| Research Abstract |
Signals from higher brain centers (central command), which are thought to be related to the preparatory responses before the onset of voluntary contraction and the 'effort sense' of the exercising muscles, are important for the cardiovascular control during exercise. The present study found that the central command probably caused an instantaneous increase in the cerebral blood flow (CBF) in 'the vertebral root' before the onset of voluntary exercise and also increased the CBF in both 'the vertebral root' and 'the internal carotid root' during sustained exercise.
