Rehabilitation With Exercise-Based Intervention for Nonalcoholic Chronic Hepatic Esteatosis

This study proposes a single-blind randomized clinical trial designed to evaluate the effects of high-intensity interval training (HIIT) on liver health in adults with overweight or obesity, while also assessing the usefulness of FibroScan as a tool for detecting and monitoring hepatic changes. The study is grounded in the idea that HIIT may improve liver status in individuals with metabolic dysfunction-associated steatotic liver disease, even in the absence of major weight loss, and that FibroScan could serve not only as a diagnostic method but also as a follow-up instrument during conservative treatment. The sample will include 30 adults from the Los Ríos Region, aged 18 to 59 years, with BMI \>25 kg/m² and chronic noncommunicable conditions such as dyslipidemia, diabetes, or hypertension, provided they are fit for exercise. Participants will be randomly assigned to either an interven
