[Covariance of the level of activation and work performance as a method of evaluating the work load].
Assuming as proved the claim that there is a relation between the activation level and the results of work performed, which may be presented by means of a curve bearing a reversed "U" shape, it has been assumed that we can think of a work load when there is a negative correlation between these parameters. This assumption has been checked by comparying work load of weaving women operating two different types of looms. As an index of activation level, the frequency heart rate has been taken, whereas the rapidity of work performance and results of interpolated tests (reaction time, centre-punching, dotting, drawing a line and accuracy of observation) have been treated as the indices of capability for work. Differences in the trend of interdependence between these groups of parameters, depending on the type of activity performed and the type of loom under description, have been found, which indicates that this method may possibly be used when evaluating the load as well as pointing out its sources.
