Abstract

This study assessed the effect of aerobic and resistance exercise training on cardiac power output and physical functional capacity in chronic heart failure (CHF). Patients with stable CHF (n = 21) were randomized either into aerobic or to a resistance exercise training group. At baseline and after 12 weeks of either aerobic or resistance exercise intervention, patients underwent maximal graded cardiopulmonary exercise testing with respiratory gas exchange and noninvasive (rebreathing) haemodynamic measurements. Peak cardiac power output increased by 6.2% following aerobic exercise only (from 2.56±0.78 to 2.72±0.61 watts). This was due to an increase in peak cardiac output by 0.8 l.min-1 (from 11.1±3.7 to 11.9±3.4 l.min-1, p<0.05). Peak oxygen consumption and anaerobic threshold increased following aerobic training (by 7.1% and 7.8% respectively, p<0.05), but not following resistance exercise. Aerobic exercise training increases maximal flow-generating capacity of the heart and delays anaerobic metabolism in CHF patients. Resistance exercise seems not to benefit maximal cardiac performance in patients with CHF.
