Abstract

This study aimed to evaluate the serum activity of creatine kinase (CK), aspartate aminotransferase (AST), lactate dehydrogenase (LDH) and plasma lactate in Standardbred horses after performing physical activity. The serum levels of these enzymes were measured in two moments: M1 immediately after exercise, and M2 24 hours after exercise. There were no differences in CK, AST and LDH concentrations between M1 and M2. For plasma lactate, there were higher values in M1. The level of significance was set at 5%. It concludes that the physical activity performed by Standardbred horses, at submaximal levels, no affects the serum activity of muscle enzymes. Good physical conditioning favors the quick recovery of animals after demanding physical activities.
