Table 3 A comparison of the time course and rate of core temperature change at the onset or cessation of exercise when measured at oesophageal, intestinal and rectal sites.

Oesophageal Intestinal Rectal
Time for 0.1°C change from start of exercise (min)
 Kolka et al,13 40% VO2peak 4.4 (2.7)* 7.5 (4.8)† 12.3 (3)
 Kolka et al,13 80% VO2peak 1.8 (0.8)* 3.8 (1.5)† >5.0 (0)
 Lee et al,17 40% VO2peak 10 (1.1) 14 (1.2) 15.7 (1.6)‡
Rate of change during exercise (°C/min)
 Kolka et al,14 40% VO2peak 0.050 (0.013)* 0.031 (0.014) 0.018 (0.005)
 Kolka et al,14 80% VO2peak 0.112 (0.028)* 0.066 (0.035)† 0.018 (0.009)
 Lee et al,17 40% VO2peak 0.022 (0.005) 0.021 (0.004) 0.016 (0.004)
Time to steady‐state temperature during exercise (min)
 Kolka et al,13 40% VO2peak 18.0 (6.1) 25.2 (9.1)† 37.3 (4.6)‡
Time for 0.1°C change from end of exercise (min)
 Kolka et al,13 from 40% VO2peak 2.3 (0.5)* 6.5 (3.1)† 12.2 (3.3)
 Lee et al,17 from 65% VO2peak 3.7 (0.4) 7.1 (1.5) 10.6 (1.9)‡
Rate of change during recovery (°C/min)
 Lee et al,17 from 65% VO2peak −0.030 (0.002)* −0.023 (0.003)† −0.010 (0.003)

Values are mean (SD).

*Toesophageal significantly different from Tintestinal and Trectal, p<0.05.

†Tintestinal significantly different from Trectal p<0.05.

‡Trectal significantly different from Toesophageal, p<0.05.
