| Outline of Final Research Achievements |
The present study aimed to investigate the factors that alter cerebral blood flow during and after 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, and HHb were measured by near-infrared spectroscopy during the exercise. Physiological parameters were simultaneously measured during and after the exercise.
O2Hb levels increased significantly between the pre-exercise rest period and the last 5 min of the exercise session for each region of interest. O2Hb levels did not return to pre-exercise values during the 15-min post-exercise rest period. O2Hb levels during the 15 min of the post-exercise rest period were significantly higher than pre-exercise values in some regions. These changes have no relation to physiological parameters.
