Abstract

The aim of this study was to determine if stepping cadence when controlling for total steps has a differential impact on regional vascular function. Sixteen young adults (21 ± 2 yrs) performed fast (125 steps per min) and slow (80 steps per min) walking for a total of 3000 steps on separate days. Doppler ultrasound was used to measure compliance, blood flow, and shear rate of the common carotid artery and superficial femoral artery before walking along with 30 and 60 min after walking. Carotid compliance was significantly (p<0.05) elevated 60 min after fast (17.1 ± 25.9%) and slow (24.1 ± 27.3%) walking. Both fast and slow walking failed to increase femoral compliance, despite significant (p<0.05) dilation in the femoral artery that was observed at 30 (4.2 ± 3.9%) and 60 min (3.9 ± 5.4%) after fast walking. Consistent with this latter finding, femoral blood flow (45.8 ± 41.4%) and shear rate (29.0 ± 34.2%) were significantly (p<0.05) increased at 30 min after fast but not slow wal
