Correlations of time indicators of thigh rheogram with anthropometric dimensions in volleyball players of different somatotypes

Abstract

The constitutional features of the organism are an essential lever of sports performance, because they affect the general and special physical performance, aerobic productivity and efficiency of energy supply systems, in particular the indicators of central and peripheral hemodynamics. The aim of the study was to establish the features of the relationships between the temporal parameters of the rheovasogram of the thigh and anthropometric indices in highly qualified young women volleyball players, who belong to different constitutional types. An anthropo-somatotypological study of 113 high-level volleyball players of youth age (from 16 to 20 years old) was conducted. Anthropometric research was carried out by the method of V.V. Bunak (1941), somatotypological – by the calculated modification of the method of Heath-Carter (1990). According to the results of somatotyping, it was found that 29 volleyball players belonged to the mesomorphic type of constitution, to the ectomorphic type – 26 volleyball players, to the ecto-mesomorphic type – 27 volleyball players, to the middle intermediate type – 26 volleyball players, to endo-mesomorphic type – only 5 people. Rheovasographic parameters of the thigh were determined using tetrapolar rheocardiography on a computer diagnostic complex. Estimation of temporal rheovasographic parameters was performed according to the method of Ronkin and Ivanov [1997]. The analysis of the obtained results was performed in the licensed program “Statistica 5.5” using Spearman’s correlation analysis. We found that in volleyball players of mesomorphs with indicators of external body structure, the temporal parameters of the thigh rheovasogram had few reliable mostly medium strength, direct correlations, except for the time of the ascending part of the rheogram and slow blood supply. In volleyball players of ectomorphic somatotype, the established relationships indicate that with increasing diameters of the pelvis and girth of the forearm, crus, thighs, there will be an elongation of the time parameters of the rheovasogram of the thigh. Volleyball players with an ecto-mesomorphic somatotype of the body showed a fairly large number of reliable inverse correlations, the thickness of the skin and fat folds is inversely proportional to the most time parameters of the thigh rheovasogram, except for the time of slow blood supply. Volleyball players of the intermediate somatotype, compared with other observation groups, found the most numerous relationships between anthropometric size and time indicators of the rheovasogram.
