Abstract : Eighteen young adults were subjected to daily treatments of 30 minutes of either light negative and/or moderate to heavy positive work on a laddermill at 22C followed by 30 minutes of either 3.5 mph walk at 50C/25C db/wb room temperatures or sitting under these ambient conditions with additional radiant heat, for four days. Their state of acclimatization was tested by exposure, up to 120 minutes, to 50C/25C db/wb using the following specific criteria: tolerance time (t) to 3.5 mph walk; evelation of heart rate (HR) and rectal temperature (Tre); fall in mean skin temperature (Tsk); and change of sweating. A method of stints of exercise at room temperature followed by short heat exposures might prove an efficient method of acclimatization for large groups when time and hot spaces are wanting.
