Abstract

Resting echocardiographic measurements have been made in 22 endurance athletes (20 cyclists and 2 long distance runners) for 6 years. Every athlete was measured several times, thus altogether 78 examinations were achieved. Results were plotted against the age between 19 and 28 years. Body height did not change at all, body weight and surface area displayed a slight elevation. Left ventricular internal diastolic (LVIDd) and left ventricular posterior wall diastolic thickness (LVPWTd) did not change, interventricular septum diastolic thickness (IVSTd) slightly elevated, so an elevation of the IVSTd/LVPWTd quotient was observed. The shortening fraction and the ejection fraction (EF) increased, heart rate (HR) decreased linearly during the whole examination period. Stroke volume index rose in the first period only, cardiac index was relatively high in the first period but decreased in the second half of the observation period. Elevation of the ISTd/LVPWTd quotient is supposed to be due to an elevated share of isometric load with cycle racers; the continuous decrease of HR is explained by the training-induced alterations of the autonomic equilibrium, while the steady rise of EF can be regarded as a common outcome of the elongation of diastolic filling time, of decreasing compliance of the endurance-trained heart and of an increasing share of the Frank-Starling mechanism in the resting cardiac function.
