Secondary objectives were to determine whether exercise was effective in preventing deterioration of underlying disease , reducing cardiovascular events , and improving quality of life .
Increasing exercise tolerance of persons limited by claudication pain using polestriding.
OBJECTIVE The efficacy of polestriding exercise ( walking with modified ski poles with a movement pattern similar to cross-country skiing ) to increase exercise tolerance of persons with intermittent claudication pain caused by peripheral arterial disease was tested in this 24-week prospect i ve r and omized clinical trial . METHODS The study was conducted in a Department of Veterans Affairs Hospital with 52 individuals who gave written informed consent and were r and omized into either a polestriding exercise ( n = 27 ; age , 65.5 + /- 7.0 years ; ankle brachial index , 0.64 + /- 0.25 ) or nonexercise control ( n = 25 ; age , 68.6 + /- 8.9 years ; ankle brachial index , 0.69 + /- 0.14 ) group ( P > .05 for all comparisons ) . The polestriding exercise program consisted of supervised training three times per week for 4 weeks , two times per week for 8 weeks , one time per week for 4 weeks , biweekly for 4 weeks and unsupervised training for 4 weeks . Starting in week 5 , subjects took their poles home with instructions to repeat the most recent supervised training walk at an appropriate and convenient location near their residence . This was referred to as unsupervised but directed exercise . Subjects were provided with a personal log book for documenting unsupervised exercise sessions . With both supervised and unsupervised exercise , subjects were expected to complete a total of four 30-minute to 45-minute polestriding exercise sessions per week . The main outcome measures were exercise duration on symptom-limited incremental treadmill test , Walking Impairment Question naire , rating of perceived leg pain at baseline , 4 , 8 , 12 , 16 , and 24 weeks , and constant work-rate treadmill exercise tests at baseline and at 4 , 12 , and 24 weeks . RESULTS Polestriding significantly ( P < .001 ) improved exercise tolerance on the constant work-rate and incremental treadmill tests . Ratings of perceived claudication pain were significantly less after the polestriding training program .  Subject perceived distance and walking speed scores on the Walking Impairment Question naire improved in the polestriding trained group only ( P < .001 and .022 , respectively ) . CONCLUSION This r and omized clinical trial provides empirical evidence that 24 weeks of polestriding training significantly improves quantitative and qualitative measures of the exercise tolerance of persons limited by intermittent claudication pain
