||Heat strain at the critical WBGT and the effects of gender, clothing and metabolic rate
||July 2008, Vol.38, No.7-8, p.640-644. Illus. 25 ref.
||Twenty nine participants (20 men and 9 women) walked on a treadmill at a moderate metabolic rate, wearing five different clothing ensembles. Furthermore, a subset of 15 participants (11 men and 4 women) completed trials for all ensembles at low and high metabolic rates, using a progressive heat stress protocol. The critical WBGT (WBGTcrit) was defined as being the WBGT index 5min prior to a loss of thermal equilibrium and represents the upper limit of thermoregulatory control. As expected, there was an ensemble effect and metabolic rate effect for WBGTcrit. The metabolic rate also had significant effects on heat strain. After adjustment, there was no gender effect for WBGTcrit or skin temperature. There were, however, significant gender effects for heart rate, core temperature and physiological strain index. Other findings are discussed.
