Impact of body position on central and peripheral hemodynamic contributions to movement-induced hyperemia: implications for rehabilitative medicine
This study used alterations in body position to identify differences in hemodynamic
responses to passive exercise. Central and peripheral hemodynamics were noninvasively
measured during 2 min of passive knee extension in 14 subjects, whereas perfusion
pressure (PP) was directly measured in a subset of 6 subjects. Movement-induced increases
in leg blood flow (LBF) and leg vascular conductance (LVC) were more than twofold greater
in the upright compared with supine positions (LBF, supine: 462±6, and upright: 1,084±159 …
