[Comparative analysis of methods evaluating ergonomic risks].
The authors demonstrated appropriateness of some subjective methods evaluating strain in workers engaged into road building and determined work hardiness categories, considering peculiarities of individual methods. Calculations using empiric equations covered energy consumption during workers' dynamic activities. Empiric equations were proved to point to higher energy consumption, if compared to results of experimental methods. Objective evaluation of work hardiness involved heart rhythm monitoring through a device transforming heart rate into metabolic energy, kcal/min.
