Correlation of indicators of cerebral blood circulation withanthropometric dimensions in practically healthy young men ofectomorphic somatotype
In modern scientific literature, the vast majority of studies are devoted to the study of thefeatures of cerebral circulation in representatives of different age-sex groups, butstudies devoted to the constitutional features of cerebral hemodynamics in practicallyhealthy population are practically absent. The purpose of the work is to establishcorrelation of indicators of cerebral blood circulation with anthropo-somatotypologicalparameters of the body in practically healthy young men of Podillia with ectomorphicsomatotype. On the base of the research center of the National Pirogov MemorialMedical University, Vinnytsya conducted rheoencephalographic, anthropometric andsomatotypological studies of 24 practically healthy urban young men from the Podilliaregion of Ukraine of ectomorphic somatotype. The correlation analysis was performedusing Spearman nonparametric method in the licensed statistical package "Statistica6.1". In practically healthy young men of the ectomorphic somatotype, the followingmultiple correlations of cerebral blood flow parameters with constitutional parametersof the body are established: direct reliable (r from 0.41 to 0.52) and unreliable meanpower (r from 0.30 to 0.38) correlations of most amplitude indices with girth of the headand the largest length of the head, as well as the reverse, mostly unreliable (r from -0.30to -0.40), and a reliable average power (r from -0.41 to -0.53) correlations with most ofthe 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, mostlyunreliable, average strength (r from 0.33 to 0.38) correlations of the duration of thecardiac cycle and the time of the downward part of the rheogram with a half of the TSFFindices; direct, mostly unreliable, average strength (r from 0.30 to 0.37) correlations ofthe dicrotic index with a third of the indices of the TSFF and the endomorphic componentof the somatotype, as well as the inverse of the reliable (r from -0.40 to -0.58) andunreliable mean force (r from -0.30 to -0.40) correlations of the average speed of fastand slow blood filling with all total, half of the longitudinal body sizes, half of the WDEindexes, 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 andall the components of the body composition and the reverse, mostly reliable, averagestrength (r from -0.41 to -0.51) correlations of the index of tone of all arteries, the toneof the arteries of the large, as well as the middle and shallow diameters with more thanhalf of the indices of the TSFF and the endomorphic component somatotype. In theanalysis of correlations of rheoencephalogramms indicators with constitutionalparameters 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 numberof these indicators), indicators of component body composition (60.0%), WDE (45.0%),circumferential dimensions of the body (34.7%), cephalometric indices (34.3%) andTSFF (33.3%). The largest number, mostly inverse, of reliable and unreliable averagestrength correlations, was found for the derived indicators - with TSFF (47.2% of the total number of these indicators), somatotype components (29.2%), components ofbody mass (28.1%), total sizes body and WDE (25.0%); and, mostly direct, inaccurateaverage strength correlations, for time indicators was established - with cephalometricindices (28.6% of the total number of these indicators), TSFF (22.2%) and bodydiameters (14.3%).
