Conclusion Although data are limited , there is a strong significant relationship between plantar flexor muscle strength and treadmill walking ability .
Background and Objective Exercise is a widely accepted treatment known to improve walking ability in persons with peripheral arterial disease ( PAD ) ; however , it has not been confirmed as to whether exercise improves fitness and performance-based function and , consequently , performance of activities of daily living ( ADL ) .
This systematic review aims to identify whether any mode of structured exercise improves physical fitness or performance-based tests of function and whether improvement in walking ability is related to an improvement in these outcomes .
Data Sources and Study Selection Eligible studies included r and omized controlled trials ( RCTs ) using an exercise intervention for the treatment of intermittent claudication with fitness ( including the 6-min walk ( 6MW ) , aerobic capacity , shuttle and muscle strength ) tests and performance-based tests of function as the outcomes .
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
