Adaptation Mechanisms of Shift Workers in Areas of the Far North

Abstract

One uses the labor migration in various sectors of the economy. A high degree of stress on the health of
shift workers leads to rapid fatigue and the development of irreversible pathology. Within the observation
of two groups during the 52-day shift, the 1st group-before the start of shift work, the 2nd group - after the
completion of shift labor organization, one put the labor activity under study, and there was time study of
key functions performed by workers. The body of shift workers functions with a constant level of stress in
regard to regulatory adaptation mechanisms to the circumstances of the industrial and climatic environment.
In the study of employees ‘ health, there was a decrease in performance at the end of the 1st month of shift
work with confirmed Vascular and autonomic dysfunctions within the cardiointervalography. In accordance
with the cardiointervalography and measured physical strength by the method of dynamometry, there were
dynamic indicators in groups at the stage of warming-up and during the completion of works. The study
of cardiointervalography revealed a negative impact of labour conditions on the cardiovascular system. In
accordance with the results of the study, the proposals may increase the workforce productivity.
