ABSTRACT: The acute phase reaction occurs in response to diseases, surgical trauma and can happen after strenuous exercise, like long distance events. This study aimed to evaluate the Serum Amyloid A (SAA), pro-inflammatory interleukins (IL-1β and TNFα) and creatine phosphokinase (CK) after free speed races like physical stress markers in endurance horses. Blood of 21 trained horses that competed in tests of 80, 120 and 160km, was taken before and after race. There was a significant increase in CK and SAA after the race in all horses, as well as the anti-inflammatory interleukin IL-10. But when results were compared between the groups, only the SAA was different, being higher in 160km horses. There was no change in pro-inflammatory interleukins IL-1β and TNFα before and after the event; however, the TNFα was higher in 160km horses after the race. Based on data obtained in this study it was concluded that stress is more dependent on the distance than speed imposed and that SAA is a good marker of physical effort, since it is accompanied by other markers well established as CK. Interleukins are not a good markers since they did not change significantly.
