| Outline of Final Research Achievements |
The preoptic area and anterior hypothalamus (PO/AH) is considered to be the primary locus for thermoregulatory system. In addition, serotonin (5-HT), dopamine (DA) and norepinephrine (NE) are very important monoaminergic neurotransmitter and its system has been involved in the regulation of thermoregulation. In this study, we investigated in the effects of voluntary exercise on brain monoaminergic neurotransmitters and thermoregulation in rats. Results showed that the heart rate in the voluntary exercise group were lower level compared with control group. Furthermore, core body temperature in the exercise group also showed clear circadian rhythm during the day compared with control group. The levels of NE and DA in the PO/AH in voluntary exercise group were higher than control group significantly. These results indicate that voluntary exercise may affect on the health and condition in the brain neurotransmitters.
