Abstract

Objectives: To test the hypothesis that volume or intensity of daily ambulatory activity would associate with greater large artery compliance in healthy untrained adults. Design: Forty-five recreationally active young adults (22 ± 3 yr, 51% women) wore an accelerometer for 5.3 ± 1.3 days for determination of average daily steps (volume) and 30-min peak stepping cadence (intensity; average steps per min for the 30 highest min in a day). Arterial compliance of the common carotid artery, superficial femoral artery (SFA), and popliteal artery was estimated using Doppler ultrasound. Data were analyzed using Pearson correlations, stepwise multiple regression, semipartial correlations, and ANCOVA. Results: Average daily steps and peak stepping cadence was 8957 ± 3422 steps per day and 97 ± 24 steps per min, respectively. Weight was the main independent predictor of daily steps (r2=0.13, p=0.01) and peak stepping cadence (r2=0.17, p<0.01). After adjusting ambulatory activity for weigh
