The purpose of this study is to examine differences in body cooling according to the parts immersed in high-concentration artificial carbonic acid water.
The subjects’ core (tympanic) temperature was increased by a pedal ergometer. They then immersed their hands or hands and forearms in stirred 25°C carbonic acid water. The decrease in tympanic temperature was observed.
There was no significant difference in the decrease in tympanic temperature between the two conditions.
The results suggest that immersing the hands in carbonic acid water might reduce core temperature elevated by exercise heat production/environmental heat stress to the same extent as immersing the forearms.
