Serum macro minerals in adults Thoroughbred horses, before and after the high intensity exercise.

Abstract

With the aim of analyzing the effect of high intensity physical activity on the serum values of macro minerals, 19 clinically health adults Thoroughbred horses, males and females from 3 to 5 years of age, were submitted to a galloping in a 2,000 meters sand track. Two blood samples were collected from each animal, one before and another after the high intensity exercise. The results had shown some significative changes (p<0.05) with an increase in the serum values of calcium and magnesium and a decrease in serum and potassium. Meanwhile, there were no alterations (p>0.05) in the concentration of phosphorus and potassium. It is concluded, therefore, that the high intensity exercise leads to transitory and physiologic changes in the serum concentration of macro minerals.
