Abstract:

This study evaluated the efficacy of a thermoelectric TE cooling vest developed by AFRLRX incorporating P-N junction elements. This vest is designed for military personnel that work in hot environments above 87 deg F and was designed to decrease core body temperature and increase vigilance. A series of tests were completed using eleven subjects. Efficacy of the vest was determined by running baseline maximal oxygen uptake VO2max on each subject and designing a subject-specific submaximal test with a vigilance task. Each subject completed a total of four submaximal tests wearing the vest on twice and off twice. Analysis of both the core body temperature and the vigilance of the subjects did not find a significant statistical difference of the vest on versus off or vesttime interaction. There was a significant effect of time on core body temperature, which is to be expected due to increased physical workload over time regardless of the vest.
