Validity of skin, oral and tympanic temperatures during exercise in the heat: effects of wind and sweat

This experiment investigates the validity of six thermometers with different measuring sensors, operation and site of application, to estimate core temperature (Tc) in comparison to an ingestible thermometric sensor based on quartz crystal technology. Measurements were obtained before, during and af...
