Effectiveness of a light-weight ice-vest for body cooling while wearing fire fighter’s protective clothing in the heat
Författare
Summary, in English
The aim of the study was to examine the effects of wearing an ice-vest (ca 1 kg) on physiological and subjective responses in fire fighters. The experiments were carried out on a treadmill in a hot-dry environment. The physical cooling effect of the ice-vest was measured with a thermal manikin. The ice-vest effectively reduced skin temperatures under the vest. On average, heart rate was 10 beats min-1 lower, amount of sweating was reduced by 13%, and subjective sensation of effort and warmth were lower during work with the ice-vest compared to work without it. Thermal manikin tests indicated, that the useful energy available from the vest for body cooling was rather high (58%). In conclusion, the ice-vest reduces physiological and subjective strain responses during heavy work in the heat, and may promote efficient work time by 10%.
