| Research Abstract |
This research project addressed the ways in which human heat adaptability changes with aging from the viewpoint of whole body coordination. Our findings suggest that in men and women, age-related decrement in thermoregulatory function may involve the input system, effector system, output system, and central system in that order, and the decrement in sweat gland function in the lower limbs may proceed from the lower legs to thigh and from posterior to anterior areas. Our results suggest that non-thermal heat loss response to combined input and sex differences in heat loss responses in young adults tended to decrease with aging. They also suggest that the enhancement of peripheral sweat function toward summer was delayed with aging, the contribution of the skin blood flow adjustment to orthostatic tolerance during the summer heat is smaller in older people, and older people are more prone to thrombogenesis in the summer. Although we failed to find a strategy to delay aging of input and output systems of the thermoregulatory function, the establishment of an exercise habit is effective for the effector system.
