Abstract
A new vapour protective clothing ensemble is under development at the Defence Research Establishment Ottawa. This new clothing is thinner and more close-fitting to the body than the present NBC protective ensemble. The purpose of the present study, therefore, was to examine the influence of this new vapour protective clothing on physical work performance in a hot environment. Eleven males were allocated to exercise at either a light intermittent (L) (15 min exercise followed by 15 min rest, N = 6), or heavy continuous (H) (N = 5) metabolic rate. For group L, exercise involved walking on a treadmill at 4 km/h 1(-) with a 0% grade. Group H walked continuously at 4.8 km/h 1(-) with a 3% grade. Trials were conducted in a environmental chamber at 40C and 25% relative humidity. TRUNCATED
