Study of the Aorta Adaptations to Exercise in Triathletes During Sports Season (CoATri)

Regular sustained physical activity creates a cardiac remodelling : it is athlete's heart. In our preliminary work published in 2016, the investigators demonstrated in a small population of triathletes that there is also a vascular remodelling named athlete's artery. Moreover, the investigators know that left ventricle and aorta behave together like a couple. So they want to study by Cardiovascular Magnetic Resonance Imaging the impact of triathlon on the cardiac AND aortic remodelling.
