Adaptación de la aorta al entrenamiento. Perspectiva fisiológica

The damping of the blood pressure oscillations makes the aorta an “extension” of the ventricular systolic function. This function is even more evident during endurance exercise, with an increase in the ejection index of 4 times the resting values. Similarly, as a result of training, an adaptation occurs in cardiac morphology, in which the aorta undergoes a change in its structure that allows for better damping function. Athletes that adapt more may experience both of the heart chambers and the aorta, are those who demand a high cardiovascular stress, a high dynamic component and moderate static component. By using non-invasive measurements in humans (mainly echocardiography and MRI), the size of the aorta has been shown to increase in athletes with greater cardiovascular demands.
