[Systems evaluation of physiological functions of humans at a workplace]

The paper gives experimental findings of the application of the Anokhin theory of functional systems to the evaluation of human physiological functions in a working place. It is shown that the correlations of the heart and respiration rates with the effective productive activity quanta may characterize the specific features of autonomic regulation in workers and objectively suggest the occurrence of their psychoemotional stress in their working place. Disintegrated autonomic correlations in the productive activity quanta reflects impaired multicomponent interactions of homeostatic functional parameters, by ultimately causing an abnormality.
