High Intensity Interval Training and Its Influence on Body Fat Parameters Among Obese Population: A Scoping Review

Abstract

Introduction: Obesity is the primary contributor to various mortality-associated disorders, including myocardial infarction and stroke. An unhealthy lifestyle and dietary habits contribute to this metabolic disorder. Moreover, it facilitates the onset of additional conditions, including diabetes mellitus and hypertension. Due to its intensity, High Intensity Interval Training (HIIT) is better appropriate for obese individuals

Objectives: To find the effectiveness of HIIT on body fat parameters in obese population by reviewing and analysing the evidences.

Methods: We performed a search for publications and evidence specifically addressing the correlation between HIIT and obesity, utilizing randomized controlled trials from several sources including Google Scholar, PubMed, and periodicals pertaining to obesity. We performed a comprehensive analysis of the efficacy of HIIT training by evaluating the pre- and post-intervention values seen in randomized controlled trials (RCTs). After comprehensive review, we picked nine publications as suitable for our study

Results: Of the 9 publications, 7 evidenced the efficacy of HIIT exercise in diminishing body fat, whilst 2 shown minimal influence on body fat metrics within the obese group.

Conclusions: We ascertain that HIIT is efficacious for the obese demographic in diminishing body fat, and this study may assist future researchers in selecting and formulating the suitable HIIT procedure.
