The acute physiological response to high-intensity interval exercise in patients with coronary artery disease

Abstract: High-intensity interval exercise (HIIE) elicits quicker and more substantial improvements in aerobic capacity compared to moderate-intensity continuous exercise (MICE), but the protocol that optimizes the physiological stimulus and patient preference is undetermined. Fifteen patients with coronary artery disease (CAD) underwent physiological assessment during 3 different HIIE protocols and MICE. The 4x4 protocol elicited a greater physiological stimulus, as indicated by heart rate (HR), oxygen uptake (VO2), rating of perceived exertion (RPE), and blood pressure responses, but was the least preferred HIIE protocol. The 10x1 protocol was most preferred, it was comparable to MICE, and should be considered a timesaving alternative. TRIP proved to be a strong physiological stimulus and may be a viable choice opposed to long duration intervals, for its similar HR response and RPE at a higher VO2 compared to MICE. These results indicate that HIIE is an efficient and well-tolerated exercise prescription for CAD patients.
