摘      要：运用多普勒超声心动图，对体表面积无差别的体育专业与普通大学生Tei指数、收缩期左室流出道射流最高速度、心率进行对比研究。结果显示运动员的Tei指数较小、收缩期左室流出道射流最高速度较快、心率较慢，有显著差异。结论：体育专业大学生心脏的收缩、舒张整体功能比普通大学生明显增强，具备着更高的搏出量储备和心率储备。

Abstract: By using Doppler ultrasonic cardiogram, the authors made a comparative study of the Tei index, maxi-mum speed of the jet stream in the outflow tract of the left ventricle during contraction and heart rate of athletes and ordinary colleges students with an identical body surface area, and revealed the following findings: the Tei index of athletes is relatively small; the maximum speed of the jet stream in outflow tract of their left ventricle during con-traction is relatively fast; their heart rate is relatively slow; all of which show a significant difference. The authors concluded that as compared with ordinary college students, the overall function of contraction and relaxation of the heart of athletes were significantly enhanced, and they had a higher level of cardiac stroke reverse and heart rate re-serve.
