The limit of physiological adaptation of the right ventricle to endurance training

Abstract

The study aims to conduct a review of right ventricle, measured by echocardiography or magnetic resonance imaging, in athletes with high dynamic component and moderate static, the limit of the physiological adaptation. A search was carried out in the Medline database up to the end of 2017. This study showed that the mean values for the different measurements of the right ventricle in athletes are significantly greater than that of sedentary controls. In two of the 12 studies that analyzed mean diameter of the right ventricle in apical 4C, including 1477 endurance athletes and 498 controls, with high heterogeneity. Endurance athletes presented significantly higher longitudinal diameter of the RV in apical absolutes scores compared to control. The end diastolic volume and end systolic volume measured by magnetic resonance imaging, showed a significant standardized mean difference favoring athletes with a moderate heterogeneity.
