Abstract

Strenuous exercise promotes changes in salivary IgA and can be associated with a high incidence of upper respiratory tract Infections. However, moderate exercise enhances immune function. The effect of exercise on salivary IgA has been well studied, but its effect on other immunological parameters is poorly studied. Thus, this study determined the effect of moderate acute exercise on immunological salivary parameters, such as the levels of cytokines (TGF- and IL-5), IgA, -amylase and total protein, over 24h. Ten male adult subjects exercised for 60min at an intensity of 70% VO2 peak. Saliva samples were collected before (basal') and 0, 12 and 24h after an exercise session. The total salivary protein was lower after 12 and 24h than immediately after exercise, whereas -amylase increased at 12 and 24h after exercise compared with basal levels. The IgA concentration was increased at 24h after exercise relative to immediately after exercise, and there was no difference in the IL-5 while TGF- concentration increased in recovery. In conclusion, 70% VO2 peak exercise does not induce changes immediately after exercise, but after 24h, it produces an increase in salivary TGF- without changing IL-5. (AU)
