Regulation of work is a complex social and biologic task including two independent but associated aspects. The first one is technical and economic regulation orientated to work results, and the second one, ergonomic, considers influence of work on human body. Regulation of work and consumption is based on a compromise between those two aspects. Ergonomic regulation covers such characteristics of work, as load and intensity, jeopardy and hazard, lack of attractiveness and prestige, therefore 3 subunits of ergonomic regulation are physiologic, hygienic and psychologic. Physiologic regulation is designed to set maximal allowable load (by restricting extremely high and low values which harm health) and optimum one (to improve physical and psychic abilities, activate resources for functional efforts).
