Recent studies reported reduced immunity in athletes following exercise. Physical activity affects both cellular and humoral immune functions. Scant information exists on exercise-induced changes the system among children. The purpose of present study was to investigate effect aerobic exercise several aspects functions 10-12 year-old highly trained female gymnasts (n = 7) untrained girls 6). All were pre-pubertal. Venous blood samples drawn before, immediately after 24 h 20 min treadmill running (heart rate 170-180 beats.min-1). White cells' number rose significantly remained elevated for h. increase leukocyte due an granulocytes as well lymphocytes monocytes. While neutrophil count returned basal values h, monocytes Exercise resulted a significant elevation T cell lymphocytes, helpers, suppressors natural killer cells. normal There no B had serum IgA, IgM, IgE, IgG sub-types (IgG1, IgG2, IgG3 IgG4). No differences observed between girls. In summary, generally similar those described adults. Whether transitory effects are related increased susceptibility illness is still questionable.
