ABSTRACT
Workload and Internal Temperature. This step also allowed to identify variables to monitorize (Costa et al., 2012a), for example, skin and core temperature, cerebral electrical activity, heart rate, muscle electrical activity, electrodermal activity; dehydration, as well as subjective variables evaluated by specific questionnaires. Bearing in mind the purpose of the study, the priority was given to the articles approved by the ethics committees of the respective organizations or, at least, with informed consent. Other selection criteria were the calibration/validation of the equipments, usability, reability, comfort under use and the possibility of monitorization in real time.
