The study was conducted on 24 sport horses in best shape as result of the previous intensive training sessions. The variability of the haematological parameters was monitored in relation to the individual physiological particularities of age and sex before and after the routine training sessions. The adult horses displayed after the training exercise a 32.4% increase of the erythrocytes number, a 29.4% increase of the neutrophils number and a 23% increase of the hematocrit; the lymphocytes number decreased by 14.3%. The erythrocytes number increased after the training exercise by 18.5% in males horses and by 16.6% in female horses, the hematocrit increased by 20% in the male horses and by 16% in the female horses, while the N/L ratio increased by 56% in the males and by 26% in the females.

 Key words: sport horse, adaptative capacity, haematological indices
