Abstract |
Eight subjects performed treadmill walking alternating with rest periods under three conditions: control, light clothing only; chemical protective ensemble (CPE); and CPE plus a personal cooling vest to allow for intermittent cooling by circulation of chilled liquid. Under the control condition, relatively modest changes in rectal temperature were observed. CPE wear resulted in a progressive rise in temperature and early fatigue. The addition of intermittent cooling during each rest cycle significantly attenuated heat storage and work capacity was at least doubled. Intermittent personal cooling provides a useful means of enhancing work productivity during heavy work in hot environments. |
