| Outline of Final Research Achievements |
We investigated changes in regional cerebral blood flow (rCBF) during cycling ergometer which was continued at low intensity. Main findings of this research project are; 1) Distribution of increased rCBF during exercise was differed between the onset and a later phase of exercise. Afferent neural impulse from working muscles in lower limbs and central command would have a role in regulation of rCBF during exercise. 2) rCBF reduced after exercise secession by 16 %, approximately, in several regions such as posterior cingulate gyrus. 3) The similar type of exercise as evaluated in the PET study induced changes in regional oxygennation which were distinct from the tendency of those in rCBF.
