“…However, Y. Zhang et al [7] note that the response of central haemodynamics to physical activity is transient, and therefore it is difficult to investigate it to obtain objective results. The importance of peripheral circulation indicators for sports performance was proved in the study by O. Usova et al [9], noting that a decrease in the functional capabilities of the body will be accompanied by a decrease in blood filling of blood vessels, which is expressed in a change in the value of time and amplitude indicators of the rheogram. This is because the condition of the vessel walls, blood flow, and microhaemodynamics of skeletal muscles, especially in the lower extremities, can hinder the successful sports career of any athlete.…”

Statistical modelling of peripheral haemodynamics indicators, which is conducted based on determining anthropometric and somatotypic features of the organism, can be considered a new way of personalising instrumental diagnostic examination. Therefore, determining the suitable rheovasographic parameters of the shin in highly skilled volleyball players of a particular somatotype is relevant. The purpose of this study was to investigate the total influence of indicators of the external structure of the body on the value of indicators reflecting the specific features of blood circulation in the shin in volleyball players of mesomorphic somatotype. A comprehensive clinical and laboratory study of the state of health and physical development of 108 volleyball players aged 16-20 years was conducted. The method of tetrapolar rheography with the use of a diagnostic computer multifunctional apparatus was used to determine the rheovasographic parameters of the shin, amplitude, time, and indicators of the ratio of amplitude and time rheovasographic parameters were evaluated. An anthropometric study of total and partial body measurements was carried out. Somatotyping was performed using the Heath-Carter method. The study selected 28 volleyball players of mesomorphic somatotype. Statistical models were created using direct stepwise multivariate regression analysis. For all amplitude and time rheovasographic parameters of the hip in volleyball players of mesomorphic somatotype, statistical models with high accuracy of description of signs were built. The 10 models included 94 anthropometric dimensions. The key determinants of shin blood circulation parameters are body circumference (most often forearm, neck, and shin circumference), chest and pelvic diameters, thickness of skin and fat folds (most often on the shin, abdomen, flank), and width of the epiphyses of long tubular bones. It was found that the indicators of external body structure within 63.84- 99.99% determine the value of indicators of regional blood circulation on the shin in volleyball players of mesomorphic somatotype. Statistical modelling makes it possible to determine the proper values of individual rheovasographic indicators on the shin depending on the anthropometric parameters of individuals of a certain gender, age, somatotype, which is especially significant for athletes of a certain sport, since their cardiovascular system indicators are greatly influenced by the specifics of sports activity

“…The functional state of an athlete's cardiovascular system is an undeniable factor in sports performance [5,12,19,22]. Many scientific studies have proven the importance of indicators of central [13,18,23,30] and peripheral hemodynamics [26] in increasing the level of fitness of athletes and forming their high potential for adaptation to intensive physical exertion of various directions. In particular, Usova O. V. with co-authors [26] notes that as a result of a decrease in the functional capabilities of the body, a decrease in the speed of blood vessel filling will be observed.…”

Somatotypological features of the body can be considered as a lever of sports achievements, because they have an effect on the efficiency of the energy supply system, physical capacity, ability to adapt, and the state of the cardiovascular system. The purpose of our work is to reveal the correlations between the amplitude parameters of the crus rheovasogram and anthropometric indices in young volleyball players women of different somatotypes. A comprehensive clinical and laboratory study of the state of health and physical development of 108 volleyball players women aged 16-20 years (youth period of ontogenesis) of high sports ranks (from II adult to masters of sports) was conducted. Rheovasographic parameters of the crus in volleyball players women were determined by the method of tetrapolar rheocardiography on a certified computer diagnostic multifunctional complex. Anthropometric determination of the total dimensions of the body and chest, pelvis, limbs, and head was performed according to the recommendations of Shaparenko P. P. (2000), somatotypological – according to the Heath-Carter calculation method (1990). After somatotyping, it was established that 28 women volleyball players belonged to the mesomorphic type of constitution, 27 women athletes were assigned to the ectomorphic and ecto-mesomorphic somatotypes each, and 26 women volleyball players belonged to the medium intermediate type. The analysis of the obtained results was carried out in the license program "Statistica 5.5" using correlation analysis according to Spearman. We found that highly professional women volleyball players, who have different body types, differ in the strength and number of significant correlations between the amplitude rheovasographic parameters of the crus and anthropometric dimensions. The most numerous (18.64 % of the possible correlations, of which 6.82 % are reliable) and the strongest (3 strong with a correlation coefficient from -0.64 to -0.73) correlations between the amplitude indicators of the crus rheovasogram and parameters of the external body structure were recorded in volleyball players women of the middle intermediate somatotype. Ectomorphs had the lowest number and strength of relationships (3.18 % of possible correlations, only 1 reliable). Individual longitudinal dimensions of the body, chest girths and its diameters, transverse dimensions of the pelvis, and skinfold thickness were most often correlated with the amplitude indicators of the crus rheovasogram in women volleyball players of various constitutional types. Determining the features of the correlations is the basis for assessing the harmony of the physical development of women volleyball players and conducting further statistical modeling to determine their appropriate crus rheovasographic indicators.

Aim of the work was to determine the peculiarities of rheographic parameters of the tibia in volleyball players of the general group and individual somatotypes. Materials and Methods: A comprehensive examination of 108 highly skilled volleyball players and 130 practically healthy girls aged between 16 and 20 years who did not play sports was conducted. The rheovasographic parameters of the tibia were determined using tetrapolar reocardiography on a computer diagnostic complex with the assessment of amplitude, time, and indicators of the ratio of amplitude and time rheovasographic parameters. A somatotypological study was conducted based on a calculated modification of the Heath-Carter method (1990) with the division of volleyball players and non-athletes into 4 constitutional groups: mesomorphic, ectomorphic, ecto-mesomorphic, and intermediate type. Results: Significant differences in the value of individual amplitude and most tibia rheovasographic parameters between volleyball players and girls of the control group were revealed. In athletes, the amplitudes of the systolic, diastolic and rapid blood filling, the duration of the rheographic wave, the time of the ascending and descending parts of the rheogram and slow blood filling were statistically significantly higher. Somatotypological features of peripheral hemodynamic indicators were determined in volleyball players; the greatest differences in the indicators of regional blood circulation on the tibia were recorded for representatives of the ectomorphic somatotype; between volleyball players and non-athletes with ecto-mesomorphic somatotype, there was no significant difference in the value of all tibia rheovasographic parameters. Conclusion: Systematic training and competitions lead to prominent changes in rheovasographic indicators of the tibia in young female volleyball players, which are manifested by a better state of capillary and venous blood filling of the tibia muscles, but at the same time a reduced speed of regional blood flow due to a reduced tone of the vascular wall of small and medium arteries.
