Abstract
|
|
|
Thermoregulation of wet suit divers were studied during breath-hold diving in the sea and during exercise in temperature regulated water bath in 1, 2 and 3 ATA.
1 ) During breath-hold diving, heat loss in Korean women wet suit divers was more than 96% compensated by heat production, thus rectal temperature was decreased by only 0.41C in summer (22.50 water) and 0.6t in winter (101C winter) during 2hr diving work.
2) Duri ng-immersion in cold water (14--19.50, total thermal insulation of the wet suit diver decreased as an exponential function of the exercise intensity, thus the steady state rectal temperature was not different whether the subject exercised or not.
3) The apparent insulation afforded by the wet suit decreased as a function of pressure, and at the same pressure it decreased as a function of exercise intensity.
4 ) Practical consequence of these results will be discussed.
