Dose-Dependent Effects of Physical Exercises on Anthropometeric Parameter among Overweight/Obese Individuals: Systematic Review

Abstract

Physical Activity is primarily the central approach for maintaining the healthy weight therefore developing effective dose of physical exercises in term of intensity, duration and type is more crucial now a days. This systematic review summarizes the impact of physical exercises dose on Body weight (BW), body fat percentage (PBF) and body mass index (BMI) in individuals with overweight and obesity. From February to August 2021, a systematic literature search strategy was used, with four electronic databases yielding 2,750 records. After screening the study titles, abstracts and full texts according the eligibility criteria, we included 100 studies in our final analysis. Aerobic (endurance-based exercises) and anaerobic (strength/resistance training) both exercises with low to moderate intensities improves anthropometric characteristics in overweight/obese population from trivial to moderate effect size (0.2-1.0) ranging from eight weeks to 12-months of duration, However, combine training (High intensity circuit training/High Intensity Interval Training, HICT/HIIT) substantially decreases the BMI, BW and PBF in overweight and obese individuals from small to large effect size (0.2-1.2) ranging from three to twenty-four weeks of duration. Yet, the optimal combination of the ratio of circuit training intervals necessary to produce effective results in overweight and obese population is still ambiguous. Thus further studies are needed to determine the optimal ratio of bouts intervals to produce most efficient HICT/HITT training programs in less time.
