Age dynamic of physical condition changes in pre-school age girls, schoolgirls and students, living in conditions of Eastern Siberia

Purpose: to analyze dynamic of physical condition, considering sex (females) and age of the tested, living in region with unfavorable ecology. Material: we studied pre school age girls (n=1580, age 4–7 years). In the research we did not include children with chronic diseases, who were under observation. We tested schoolgirls (n=3211, age 7–17 years) and girl students (n=5827, age 17–21 years, 1–4 years of study. Girl students were divided into five age groups: from 17 to 21 years. All participants lived in conditions of Eastern Siberia (Irkutsk). This region is characterized by unfavorable ecology and climate geographic characteristics. Results: in dynamic of physical condition of pre-school girls, schoolgirls and students we marked out three substantial periods of it characteristics’ changes. Age 7-8 years is critical (transition from 1st to 2nd stage). The least values of these characteristics are found in older (after 17–18 years) ages. In students we observed relative stabilization of these indicators
