SET was still beneficial for maximal and pain-free walking distances at 12 months , but it did not have a significant effect on quality of life parameters .
AUTHORS ' CONCLUSIONS SET has statistically significant benefit on treadmill walking distance ( maximal and pain-free ) compared with non-supervised regimens .
BACKGROUND Although supervised exercise therapy is considered to be of significant benefit for people with leg pain ( peripheral arterial disease ( PAD ) ) , implementing supervised exercise programs ( SETs ) in daily practice has limitations .

OBJECTIVES The main objective of this review was to provide an accurate overview of studies evaluating the effects of supervised versus non-supervised exercise therapy on maximal walking time or distance on a treadmill for people with intermittent claudication .
The effect of exercise intensity on the response to exercise rehabilitation in patients with intermittent claudication.
PURPOSE The purpose of this r and omized trial was to compare the efficacy of a low-intensity exercise rehabilitation program vs a high-intensity program in changing physical function , peripheral circulation , and health-related quality of life in peripheral arterial disease ( PAD ) patients limited by intermittent claudication . METHODS Thirty-one patients r and omized to low-intensity exercise rehabilitation and 33 patients r and omized to high-intensity exercise rehabilitation completed the study . The 6-month exercise rehabilitation programs consisted of intermittent treadmill walking to near maximal claudication pain 3 days per week at either 40 % ( low-intensity group ) or 80 % ( high-intensity group ) of maximal exercise capacity . Total work performed in the two training regimens was similar by having the patients in the low-intensity group exercise for a longer duration than patients in the high-intensity group . Measurements of physical function , peripheral circulation , and health-related quality of life were obtained on each patient before and after the rehabilitation programs . RESULTS After the exercise rehabilitation programs , patients in the two groups had similar improvements in these measures . Initial claudication distance increased by 109 % in the low-intensity group ( P < .01 ) and by 109 % in the high-intensity group ( P < .01 ) , and absolute claudication distance increased by 61 % ( P < 0.01 ) and 63 % ( P < .01 ) in the low-intensity and high-intensity groups , respectively . Furthermore , both exercise programs elicited improvements ( P < .05 ) in peak oxygen uptake , ischemic window , and health-related quality of life . CONCLUSION The efficacy of low-intensity exercise rehabilitation is similar to high-intensity rehabilitation in improving markers of functional independence in PAD patients limited by intermittent claudication , provided that a few additional minutes of walking is accomplished to elicit a similar volume of exercise
