[Principles and methods of evaluating tension of the functional systems in the body during work].

Grounded and worded concept stresses that the intensity of regulating mechanisms must be taken into account in evaluating the difficulty and intensity of work, criteria of intensity are suggested. Growth of intensity index, centralized administration or considerable number of correlations (above the average on the whole industry) and more synchronized functions during the work improve the intensity of work by one step above the results of the simple physiological evaluation of work intensity.
