      <i_freetext>Intervention 1: Intervention group: 1 High-intensity interval training group: Participants will perform 60-minute stationary exercises for 12 weeks, 3 sessions per week, including a 10-minute warm-up, 40-minute HIIT session, and 10-minute cool-down. The intensity of the exercise will be controlled using a heart rate monitor in the range of 80 to 85 percent of the subjects' maximum heart rate. Intervention 2: Intervention group: 2 groups of moderate-intensity continuous exercise: Participants will perform aerobic exercise, stationary cycling, and slow running exercises for 12 weeks, 3 sessions per week, each session lasting 60 minutes. The intensity of the exercise will be controlled using a heart rate monitor in the range of 55 to 65% of the subjects' maximum heart rate.</i_freetext>
