Abstract

We compared the changes in ambulatory outcomes between men and women with symptomatic peripheral arterial disease (PAD) following completion of a supervised, on-site, treadmill exercise program, and we determined whether exercise training variables and baseline clinical characteristics were predictive of changes in ambulatory outcomes in men and women. Twenty-three men and 25 women completed the supervised exercise program, consisting of intermittent walking to mild-to-moderate claudication pain for three months. Men and women significantly increased claudication onset time (COT) (p<0.001 and p<0.01, resp.) and peak walking time (PWT) (p<0.001 for each group). However, change in PWT was less in women (54%) than in men (77%) (p<0.05). Neither group significantly changed 6-minute walk distance (6MWD). In women, baseline COT was the only predictor for the change in COT (p=0.007) and the change in PWT (p=0.094). In men, baseline COT (p<0.01) and obesity (p<0.10) were predictors for the change in COT, and obesity was the only predictor for the change in PWT (p=0.002). Following a supervised, on-site, treadmill exercise program, women had less improvement in PWT than men, and neither men nor women improved submaximal, overground 6MWD. Furthermore, obese men and patients with lower baseline COT were least responsive to supervised exercise.
