Why the study?
Does graded exercise affect different indexes of cerebral blood flow measured by transcranial Doppler ultrasound consistently in human volunteers?
Does graded exercise affect different indexes of cerebral blood flow measured by transcranial Doppler ultrasound consistently in human volunteers?
Increases in cerebral blood flow during exercise measured by transcranial Doppler ultrasound may be artifactual due to changes in the arterial pressure waveform, as different flow indexes yield inconsistent results.

Inconsistent TCD indexes during low-intensity exercise suggest possible artifacts; leaves open true CBF changes and requires validated measures.
Poulin et al. (1999) studied this question.
