Treadmill exercise and resistance training in patients with peripheral arterial disease with and without intermittent claudication: a randomized controlled trial.
CONTEXT Neither supervised treadmill exercise nor strength training for patients with peripheral arterial disease ( PAD ) without intermittent claudication have been established as beneficial . OBJECTIVE To determine whether supervised treadmill exercise or lower extremity resistance training improve functional performance of patients with PAD with or without claudication . DESIGN , SETTING , AND PARTICIPANTS R and omized controlled clinical trial performed at an urban academic medical center between April 1 , 2004 , and August 8 , 2008 , involving 156 patients with PAD who were r and omly assigned to supervised treadmill exercise , to lower extremity resistance training , or to a control group .  MAIN OUTCOME MEASURES Six-minute walk performance and the short physical performance battery . Secondary outcomes were brachial artery flow-mediated dilation , treadmill walking performance , the Walking Impairment Question naire , and the 36-Item Short Form Health Survey physical functioning ( SF-36 PF ) score . RESULTS For the 6-minute walk , those in the supervised treadmill exercise group increased their distance walked by 35.9 m ( 95 % confidence interval [ CI ] , 15.3 - 56.5 m ; P < .001 ) compared with the control group , whereas those in the resistance training group increased their distance walked by 12.4 m ( 95 % CI , -8.42 to 33.3 m ; P = .24 ) compared with the control group . Neither exercise group improved its short physical performance battery scores . For brachial artery flow-mediated dilation , those in the treadmill group had a mean improvement of 1.53 % ( 95 % CI , 0.35%-2.70 % ; P = .02 ) compared with the control group . The treadmill group had greater increases in maximal treadmill walking time ( 3.44 minutes ; 95 % CI , 2.05 - 4.84 minutes ; P < .001 ) ; walking impairment distance score ( 10.7 ; 95 % CI , 1.56 - 19.9 ; P = .02 ) ; and SF-36 PF score ( 7.5 ; 95 % CI , 0.00 - 15.0 ; P = .02 ) than the control group . The resistance training group had greater increases in maximal treadmill walking time ( 1.90 minutes ; 95 % CI , 0.49 - 3.31 minutes ; P = .009 ) ; walking impairment scores for distance ( 6.92 ; 95 % CI , 1.07 - 12.8 ; P = .02 ) and stair climbing ( 10.4 ; 95 % CI , 0.00 - 20.8 ; P = .03 ) ; and SF-36 PF score ( 7.5 ; 95 % CI , 0.0 - 15.0 ; P = .04 ) than the control group . CONCLUSIONS Supervised treadmill training improved 6-minute walk performance , treadmill walking performance , brachial artery flow-mediated dilation , and quality of life but did not improve the short physical performance battery scores of PAD participants with and without intermittent claudication .  Lower extremity resistance training improved functional performance measured by treadmill walking , quality of life , and stair climbing ability .
