Relationships of temporal rheovasographic parameters of the lower leg with anthropometric dimensions in female volleyball players

Annotation. Constitutional features of the human body can be considered as a guarantor of sports achievements, in volleyball in particular because constitutionality is inherent in adaptive capabilities, physical performance, and indicators of the cardiovascular system. The purpose of the work is to investigate the correlations between temporal parameters of the rheovasogram of the lower leg and anthropometric dimensions of the body in volleyball players of different somatotypes of youth. A study was conducted on 108 female volleyball players aged 16-20 years of high sports categories with a sports experience of 6.361±2.865 years. Temporal rheographic parameters of the lower leg were determined by the method of tetrapolar rheocardiography on a certified computer diagnostic multifunctional complex. Anthropometric research was carried out according to the recommendations of P. P. Shaparenko (2000). In the somatotypological study, the Heath-Carter method (1990) was used. It was determined that there were 28 volleyball players were a mesomorphic type, 27 were an ectomorphic type, 27 were an ecto-mesomorphic type, and 26 were an average intermediate type. Statistical analysis was performed in the “Statistica 5.5” program; the Spearman method was used to establish correlations between hemodynamic and anthropometric indicators. It was found that volleyball players with different somatotypes differ in the number and strength of relationships between anthropometric dimensions and temporal rheovasographic parameters of the lower leg. The most numerous relationships were in volleyball players of the ecto-mesomorphic (strong 0.91% of possible correlations, medium – 29.55%, of which reliable – 16.82%) and ectomorphic (strong 2.27%, medium – 25.91%, of which reliable – 14.55%) somatotypes; the smallest number of relationships was found in volleyball players of the mesomorphic type (strong 0.91%, medium – 21.18%, of which reliable – 8.64%). In volleyball players of mesomorphs, the transverse and girth dimensions of the lower leg and thigh, skin-fat folds on the lower leg and thigh were most often correlated (direct relationships) with temporal rheographic parameters of the lower leg; in ectomorphs – body weight, external conjugate, height of pubic and acromial points, circumferences of the shoulder, hand, thigh and lower leg (direct relationships); in ecto-mesomorphs – craniometric dimensions, circumferences of the lower leg, thighs, chest, diameters of the pelvis (direct relationships), skin-fat folds on the abdomen, sides and thighs (only inverse); in female athletes of the average intermediate somatotype – total and longitudinal body dimensions, circumferences of the chest, width of the distal epiphyses of the shoulder and thigh (direct relationships). Determining the features of the relationships between somatometric and rheovasographic indicators is the basis for conducting mathematical modeling of the appropriate indicators of peripheral hemodynamics in female volleyball players.
