title: [Form, size and function of the sports heart--differentiation from pathological findings].
abstract: Dependent on the nature, intensity and scope of muscular exercise, regular athletic training can result in changes in the size and form of the heart, which can be recorded by radiologic and echocardiographic techniques. Brief anaerobic exercise and purely static forms of training (sprint, strength sports) do not produce substantial increases in the size of the heart, but a rotund heart shape with rounding of the cardiac tip and in some cases a discrete increase in the wall thickness of the ventricular myocardium is frequently observed. Dependent on the scope of the training and the intensity, aerobic, endurance-oriented training (endurance sports) can induce considerable enlargement of all cardiac chambers with a change in the cardiac configuration, which is most nearly comparable to combination mitral vitium. Comparison of physiological hypertrophy of the athletic heart with pathological forms of cardiac hypertrophy (such as cardiomyopathies) is in many cases not unequivocally possible with plain X-ray films, but it is usually successful with echocardiographic examination methods.
