In the last thirty years work load has become more a load on the mental capacities of the human operator rather than on his physical capabilities. There is a growing number of activities in which the operator is assigned jobs that involve monitoring and/or supervisory control of complex systems or problem solving of different kinds.

Firefighters face significant physical and psychological hazards, which increases their risk of developing adverse mental health outcomes, such as depression, anxiety, and suicidal ideation. Despite growing behavioral health awareness, significant gaps remain regarding the mental health landscape of the fire service, the role of organizational safety ...

Hemodynamic responses to mental stress during salt loading
Clinical Physiology and Functional Imaging, 2016SummaryPurposeThe purpose was to examine whether prolonged moderate stress associated with a student exam would increase the blood pressure response to a salt load in young healthy normotensive individuals.MethodsTen healthy young subjects were examined at two different occasions in random order (i) during preparation for a medical exam (prolonged ...

Subjective Aspects of Physical and Mental Load
Ergonomics, 1978Abstract Methods of measuring subjective difficulty, effort and other aspects of work-load which have been developed by the author and his colleagues are described, and the use of these methods as means of distinguishing between individuals, and their relationships to psychometric measures, are discussed.

The influence of mental load on muscle tension
Ergonomics, 2013We examined the differences in muscle tension and in physiological measures depending on the type of mental task. Fifteen participants performed tests for sustained attention, vigilance and maintaining posture only. We analysed electromyogram (EMG) measures of extensor digitorum (ED), flexor carpi ulnaris (FU), deltoideus (DE) and trapezius (TR), and ...

Spectral Analysis of Sinus Arrhythmia during Mental Loading
Ergonomics, 1975A technique is presented for digitally processing cardiac intervals to produce the low-pass filtered cardiac event sequence (LPFCES), a regularly sampled (in time) band-limited signal, representing in a standard form the information contained in the cardiac intervals. The technique takes into account the physiological mechanisms of information transfer

Mental Load and the Measurement of Heart Rate Variability
Ergonomics, 1973A number of studies concerning heart rate variability and mental load arereviewed It is concluded that in paced choice reaction tasks the number of reversal pointsin the cardiotachogram is the most sensitive measure of the load of the task.This measure was strongly correlated with respiration Spectral analysis of heart rate variability revealed the ...

Most of the traffic accidents have been caused by inappropriate driver's mental state. Therefore, driver monitoring is one of the most important challenges to prevent traffic accidents. Some studies for evaluating the driver's mental state while driving have been reported; however driver's mental state should be estimated in real-time in the future ...

This paper aims to present an analysis of the concept of mental load from the point of view of human performance theory. In the first section the theoretical status of the concept of mental load is considered. It is concluded that it is based upon common sense, which cannot be supposed to be empirically founded in a simple way. Then an outline is given
