| Research Abstract |
We investigated effects of 4-weeks’ running training on the increases in blood pressure (BP) and catecholamine levels induced by a novel stress (immobilization stress) in spontaneously hypertensive rats (SHR). The rats’ sensitivity to exogenously infused norepinephrine (NE) was investigated too. The present results suggest that the stress-induced activation of the sympathetic nervous system and the sensitivity to NE were each attenuated after 4-weeks’ running training, with a consequent reduction in the BP response to a novel stress.
