EVALUATION OF BODY COMPOSITION INFLUENCE ON STRESS RESISTANCE, ENDOTHELIAL FUNCTION AND WELLNESS INDICATORS ACCORDING...

Determining the influence of body composition on stress resistance, endothelial function and wellness and as a function of daily physical activity level and gender is of great medical-preventive importance․ The aim of this study was to analyse the influence of body composition on the stress resistance, endothelial function and wellness in different physical activity groups. A cross-sectional study was conducted with 2000 participants (829 men and 1171 women) aged 10-90 years. The Multiscan BS_OXI instrument was applied to measure the integral indicators․ For the study, statistical analysis was performed using Primer of Biostatistics version 4.03 by Stanton A. Glantz. Data analysis showed: (i) in the high physical activity group there was a significantly weak correlation between body composition and stress resistance in male (Rxy=0.24, p=0.000) and female (Rxy=0.28, p=0.0000) groups. In the case of low physical activity, a reliable weak correlation was registered only in the male group (ii) in the low physical activity group, there was a significant correlation between the body composition index and the change in the endothelium in the male (Rxy=0.4, p=0.000) and female group (Rxy=0.3, p=0.000) and in the group of participants with moderate physical activity, there was a significant correlation only in female group. (iii) In the high physical activity participant group, the correlation between body composition and wellness index was directly proportional in the male group (Rxy=0.33, p=0.000); in moderate and low physical activity, the correlation was directly proportional in the male and female groups. Thus, our study showed that the association of body composition with stress resistance, endothelial function and well-being depends on the level of physical activity and gender. However, further research is recommended to determine the influence of body composition ranges on various health indicators and to make recommendations and implement appropriate health and fitness programmes for the Armenian population, which should also focus on disease prevention.
