Participants of the Be-MaGIC-Study 2009 |
Physical activity is associated with health benefits. Acute prolonged and strenuous exercise, i.e. Marathon running, leads to hemodynamic, endothelial and myocardial functional changes. Whether these myocardial, endothelial and hemodynamic changes can also develop and persist through repetitive extreme and prolonged physical activity is currently still a matter of controversy. In addition, it is not known whether adaptations and changes over time can develop into clinically relevant cardiovascular events with negative health consequences in healthy athletes. The aim of this study is to detect exercise-induced physiological changes (inter alia of the cardiovascular system) induced by repetitive ultra-endurance strain over a period of 10 years.
For this purpose, 277 male participants from the Be-MaGIC study (Marathon 2009) are examined in this prospective observational study. A single examination with the following components will take place: Anthropometry, clinical examination, laboratory, resting / exercise electrocardiography cardiopulmonary stress test, echocardiography, and fundus camera. Further examinations will be conducted in participants with abnormal examination results in line with current clinical recommendations.

Estimated Primary Completion Date : | March 2020 |
Estimated Study Completion Date : | December 2020 |
- Changes of right ventricular systolic function (RV-EF) [ Time Frame: 10 years ]Echocardiography
- Changes in left ventricular ejection fraction (LV-EF) [ Time Frame: 10 years ]Echocardiography
- Changes in left ventricular diastolic function (E/e´) [ Time Frame: 10 years ]Echocardiography
- Change in cardiac markers (e.g. cardiac Troponin) [ Time Frame: 10 years ]Clinical chemistry (blood samples)
- Change in inflammation markers (e.g. C-reactive Protein) [ Time Frame: 10 years ]Clinical chemistry (blood samples)
- Change in microcirculation (e.g. arteriolar-to-venular ratio) [ Time Frame: 10 years ]Static Retinal Vessel Analyzer
- Change in macrocirculation (e.g. Intima media thickness) [ Time Frame: 10 years ]Carotid sonography
- Change of prevalence of cardiovascular diseases [ Time Frame: 10 years ]Questionnaire
- Association between changes of aforementioned parameters (see Topics 1-8) and potential underlying causes (e.g. sports history like number of ultraendurance competitions) in the examined cohort [ Time Frame: 10 years ]
