摘　　要：为了评价不同项群运动员左心室舒张功能,对12名耐力项目运动员和12名速度力量项目运动员12min前后二尖瓣血流频谱进行了检测。结果表明:12min跑后耐力组血流速度积分和E/A明显减小,速度力量组血流速度积分、E峰值和E/A减小十分明显,A峰值减小明显,两组运动员血流速度积分、E峰值和E/A存在显著差异。说明,耐力组左心室舒张主动松驰及被动充盈能力均好于速度力量组。In order to study the diastolic function of the left cardiac ventricle in athletes of different event groups the blood flow frequency spectrums of the mitral valves were examined in 12 endurance runners and 12 speedendurance runners before and after running for 12 minutes. It was indicated that after 12 minutes of run the blood flow rate integral and the E/A value decreased remarkably in the endurance group. In the speedendurance group the blood flow rate integral, the E peak value and the E/A value decreased remarkably. And the A peak value decreased as well. There existed significant differences in blood flow frequency spectrum, E peak value and E/A value between the two groups of runners. It is shown that the active diastolic relaxation and the passive filling ability of the left cardiac ventricle of the endurance group are better than those of the speedendurance group.
