Transcranial Doppler ultrasound-determined middle (MCA) and anterior (ACA) cerebral
artery mean flow velocities (Vmean) and pulsatility indexes (PI) were measured during “no …

Dynamic exercise enhances regional cerebral artery mean flow velocity. J. Appl. Physiol. 78
(1): 12–16, 1995.--Anterior (ACA) and middle (MCA) cerebral artery mean flow velocities …

Factors controlling cerebral blood flow (CBF) during exercise are complex and incompletely
known. Different techniques have shown partly contradictory results of changes in regional …

Cerebral blood flow has been reported to increase during dynamic exercise, but whether
this occurs in proportion to the intensity remains unsettled. We measured middle cerebral …

Results obtained by the 133Xe clearance method with external detectors and by transcranial
Doppler sonography (TCD) suggest that dynamic exercise causes an increase of global …

Changes in middle cerebral artery flow velocity (Vmean), measured by transcranial Doppler
ultrasound, were used to determine whether increases in mean arterial pressure (MAP) or …

This study examined the consistency between three indexes of cerebral blood flow (CBF)
obtained by using transcranial Doppler ultrasound in eight human volunteers. Each subject …

Cerebral blood flow (CBF) in humans was measured at rest and during dynamic exercise on
a cycle ergometer corresponding to 56%(range 27–85) of maximal O2 uptake (VO2max) …

Exercise challenges cerebral autoregulation (CA) by a large increase in pulse pressure (PP)
that may make systolic pressure exceed what is normally considered the upper range of CA …

The effect on the middle cerebral artery blood flow velocity (V MCA) of moderate and hard
physical exercise on an ergometer cycle was examined in 10 healthy volunteers using …
