[The local immunity reactions of swimmers on the Russian all-star team]

Dynamic observation of the national team of swimmers for a period of 3 years demonstrated that physical and psychosomal loadings of competitive sport led to the suppression of local immunity, depending on the level of competitive stress. In a certain number of sportsmen the phenomenon of the complete disappearance of some classes of immunoglobulins and normal antibodies from saliva was registered. The daily rhythms of immune reactions had no influence of the regularities of fluctuations in the levels of immunoglobulins and antibodies at different periods of sporting activities when these changes were most pronounced. Still the peaks of immunoglobulin levels were registered in the morning and those of normal antibodies, in the evening after physical strain. During the period of competitions at the time of a sharp drop in the content of immunoglobulins in saliva a rise in the level of anamnestic antibodies was observed. The dynamics of immune reactions in saliva did not essentially depend on the sex of swimmers. The results of these studies are indicative of the necessity of immunoprophylactic and immunocorrective measures in the group of immunological risk.
