to determine the correlation of umbilical temperatures (T) with simultaneously recorded chest wall temperature (T) and rectal temperature (T) in adults during rest, heat exposure and exercise.
A total of 28 healthy men, wearing different types of clothing (athletic garb, a spandex full body heating garment, firefighter bunker gear) had average and peak umbilical, chest wall and rectal temperature measurements taken during sedentary temperature stabilisation stages, heat exposure periods and active exercise phases.
Curvilinear relationships were noted between T and T compared with T and their association became noticeably positive and linear at approximately 35.5 °C. Polynomial regression analysis of T with linear and quadratic forms of T and T indicated an overall R of 0.657 and 0.767, respectively. Bivariate analysis of a restricted data set (where T and T ≥35.5°), indicated that T was significantly associated with T (r = 0.710, p <0.001; r = 0.841, p <0.001) and T was also significantly associated with T, but less so (r = 0.570, p <0.001; r = 0.699, p <0.001).
the umbilicus offers a non-invasive, peripheral site for measurement of temperature that more closely correlated with body core temperature than T when core temperature was ≥35.5 °C.
在休息、热暴露和运动期间，确定成人脐温（T）与同时记录的胸壁温度（T）和直肠温度（T）的相关性。
共有 28 名健康男性，穿着不同类型的衣服（运动服、紧身全身加热服、消防战斗服），在静息温度稳定阶段、热暴露期间和主动运动阶段，对平均和峰值脐、胸壁和直肠温度进行测量。
与 T 相比，T 与 T 之间呈曲线关系，当 T 达到约 35.5°C 时，其相关性明显呈正线性。T 与 T 的线性和二次形式的多项式回归分析表明，总体 R 分别为 0.657 和 0.767。对 T 和 T ≥35.5°C 的受限数据集进行的双变量分析表明，T 与 T 显著相关（r=0.710，p<0.001；r=0.841，p<0.001），T 与 T 也显著相关，但相关性较低（r=0.570，p<0.001；r=0.699，p<0.001）。
脐部是一种非侵入性的外周部位，当核心温度≥35.5°C 时，脐温比 T 更能与核心体温密切相关。
