The accuracy of core temperature (T) thermometry from temporal, tympanic, and oral thermometry devices has been variable during exercise in a hot, humid environment. The purpose of the present study was to cross-validate temporal, two tympanic devices, and oral devices compared to an ingestible thermistor during exercise in a hot, humid environment. Fourteen young, active adults (6 women) completed a graded exercise test until voluntary exhaustion in an environmental chamber (35.5 ± 0.6 °C, 53.9 ± 5.8 % RH). There was no statistical difference in mean temperature between tympanic device 1 and pill-based core temperature (PBT) measurements across all time points and were positively correlated (0.357; P<0.001). Temperatures of tympanic device 2 were statistically higher than PBT (37.8 ± 0.7 ºC vs. 37.6 ± 1.0 ºC; respectfully) (P=0.008). At all time points, temperatures for the second tympanic device and PBT were positively correlated (0.192; P=0.043). Temporal and PBT values did not differ across time points and were positively correlated (0.262; P=0.005) across all time points. Mean oral temperature was significantly less than mean PBT across all time points. (37.0 ± 0.4 ºC vs. 37.6 ± 1.0 ºC, respectively) (P<0.001). Across all time points, oral and PBT were positively correlated (0.262; P=0.010). Tympanic and temporal devices can reflect T while exercising in a hot, humid environment. However, care should be taken when selecting the tympanic or temporal measurement device and validation is advised prior to heat illness mitigation in the field.
在炎热潮湿环境中运动期间，颞部、鼓膜和口腔体温计测量核心体温（T）的准确性一直存在差异。本研究的目的是在炎热潮湿环境中运动期间，将颞部体温计、两种鼓膜体温计和口腔体温计与可摄入式热敏电阻进行交叉验证。14名年轻、活跃的成年人（6名女性）在环境舱（35.5±0.6°C，53.9±5.8%相对湿度）中完成了分级运动测试，直至自愿力竭。在所有时间点，鼓膜体温计1与基于药丸的核心体温（PBT）测量值之间的平均温度无统计学差异，且呈正相关（0.357；P<0.001）。鼓膜体温计2的温度在统计学上高于PBT（分别为37.8±0.7ºC和37.6±1.0ºC）（P=0.008）。在所有时间点，第二种鼓膜体温计与PBT的温度呈正相关（0.192；P=0.043）。颞部体温计与PBT的值在各时间点无差异，且在所有时间点呈正相关（0.262；P=0.005）。在所有时间点，平均口腔温度显著低于平均PBT（分别为37.0±0.4ºC和37.6±1.0ºC）（P<0.001）。在所有时间点，口腔温度与PBT呈正相关（0.262；P=0.010）。在炎热潮湿环境中运动时，鼓膜和颞部体温计可以反映核心体温。然而，在选择鼓膜或颞部测量设备时应谨慎，并建议在野外预防中暑之前进行验证。
