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 .
Influence of upper- and lower-limb exercise training on cardiovascular function and walking distances in patients with intermittent claudication.
PURPOSE The effects of upper-limb ( arm cranking ) and lower-limb ( leg cranking ) exercise training on walking distances in patients with intermittent claudication was assessed . METHODS Sixty-seven patients ( 33 to 82 years old ) with moderate to severe intermittent claudication were recruited , and the maximum power generated during incremental upper- and lower-limb ergometry tests was determined , as were pain-free and maximum walking distances ( by using a shuttle walk test ) . Patients were r and omly assigned to an upper-limb training group ( n = 26 ) or a lower-limb training group ( n = 26 ) . An additional  untrained group ( n = 15 ) was recruited on an ad hoc basis in parallel with the main trial by using identical inclusion criteria . This group was subsequently shown to possess a similar demographic distribution to the two exercise groups . Supervised training sessions were held twice weekly for 6 weeks . RESULTS Both training programs significantly improved the maximum power generated during the incremental upper- and lower-limb ergometry tests ( P < . 001 ) , which may reflect an increase in central cardiovascular function that was independent of the training mode . More importantly , pain-free and maximum walking distances also improved in both training groups ( P < .001 ) . The improvements in the training groups were similar ; there were no changes in the untrained control group . These findings suggest that the symptomatic improvement after upper-limb exercise training may result , in part , from systemic cardiovascular effects rather than localized metabolic or hemodynamic changes . CONCLUSION Carefully prescribed upper-limb exercise training can evoke a rapid symptomatic improvement in patients with claudication , while avoiding the physical discomfort experienced when performing lower-limb weight-bearing exercise
