AbstractBackgroundSedentary aging has deleterious effects on the cardiovascular system, including decreased left ventricular compliance and distensibility (LVCD). Conversely, Masters level athletes, who train intensively throughout adulthood, retain youthful LVCD.ObjectivesThe purpose of this study was to test the hypothesis that preservation of LVCD may be possible with moderate lifelong exercise training.MethodsHealthy seniors (n = 102) were recruited from predefined populations, screened for lifelong patterns of exercise training, and stratified into 4 groups: “sedentary” (<2 sessions/week); “casual” (2 to 3 sessions/week); “committed” (4 to 5 sessions/week); and “competitive” Masters level athletes (6 to 7 sessions/week). Right heart ca...
