High-Intensity Interval Training Early After Left Ventricular Myocardial Infarction

High-intensity interval training (HIIT) is performed on a cycle ergometer. It consists of a 10 min warm-up followed by 4 min intervals in Zone III (at 90-95% of peak heart rate), with each interval separated by 3 min of active pauses in zone I (at 50-60% of peak heart rate). The total duration of the HIIT training is 38 min.

MICE is also performed on a cycle ergometer at an intensity of 50-80% of peak VO2 or 60-75% of peak heart rate for 47 min (in order for the two training protocols to be isocaloric). The control group will perform MICE training three times per week.
