Mean ± SD Measures of rectal and muscle temperature thermal measures during exercise-heat stress (n = 10)
| Measure | Peak rectal temperature (°C) | Mean rectal temperature final 60 min (°C) | Change in rectal temperature (°C) | Rate of rectal temperature increase (°C h−1) | AUC for rectal temperature of 38.5 °C (°C min−1) | AUC for rectal temperature of 39.0 °C (°C min−1) | Duration rectal temperature ≥38.5 °C (min) | Duration rectal temperature ≥39.0 °C (min) | End muscle temperature (°C) | Change in muscle temperature (°C) |
