“…training in sweat suits in cooler conditions [272]). The physiological changes commonly observed with heat acclimation include an increased sweat rate, lowered heart rate, and lowered core and skin temperature [187,318,320], as well as decreased ratings of perceived exertion and thermal sensation [321], decreased sodium content of sweat and an expansion of plasma volume [322] being reported. Sigmlicant changes in cognitive performance during heat acclimatisation regimes have also been reported, suggesting that tasks requiring the acquisition of new behaviours may be ditticult to perform in a hot environment [323].…”
