Intermittent whole-body cold immersion induces similar thermal stress but different motor and cognitive responses between males and females

•The thermal response to intermittent cold (IC)-induced stress was similar in both sexes.•Maximal isometric voluntary contraction decreased after IC only in males.•The responses of involuntary muscle properties to IC were similar in both sexes.•Spinal and supraspinal reflexes after IC did not differ...

Description
Summary:•The thermal response to intermittent cold (IC)-induced stress was similar in both sexes.•Maximal isometric voluntary contraction decreased after IC only in males.•The responses of involuntary muscle properties to IC were similar in both sexes.•Spinal and supraspinal reflexes after IC did not differ between sexes.•IC-induced perturbation of cognitive function was greater in males than in females. The main aim of this study was to compare the thermal responses and the responses of cognitive and motor functions to intermittent cold stress between males and females. The intermittent cold stress continued until rectal temperature (TRE) reached 35.5°C or for a maximum of 170min. Thermal response and motor and cognitive performance were monitored. During intermittent cold stress, body temperature variables decreased in all subjects (P
