The Impact of Different Exercise Modes on Bile Acid Levels and Liver Function in Patients With Non-alcoholic Fatty Liver Disease

An exercise program was developed by a full-time physical education teacher, with all group exercises conducted at the outdoor track and field facility of Xuzhou Medical University. Participants in the aerobic training group, after completing a warm-up, were required to perform moderate-intensity aerobic running for 60 minutes per session, 4-5 times a week. The exercise intensity was set to reach 50%-70% of the maximum heart rate (Maximum heart rate = 220 - age). The exercise sessions were scheduled in the evening after dinner, from 17:30 to 19:00.All participants were continuously intervened for 8 weeks.

Participants in the resistance training group were required to complete moderate-intensity resistance exercises 4-5 times per week. Each session included a warm-up, followed by exercises such as knee lifts with torso twists, knee-to-hand taps under the hips, jumping jacks, burpees, sit-ups, planks, and squats. The routine was structured to perform 5-6 exercises per session, with 6-8 repetitions for each set. There was a 30-second rest interval between sets, and the total exercise time was 60 minutes. The timing for these exercise sessions was the same as for the AT group, conducted in the evening after dinner.All participants were continuously intervened for 8 weeks.

Participants in the combined aerobic and resistance training (AT+RT) group started their sessions with a warm-up, followed by 30 minutes of aerobic running. After the aerobic training, they engaged in resistance training. The resistance training regimen was the same as that for the RT group, except that the duration of the resistance training was shorter. The total duration of the exercise session was 60 minutes.All participants were continuously intervened for 8 weeks.
