Randomized Controlled Trial
Relative importance of step count, intensity, and duration on physical activity's impact on vascular structure and function in previously sedentary older adults.
Age-related endothelial dysfunction and vascular stiffening are associated with increased cardiovascular (CV) risk. Many groups have encouraged goals of ≥10 000 steps/day or ≥30 min/day of moderate intensity physical activity (MPA) to reduce age-related CV risk. The impact of MPA on the vasculature of older adults remains unclear. ⋯ Clinicaltrials.gov. UNIQUE IDENTIFIER: NCT-01212978.
