Сorrelations of rheographic indicators of arterial tone in the shin with anthropometric dimensions in volleyball players of different somatotypes.

Abstract

Constitutional features of the body of volleyball players can have a significant impact on sports performance and are closely related to indicators of the cardiovascular system. The aim of the work is to investigate the relationships between the tonic parameters of the lower leg rheovasogram and external body dimensions in highly professional female volleyball players of different somatotypes. A study was conducted on 108 female volleyball players aged 16-20 years playing at a competitive level with sports experience of 6.361 ± 2.865 years. Indicators of the tone of the shin arteries were determined as derivatives of amplitude and time rheovasographic parameters using the tetrapo lar rheocardiography method. Anthropometric research was carried out according to the recommendations of P. P. Shaparenko (2000). The Heath-Carter method (1990) was used in the somatotypological study. Statistical analysis was performed in the “Statistica 5.5” program; Spearman’s method was used to establish correlations between hemodynamic and anthropometric indicators. The results of our study also indicate pronounced differences in the strength and quantity of relationships between rheovasographic parameters of the shin, which reflect vascular tone, and anthropometric indicators in volleyball players with different somatotypes. More relationships were detected in volleyball players of the ectomorphic somatotype; the smallest number of relationships was found in volleyball players of the mesomorphic type. In volleyball players of all somatotypes, body composition indicators were the tone indicator of all arteries of the shin were most closely correlated.
