Individualized vs. group exercise in improving quality of life and physical activity in patients with cardiac disease and low exercise capacity: results from the DOPPELHERZ trial
Abstract Purpose : Important goals of cardiac rehabilitation maintenance programs ( CMP ) are to increase leisure time physical activity ( LTPA ) and improve health-related quality of life ( HRQoL ) . Elderly patients with cardiac disease and low exercise capacity are simultaneously the most severely affected and have the most to gain from exercise-based rehabilitation . Individualized combined exercise ( ICE ) may be an effective modality to achieve these goals . We compared six months of ICE to CMP in their effects on LTPA and HRQoL. Methods : Sixty patients ( 70 ± 9 years , 39 % female ) with cardiac disease and low exercise capacity ( < 6 MET ) were r and omly allocated to six months of once-weekly ICE or CMP . The patients in ICE performed moderate endurance and resistance exercise on machines , based on intensities from individual peak exercise testing . Patients in CMP performed weekly sessions of calisthenics , flexibility , coordination and relaxation activities . LTPA and HRQoL were assessed with accelerometry and question naires at baseline and six months . Results : Sixty patients completed the trial . ICE  increased vigorous PA ( ICE : Δ + 12 MET-min/d , CMP : Δ –5 MET-min/d , p = .02 ) and steps per day ( ICE : + 1586 steps/d , CMP : –838 steps/d , p < .01 ) compared to CMP after six months . ICE significantly improved in several components of HRQoL ( vitality , emotional health , social health , positive and negative affect ( all p < .05 ) compared to CMP . Conclusions : ICE result ed in significant improvements in physical activity levels and health related quality of life in moderate to high-risk patients compared to CMP . Implication s for rehabilitation Relatively low volumes and intensities of exercise may lead to substantial improvements in both physical activity levels and health-related quality of life Exercise modes in cardiac rehabilitation maintenance programs should not be limited to calisthenics and large group-based exercise Supplemental resistance exercise may improve health-related quality of life and increase physical activity levels in patients with low exercise capacity Moderate to high-risk elderly patients also benefit from individualized endurance-resistance
