BODY COMPOSITION OF YOUNG WOMEN WITH DIFFERENT AGING RATES
The aim of the study was to research the relationship between the indicators of the body composition and the rate of aging in women of the adolescent period. The study involved 383 female students aged 19-21 years. The main anthropometric indicators were recorded according to generally accepted methods. The body composition was studied with the bioimpedance method. The biological age and the rate of aging were calculated using of A.G. Gorelkin and B.B. Pinkhasov formulas. It was revealed that in 19.8% of young women had a correspondence between the biological and calendar age, 52.2% - a lower aging rate, 28.0% - an accelerated aging rate. The content of the main body components differed statistically significantly between the groups of women with different rates of aging. Aging rate increase factor affected the relative increase in the content of fat mass and lower relative content of the lean, skeletal muscle and active cell mass. An increased content of fat mass was observed in 2.0% of women with a low, 14.5% normal and 63% accelerated aging rate. Low values of the relative skeletal muscle mass were noted in 3.6% of women with a low, 10.9% with normal and 85.5% with accelerated aging rate. The results of the correlation analysis showed that there is a statistically significant relationship between the aging rate and the content of all body components. Aging rate increase was associated with an increase in the relative fat mass and a decrease in skeletal muscle and active cell masses.
