A total 204 were sampled 13 assessed. K-means clusters analysis classify in two groups. Significant differences found for nine studied. Two formed; cluster 1 grouped most is characterized by a higher leukocytes (mainly lymphocytes), carbonyl On other hand, 2 groups with lower cortisol concentrations, but antioxidant capacity. Further studies required selecting (rodeo or draft work) how these physiological should considered when assessing their state.
