In Taiwan, with the westernization of eating habit and lifestyle, metabolic syndrome and non-alcoholic fatty liver (NAFLD) have become very important health issues. This project will therefore study the histological and clinical data of patients with non-alcoholic fatty liver disease and explore the impact of exercise intervention on the hepatic fatty infiltration of the patients. The research strategy will include (1) combining modern artificial big data collection technology to fully monitor the daily life, sleep and exercise patterns of the participants; (2) improving fatty liver and metabolic syndrome through trial-based exercise intervention; and (3) exploring the changes of sleep patterns and intestinal microflora in patients with metabolic liver disease after exercise intervention.

Background & aims: In Taiwan, with the investigators sternization of eating habit and lifestyle, metabolic syndrome and non-alcoholic fatty liver (NAFLD) have become very important health issues. This project will therefore study the histological and clinical data of patients with non-alcoholic fatty liver disease and explore the impact of exercise intervention on the hepatic fatty infiltration of the patients. The research strategy will include (1) combining modern artificial big data collection technology to fully monitor the daily life, sleep and exercise patterns of the participants; (2) improving fatty liver and metabolic syndrome through trial-based exercise intervention; and (3) exploring the changes of sleep patterns and intestinal microflora in patients with metabolic liver disease after exercise intervention.

Materials & methods: The investigators will first retrospective collect clinical and histologic data of patients with biopsy proven NAFLD. Second, the investigators will establish a non-invasive fatty liver detection and staging platform at National Taiwan University Hospital. The investigators then plan to enroll 100 patients with non-alcoholic fatty liver from NTUH employees. The investigators will collect all basic information including intrahepatic fat and fibrosis severity, and assign them to the exercise intervention group (n = 80) and the observation group (n = 20) after conditional screening. After one year of exercise intervention, the investigators will analyze the effect of exercise on intrahepatic fat (main parameter: 20% reduction in intrahepatic fat; 30% achieved in the exercise intervention group; 5% achieved in the control group) and related metabolic syndrome indicators, and analyze different types of exercise Whether the intervention has different effects, and analyze the improvement of sleep pattern and intestinal microflora after exercise intervention.
