Features of indicators of crus rheogram in practically healthy teenagers of different somatotypes

Abstract

Norms for assessing the functional state of the peripheral vascular system are developed, as a rule, without regard to age, gender and somatotype. The purpose of the study is to establish features of the indicators of crus rheogram in practically healthy girls and boys of different somatotypes, residents of the Podillia region of Ukraine. Rheographic indicators of the cohort of 108 practically healthy girls aged from 12 to 15 years old and 103 boys aged from 13 to 16 years and 103, urban residents of the Podillia region of Ukraine, were determined using a cardiology computer diagnostic complex. Anthropometric survey was conducted in accordance with the scheme of V. V. Bunak (1941). To evaluate the somatotype of adolescents, the mathematical scheme of J. Carter and B. Heath (1990) was used. The statistical processing of the obtained results was carried out in the license package "Statistica 5.5" using nonparametric methods for evaluating the obtained results. As a result of the research, it was found that most of the amplitudes and some of the derived indicators of the crus rheogram in girls of the mesomorphic somatotype are significantly lower or tend to be smaller than those of other somatotypes, while the time of the rising part of the rheogram and the time of slow blood filling are significantly higher than at representatives of an ectomorphic somatotype. In boys of mesomorphic somatotype, the basic impedance and amplitude of the systolic wave and the average speed of fast and slow blood flow of the rheogram are significantly lower or tend to be lower than those of other somatotypes, while the time of the ascending part and fast blood flow of rheograms and the diastolic index are significantly greater than in the presentatives of the ecto-mesomorphic somatotype. It has also been found that almost half of the amplitude and derivative indices are significantly higher in girls than in boys of corresponding somatotypes, and most of the time - on the contrary, in boys, than in girls of corresponding somatotypes. Thus, indicators of crus rheogram in practically healthy girls and boys of different somatotypes, inhabitants of the Podillia region of Ukraine have pronounced differences mainly between the representatives of mesomorphic and ectomorphic somatotypes. Established pronounced manifestations of sexual dimorphism of indicators of crus rheogram between adolescents of corresponding somatotypes.
