| Research Abstract |
(1) This study demonstrated that pedaling exercise (PE) induces increased activity in the ventral prefrontal cortex (PFC) region, which may be responsible for the accompanying feeling of decreased negative mood with increased vigor-activity. (2) PE induces significant increases in the powers of alpha bands in EEG. These results suggest that such EEG changes are linked with the increased blood 5-HT levels, or an augmentation of the 5-HT system in the brain stem. (3) The activation of the ventral PFC during PE may also be responsible for the augmentation of the 5-HT system. (4) Nociceptive withdrawal reflex was decreased during PE, which indicates that PE suppress nociceptive response via the 5-HT descending inhibitory pathway.
