Physiological effects of various types of exercise training on the indicators of NAFLD: A review study

Non-alcoholic fatty liver disease (NAFLD) is characterized by fat deposition in hepatocytes and if left unchecked might cause fibrosis, cirrhosis, and liver cell destruction. NAFLD usually does not cause any symptoms at first however If progressed, it could be accompanied by fatigue, pain, discomfort in the upper abdomen, etc. It is more common in the elderly, diabetics, and obese people. Common treatments for this disease include lifestyle modification, diet, exercise, surgery, and liver transplantation; Among these, exercise is the most effective intervention for the prevention and treatment of this disease. This study aimed to compare the effect of various sports activities on NAFLD.The related literature was collected in databases including Google Scholar, PubMed, Science direct, and Magiran between ۲۰۱۰ and ۲۰۲۰. Keywords include Obesity, Fatty liver, Non-alcoholic fatty liver disease, Physical activity, and NAFLD.Increased physical activity leads to an improvement in serum liver enzymes, reduced hepatic fat, and a reduced NAFLD grade in some cases. All four types of exercise; aerobic, resistance, HIIT, and combined have beneficial effects in people with NAFLD however through different mechanisms. However, the combined exercise seems more effective than others.Therefore, physical activity is currently known as one of the non-pharmacological tools of treatment for people with NAFLD. While some study reported the benefits of physical activity in the absence of weight loss, some have linked this benefits to a gradual weight reduction in NAFLD patient. Regardless of the type of exercise, NAFLD patients should participate in regular physical activities to improve their condition.
