A Heart Rate Based Algorithm to Estimate Core Temperature Responses in Elite Athletes Exercising in the Heat.

Purpose: Non-invasive non-obtrusive continuous and real-time monitoring of core temperature (T) may enhance pacing strategies, the efficacy of heat mitigation measures, and early identification of athletes at risk for heat-related disorders. The Estimated Core Temperature (ECTemp™) algorithm uses sequential heart rate (HR) values to predict T. We examined the validity of ECTemp™ among elite athletes exercising in the heat.

[Exertional heat stroke in athletes and soldiers].

Exertional heat stroke (EHS) is a medical emergency characterized by life-threatening hyperthermia and central nerve system dysfunction during or directly after exercise. Early recognition and aggressive cooling reduces morbidity and mortality of patients with EHS. Therefore, all health care professionals involved in acute care should immediately recognise EHS and start cooling with cold water immersion as soon as possible.
