vital systems. The adaptation reserves in teenagers of both groups were reduced during the spring period: 47–66 % of teenagers in Group 1 and 57–68 % of teenagers in Group 2 demonstrated unsatisfactory adaptation indicators.
