Abstract:
To study the effect of exercise on cardiac calcitonin gene-related peptide (CGRP) using immunnohistochemistry and the technique of computer image analysis, the expression and mechanism of cardiac CGRP on the animal model trained with different exercise intensities were investigated. The result showed that long-term low intensity of exercise was not able to induce obvious change in cardiac CGRP. After long-term moderate intensity of exercise, the expression of cardiac CGRP increased so as to improve blood supply and protect myocardium. Long-term high intensity of exercise decreased expression of cardiac CGRP and weakened the protection of myocardium which could be a chief cause of myocardial ischemia.
