The application of High Intensity Interval Training (HIIT) was presented as an alternative to Moderate Intensity Continuous Training (MICT) with promising results in rehabilitation of patients with chronic heart failure with reduced ejection fraction (CHFrEF). These protocols mainly assessed aerobic capacity, left ventricular ejection fraction (LVEF) and quality of life (QoL), considering adherence and safety in the exercise. The main objective of this study is focused on conducting a comprehensive systematic review on the efficacy of HIIT versus MICT in patients with CHFrEF associated with the improvement of the variables analysed for the well-being of the subjects. The search for randomized clinical trials (RCTs) was carried out in Medline and ScienceDirect databases, with a search equation and established inclusion and exclusion criteria, in the last 10 years. Twelve studies with a total sample of 843 patients were included. The articles analyzed showed that, despite the fact that in most of the RCTs there were no significant differences between the application of HIIT or MICT to improve aerobic capacity, LVEF and QoL, there are some in which the data seem to indicate a benefit in aerobic capacity in the use of HITT vs MICT in patients with CHFrEF. Both training protocols showed high adherence and adequate safety. These conferred similar QoL benefits in the patients.
