| Outline of Final Research Achievements |
The goal of this research is to confirm the efficacy of ankle exercises for cerebral hemodynamics.
In the first study, each participant repeated ankle plantar flexion and dorsiflexion movements for 1 minute. Heart rate (HR), blood pressure (BP), and cerebral OxyHb levels were recorded. Two types of exercises were used, active movement and passive movement. Both active and passive ankle exercises increased cerebral blood oxygenation.
Three conditions (active/passive, and control) were examined in the second study. After the ankle exercise was finished, the participants changed their posture from supine to sitting. Active ankle exercise showed significantly higher OxyHb than the others(passive and control) during and after postural change. On the other hand, no significant difference was detected between passive exercise and the control condition. Active ankle exercise which was performed before postural change has the possibility of attenuating the initial changes in cerebral OxyHb.
