^aAverage of all rectal depths within each time (ie, main effect of time).

^bAverage of all measurements collected during the experiment at each depth (ie, main effect of rectal depth).

^cLess than cooling period (P < .05).

^dLess than postimmersion recovery (P < .05).

^eLess than rectal temperature at 4 cm from the anal sphincter (P < .05).
