Overweight and obesity are among the most complex medical and social problems. Excess adipose tissue is associated with an increased risk and rapid development of cardiovascular diseases, and in particular among young adults. The aim of the study was to determine the functional state of the cardiovascular system in young people depending on the body weight. Ninety six participants of both sexes aged 18-25 were examined. Determined of height, body weight, waist circumference (WC) and thighs circumference (TC) and their ratio. Given the body mass index (BMI) they were divided into 3 groups: the control group included those with BMI 18.50-24.99 kg/m2 ; the group with the subjects having increased body weight with a BMI 25.00-29.99 kg/m2 , and the group of the subjects with class I obesity and BMI 30.00-34.99 kg/m2 . We determined indicators of heart rate, systolic and diastolic blood pressure at rest and following the exercise stress test, calculated pulse and mean hemodynamic pressure indicators, Robinson index. The results obtained were statistically processed. The study demonstrates a significant increase in the indicators reflecting the functional status of the cardiovascular system in the overweight participants and the individuals with the class I obesity at rest and after the exercise stress test that is confirmed with the mostly positive medium correlations between anthropometric indicators and functional activity indicators of the cardiovascular system in the individuals of the study groups. Significantly elevated Robinson’s index in the overweight male subjects and in the individuals of both sexes with class I obesity indicates a lack of functionality of the cardiovascular system, reduced energy metabolism and efficiency of the cardiovascular system. The resulting changes require physiological correction by modifying the lifestyle – reducing the caloric content of the diet and increasing the level of physical activity to prevent the intensification of pathological changes and the development of cardiovascular system diseases.
