[Exercise test in athletes].

The particularities of exercise tests in athletes concern mainly the exertion protocols adapted to their increased physical capacities and the interpretation of ECG tracing which can sometimes be very special at rest and also misleading during exercise. In the great majority of cases, the test used is both cardiac and pulmonary, in order to assess the aerobic capacities, the maximal aerobic power, and the determination of ventilation thresholds (programming and follow-up of training...). More infrequently, the test is used to detect cardiovascular diseases, especially during a longitudinal follow-up of high-level athletes, or to exclude it in case of cardiovascular symptoms, atypical resting ECG or even in case of suspicion of disease (arrhythmia, cardiac chamber hypertrophy or dilation at echocardiography). In more aged sportsmen (athletes masters), exercise tests performed are usually required for screening coronary heart disease. In this case the test protocols should be more adapted for screening than for the assessment of sportive capacities.
