Abstract

This study is to evaluate cardiac systolic and diastolic function of Chinese male canoeists during heavy load exercise training by Doppler echocardiography. Eighteen young male volunteer canoeists were tested, and trained five weeks. Then the change of cardiac systolic and diastolic function of the tester was examined by the Doppler echocardiography method.The results showed that there were no significant differences of LVEF and Δ%D, but the E/A ratio of elite canoeists reduced (p<0.05) after the heavy load exercise training. Moreover, the ratio of E/A less than 1 was found in two elite canoeists. The further research is required to understand the mechanism of the change. These results showed that monitoring of diastolic function was more meaningful than monitoring of systolic function during the heavy load exercise training, especially not neglected the cardiac function of elite canoeists.
