Abstract (EN):
The present article presents a project that studies the decrease of physical and mental performance of soldiers submitted to extreme dry hot conditions and the effectiveness of acclimation procedures to prevent the usual heat illnesses of the subjects in missions. A series of tests in controlled environment at 22°C-40% RH and at 40°C-30% RH was performed by 6 militaries. The principal psychophysical parameters presented in this article are Borg Rating Perceived Exertion (RPE) scale, lactate, core temperature and dehydration. Physical exertion raise rapidly core temperature in thermoneutral and in hot dry conditions. Oxygen uptake results show that in hot, energy consumption is higher that leads to faster exhausted state. Presented data are in accordance to the expected results obtained in literature what lead to the justification of the importance of additional training procedures, such as acclimation, that intend to prevent heat illnesses and improve interventional capability in operational field. © 2016 Taylor & Francis Group, London.
