[Some biorhythm characteristics of personal adjustment of operators working in a shift regime].

Shift-work conditions for operators make it necessary to provide reliable and effective functioning of production processes at any time of a day opposite to the circadian periodicity of functioning activity which is imposed from outside and strengthened for years. Efficient levelling of the incoming circadian variations of the natural habitat determines the absence of intershift differences in the mental activity of operators. An increase in their expressiveness evidences a decrease in adjustment to the work in a shift regime. Different-in-principle ways to decrease adjustment to a shift-work of operators of different age and experience of work are revealed. Insufficient adaptation to a shift-work of young operators, starting their work in profession, is, as rule, accompanied by a distortion of the natural circadian biorhythm of speed of performance, an increase in conjugation of the intellect performance indices. A decrease in adaptation to a shift-work of senior-age operators is accompanied by an increase in expressiveness of the natural circadian biorhythm of speed of performance, by a decrease in conjugation of the performance indices.
