The role of physical exercise in treating people with nonalcoholic fatty liver disease

Objectives: This study aimed to investigate the role of exercise training programs in the prevention and management of non-alcoholic fatty liver disease (NAFLD).Method: the literature review was conducted from January 1, 2020, using the web of science, SCOPUS, and PubMed. Comprehensive exploration was performed with keywords (exercise, NAFLD, liver, and hepatic diseases). Published researches and studies which collected from the exploration were reviewed. Unclear studies were ignored. Results: Many exercise programs were recognized. Most documents confirm a decrease in the fatty liver index, alanine transaminase (ALT), hepatic lipid content, intrahepatic triglyceride (IHTG), improving insulin sensitivity and improving cardiorespiratory fitness. Conclusions: Despite the variations of exercise programs may be adjusted to manage NAFLD, the present review on this issue is restricted in extent. Future studies have to be carried out to strictly clarify which of these changes in daily living may improve obesity-related to NAFLD.
