OBJECTIVE
To describe physiological responses of mine rescuers during a simulated mine emergency.
METHODS
Body-worn monitors (n = 74) and core temperature (Tc) capsules (n = 54) assessed heart rate (HR), respiration rate (RR), energy expenditure (EE), oxygen consumption ((Equation is included in full-text article.)), Tc and skin temperature (Tskin), by team position and task. A multivariate analysis was performed with team positions, tasks, and measures as factors.
RESULTS
HRmean and HRpeak were 78.6% and 94.5%, respectively, of predicted maximum heart rate. Arduous labor tasks elicited higher HR, RR, and (Equation is included in full-text article.)than casualty care. Captains exhibited lower HRmean, HRpeak, RR, RRpeak, (Equation is included in full-text article.), Tc, and Tskin compared with other positions. Tc mean exceeded 38.6 °C (n = 14 recorded Tc >39 °C).
CONCLUSIONS
Captains' physical loading and heat stress were lowest. Nonetheless, all tasks and positions induced high physical load and heat strain.
目的
描述矿山救援人员在模拟矿山紧急情况下的生理反应。
方法
通过团队位置和任务，对佩戴在身上的监测器（n=74）和核心温度胶囊（n=54）进行心率（HR）、呼吸频率（RR）、能量消耗（EE）、耗氧量（（方程式包含在全文中。））、核心温度（Tc）和皮肤温度（Tskin）的评估。采用多元分析法对团队位置、任务和措施进行了分析。
结果
HRmean 和 HRpeak 分别为预测最大心率的 78.6%和 94.5%。艰苦的劳动任务比伤员护理引起更高的 HR、RR 和（方程式包含在全文中。）。与其他职位相比，队长的 HRmean、HRpeak、RR、RRpeak、（方程式包含在全文中。）、Tc 和 Tskin 较低。有 14 人记录的 Tc 超过 38.6°C（n=14）。
结论
队长的体力负荷和热应激最低。尽管如此，所有的任务和职位都导致了高强度的体力负荷和热应激。
