The purpose of this study was to investigate the effects of using an ice-vest and a palm cooling device on core and skin temperatures, heart rate, and perceived thermal comfort during a one hour recovery period following exercise in the heat. Ten recreationally active adults cycled for one hour at 50% V02 peak on a cycle ergometer while exposed to 36°C 45%relative humidity environmental conditions. Following exercise, each subjectwas exposed to an ice vest, a palm cooling device, or a non cooling control while seated in the environmental chamber for 60 more minutes. No significant differencewas found betweenany of the three recovery conditions with regards to change in rectal temperature (P = 0.61), heart rate (P = 0.13), or Gagge thermal sensation ratings (P = 0.56). The rate of core temperature decline in the recovery period was also not found to be different between the three conditions when assessed at 15, 30, 45, or 60 minutes. There was a significant difference between the change in skin temperature during the recovery period between the vest and non-cooling control condition (P = 0.004). The significant condition-by-time interaction indicated that the differences in change in skin temperature between vest and control existed specifically at 10, 15, 20, 25, 30, 45, and 55 minutes of recovery.
