采用无创性方法对14名职业公路自行车赛选手和11名年龄匹配的久坐不动的受试者进行了静息状态下心脏大小和左心功能的研究。心电图结果与耐力运动员以前的研究结果一致，心电向量图数据显示电动力前移。超声心动图显示，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在舒张末时的数值较高。自行车运动员的左心室体积和左心室质量的导出值也要大得多，放射学测量的总心脏体积与超声心动图测量的总心脏体积之间有很好的一致性。最大耗氧量与左心室舒张末内径显著相关。
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.
