Abstract

Professional operator practice is characterized by conditions of increased complexity and is associated with the constant action of stressors, which contributes to the development of fatigue. One of the manifestations of sustained fatigue is autonomic dysfunction. Methods. 250 healthy men aged 18–25 years were trained in operator skills using the test «Smile». After establishing a stable result a study was conducted of the effectiveness of sensorimotor tracking in complicated conditions for 60 minutes. Heart rate variability was recorded during all three periods of the stress test «fall from the knees». Results. Operators were divided into two groups due to the presence of fatigue. The frequency parameters were significant at all periods of stress test. Conclusion. The criteria for the critical operator fatigue were revealed as a result of sensorimotor tracking. Autonomic reactivity during stress test was associated with performance in activity modeling.

Keywords
