Efficiency of three cooling methods for hyperthermic military personnel linked to water availability

Purpose: Three feasible cooling methods for treatment of hyperthermic individuals in the military, that differed considerably in water volume needed (none to ~80 L), were evaluated. Methods: Ten male soldiers were cooled following exercise-induced hyperthermia (rectal temperature (Tre) ∼39.5 °C) using ventilation by fanning (1.7 m s−1),...

Two isothermal challenges yield comparable physiological and subjective responses

Purpose: Ventilated vests are developed to reduce thermal stress by enhancing convective and evaporative cooling from skin tissue underneath the vest. The purpose of this study is to investigate whether thermal stress is equal when a ventilated vest is worn compared to a no-vest situation with similar dry thermal resistance. Methods: Nine...

Simulation of thermal cardiovascular strain using a thermophysiological model: Abstract

Introduction Exercise in a warm environment is typically correlated with a higher heart rate (HR) than the same exercise in a cool environment. In literature this effect is explained by the increased cardiac output (CO) due to increased skin blood flow, complemented with reductions in stroke volume (SV) due to venous pooling and dehydration....
