Research Abstract |
Effects of cooling mask were compared in two conditions on thermoregulatory responses in participants wearing protective clothing for pesticide. In 1999 (Experiment I), we compared special designed cooling mask (B) with normal (no cooling) mask (A). In 2000 (Experiment II), we compared the cooling mask with head cooling (D) and without head cooling (C). In both experiments six female adults served as subjects, in a climate chamber controlled at 28℃, 60% RH. They were exercising on a bicycle ergometer (Vo_<2mas> 50%) wearing the mask and protective clothing. The main results are summarized as follows : (1) rectal temperature was significantly inhibited in B than in A in Experiment I, (2) microclimate temperature on the chest was significantly lower in B than in A in Experiment I, (3) external aditory meatus temperature was significantly inhibited in D than in C in Experiment II, (4) microclimate temperature inside mask was significantly lower in D than in C, (5) sweat rate seemed to be inhibited in D. Thus, it was concluded that our newly designed cooling mask and head cooling could reduce thermal strain with improved thermal sensation in warm environment.
