Comparative Assessment of Morpho-Physiological, Functional Features of Volleyball Players, Taking into Account Their Playing Role

Abstract

Morphological differences in the physique of volleyball players depending on the playing role have been established. Taking into account that longitudinal dimensions for players have a decisive role requiring prediction at the stage of early sports selection, we set the task to identify specific genetic markers predicting the limits of growth processes. In order to predict the growth rate of longitudinal body sizes in volleyball and basketball players we used anthropometry methods and methods of genetic HLA typing, which allowed us to identify specific genetic markers associated with this or that body length. The participation of cardiorespiratory system as an informative indicator of athletes' physical performance, aerobic capacity, and also as a system reflecting the level of adaptability of athletes' organism was established. The use of functional approach allowed to identify promising volleyball players. The morpho-kinesiological analysis of the phases of jumping action with the evaluation of the performed work was carried out. The phase of jumping down, which is regarded as a type of yielding work, is analyzed, then comes the amortization phase, in which there is a forced stretching of muscles, then comes a sharp contraction of muscles and comes the phase of pushing off and the subsequent jumping forward. There is a clear characterization of the main muscles providing push-off, which at this point perform overcoming work.
