Interventions

Procedure/Surgery : The aerobic exercise program consists of a treadmill fast walking exercise three times a week for 8 weeks. Exercise intensity determines the target heart rate according to the Karv

of the spare heart rate according to the Karvonen formula, then walk with 70 ~ 85&#37

of the spare heart rate for 8 minutes with the 3 interval. The interval is 3 minutes apart and progresses to 50 ~ 70&#37

of the spare heart rate. Finally, the finishing exercise should be performed at 50 ~ 70&#37

of the spare heart rate, and it will take a total of 50 minutes. After 6 weeks, in the HAIT group, preparatory exercise performs 50-70&#37

of the maximum heart rate for 5 minutes, and exercises the walking at 85-90&#37

of the maximum heart rate for 4 minutes with 5 intervals. During the interval period, exercise is performed at 60&#37

of the maximum heart rate for 3 minutes. Finally, the finishing exercise should be performed at 50 ~ 70&#37

of the spare heart rate, and it will take a total of 42 minutes. The LPT-HAIT group will be divided into Period I and Period II for 3 weeks each for 6 weeks, and exercise training will be performed b

of the maximum heart rate
