Title A comparison of physiological responses to two types of particle barrier, vapor permeable clothing ensembles

Abstract The purpose of this study was to compare the effects on worker productivity of particle barrier, vapour permeable suits based on polyethylene (PE) and on polypropylene (PP). Fifteen male subjects performed four work tests consisting of a walk/arm curl combination, two in a wet bulb globe temperature (WBGT) of 26░C and two in a WBGT of 18░C, with subjects wearing each suit once in each environment. No significant difference was observed between the suits at 18░C WBGT, but a significant difference was found between the suits, with the PP having a lower Tre in the WBGT=26░C at the 80th, 100th and 120th min. A significant difference was also seen in the 26░C WBGT with the PP resulting in a lower heart rate (HR) at the 40th, 60th, 80th, 100th and 120th min and rate of perceived exertion (RPE) at the 75th, 90th and 120th min. Additionally, a significant difference was seen between PE and PP for Tre, delta Tre, mean skin temp (mTsk), delta mTsk and HR, each regressed against time in the 26░C WBGT. Twelve of the 15 subjects also reported feeling cooler in the PP versus the PE in either WBGT environment.
