AbstractObjectivesTo assess if exercise training improves the symptoms of intermittent claudication by improvement in cardiopulmonary fitness.MethodsClaudication distance (CD), maximum walking distance (MWD), calf endurance (repetitive heel raises), cardiovascular fitness (VO2 peak), and ankle-brachial pressure index (ABPI) were measured in 16 subjects with intermittent claudication before, and following an 8-week treadmill training programme.ResultsTraining resulted in a median increase in CD of 65.5m (p<0.01), MWD of 339.5m (p<0.001) and HR of 19 (p<0.03). Notably, improvements in MWD correlated with those in HR (p=0.001; R=0.75). There was no training-associated change in VO2 peak (median increase of only 0.35ml/kg/min; p=0.60) or ABPI (...
