BACKGROUND Exercise programmes are a relatively inexpensive , low-risk option compared with other , more invasive therapies for treatment of leg pain on walking ( intermittent claudication ( IC ) ) .

OBJECTIVES Our goal was to determine whether an exercise programme was effective in alleviating symptoms and increasing walking treadmill distances and walking times in people with intermittent claudication .
Secondary objectives were to determine whether exercise was effective in preventing deterioration of underlying disease , reducing cardiovascular events , and improving quality of life .
Impact of a supervised strength training or walking training over a subsequent unsupervised therapy period on walking capacity in patients with claudication.
Previous studies have demonstrated that supervised strength training ( ST ) or walking training ( WT ) improve walking capacity in patients with claudication . However , it remains unknown whether these improvements would be sustained over a subsequent unsupervised period . This article reports the findings of a study to analyze whether the improvements in walking capacity , achieved with a supervised ST or WT , would be sustained over a subsequent unsupervised therapy period in patients with claudication . Patients were initially r and omized to supervised exercise consisting of ST  ( n = 15 ) or  WT  ( n = 15 ) for 12 weeks . After this period , 12 patients in each group consented to be followed for an additional 12 weeks of unsupervised therapy .  Initial claudication distance ( ICD ) and total walking distance ( TWD ) were measured at baseline , after the supervised period ( Week 12 ) and after the unsupervised period ( Week 24 ) . In comparison with baseline values , both groups similarly increased ICD and TWD at Week 12 . From Week 12 to Week 24 , both groups similarly decreased ICD ( ST : -55 ± 110 m and WT : -82 ± 142 m , P = .04 ) and TWD ( ST : -68 ± 186 m and WT : -128 ± 112 m , P < .01 ) . However , in both groups , ICD ( ST : + 126 ± 149 m and WT : + 50 ± 167 m , P = .01 ) and TWD ( ST : + 104 ± 162 m and WT : + 45 ± 139 m , P = .01 ) at Week 24 remained greater than baseline values . The conclusion is that supervised ST or WT followed by an unsupervised therapy period similarly decreased walking capacity in patients with claudication . However , after the unsupervised period , walking capacity remained at a higher level than before the onset of the supervised exercise-training period
