About this trial

High-intensity interval training (HIIT), as an individualized exercise training mode based on cardiopulmonary exercise testing (CPET), is characterized by high-intensity training sessions interspersed with short rest periods. The findings from recent trials suggest that in the management of metabolic dysfunction-associated fatty liver disease (MAFLD), compared with traditional aerobic exercise modes such as moderate-intensity continuous training, HIIT may achieve similar or even better effects in reducing liver fat content, increasing peak oxygen uptake, improving insulin resistance, and lowering blood pressure, despite requiring less time commitment and lower energy expenditure. However, there is currently no consensus regarding the formulation of HIIT exercise protocols.

Based on the lower limits of the current mainstream HIIT intensity, sets, and interval time parameters, this study aims to assess the effectiveness, safety, and feasibility of the current exercise prescription in improving MAFLD.
