The Effect of Exercise Training on Skeletal Muscle Metabolism in Peripheral Artery Disease (PAD)
2013年2月20日 更新者：Reena Pande, MD、Brigham and Women's Hospital
The Effect of Exercise Training on Skeletal Muscle Metabolism in Peripheral Artery Disease
Specific Aim 1: To test the hypothesis that subjects with PAD and intermittent claudication have altered expression of genes that regulate skeletal muscle metabolism.
Specific Aim 2: To test the hypothesis that exercise training improves calf skeletal muscle insulin resistance and genes that regulate skeletal muscle metabolic function in PAD patients with intermittent claudication.

有源比较器：Exercise Training
Subjects randomized to exercise training will participate in a three-month treadmill exercise program in 1-hour training sessions three times per week as previously described.
After a 5-minute warm-up period, exercise is initiated at a low workload of 2 mph at 0% grade.
Subjects walk until moderate claudication severity develops, and then rest until the discomfort resolves, repeating until the total exercise period is completed.
The intensity of the treadmill exercise is increased as tolerated by increasing walking speed by 0.5-1 mph and/or grade by 1-2%.
Subjects are encouraged to continue the walking program at home for at least 30 minutes on two separate occasions each week.

有源比较器：Normal routine
Subjects randomized to the routine activity control group will be asked to keep a log of their daily activities and return to the Vascular Research Center at weeks 4, 8, and 12 at which time they will be asked to return their log and undergo repeat treadmill testing and complete the 6 minute walk test.
