FEATURES OF THE IMMUNE STATUS OF ATHLETES OF ACYCLIC SPORTS (FIGHTERS AND BOXERS) DEPENDING ON THEIR SPORTS QUALIFICATION

The study of blood cell counts and analysis of their changes in wrestlers and boxers made it possible to reveal special features of the population and subpopulation spectrum of lymphocytes in wrestlers and boxers of different qualifications. The sportsmen of power sports with anaerobic metabolism (wrestlers and boxers a significant decrease in the general population of T-lymphocytes) occured due to a decrease in circulation of main subpopulations of T cells: T-helper and T-cytotoxic. There were also a decrease in number of cells with adhesion receptors (CD11b), the number of B-lymphocytes and cells bearing apop-tosis readiness markers (CD95), opposite to elevated cell count with lymphocytes early positive activation(CD25) markers. An increase in cell number with receptors for interleukin-2 (CD25) with parallel decrease in the number of hematopoietic cell precursors and the main subpopulations of lymphocytes (T, B lymphocytes) is considered to be a reflection of the negative impact of intense speed-strength anaerobic regimen on immune system, and possible may be resulted in immunodeficiency in these athletes. The immune status of athletes going in for acyclic sports is characterized by marked cytopenia of relative and absolute numbers of T-lymphocytes, both T-helper and T-cytotoxic lymphocytes, and also CD16 and CD56 positive cells, belonging to congenital immunity factors, and also B lymphocytes (CD20), compared to sportmen groups of skiers and swimmers, and that reflects a decrease in intensity of immunopoiesis in anaerobic type of energy metabolism, and considered to be a significant factor, affecting immune system quality reaction and T- and B-cell cooperation reaction.
