Brief summary
The uncertainty concerning the onset and the extent of cardiac remodeling in response to intensive training hinders medical evaluation by physician. A better knowledge of the physiology of cardiac adaptation to training will enable physicians to correctly determine whether observed patterns of cardiac remodeling are physiological or pathological. This prospective study proposes to assess in a trained-athlete population the cardiac remodeling in response to intensive exercise training. This study is observational, we do not interfere with athlete's training.
Interventions
We retrieved all electrocardiograms and echocardiography made during the clinical examination of each athlete and each sedentary control. * Standard 12 lead ECG * Trans-thoracic echocardiography examination of cardiac function, morphology and intracardiac flow.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Evaluation of ventricular response to exercise training by echocardiography. | Day 1 | 1. 2D- morphological and functional parameters of both left and right ventricles: * end-diastolic and end-systolic dimensions (cm) * left ventricular mass (g) * ventricular end-diastolic and end-systolic areas (cm²) * ventricular ejection fraction (%) * atrial volumes (ml) * diastolic indices by pulsed wave Doppler and tissue Doppler (cm/s) * myocardial deformation by speckle tracking (%) 2. 3D- morphological and functional parameters of both left and right ventricles: * ventricular full volumes (ml) * ejection fraction (%) 3. Intracardiac flow measurements by color Doppler M-mode: estimation of intra ventricular pressure gradients between the base and the apex (mmHg). |
