Cardiac Remodeling in Response to 1 Year of Intensive Endurance Training.

CONCLUSIONS: -One year of prolonged and intensive endurance training leads to cardiac morphologic adaptations in previously sedentary young subjects similar to those observed in elite endurance athletes; however it is not sufficient to achieve similar levels of cardiac compliance and performance. Contrary to conventional thinking, the left ventricle responds to exercise with initial concentric not eccentric remodeling during the first 6-9 months after commencement of endurance training depending on the duration and intensity of exercise. Thereafter, the left ventricle dilates and restores the baseline mass to volume ratio. In contrast, the right ventricle responds to endurance training with eccentric remodeling at all levels of training.
