Conditions
Outcome Measures
Primary Outcomes (1)
Change in endothelium-dependent dilation
Brachial artery endothelium-dependent flow-mediated dilation to reactive hyperemia will be measured using high resolution ultrasonography. To determine flow-mediated dilation, brachial artery diameter and blood velocity will be measured before and after occluding the forearm for 5 minutes by inflating a cuff to 250 mmHg.
Baseline, 15 minutes after exercise and 1 hour after exercise
Secondary Outcomes (2)
Change in endothelium-independent dilation
Baseline, 15 minutes after exercise
Change in arterial stiffness and wave reflection
Baseline, 15 minutes after exercise and 1 hour after exercise
Study Arms (1)
Slow-paced walking
EXPERIMENTALSubjects will complete 47 minutes of walking at slow pace.
Interventions
Subjects will walk on a treadmill at a slow pace for 47 minutes
