Physical exercise is considered as stress for animal organism because it generates different types of responses, as negative effects caused by free radicals. In this study, the hematologic response level of red blood cells and the presence of oxidative alterations in the membranes of horses subjected to a test of high-intensity exercise were evaluated. The results indicated a significant increase in the number of red blood cells, hematocrit and hemoglobin concentration, reaching maximum values when the horses reach fatigue during exercise test, and then decreased during aerobic recovery. The three parameters behaved similarly. Damage to the membrane of red blood cells was estimated by the degree of peroxidation, measured by chemiluminescence, over the exercise period. The values produced by peroxidative damage are high at the time of exercise exhaustion, and remained stable after recovery. The correlation between the studied hematological values and the degree of damage of the erythrocyte membrane showed that, despite the increased circulating red blood cells due to splenic contraction, the erythrocytes are damaged as a result of the predominant oxidizing environment during the maximal exercise

Key words: Horse, red blood cells, exercise, chemiluminescence, hematocrit.
