Evidence for the effects of high intensity intermittent training (HIIT) on adipose tissue in overweight or obese subjects with or without comorbidities: A systematic review

Abstract

High intensity interval training (HIIT) is a training that seems to have effects on the variance of adipose tissue through its protocols in overweight and obese adult population, but this variance is not entirely clear. Objective: to know the results are the effects of HIIT on adipose tissue in overweight or obese people with or without comorbidities. Material and method: Those articles that met the search phrase were considered, and only those that met the following inclusion criteria were selected: a) clinical trials or randomized controlled trial, b) studies conducted in overweight or obese adults, with or without comorbidities c) multilanguage studies, d) studies published between 2016 and 2021, f) articles classified in quartile 1, 2 or 3, e) articles where the intervention is applied to humans f) free access articles. Exclusion criteria: a) narrative reviews were systematic reviews or meta-analyzes, b) studies applied to children, adolescents and the elderly c) articles that are not indexed. The search for articles in the databases yielded a total of 2561 results (Pubmed = 48 and Science Direct = 2513) in a period of time from August to October 2021, articles were selected by title and / or Abstract, when applying the Inclusion and exclusion criteria, a total of 5 original articles were obtained. Result: the results show variance towards the decrease in adipose tissue, showing that HIIT is a favorable and applicable tool in the overweight and obese population. Conclusion: The information collected shows the enhancing effects of physical training and its favorable effects on the reduction of adipose tissue. Faced with this, HIIT is presented as a useful non-pharmacological and low-cost alternative, which, when applied, controlled and adapted correctly, amplifies its beneficial effects.
