The intervention group received 12 weeks of continuous remote intervention combined with health education. The control group only received 12 weeks of continuous health education, and the content and frequency were the same as those of the management group. Both groups received instruction at the beginning of the intervention. The intervention group was given priority to continuous walking/running combined with aerobic exercise and swimming. Five to seven sessions per week for 45 minutes each session. Acclimatizations were performed at an intensity of 40%-49% reserve oxygen uptake (VO2R) from weeks 1 to 4, and exercise was performed at an intensity of 50%-59% VO2R from weeks 5 to 12. 5 minutes each of preparation and grooming activities (including joint movement and stretching) for each exercise. Combined with incremental load resistance exercise 2-3 times a week, 8 movements, 2-3 groups each time, repeated 8-10 times/group, with a 2-min rest between groups. The heart rate, RPE (12-13, "fairly easy" to "somewhat laborious") and exercise bracelet were used to monitor the intensity and amount of exercise. The exercise intervention was usually delivered 1-2 h after a meal. The daily medical supervision in the process of management implementation was carried out by trained sports managers through the doctor terminal of "exercise assistant" to collect and monitor the data of the study subjects.
