Impact of exercise training duration on obesity and cardiometabolic biomarkers: a systematic review

Introduction Physical exercise deters the risk and reduce the adjusted Odds Ratio related to obesity and cardiometabolic diseases but the amount of physical exercise required for initiating those potential advantageous developments in the human body for normal obese individuals is still debatable and thus made many face the health burden during pandemic, despite of their claiming to be physically active. Objective The primary aim of this review was to find an ideal duration and form of exercise that could help reduce the risk of cardiometabolic diseases and its complications for subjects with obesity and deranged cardiometabolic risk markers. Method Electronic database PubMed/MedLine, Scopus and PEDro for available literature on Experimental studies and RCT on exercise prescription and its effect on anthropometric measurements as well as key biomarkers in obese individuals, 451 records were procured, 47 full text articles were identified to assess eligibility criteria out of which 19 were finally included in the review. Results There exists a strong association between cardiometabolic profile and physical activity, poor diet, sedentary lifestyle and continuous exercises for longer duration can lead to reduction in obesity and subjects with cardiometabolic diseases. Conclusion Various confounding factors that may affect the outcome of physical activity training have not been considered in a standard format by all the authors in the articles reviewed. There was variation in duration of physical activity and energy expenditure required for inducing the changes in different cardiometabolic biomarkers.
