| Abstract |
The purpose of this study was to compare a vapour compression microclimate cooling system (MCC) and a personal ice cooling system (PIC) for their effectiveness in reducing physiological strain when used with cooling garments worn under the impermeable self-contained toxic environment protective outfit (STEPO). A second comparison was done between the use of total body and hooded shirt-only cooling garments with both the MCC and PIC systems. Eight subjects (six men, two women) attempted four experiments at 38°C, 30% rh, 0.9m/sec wind, while wearing the STEPO. Subjects attempted four hours of treadmill walking (rest/exercise cycles of 10/20min) at a time-weighted metabolic rate of 303±50W. It was found that the total body circulating liquid cooling was more effective than shirt-only cooling under the impermeable STEPO uniform. The MCC and PIC systems were equally effective during heat exposure, but neither system could allow reaching the four-hour targeted time. |
