  • Title: [Adaptive potential of operators with various dynamics of fitness for work during a transition from day to night shift].
    Author: Sytnik NI.
    Journal: Fiziol Zh (1978); 1991; 37(5):98-102. PubMed ID: 1790824.
    Abstract:
    While transferring from day to night shifts 3 categories of changes in the working ability are revealed among the operators. It is stated that the working ability in 19% of operators decreases, in 62%--remains practically unchanged, in 19%--improves. The higher levels of arterial pressure, vascular peripheral resistance (in both shifts), the heart systole rate (day shift) are found in the first group of operators. The structure of correlations between the physiological functions is characterized by harder intrasystemic relations in the day shift as against that of other operators and by the increasing effects of the intersystemic interactions while decreasing intrasystemic relations in the night shift. The adaptive potentialities were higher in the second group and particularly in the third group of operators.
