Correlation of indicators of cerebral blood circulation with anthropometric dimensions in practically healthy young men of ectomorphic somatotype

Abstract

In modern scientific literature, the vast majority of studies are devoted to the study of the features of cerebral circulation in representatives of different age-sex groups, but studies devoted to the constitutional features of cerebral hemodynamics in practically healthy population are practically absent. The purpose of the work is to establish correlation of indicators of cerebral blood circulation with anthropo-somatotypological parameters of the body in practically healthy young men of Podillia with ectomorphic somatotype. On the base of the research center of the National Pirogov Memorial Medical University, Vinnytsya conducted rheoencephalographic, anthropometric and somatotypological studies of 24 practically healthy urban young men from the Podillia region of Ukraine of ectomorphic somatotype. The correlation analysis was performed using Spearman nonparametric method in the licensed statistical package "Statistica 6.1". In practically healthy young men of the ectomorphic somatotype, the following multiple correlations of cerebral blood flow parameters with constitutional parameters of the body are established: direct reliable (r from 0.41 to 0.52) and unreliable mean power (r from 0.30 to 0.38) correlations of most amplitude indices with girth of the head and the largest length of the head, as well as the reverse, mostly unreliable (r from -0.30 to -0.40), and a reliable average power (r from -0.41 to -0.53) correlations with most of the total body size, half of the width distal epiphyses long tubular bones of the limbs (WDE), the majority of the circumference of the extremities, third indicators thickness of skin and fat folds (TSFF), performance component composition weight; direct, mostly unreliable, average strength (r from 0.33 to 0.38) correlations of the duration of the cardiac cycle and the time of the downward part of the rheogram with a half of the TSFF indices; direct, mostly unreliable, average strength (r from 0.30 to 0.37) correlations of the dicrotic index with a third of the indices of the TSFF and the endomorphic component of the somatotype, as well as the inverse of the reliable (r from -0.40 to -0.58) and unreliable mean force (r from -0.30 to -0.40) correlations of the average speed of fast and slow blood filling with all total, half of the longitudinal body sizes, half of the WDE indexes, the majority of circumferential body sizes, more than half the body diameters, most of the indicators of the TSFF, the endomorphic component of the somatotype and all the components of the body composition and the reverse, mostly reliable, average strength (r from -0.41 to -0.51) correlations of the index of tone of all arteries, the tone of the arteries of the large, as well as the middle and shallow diameters with more than half of the indices of the TSFF and the endomorphic component somatotype. In the analysis of correlations of rheoencephalogramms indicators with constitutional parameters of the body in practically healthy young men of the ectomorphic somatotype, the largest number, mostly inverse of reliable and unreliable mean strength correlations, was established for amplitude indices - with total body sizes (66.7% of the total number of these indicators), indicators of component body composition (60.0%), WDE (45.0%), circumferential dimensions of the body (34.7%), cephalometric indices (34.3%) and TSFF (33.3%). The largest number, mostly inverse, of reliable and unreliable average strength correlations, was found for the derived indicators - with TSFF (47.2% of the total number of these indicators), somatotype components (29.2%), components of body mass (28.1%), total sizes body and WDE (25.0%); and, mostly direct, inaccurate average strength correlations, for time indicators was established – with cephalometric indices (28.6% of the total number of these indicators), TSFF (22.2%) and body diameters (14.3%).
