Performing vigorous physical activity means a multiorgan system engagement, but the cardiovascular system plays a critical role. In order to provide enough oxygen to activate muscles during repeated physical activity of high intensity, the heart undergoes profound morphologic, functional and electrophysiological alterations, which have been identified as the "athlete's heart syndrome". "The athlete's heart" is a complex, but not precisely defined concept, anatomically and functionally and in relation to health and disease. It means the whole heart enlargement and/or hypertrophy of the cardiac muscle, also increasing economy of cardiac performance at rest and during physical activity with higher maximal functional capacities, all that having an adaptive response to vigorous physical activity. For morphological changes called the "athlete's heart, full-time, programed and intensive physical activity at maximal levels is primarily responsible. But as there are different kinds of physical activities, the degree of those morphological changes is highly variable. Considering many sudden cardiac deaths in sports, it is needless to say how important it is to know where the borderline is between normal changes of the heart due to physical activity and pathological changes due to some cardiac diseases. As sport has a growing socio-economic significance, sudden cardiac death events have to be reduced.
进行剧烈体育活动意味着多器官系统参与其中，但心血管系统起着关键作用。为了在高强度重复体育活动期间提供足够的氧气以激活肌肉，心脏会经历深刻的形态、功能和电生理改变，这些改变已被确定为“运动员心脏综合征”。“运动员心脏”是一个复杂但定义并不精确的概念，在解剖学、功能以及与健康和疾病的关系方面皆是如此。它意味着整个心脏扩大和/或心肌肥厚，同时在休息和体育活动期间心脏功能的经济性也有所提高，最大功能能力增强，所有这些都是对剧烈体育活动的适应性反应。对于被称为“运动员心脏”的形态变化，主要是由最高水平的全日制、有计划且高强度的体育活动导致的。但由于体育活动种类不同，这些形态变化的程度差异很大。鉴于体育赛事中发生了许多心源性猝死事件，不言而喻，了解因体育活动导致的心脏正常变化与某些心脏疾病导致的病理变化之间的界限有多重要。随着体育具有越来越重要的社会经济意义，心源性猝死事件必须减少。
