SIMULATION OF APPROPRIATE RHEOVASOGRAPHIC INDICATORS OF THE FEMUR IN VOLLEYBALL PLAYERS OF ECTOMORPHIC SOMATOTYPE DEPENDING ON ANTHROPOMETRIC FEATURES.

Objective: The aim of the study was to build regression models of rheovasographic parameters of the femur in volleyball players of ectomorphic somatotype depending on the features of anthropometric indicators.

Patients And Methods: Materials and methods: 113 volleyball players of a high level of sportsmanship of adolescence (from 16 to 20 years old) underwent somatotypological study according to the calculated modification of the Heath-Carter method. 26 volleyball players of ectomorphic somatotype were selected. They performed tetrapolar rheocardiography on a computer diagnostic complex according to the method of Ronkin and Ivanov to establish the indicators of peripheral hemodynamics and anthropometry according to the method of V.V. Bunak. The mathematical models were built in the package "STATISTICA 5.5" for Windows using direct stepwise regression analysis.

Results: Results: Due to the use of multifactor regression analysis, we performed mathematical modeling of rheovasographic parameters of the femur in volleyball players of ectomorphic somatotype, which allows to determine the appropriate values of these indicators taking into account anthropometric and somatotypological features of each athlete. Linear regression equations for 16 indicators of peripheral hemodynamics were constructed from possible rheovasographic parameters of the femur. 4 models were built for time indicators (in which the indicators of the external structure of the body by 59.31 - 78.01% determine the value of the parameters of this group); for amplitude - 5 (coefficient of determination of features from 54.00 to 76.13%); for integral indicators of the rheovasogram of the femur - 7 (coefficient of determination 60.10 - 77.41%).

Conclusion: Conclusions: In volleyball players of ectomorphic somatotype up to 16 constructed regression models to determine the appropriate rheovasographic parameters of the femur included 94 dimensions of the external body structure, among them were often the thickness of fat folds, craniometric parameters, girth and anterior-posterior body dimensions, somatotype components.
