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 .
A randomised controlled trial of supervised exercise regimens and their impact on walking performance, skeletal muscle mass and calpain activity in patients with intermittent claudication.
OBJECTIVES Supervised exercise training ( SET ) is recommended for patients with intermittent claudication ( IC ) . The optimal exercise programme has not been identified , and the potential adverse effects of exercise on these patients warrant consideration . Calpain proteases have been linked with tissue atrophy following ischaemia-reperfusion injury . High calpain activity may therefore cause muscle wasting in claudicants undergoing SET , and skeletal muscle mass ( SMM ) is integral to healthy ageing . This study assesses the impact of ( 1 ) treadmill-based SET alone ; and ( 2 ) treadmill-based SET combined with resistance training on pain-free walking distance ( PFWD ) , SMM , and calpain activity . METHODS Thirty-five patients with IC were r and omised to 12 weeks of treadmill only SET ( group A ) , or combined treadmill and lower-limb resistance SET ( group B ) . PFWD via a 6-minute walking test , SMM via dual energy X-ray absorptiometry , and calpain activity via biopsies of gastrocnemius muscles were analysed . RESULTS Intention-to-treat analyses revealed PFWD improved within group A ( 160 m to 204 m , p = .03 ) , but not group B ( 181 m to 188 m , p = .82 ) . There was no between group difference ( p = .42 ) . Calpain activity increased within group A ( 1.62 × 10(5 ) fluorescent units [ FU ] to 2.21 × 10(5 ) FU , p = .05 ) , but not group B. There was no between group difference ( p = .09 ) . SMM decreased within group A ( -250 g , p = .11 ) and increased in group B ( 210 g , p = .38 ) ( p = .10 between groups ) . Similar trends were evident for per protocol analyses , but , additionally , change in SMM was significantly different between groups ( p = .04 ) . CONCLUSIONS Neither exercise regimen was superior in terms of walking performance . Further work is required to investigate the impact of the calpain system on SMM in claudicants undertaking SET
