Conclusion
Kathiawari horses remaining one of the long surviving endurance horse breed, with its legendary roles in World Wars, their exercise performance assessment becomes important. Exercise physiology and cardiac evaluation is very much important and directly related to performance in horses. The cardiac biomarkers such as cTnI, cTnT, CK-MB and NT-proBNP showed a highly significant increase after exercise when compared to their levels before exercise. In the post exercise echocardiographic findings, significant increase in the left ventricular dimensions and systolic functions were observed. As normal reference values have not been reported in Kathiawari horses, this study established the normal reference ranges for future usages.
