[Assessment of physical and psychological strain during the climbing up of high broadcasting masts using physiological parameters].

Heart rate, breathing rate, electromyogram, skin resistance and skin temperature were measured when 11 experienced technicians climbed up a mast of 135 m height by means of a digital memory system, a new method for recording demand profiles. To separate physical and psychological strain the same parameters were measured in a laboratory simulating the physical strain with a bicycle ergometer. It could be shown, using non-parametric statistical methods, that the short-time physical strain seems to be superimposed by an emotional component.
