The effect of exercise on some serum biochemical parameters concentration of Arab horse

It seems that the evaluation of parameters like serum biochemical changes following intense physical activity can help to provide data which may help in predicting the athletic capacity of horse in racing conditions. In present study, serum concentration of some biochemical factors was determined before and after intense physical activity in nine, 4-10 years old Arab horses. The blood samples were collected at 1 h before (T0) just after )T1(, 3 hours (T2) and 24 hours (T3) after running with maximum speed in a 1250-meters course. The measuring of serum values of total protein, albumine, BUN, creatinine and glucose and also serum activity of creatine phosphokinase and lactate dehydrogenase enzymes were done by routine laboratory methods. The data were analyzed statistically with one-way repeated measures ANOVA and Tukey's test. The results showed that all of the measured parameters, except BUN were significantly increased after running .It seems that heamoconcentration caused by severe sweating and stress induced by racing conditions, are the reason of these changes.
