“…The dimensional changes in the heart, for instance the increase in heart volume and muscle mass are the most obvious symptoms of the athlete's heart and they have given rise to most misinterpretations (6,28). The heart volume in various types of sport is very different (Fig.…”

The term the "Athlete's Heart" was first used over 80 years ago, when by the use of percussion examination an increase in the heart size of cross country skiers was observed (9). Following these investigations the increase in the heart of endurance trained athletes could also be confirmed using radiographic methods (5, 25). An increase in the heart size is also a result of various pathologic processes, for instance a myocarditis, a pressure-or volume-overloading of the heart, a myocardial infarction etc., thus for many decades the enlarged heart of trained athletes was often regarded as being pathologic.Many investigations in particular the book by Reindell et a!. 1960 (28)using pathologico-anatomical, radiographic, electrocardiographic, haemodynaniic and spiroergometric investigations -showed that the heart, enlarged as a result of endurance training was not damaged but was an indication of a particularly efficient heart. Despite these investigations other researchers remained sceptical and repeatedly described the athlete's-heart-syndrome as pathologic: physiological variabilities were not recognized or often haemodynamic values were misinterpreted. Even in the American standard work by Friedberg "Diseases of the Heart" one could still read 7 years ago, that the athlete's heart was a syphilitically or rheumatically damaged heart (6). Recent investigations in particular those using echocardiography have produced a series of new results, which have increased our understanding about the trained heart and in particular about the different effects of various training types (1-4, 7, 8, 10-17, 27-35, 37-39).

“…Catheterization studies have shown no difference in the filling pressures of the left ventricle between trained and un trained hearts at rest fl, 22], On the other hand, an increase in the heart volume is universally accepted and detectable already after a two months' training period, correlating with the in crement of the stroke volume [7]. The catheterization data [1,22] and the finding that training of subjects with inherited brady cardia results in increased stroke volumes without prolongation of the diastolic inflow phase [8] suggest an enhanced filling of the trained heart without a necessary change in the filling pres sures and times. This is possible only by increased distensibility of the trained heart [11], The same property, via increased dia stolic stretch [21], is probably the mechanism which operates in maintaining a constant ICT and DP/ICT in spite of a larger heart.…”

“…When training ceases, an athlete's heart size reduces again (e22, e23), with individually variable rates of regression. Immobilization (e.g., bed rest) leads to rapid regression of heart size (2). Athlete's heart often regresses incompletely, however, with persistent left ventricular enlargement despite normalization of chamber thickness (e13, e23).…”
