Key result
Circuit training in patients with chronic heart failure resulted in similar oxygen consumption and hemodynamic demand compared to continuous aerobic exercise, with lower systolic blood pressure (P<0.05).
Why the study?
Does combined aerobic and resistance circuit training produce similar exercise intensity and oxygen consumption compared to continuous aerobic exercise in patients with chronic heart failure?

May support circuit training as feasible option in chronic HF; leaves open larger trials on outcomes.
Does combined aerobic and resistance circuit training produce similar exercise intensity and oxygen consumption compared to continuous aerobic exercise in patients with chronic heart failure?
Circuit training is well-tolerated and elicits similar oxygen and hemodynamic demands as continuous aerobic exercise in patients with chronic heart failure, with RPE being a better monitor of intensity during circuit training.
Green et al. (2001) studied Chronic heart failure (CHF) (n=6). Combined aerobic and resistance exercise (circuit training) vs. Continuous cycling on a bicycle ergometer (aerobic exercise) was evaluated on Ambulatory oxygen consumption (VO2), rate of perceived exertion (RPE), heart rate, and hemodynamic responses. Circuit training in patients with chronic heart failure resulted in similar oxygen consumption and hemodynamic demand compared to continuous aerobic exercise, with lower systolic blood pressure (P<0.05).
