| Abstract |
Electricity distribution controllers are responsible for balancing supply and demand for electricity under planned and unforeseen equipment shut-downs and network disruptions. To study the effects of stress on the cognitive performance and the cardiovascular system of controllers, 16 controllers working 12-hour shifts were studied. A five-point scale was used to estimate the perceived level of stress. The most pronounced changes in heart rate, circulatory minute volume and Kerdo's vegetative index were found during the first day shift and less pronounced changes appeared during the first night shift. Effects of stress on the studied parameters were not found during the second consecutive day or night shift. Increased stress causes the activation of psychophysiological functions that are indispensable for ensuring work efficiency under increased production demands. However, the necessary activation could not be maintained during the second consecutive 12-hour shifts. There was no observed effect of stress on short-term memory. |
