Abstract:The article presents the results of the spirographic survey of schoolchildren among the Khanty and residents of the Middle Ob region. The purpose of this work was inter-population analysis of features of respiratory system of schoolchildren of Khanty-Mansiysk Autonomous Okrug – Yugra at the age of 11–12 years. Measurement of respiratory function was carried using the hardware and software complex «Spiro-Spectrum». The results were analyzed using standard methods of mathematical statistics. All surveyed schoolchildren had 1-st and 2-nd health groups. According to the main anthropometric parameters the residents of the Middle Ob region were larger than the representatives of the indigenous nationality. All of the surveyed schoolchildren had reduced indicators of the IRV compared to expected values and indicators of the ERV were increased that contributes to the warming of air in the respiratory tract. This mechanism increases the metabolic cost of respiratory muscles and leads to a reduction of reserves of breath. Especially clearly this process is expressed among the Khanty schoolchildren and the girls among the residents of the Middle Ob region. High values of the minute pulmonary ventilation in a state of relative calm among schoolchildren of both population groups reflected increased oxygen requirement for child’s organism. High values of the PMV among girls achieved by increasing of the RR, it indicates about more intense activity of the apparatus of external respiration.
Key words: indigenous peoples, Khanty, schoolchildren, respiratory system.
