Comparison of Whole-Body Cooling Techniques for Athletes and Military Personnel.
The purpose of this study was to evaluate cooling rates of The Polar Life Pod®, a military protocol and cold water immersion. A randomized, repeated measures design was used to compare three treatment options. Participants exercised in an environmental chamber, where they followed a military march protocol on a treadmill, followed by the application of one of three treatments: Cold water immersion tub (5 - 10 °C), Polar Life Pod® (5 - 10 °C), Ice sheets at onset (5 - 10 °C). Mean cooling rate for CWI was 0.072 ºC/min, 0.046ºC/min for ice sheets, and 0.040ºC/min for The Polar Life Pod®. There was a significant difference between conditions (F2,26=13.564, p=0.001, ES=0.511, 1-β=0.969). There was a significant difference in cooling rate among The Polar Life Pod®and CWI (p = 0.006), and no significant difference among The Polar Life Pod®and Ice Sheets (p = 0.103). There was a significant difference of time to cool among the three conditions F2,26= 13.564, p = 0.001, ES = 0.401, 1-β = 0.950. Our results support multiple organizations that deem CWI as the only acceptable treatment, when compared to the cooling rates of The Polar Life Pod®and ice sheets.
