[Changes in the matching of somato-autonomic rhythms in the human operator during learning]

In subjects during the 1st through 15th day of training of the assemble job, before and during the work, the changes of concordance between the heart rate and respiration rhythm were studied in comparison with the dynamics of the activity results and of psychophysiological characteristics. In subjects with bad results of learning higher indices of respiratory-cardiac concordance and tremor were initially observed, what may serve as a criterion for professional selection for this kind of activity. In well learning subjects during transition from rest to work the initial desynchronization of somato-vegetative rhythms ("stress" type of reaction) was changed by an increase of their concordance. The relation of the training success to the type of working capacity of the subject ("morning", "evening") was also revealed.
