It was studied the intense exercise effects on plasmatic glucose, plasmatic insulin and blood lactate from Purebred Arabian horses. Twenty four trained horses were submitted to incremental exercise test on treadmill. Therefore, after warm up (4 min./4.0 m.s-1) the treadmill was sloped (10%) and the speed gradually increased at intervals of 2 minutes to 6, 8 e 10 m.s-1. After maximum effort, it was performed the deceleration to 3.0 m.s-1, for 20 minutes, which corresponds to the period of active warm down. Blood samples were taken from the animals at these different times, glucose, insulin and lactate were analyzed. Results show that significant difference (P? 0.05) was obtained from the rest. The glucose was found to be statistically constant at all steps of the exercise, reaching high levels (p? 0.05) at period of warm down and the a insulin was decreased with the exercise. Blood lactate also increase levels (p? 0.05) in relation to incremental of effort intensity. It is possible to conclude that sympathic neural activity plays major role in alterations of the physiological variables analyzed during intense exercise.KEY WORDS: Equine, exercise, glucose, insulin, lactate.
