The present research is the result of a Vaquejada Simulation Test (VST), developed to evaluate the possible changes ocurring in horses physiological and metabolic adaptations. Were used thirteen horses, however nine were “puxar” horses and three were “esteira” horse.These two groups did different types of exercise. It was evaluated: heart rate, respiratory rate, hematocrit, total plasma protein, glucose, lactate, urea, creatine, triglicerides, total cholesterol and HDL, creatine kinase and aspartate aminotransferase, glutamate, glutamine and alanine.Samples were collected at: pré-test (fastining sample), immediately after VST (T0), and at 15(T +15), 30 (T +30) and 240 (T +240) minutes after the VST. However “esteira” horses did collection two times after two rounds, T0 C1 and T0 C2. Presented results were submitted to ANOVA (P<0.05) and Tukey Tes(P<0.05). “Puxar” horses presented significant differences in FC, FR, [PPT], [HT], [GLI], [LAC], [ALA] and [CR]. “Esteira” horses presented significant changes (P<0.05) in FC, FR, [PPT], [HT], [GLI], [LAC], [COLT] and [GLN]parameters. The VST demonstrated that horses performed anaerobic exercise, but “puxar” and “esteira” horses spent energy differently, when they were compared. This defferenciation between both groups of horses indicate that they need specific nutrition and training in order to develop their fitness for best performance.
