Abstract : This report presents a brief review of thermoregulatory models applicable to persons wearing NBC protective clothing. Two models were compared: the USARIEM Heat Strain Model and the UK Loughborough Model (LUT25). Experimental data were derived from an intermittent work protocol (CANADA) and from The Technical Cooperation Program (TTCP) approved continuous work standard research method (UK and US). Subject volunteers from the U.S. and the U.K. were exposed to the TTCP research protocol (Ta = 350C/50% RH, wind speed, V = 1 m%s%', level treadmill speed 3 to 3.5 mph) in their respective country laboratories. Canadian forces volunteers did an intermittent work protocol (15 min moderate work/l5 min rest at Ta = 400C/30% RH, V 0.4 m.s%%). Time analyses of core temperature response predicted from both models and experimental observations were compared using all respective country's data. Other physiological responses, which are affected during the wearing of protective clothing, are discussed for future modeling consideration in TTCP UTP-6 efforts. PG8, JMD
