Cardiac dimensions and left ventricular function were investigated at rest with non-invasive methods in 14 professional road race cyclists and in 11 age-matched sedentary control subjects. The electrocardiographic findings were in agreement with previous studies in endurance athletes and the vectocardiographic data showed anterior displacement of the electrical forces. Echocardiographic dimensions at end-diastole showed higher values in the cyclists for left ventricular internal diameter, left ventricular posterior wall thickness, and interventricular septal thickness. Derived values for left ventricular volume and left ventricular mass were also much larger in the cyclists and there was excellent agreement between total heart volume measured with radiology and total measured by echocardiography. There was a significant correlation between maximal oxygen consumption and end-diastolic left ventricular diameter.
采用非侵入性方法，对14名职业公路自行车运动员和11名年龄匹配的久坐对照者在静息状态下的心脏尺寸和左心室功能进行了研究。心电图结果与先前对耐力运动员的研究一致，心电向量图数据显示电动力向前移位。舒张末期的超声心动图测量结果显示，自行车运动员的左心室内径、左心室后壁厚度和室间隔厚度的值更高。自行车运动员的左心室容积和左心室质量的推导值也大得多，放射学测量的全心容积与超声心动图测量值之间具有良好的一致性。最大耗氧量与舒张末期左心室直径之间存在显著相关性。
