INTERRELATIONS OF SOMATOMETRIC CHARACTERISTICS, HEMODYNAMIC AND CAPILLARY BLOOD FLOW INDICES IN YOUNG MALES OF THE MAGADAN REGION

Abstract

Goals. Revealing of physiological interrelations of the indicators of anthropometry, microhemocirculation, cardic hemo dynamic and physical development in young men- natives of the North. Methods. 160 young men aged 17-21, natives of the Magadan region in 1-2 generations took part in the study. Using a method of computer capillaroscopy morphometric structure of capillary and erythrocyte velocity at the nailfold capillaries was studied. The main somatometric indices, as well as, cardiovascular indices and integral rheogra-phy were measured. Results. Subjects' typing into groups was made according to capillary blood flow velocity. Interrelation was found between the variability of somatometric characteristics and the body functional state with capillary blood flow velocity. The analysis of the main cardiogeodynamic characteristics showed that in the group with a high capillary blood flow velocity the systolic and diastolic blood pressure values were significantly higher than in the group with a low velocity and consequently were significantly beyond the limits of normal for this age group in accordance to the recommendations of the All-Russian Scientific Society of Cardiology. Conclusions. The obtained results allow to put off capillary blood flow velocity as the informative typifying marker in cardiohemodynamics estimation. The efficiency of systemic blood circulation in subjects with higher capillary blood flow velocity is higher than in other groups. At the same time none of the groups had an optimal level of hemodynamics, which is due to adaptive physiological alternation of natives-Caucasoids of the Far North in comparison with higher blood pressure indices of their peers - inhabitants of the regions with more favorable climatic conditions.
