[Effect of the type of work on the correlation between the subjective and objective evaluation of the workload]

This paper is aimed at the determination of the relationship between the heart rate and results of subjective rating of the workload in women working in the forming and sewing workrooms of the hosiery plant. The work in these workrooms differed in respect of organization, degree of motorial activity, type of activities performed, and working conditions. The subjective rating involved 22 symptoms evaluated three times during a working day, by a 5 -- degree scale. During the same periods heart rate was determined telemetrically. In forming women, heart rate was higher by approx. 11%, and average rating by around 7%, as compared to sewing women. In both groups a positive correlation was found between the heart rate and symptoms typical of general fatigue and working conditions. On the other hand, the correlation between symptoms of monotony sensation and rating of hands efficiency was negative. The correlation between the heart rate and average rating was positive in forming women and negative in sewing women, which indicates that the similar total rating of the workload resulted form different causes (general fatigue and working conditions in forming women and monotony sensation and a great number of hands movements in sewing women.)
