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 .

Comparison of the effect of upper body-ergometry aerobic training vs treadmill training on central cardiorespiratory improvement and walking distance in patients with claudication.
BACKGROUND Supervised treadmill-walking exercise programs have been proven to be a highly effective in improving walking distance in peripheral arterial disease ( PAD ) patients with lifestyle-limiting claudication . Limited information is available on the contributions of central cardiorespiratory functions for improving these patients ' walking capacity with exercise training . METHODS This study r and omized 28 participants ( 21 men ; age , 65.6 years ; 92.7 % smoking history , 36.6 % with diabetes ) with lifestyle-limiting PAD-related claudication to 3 hours/week of supervised exercise training for 12 weeks  , using arm-ergometry ( n = 10 ) or treadmill-walking ( n = 10 ) vs a usual-care control group ( n = 8) . Cardiorespiratory function measurements were assessed before and after training at a submaximal workload and at the onset of claudication ( pain-free walking distance [ PFWD ] ) and at maximal walking distance [ ( MWD ] ) . Changes in these functions from baseline were analyzed among the groups with analysis of covariance . Associations between variables were determined by Pearson 's partial correlations . RESULTS The mean baseline demographic , medical , and exercise variables were similar among the groups . There were similar significant differences in the submaximal double product ( heart rate × systolic blood pressure ) and at MWD , ventilatory threshold , ventilatory oxygen uptake ( VO(2 ) ) at onset of claudication , and VO(2 ) peak in response to training in both exercise groups vs the control group . Statistically significant , moderate correlations ( r = 0.60 - 0.68 ) were found between changes in all cardiorespiratory variables and changes in PFWD or MWD . CONCLUSION Improvements in cardiorespiratory function after arm-ergometry or treadmill-training were significantly associated with improvements in both PFWD and MWD , providing supporting evidence of systemic contributions to exercise training-related improvements in walking capacity seen in patients with claudication
