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 .
Increased endogenous nitric oxide production induced by physical exercise in peripheral arterial occlusive disease patients.
The effects of 14-day physical exercise or iloprost treatment ( 0.5 - 2 ng/Kg/min ) on endogenous nitric oxide production and neutrophil adhesion were evaluated in 20 patients with peripheral arterial occlusive disease ( Fontaine Stage II ) . Peripheral venous blood sample s and 4-h urine sample s were collected before , immediately after 14 days of therapy and 7 - 10 days after therapy in order to evaluate neutrophil adhesion , nitrite/nitrate and cGMP excretion rates . A longer pain free walking distance was observed after exercise , compared to iloprost ( > 500 m in 3/10 subjects ) . Urinary nitrite/nitrate , as well as cGMP concentrations , significantly increased after exercise . Nitrite/nitrate excretion rate inversely correlated to neutrophil adhesion . No variations were observed in these parameters in iloprost treated patients . The improvement in claudication and the transient increase in urinary nitrite/nitrate suggest a possible nitric oxide-dependent mechanism for the clinical efficacy of physical exercise . The results from the present and previous observations indicate that , besides pharmacological treatments , a regular aerobic exercise improves peripheral arterial occlusive disease
