Abstract : The effects of saline or atropine injection (2 mg, im) on eccrine sweating and performance time in seven healthy male subjects were evaluated during treadmill walking in a hot-dry environment, before and after heat acclimation. Mean skin temperature, rectal temperature, and heart rate were continuously measured. Data demonstrated that heat acclimation improves the endurance time of atropine-treated subjects in a hot-dry environment. This improvement was in part due to the potentiation of sweat gland activity enabling greater evaporative cooling for the same dose of atropine.
