Influence of High-Intensity Interval Training Versus Continuous Training on Functional Capacity in Individuals With Heart Failure

Abstract

Introduction: Cardiac rehabilitation programs reduce the risk of death and acute events related to the disease through the association of various modalities of exercise. When implemented in high-intensity interval training (HIIT) programs, it may allow for gradual adaptation of the skeletal muscles to greater exercise intensities. The present systematic review aimed to determine whether HIIT promoted a greater increase in exercise tolerance in comparison with continuous aerobic training in individuals with heart failure. Methods: A systematic search for articles indexed in the PubMed/MEDLINE, LILACS, SciELO, PEDro, Scopus, and Web of Science databases was carried out. The descriptors used for the search followed the description of the MeSH/DeCS terms with no language or year of publication restrictions. When possible, a meta-analysis was performed and the quality of the evidence was evaluated using the GRADE scale. Results: The broad search strategy resulted in 5258 titles, and a total of 7 articles were included in the qualitative synthesis. A low quality of evidence was observed demonstrating that interval training is superior to continuous aerobic training for improving peak oxygen uptake, which reflects an increase in functional capacity of these individuals and moderate quality of evidence regarding improved quality of life and left ventricular ejection fraction. Conclusion: High-intensity interval training and continuous training provide benefits for patients, however, the quality of evidence still does not allow us to indicate whether there is a superiority of HIIT over conventional continuous exercise training using the variables analyzed.

“…It is recommended that all patients with established CHF (regardless of left ventricular ejection fraction) should be enrolled in an exercise-based cardiac rehabilitation programme with a multi-faceted approach 3,48-51 ( Table 5) [52][53][54][55][56][57][58][59][60][61][62][63][64][65][66][67] . This may also apply to patients with cardiac implantable electronic or ventricular assistant devices.…”

“…Training intensity, frequency and duration should be tailored to each patient's clinical status, stress tolerance and comorbidities. Training intensity should be determined on the basis of the one The quality of existing evidence does not allow us to indicate whether there is a superiority of HIIT over conventional continuous ET for improving VO 2peak , LV function and QoL54,55 Limited information is available on different ET type combinations.…”

“…In fact, there is a trend that indicates that health indices and markers are more favourable after HIIT than after MICT [26]. Otherwise, this is still not clear regarding other functional parameters [32,33,34].…”

“…We were able to test 15 -2 ). The boys and girls did not differ signi cantly from each other with respect to age or anthropometric variables.…”

“…The intensity for the high-intensive bursts is described as "all-out", "maximal effort", "³90% VO 2 peak", "85 -95% HR max", or "³100% maximal aerobic speed" [14]. MICT on the other hand consists mainly of aerobic exercise training performed continuously or in intervals [15]. The training modality which shows the most promising effects for improving CRF in children, adolescents and adults is High-Intensity Interval Training (HIIT) [14,16].…”
