IMPROVEMENT OF CARDIAC FUNCTION AFTER WEIGHT LOSS PROGRAM AMONG YOUNG WOMEN

Abstract

The aim: To determine the difference between body composition and hemodynamics indices at baseline and after the weight loss program. Materials and methods: The subject of this study was 13 young women. The weight and body composition were measured by the bio-impedance method. Hemodynamics indices were measured by the method of the thoracic rheography. The measurement of body composition and indices of hemodynamics were performed at the beginning of the weight loss program and 2 months later. The participants underwent 45 minutes per day of moderate-intensity physical activity 3 times a week. Results: The percentage of body fat decreased in 3.9±0.37% from baseline (p=0.01) and the level of visceral fat - 1.54±0.14 units (p=0.001) respectively. Indices of hemodynamics were improved after the weight loss program. Firstly, the index of cardiac output was reduced in 1.43±1.09 l/min (p=0.019) after 2 months of the weight loss program. Secondly, the indices of peripheral resistance also have been improved. Moreover, the index of workload of left ventricle has decreased from 3.56 to 2.7 kg/m/m2 (p=0.035). Conclusions: Our results demonstrated the improvement of indices of hemodynamics due to the normalization of body composition among young women after weight loss program.
