title: Much potential but many unanswered questions for high-intensity intermittent exercise training for patients with heart failure.
abstract: There is a robust trove of scientific studies that support the positive physical and mental health benefits associated with aerobic exercise for healthy individuals. These recommendations suggest that more vigorous exercise can be performed on fewer days for the same benefit. High-intensity intermittent exercise (HIIE) training has begun to show promise. HIIE seems safe and improves physiology, quality of life, and functional capacity. This review defines HIIE, discusses its physiologic benefit for patients with heart failure, outlines the studies that have been conducted to date, and places it in the context of the current clinical environment of exercise training for these patients.
