Biventricular Response of the Heart to Endurance Exercise Training in Previously Untrained Subjects

Biventricular Response of the Heart to Endurance Exercise Training in Previously Untrained Subjects

Background Functional adaptation of the heart to regular strenuous exercise has not been fully elucidated yet, with different patterns of alterations being reported. We evaluated the effect of endurance exercise training (EET) on left (LV) and right ventricular (RV) mechanics in amateur individuals...

Zusammenfassung:Background Functional adaptation of the heart to regular strenuous exercise has not been fully elucidated yet, with different patterns of alterations being reported. We evaluated the effect of endurance exercise training (EET) on left (LV) and right ventricular (RV) mechanics in amateur individuals preparing for triathlon competitions. Methods Twenty‐one subjects aged 33 ± 6 years underwent conventional and speckle tracking echocardiography at rest before and after a high‐intensity (12.3 ± 1.0 h/week) 12‐month EET. Results At follow‐up, in addition to the improvement in LV diastolic parameters, a significant decrease in longitudinal (26.0 ± 3.3% vs. 24.3 ± 3.2%, P
