Metabolic Dysfunction-Associated Steatotic Liver Disease
Conditions
Brief summary
This is a single-center, randomized, parallel controlled study to explore the effects of aerobic exercise, resistance exercise or aerobic combined resistance exercise on liver lipid in patients with MASLD, consisting of a 12-week core study followed by a 12-month extension phase.
Detailed description
This study was a single-center, randomized, parallel controlled clinical study. It conducted a 12-week exercise intervention for patients with MASLD, aiming to explore the effects of different exercise patterns for patients with MASLD. All subjects were randomly assigned to aerobic exercise, resistance exercise or aerobic combined resistance exercise groups. The liver lipid content was evaluated by MRI-PDFF values at baseline and 12 weeks after intervention. Liver function was evaluated by liver transaminase at baseline and 12 weeks after intervention. The degree of liver fibrosis was evaluated by MRE, LSM value and FIB-4 index at baseline and 12 weeks after intervention. The changes of body weight and body fat before and after the intervention were evaluated by Inbody-770, and the changes of muscle mass before and after the intervention were evaluated by DXA. The effects of different exercise methods on metabolic indexes were evaluated by the changes of blood glucose, glycated hemoglobin, insulin and blood lipid before and after the intervention. In addition, after the exercise intervention, this study plans to conduct a 12-month long-term follow-up.
Interventions
Intensity of exercise:Subjects conduct an aerobic exercise at 40-59% heart rate reserve(HRR). Time of aerobic exercise:from 30 to 45 minutes each day, five days a week.
The resistance exercise was consisted of equipment trainings and body weight trainings. Participants are required to exercise 3 times a week. Intensity of equipment trainings: 70% 1-RM. Exercise volume: 15-20 repetitions for a set, from 2 sets to 4 sets gradually. Body weight trainings: 15-30 repetitions for a set, from 2 sets to 4 sets gradually.
Subjects conduct both aerobic and resistance trainings. Details of aerobic training session: Subjects conduct an aerobic exercise at 40-59% heart rate reserve(HRR) from 50-55 minutes each day, 3-4 days a week. Details of resistance training session: The resistance exercise was consisted of equipment trainings and body weight trainings. Participants are required to exercise 2 times a week.

Study design
Masking description
Because of the nature of the exercise interventions, participants and exercise physiologists responsible for intervention delivery cannot be masked to group assignment. The trial will therefore use an open-label intervention design with masked outcome assessment and masked statistical analysis. Intervention delivery and outcome assessment will be performed by separate study teams. Exercise physiologists may collect intervention-related information, including attendance, exercise dose, adherence, protocol deviations, and safety events, but will not perform the prespecified primary or secondary outcome assessments. Baseline assessments will be completed before group allocation. Postintervention outcome assessments will be performed by trained assessors who are independent of the intervention team and masked to group assignment. Participants will be instructed not to disclose their assigned intervention to outcome assessors.
