[The assessment of body functional systems by the indices of their nonspecific reactions].

The analysis of long standing researches in the military operators' procedure has shown some regularities in the changes of indices which were examined. Varying in time and magnitude the non-specific reactions at first manifest itself in unstable vegetative regulations, then proliferate its influence upon visual and motor coordination, and finally cause negative shifts in professional activities (worsening of accuracy and precision, appearance of errors, etc). It is obvious, that specific reactions impose their own features on the development of this program without changing its basic trend.
