Abstract

Objectives: In participants with peripheral arterial disease (PAD), we determined whether more sedentary behavior and slower outdoor walking speed were associated with faster functional decline and more adverse changes in calf muscle characteristics over time. Background: Modifiable behaviors associated with faster functional decline in lower-extremity PAD are understudied. Methods: Participants were 384 men and women with an ankle brachial index 3, average pace -0.46 g/cm3, casual strolling -1.03 g/cm3, no walking at all -1.43 g/cm3, p trend
