Training-induced right ventricular remodelling in pre-adolescent endurance athletes: The athlete's heart in children

Endurance training influences the growing heart of male preadolescent athletes with an addictive increase in RV dimensions, with a preserved RV function. Therefore, in children engaged in endurance sports the increase in RV size associated with normal RV function represents a physiological expression of the athlete's heart and should not be misinterpreted as an expression of incipient RV cardiomyopathy.
