采用超声心动仪对 68名入选 2 0 0 0年奥运会的优秀男运动员进行测试 ,随机选取 2 5名健康学生作为对照 ,以观察与探讨当代优秀运动员左心结构与功能的改变及运动对心脏功能的影响。结果表明 :不同运动项目的运动员随着运动年限的延长 ,左室内径、左室重量及重量指数均有所增加。而室壁厚度仅有轻度的改变。运动员的主要心功能指标明显高于青年学生 Sixty elite male athletes selected for the 2000 Olympic Games were tested by echocardiography. Twenty-five healthy students were randomly selected as controls to observe and explore the changes of left ventricular structure and function of contemporary elite athletes and the effects of exercise on heart function Impact. The results showed that left ventricular internal diameter, left ventricular mass and weight index increased with the increase of exercise duration for athletes of different sports. The wall thickness only slight changes. The main cardiac function index of athletes is obviously higher than that of young students
