| Outline of Final Research Achievements |
The present study aimed to investigate the factors that alter cerebral blood flow during a pedaling exercise using a cycle ergometer. Healthy volunteers participated in this study. They performed a cycle ergometer exercise at low, moderate, and high intensity. Subjects’ O2Hb level, an indicator of cerebral blood flow, was measured by near-infrared spectroscopy during the exercise. Regions of interest were the presupplementary motor area, supplementary motor area, and sensorimotor cortex. Physiological parameters were simultaneously measured. Decreased O2Hb levels were observed only during the high-intensity exercise, with the greatest decrease observed in the sensorimotor cortex. No relationship was found between decreased O2Hb levels and changes in physiological parameters. Alterations in O2Hb levels during high-intensity exercise might result in changes in the brain.
