잠수복 착용 피검자에서 침수시 잠수장갑 및 버선 착용에 따른 체온조절기능의 변화 = Changes in Thermoregulatory Response by wearing Gloves and Boots in Wet-Suited Subjects immersed in Cold Water

다국어 초록 (Multilingual Abstract)

In 5 wet-suited subjects, changes in body temperature, heat exchanges and thermal insulations were studied at rest and during exercise in water of 13℃. The subjects wore neoprene gloves and boots in one series and exposed their hands and feet to water in the other series of experiments.
In the subjects resting in water, the gloves and boots did not affect the level of rectal temperature but increased the mean skin temperature slightly, reducing the core-to-skin temperature gradient. However, the total thermal insulation of the subject was reduced significantly and consequently the rate of skin heat loss was increased by wearing gloves and boots. The metabolic response of the subject appeared to be significantly augmented by wearing gloves and boots.
In exercising subjects the level of body temperature and the thermo-regulatory variables were not apparently changed by wearing gloves and boots.
These results indicated that in wet-suited subjects resting in cold water, exposure of hands and feet increases peripheral insulation and consequently effectively reduces heat loss to water. Such an effect of peripheral cooling is lost during exercise by hypermia to skeletal muscles in the limbs.
