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
