Study Summary
Heat-related injuries and other physiological stresses continue to be a significant threat to the health and operational effectiveness of the US Armed Forces (Armed Forces Health Surveillance 2011). This is because military personnel are exposed to exertional and environmental heat-stress factors during both deployment and training at US installations in hot and humid climates. Cold water immersion (CWI) is considered the gold standard for the treatment of exertional heat stroke (EHS) and has been shown to increase survival rates to 100% with the implementation of CWI best practices. However, in a field setting other cooling strategies have been developed to aid in the prevention of EHS and other heat-related illnesses. One such proposed strategy is a portable hand cooling device that does not require the use of ice or water. Therefore, the primary purpose of this investigation is to validate hand and back cooling devices using physiological, cognitive, performance, and perceptual responses that occur during and following rest, exercise, and cooling in the heat.
Primary Outcome
Participants will be fitted with a Hans Rudolph mask attached to a breathing tube to measure the expired air delivered to the metabolic cart system during the exercise protocol. The metabolic cart will continuously measure oxygen consumption (VO2) to asess their VO2max value.
Interventions
- OTHER Passive cooling
- OTHER Hand Cooling at 12-15 degrees celsius
- OTHER Hand Cooling at 16-20 degrees celsius
- OTHER hand and back cooling at 12-15 or 16-20 degrees celsius
