May warrant caution when interpreting cerebral velocity amid cardiac output shifts; leaves open clinical relevance in patients or disease.
Do changes in cardiac output affect middle cerebral artery mean blood velocity at rest and during exercise in healthy men?
Changes in central blood volume and cardiac output linearly influence middle cerebral artery mean blood velocity independently of cerebral autoregulation, with the relationship modified by exercise.
Ogoh et al. (2005) studied this question.
