BACKGROUND: Professional athletes-skiers, swimmers, wrestlers, boxers of the highest sports qualifications participated in the study during the wintertime (December, January, February) free of training and competitive loads.
METHODS: We conducted a quantitative analysis of A, G, M immunoglobulins, complement hemolytic activity and its fragments C1-C5 in blood serum.
RESULTS: In the group of athletes belonging to acyclic types of sports (wrestlers and boxers) we revealed a double increase in IgA level with a parallel decrease in immunoglobulins of secondary immune response (IgG). In representatives of cyclic sports (swimming, skiing) the parameters of antibodies did not differ from corresponding age norms. We revealed a linear increase in the IgA and IgM products as the qualification and athlete’s adaptation to physical loads increase. However, the highest level of IgG was revealed in the group of high-grade athletes. The increase in CIC content was also registered in masters of sports from cyclic types of sports (swimmers and skiers), and it can be the consequence of the increase in circulating blood volume as a result of the output of blood corpuscles from depos, hemapoiesis stimulation, and transitory delay of CIC elimination under compensatory load on excretory systems of the body.
CONCLUSIONS: We established that the qualification of athletes influences significantly the parameters of humoral immunity forming so-called profile of changes. At the same time, these changes can be regarded as the characteristic of athlete’s belonging to a certain specialization and sport qualification as well as belonging to cyclic, predominantly aerobic, types of sports such as swimming, skiing, or to acyclic anaerobic types of sports like boxing or wrestling. The changes revealed can be mediated through desynchronosis in the dynamics of the adaptive processes of different intensity at the level of humoral immunity system in the process of the improvement of sport performance.
