Abstract

Objective:To describe physiological responses of mine rescuers during a simulated mine emergency.Methods:Body-worn monitors (n = 74) and core temperature (T_c) capsules (n = 54) assessed heart rate (HR), respiration rate (RR), energy expenditure (EE), oxygen consumption (), T_c and skin temperature (T_skin), by team position and task. A multivariate analysis was performed with team positions, tasks, and measures as factors.Results:HR_mean and HR_peak were 78.6% and 94.5%, respectively, of predicted maximum heart rate. Arduous labor tasks elicited higher HR, RR, and than casualty care. Captains exhibited lower HR_mean, HR_peak, RR, RR_peak, T_c, and T_skin compared with other positions. T_{c mean} exceeded 38.6 °C (n = 14 recorded T_c >39 °C).Conclusions:Captains' physical loading and heat stress were lowest. Nonetheless, all tasks and positions induced high physical load and heat strain.
