A Study on the Physiological Responses and the Microclimate in Girdle

Girdle 착용이 인체생리반응과 의복기후에 미치는 영향

The purpose of this study was to confirm the effects of girdle on the physiological responses and the microclimate in summer. The measuring points were rectal temperature, skin temperature, pulse rate and sweat volume as physiological responses and the inside clothing temperature, relative humidity as microclimate when the subjects wore girdle (girdle A; polyurethan+nylon, girdle B; polyurethan+cotton) for the period of rest and exercise in climate chamber. The enviromental conditions were at $25^{\circ}C$ ($65{\pm}5\%$ RH) and $30^{\circ}C$ ($75{\pm}5\%$ RR). The results were as followings. 1. Mean skin temperature increased in girdle during the exercise at $30^{\circ}C$. 2. The pulse rate decreased in girdle during the rest at $25^{\circ}C$. In the case of girdle A, it was remarkably decreased. Rectal temperature increased in girdle A and B during the exercise at $25^{\circ}C$. But the kinds of girdle didn't affect the pulse rate and rectal temperature. 3. The total sweat volume in girdle was larger than in control. 4. The difference between skin temperature and inside clothing temperature of abdomen had a tendency to increase at all experiment condition. 5. The relative humidity of inside ($RH_1$) and outside ($RH_2$) of girdle increased in girdle during the rest at $25^{\circ}C$ and $30^{\circ}C$. And the relative humidity of wearing girdle B was hig-her than girdle A during the rest at $25^{\circ}C$ and $30^{\circ}C$. The $RH_1$ after stepping at $30^{\circ}C$ was the highest in girdle A and the lowest in control. From this point of view, we concluded that physiological responses and the microclimate were affected by wearing girdle. And mean skin temperature and relative humidity of inside clothing were affected by the materials of girdle.
