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 .

Local Versus Systemic Mechanisms Underlying Supervised Exercise Training for Intermittent Claudication
The mechanisms by which exercise training improves intermittent claudication remain unclear . In this article , the effects of local and systemic physiological factors on improved exercise tolerance after a supervised exercise program in claudicants are investigated . A total of 60 patients were r and omized to 3 months of supervised exercise followed by 3 months of unsupervised exercise , or to exercise advice alone ( control ) . Supervised exercise increased both pain-free and maximal walking distances . Heart rate during submaximal exercise and resting mean arterial pressure were lower after supervised exercise at 6 months . Serum lactate at maximum claudication increased significantly after 3 months in the supervised exercise group but this change had resolved by 6 months . Symptomatic improvement was accompanied by modest reductions in mean arterial pressure and submaximal heart rate on exercise . Increased serum lactate at maximum claudication subsequently declined despite continued improvement in walking distance , suggesting local adaptations to improve efficiency of muscle oxygen delivery and /or utilization
