Body temperatures measured in the esophagus and rectum during, A, rest, B, exercise, C, cold-water immersion, and D, postimmersion recovery (mean ± standard deviation; n = 17). Abbreviations: T4cm, rectal temperature 4 cm from the anal sphincter; T10cm, rectal temperature 10 cm from the anal sphincter; T15cm, rectal temperature 15 cm from the anal sphincter; Teso, esophageal temperature. a Indicates T4cm was different from Teso within each time point (P < .05). b Indicates T10cm was different from Teso within each time point (P < .05). c Indicates T15cm was different from Teso within each time point (P < .05).
