| Outline of Final Research Achievements |
Blood-volume expansion after heat acclimation improves thermoregulatory responses via baroreflexes. We have been reported that skin sympathetic nerve activity involves a component of synchronized cardiac cycle (UAssna), it increased with an increase in body temperature and the increase was suppressed by head-up tilt as well as hypovolemia, suggesting that the component would be associated with an control of active cutaneous vasodilator through baroreflexes. Our study has shown that the increase in the component was enhanced after 5-day endurance training with an increase in blood volume and enhanced cutanoues vasodilation responses at a given increase in body temperature. The component would be related with improvement of coutaneous vasodilation responses through barorelexes after heat acclimation.
