Vigorous physical training induces left ventricular hypertrophy (LVH), a so-called "athlete's heart". The hypertrophic response represents an adaptation to the increased haemodynamic load on the heart associated with physical exercise. Wall thickness and/or left ventricular internal diameters are specifically increased depending on the type of haemodynamic load (volume- or pressure load). It is a consistent finding that left ventricular mass is increased in elite athletes when compared with sedentary controls, but few athletes have cardiac dimensions exceeding accepted normal values. Most commonly these athletes are male oarsmen. Occasionally, it may be difficult to distinguish physiological LVH from primary heart disease and therefore it is of importance also for physicians to be familiar with the "athlete's heart". Also, the sensitivity of the non-invasive methods for detecting coronary heart disease is reduced in athletes with LVH. This should be considered in the planning of the diagnostic strategy in athletes with LVH and suspected ischaemic heart disease.
高强度体育训练会导致左心室肥厚（LVH），即所谓的“运动员心脏”。这种肥厚反应是对与体育锻炼相关的心脏血流动力学负荷增加的一种适应。根据血流动力学负荷的类型（容量负荷或压力负荷），心室壁厚度和/或左心室内径会有特定增加。与久坐不动的对照组相比，精英运动员的左心室质量增加是一个一致的发现，但很少有运动员的心脏尺寸超过公认的正常值。这些运动员最常见的是男性划桨运动员。偶尔，可能难以区分生理性左心室肥厚和原发性心脏病，因此医生熟悉“运动员心脏”也很重要。此外，左心室肥厚的运动员检测冠心病的非侵入性方法的敏感性会降低。在为左心室肥厚且疑似缺血性心脏病的运动员制定诊断策略时应考虑到这一点。
