Effects of Aerobic Physical Training in Non-Alcoholic Fat Hepatic Disease Aspects Related to Mitochondrial Biogenesis and Oxidative Stress: A Review

Abstract

Non-alcoholic fatty liver disease (NAFLD) is one of the most common forms of liver disease, affecting about 20% to 30% of the adult population, being found more often in obese individuals (~ 90%). Among the main etiological factors are insulin resistance, mitochondrial dysfunction and oxidative stress. To date, no specific pharmacological treatment for NAFLD, so lifestyle modifications such as: reduction in body weight, diet and regular practice of aerobic physical exercise are effective, however it is not yet elucidated what the main impacts of physical exercise on NAFLD.
