The objective was to evaluate the influence of different frequencies of training on serum concentrations of lactate, CK, AST and LDH and on clinical and hematological parameters of horses after exercise of high intensity and short duration. Venous blood samples were obtained from 16 Quarter Horses, divided into two groups: regular training group (GTR) and sporadic training group (GTE) in seven different times: 30 minutes before exercise (M0), immediately after (M1), 30 minutes (M2), one (M3), two (M4), six (M5) and 24 (M6) hours after exercise. Differences between groups were observed in VG, hemoglobin concentration, VCM and number of lymphocytes, including on resting. Between the moments, in GTE significant differences were observed after exercise for lactate, VG, PPT, granulocyte number and LDH and in GTR for VG, total count of red blood cells, hemoglobin concentration and LDH. We conclude that the assessed horses showed changes in serum concentrations of lactate and muscle enzymes and in clinical and hematological parameters after exercise. The lower magnitude of elevation after exercise, observed in GTR, for HR, RR and VG suggests that these animals were better adapted to exercise. The low magnitude of elevations of CK, AST and LDH concentrations and the rapid return to baseline, including lactate, HR, RR and hematological parameters suggest that evaluated animals were conditioned and able to perform the established type of exercise, with no difference between regular training and the sporadic training.
