Age-related changes in the values of lower limb peripheral blood flow

Abstract

The rate of lower limb magistral and capillary blood flow has been studied in 580 female and male subjects at the age from 6 to 75 years using the techniques of ultrasound and laser Doppler flowmetry. It has been demonstrated that as far as age increases regional and systemic arterial pressure (AP) becomes higher, the rate of linear blood flow along the femoral artery decreases and it increases along the leg and foot arteries. At the age above 50 years the functional reserves of vascular bed adaptation, initially higher in women, begin decreasing.
