The heat strain of wearing the current generation of nuclear, biological and chemical (NBC) protective ensembles is well documented for many nations and the concerns for Canadian military personnel are no different than those of our Allies. During the past 10 years, we have made attempts to not only define this heat strain for the Canadian Forces NBC clothing over a range of metabolic rates and different environmental conditions but also to examine the influence that factors such as aerobic fitness, hydration, heat acclimation, menstrual cycle, body composition and circadian rhythm have on work tolerance to exercising in hot environments while wearing the NBC clothing. The purpose of this paper is to provide an overview of this work.
