Effect of exercise on some minerals, metabolites and enzyme activities in the serum of trained Arabian horses

Abstract

The exercise-induced variations of some biochemical parameters including calcium (Ca), phosphorous (P), iron (Fe),copper (Cu), manganese (Mn), selenium (Se), zinc (Zn), sodium (Na), potassium (K), chlorine (Cl), glucose, urea, creatinine, lactatedehydrogenase (LDH), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and creatine kinase (CK) were assessed inthe serum of 25 Arabian horses. Blood samples were taken from the jugular vein 3 different times: before exercise, 5 h after exercise, and18 h after exercise. Statistical analysis was performed using SAS (version 9.2; SAS Institute, Cary, NC, USA). Ca, Cl, glucose, and ureashowed significant (P < 0.05) changes due to exercise. There was significant increase from before exercise to 5 h after exercise in ureaconcentrations while Ca and Cl concentrations significantly decreased. A significant ascending trend for Ca between 5 h and 18 h afterexercise was also seen, while glucose and urea had a significantly descending trend. No significant time-based variations were observedfor other variables. The results of the present study indicated that exercise could affect the value of some biochemical parameters, whichcould be used in future studies evaluating the health status of Arabian horses.
