| Research Abstract |
The purpose of the present study is to investigate the relationship between body temperature regulation and neurotransmitters in the hypothalamus during incremental treadmill running in the rat. Thermoregulatory responses are dependent on the intensity of the exercise and that these responses are associated with changes in noradrenaline and dopamine release, but not in serotonin release in the hypothalamus. The inhibition of brain dopamine by dopamine D1 antagonist influenced endurance exercise capacity and body temperature. These new findings suggest that the catecholamine in the hypothalamus play a important role of exercise-induced hyperthermia and fatigue.
