Data showed improvements secondary to exercise in ' physical function ' and ' general health ' .
The other domains - ' role physical ' , ' bodily pain ' , ' vitality ' , ' social ' , ' role emotional ' , and ' mental health ' - did not show improvement at six months .
Although results showed significant heterogeneity between trials , population s and outcomes were comparable overall , with findings relevant to the claudicant population .
High- quality evidence shows that exercise programmes provided important benefit compared with placebo or usual care in improving both pain-free and maximum walking distance in people with leg pain from IC who were considered to be fit for exercise intervention .
Exercise did not improve ABI , and we found no evidence of an effect of exercise on amputation or mortality .

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 .
Effective training for patients with intermittent claudication
Objective . Current guidelines for treatment of intermittent claudication ( IC ) do not include a specific recommendation for the intensity of exercise therapy . Thus , the purpose of this study was to determine the relative effectiveness of high versus low intensity exercise for patients with IC , and further to study the effect of such training on blood flow to the legs during exercise . Design . The effect of eight weeks of supervised endurance training was examined in 16 patients with IC . The patients were r and omly assigned to training at intensities corresponding to either 60 % or 80 % of their peak oxygen consumption ( VO2peak ) , respectively . Results . VO2peak and time to exhaustion increased significantly ( 9 % and 16 % , respectively ) more in the high intensity group ( p<0.05 ) . Blood flow to the legs did not change after training in any of the groups . Conclusion . High intensity training gave larger improvements in VO2peak and time to exhaustion than low intensity training . As blood flow did not change after the exercise program , it is likely that the observed different increase of VO2peak was due to changed mitochondrial oxidative capacity and /or skeletal muscle diffusive capacity
