Why the study?
International consensus was lacking regarding the prescription of high-intensity interval training for patients with coronary artery disease attending cardiac rehabilitation.
Does low-volume high-intensity interval training improve cardiorespiratory fitness compared to moderate-intensity steady-state exercise in patients with coronary artery disease attending cardiac rehabilitation?
Population
382 patients with CAD from 6 outpatient CR centres
Comparison
Twice-weekly low-volume HIIT vs moderate-intensity steady-state exercise
Design
Multi-centre randomized controlled trial
Follow-up
8 weeks

Supports low-volume HIIT in CAD cardiac rehabilitation; extends RCT evidence for its use over moderate-intensity training.
Does low-volume high-intensity interval training improve cardiorespiratory fitness compared to moderate-intensity steady-state exercise in patients with coronary artery disease attending cardiac rehabilitation?
Low-volume HIIT is a safe and effective alternative to moderate-intensity steady-state exercise that produces superior short-term improvements in cardiorespiratory fitness for patients with stable CAD in cardiac rehabilitation.
