摘要

Fatigue of a human being and the consequence of it, reduction in professional efficiency, under the effect of acute disruption of the diurnal rhythm and of vital functions, appeared with an increase in time. Execution of professional functions and an increased instability of individual characteristics in executing these tasks also occurred. Maximum instability of individual characteristics (in comparison with initial data obtained under ordinary conditions), was observed during the execution of professional function and actions based on finely coordinated motorial activity. Fewer changes were observed when the individuals executed rapid actions connected with shifting of body in space. (Author)
