Interest of APA in Fatty Liver Disease Evaluation of Efficacy and Adherence to an Adapted Physical Activity (APA) Program in Patients With Metabolic Fatty Liver Disease

Non-Alcoholic Fatty liver Disease (NAFLD) is a Public Health problem. NAFLD affects nearly 25% of the world's population. NAFLD includes hepatic complications related to insulin resistance and metabolic inflammation. NAFLD is in fact a continuum of liver abnormalities that progresses from pure steatosis, to Non-Alcoholic Steato-Hepatitis-NASH, then to hepatic fibrosis, cirrhosis and even the appearance of primary liver cancer (hepatocellular carcinoma). Although many drugs are being tested for advanced forms of NAFLD, steatohepatitis (NASH) with fibrosis and post-NAFLD cirrhosis, there are currently no drugs with marketing authorization. Excessive and unbalanced dietary intake, excessive physical inactivity and lack of regular physical activity are major contributors to the development of NAFLD. It is therefore logical that the preventive and curative treatment of NAFLD is based on hygienic and dietary measures. Physical exercise alone in patients with NAFLD has been shown to improve liver steatosis even in the absence of weight loss. Proof of concept of the improvement in hepatic steatosis has been shown to be achieved by physical activity, whether or not associated with dietary management. More recently, APA (Adapted Physical Activity) is thus seen as a new modality of care that will become central to the prevention and treatment of NAFLD. The aim of this work is to evaluate the decrease in hepatic steatosis by continuous CAP® and parameters evaluating non-invasive inflammation and hepatic fibrosis in patients with NAFLD subjected to the application of personalized dietary measures without or with the performance of personalized and reproducible physical activity via the prescription of adapted physical activity. The evaluation will be carried out initially, at the end of the operation and 6 months after the end of the operation in order to look for a persistent effect of the modification in lifestyle.
