Abstract
Oesophageal, rectal and left middle finger tip temperatures were measured in response to three exercise-recovery cycles which produced rectal temperature fluctuations between 38.5C and 38.3C while wearing light, moderate and heavy insulation clothing. It was found that temperatures rose more quickly and fell more slowly when wearing more clothing. Oesophageal temperature changes paralleled rectal temperature changes however, they rose to a higher level and fell to a lower level. Finger temperature, in contrast, fell as rectal temperature rose and rose as rectal temperature fell. In all cases, the insulation induced changes of response of all temperature profiles are neither distinctive nor stable enough to depend on the use of the protocol of this study to identify the effects of different insulating layers on the onset of heat stress.
