Key result
Low-volume high-intensity interval training improved peak oxygen uptake by a mean of 14.9% from baseline, demonstrating similar effectiveness to continuous aerobic exercise training despite a reduced time commitment.

Does low-volume high-intensity interval training improve peak oxygen uptake and functional capacity compared to continuous aerobic exercise training in patients with chronic heart failure?
Standardized Mean Difference: 0.18
Absolute Event Rate: 17.7% vs 18.9%
Low-volume high-intensity interval training is a feasible and time-efficient alternative to continuous aerobic training in heart failure patients, yielding similar improvements in exercise capacity despite a significantly lower total work volume.

Low-volume HIIT feasible in outpatient HF rehab; leaves open efficacy versus continuous training in larger trials.
Koufaki et al. (2014) conducted an RCT in chronic heart failure (n=17). Low-volume high-intensity interval training vs. Continuous aerobic exercise training was evaluated on Peak oxygen uptake (VO2peak) (Adjusted ES 0.18). Low-volume high-intensity interval training improved peak oxygen uptake by a mean of 14.9% from baseline, demonstrating similar effectiveness to continuous aerobic exercise training despite a reduced time commitment.
