| Abstract |
The aim of this study is to confirm whether the experienced in short-term and intermittent half body bath (4 sessions, lower body immersion, 42±0.5oC, 30 min/session, for 7 days) can have an influence on the change of the recruitment of activated sweat gland density (ASGD). Subjects were 10 male university students (23.17±2.58 years old, 173.16±3.28 cm height, and weighing 67.68±5.23 kg) who live in Cheonan, Chungnam having no experienced in an artificial thermal stress. This study obtained the mean ASGD from torso (chest, upper back, lower back, abdomen) and limb (upper arm, forearm, thigh, leg) before and after short-term and intermittent half body bath. As the result, it was found that the experienced in short-term and intermittent half body bath significantly increased the whole body sweat loss volume and mean ASGD (p < 0.001). And ASGD increased rate higher in limb (23.8%) than torso (16.5%). In conclusion, our data support the short-term and intermittent half body bath can have an influence on the recruitment of activated sweat gland density. Therefore, evaporative cooling is further facilitated, thermoregulatory efficiency increased by ASGD. |
