Abstract :

Exercise physiology is the most useful information that make the race horse such a super athlete and good managed. This study was carried out on twenty one thoroughbred race horses in order to evaluate physical fitness and performance through physical ( Heart rate, Respiratory rate, Body temperature and capillary refilling time ) , hematological ( RBCs, PCV, Hb, total and Differential leucocytic count) and hematochemical evaluation ( TP, Albumin, AST, ALT,CK,LDH, Lactic acid, Glucose, Cholestrol,Na, K, Cl and Urea , Creatinine, Ca, P and Mg ). Physical examination and Blood samples were collected before and at 5, 15 and60 min. after 1600 meter exercised. The results showed significant increase in all physiological , hematological and hematochemical parameters 5 min after exercise that returned to basal levels after 60 min. rest. The results can be useful index about horse performance, the effect of exercise on horse metabolism and helpful in management protocols of athletic horses. Key Words : physiology, hematology, biochemical , exercise, Thoroughbred horses
