The aim of this study is to collect longitudinal data on the cardiac structure and function and possible cardiac pathophysiology of endurance athletes who have quit competition. in relation to the phenomenon "sudden death" we will examine to what extent the heart shows the marks of this extreme exercise load. A second group that will be studied are the endurance athletes who are still active and who develop arrhythmia as a consequence of a viral infection. Do they have a higher risk on sudden death? Hypothesis: a) We will notice a regression of the heart muscle "mass" over a period of 4 years after the sports training was stopped, but the heart size remains larger compared to the heart size of a control population b) Some endurance athletes develop malign arrhythmia and have a higher risk on sudden death. c) Overtraining can be detected early by measuring cathecholamines and subsequently we can take action preventively to avoid serious cardiac damage by latent myocarditis. Methods Different paramters and examinations wil be planned and executed on certain points of time: biometric profile, bicycle exercise testing, ECG, echocardiogram, cardiac Doppler, questionnaire concerning the physical activity MR of the heart, MIBI/SPECt of the heart, Holter, analysis of the levels of cathecholamines in the urine.
