The HBET group did not show improvement in MWD/T compared with the WA group ( SMD 0.30 , 95 % CI -0.45 to 1.05 ; P = 0.43 ; moderate- quality evidence ) .Compared with HBET , SET was more beneficial for PFWD/T but had no effect on quality of life parameters nor on self-reported functional impairment .
Compared with WA , SET was more beneficial for PFWD/T and self-reported functional impairment , as well as for some quality of life parameters ( e.g. , physical functioning , pain , and physical component summary after 12 months ) , and HBET had no effect .
Data show no obvious effects on mortality rates .
Evidence of moderate and high quality shows that SET provides an important benefit for treadmill-measured walking distance ( MWD and PFWD ) compared with HBET and WA , respectively .
Although its clinical relevance has not been definitively demonstrated , this benefit translates to increased MWD of 120 and 210 meters after three months in SET groups .
These increased walking distances are likely to have a positive impact on the lives of patients with IC .
Data provide no clear evidence of a difference between HBET and WA .
Trials show no clear differences in quality of life parameters nor in self-reported functional impairment between SET and HBET .
BACKGROUND Although supervised exercise therapy ( SET ) provides significant symptomatic benefit for patients with intermittent claudication ( IC ) , it remains an underutilized tool .
Widespread implementation of SET is restricted by lack of facilities and funding .
Structured home-based exercise therapy ( HBET ) with an observation component ( e.g. , exercise logbooks , pedometers ) and just walking advice ( WA ) are alternatives to SET .

OBJECTIVES The primary objective was to provide an accurate overview of studies evaluating effects of SET programs , HBET programs , and WA on maximal treadmill walking distance or time ( MWD/T ) for patients with IC .
Secondary objectives were to evaluate effects of SET , HBET , and WA on pain-free treadmill walking distance or time ( PFWD/T ) , quality of life , and self-reported functional impairment .
Effects of walking and strength training on resting and exercise cardiovascular responses in patients with intermittent claudication.
BACKGROUND Exercise training is recommended as the first-line therapy for intermittent claudication patients . However , the effects of exercise therapy on cardiovascular function of these patients have been poorly studied . The aim of this study is to compare the effects of walking and strength training on cardiovascular responses assessed at rest and during exercise in patients with intermittent claudication . PATIENTS AND METHODS Thirty-four patients with stable symptoms of intermittent claudication were r and omized into two groups : strength training ( ST ) consisting of eight exercises , three sets of 10 repetitions , intensity of 11 - 13 on 15- grade Borg scale , 2-min interval between sets ; and walking training ( WT ) consisting of walking on a treadmill , 15 bouts of 2-min , intensity of 11 - 13 on 15- grade Borg scale , with a 2-min interval between bouts . Before and after 12 weeks , blood pressure , heart rate and rate pressure product were measured at rest and during a progressive treadmill test until maximal claudication pain . RESULTS Fifteen patients in each group completed the training program . After the training programs , resting systolic blood pressure ( ST:-6 ± 13 mmHg and WT:-3 ± 18 mmHg , P = .04 ) , heart rate ( ST : -6 ± 10 bpm and WT:-2 ± 9 bpm , P = .03 ) , and rate pressure product ( ST:-1485 ± 1442 mmHg*bpm and WT:- 605 ± 2145 mmHg*bpm , P = .01 ) decreased significantly and similarly in both groups . Submaximal systolic blood pressure ( ST : -14 ± 23 mmHg and WT:-6 ± 23 mmHg , P = .02 ) , and rate pressure product ( ST:-1579 ± 3444 mmHg*bpm and WT : -1264 ± 3005 mmHg*bpm , P = .04 ) decreased significantly and similarly in both groups . There were no changes in submaximal heart rate after ST and WT . Maximal systolic blood pressure , heart rate , and rate pressure product did not change in either group , although maximal exercise time increased similarly in the ST and WT groups ( + 31 ± 19 % , and + 31 ± 32 % , respectively , P < .01 ) . CONCLUSIONS Strength and walking trainings promoted similar increases in walking capacity and decreases in resting and submaximal exercise cardiovascular load
