Table 1 shows the physical characteristics of the subjects. All the groups were similar in all the investigated characteristics. None of 40 soldiers showed any symptom of heat
stroke or severe heat exhaustion during or after the EHST.
No results of any medical exams showed any sign of serious
dysfunction. All the soldiers in the group C completed the
EHST. However, only one soldier in the group U successfully completed the EHST, in the rest cases tests were terminated between 45 and 70 minutes, mostly due to reaching the
ethical barrier for Tty 39.5ºC, or intolerable subjective discomfort. In the acclimatized groups, most of the soldiers
managed to finish the test (3 soldiers in the group P and 1 in
the group A terminated the test between 60 and 80 minutes,
reaching the Tty barrier). Even so, their subjective sensation
of discomfort was tolerable, and they were willing to continue the test.
