Validity of a noninvasive estimation of deep body temperature when wearing personal protective equipment during exercise and recovery

摘要

BackgroundDeep body temperature is a critical indicator of heat strain. However, direct measures are often invasive, costly, and difficult to implement in the field. This study assessed the agreement between deep body temperature estimated from heart rate and that measured directly during repeated work bouts while wearing explosive ordnance disposal (EOD) protective clothing and during recovery.
