Study of Thermoregulation in Exercise Heat Stroke in the Military Environment

This is an incremental exercise under maximal pedaling on an Excalibur® type bike with electromagnetic brake over 36 minutes during which gas exchanges are continuously measured through a face mask (Cosmed®).

"The test consists of a walk on a treadmill in shorts, bare chest or bra for women, at 5 km/h and 2% slope in an environment at 40°C, 40% relative humidity, without convection.~During the test, rectal temperature, heart rate and skin temperature will be monitored continuously.~The blood pressure will be measured manually every 30 minutes during the test."

"This test consists in applying a thermal flux generated by an infrared light source on a beam of 1 cm diameter on 2 areas of the dominant lower limb (glabrous face of the forearm and thenar eminence).~Participants will be instructed to remove their limb as soon as the sensation of heat begins to become uncomfortable.~The time between the beginning of the stimulus and the moment of withdrawal will be recorded."
