Involuntary nervous system functional state of employees, doing the night shifts

A study of 22 men, working on schedule with night shifts was carried out; average age 35.3±4.1 the average length of service - 10.2±3.1. and of 28 men working without night shifts; average age 37.9±3.3 l (p>0.05), the average length of service - 13.2±3.2 l (p>0.05). The surveillance program included a clinical assessment of the involuntary nervous system by questionnaire of A.M. Wayne and heart rate variability assessment, which includes the estimation of the spectral analysis klinostaze functional indicators, as follows: power value of the high-frequency component spectrum (HF,%) and the characteristic value dependencies of the low-frequency and high-frequency components (LF / HF). It was established that employees who work on a labour routine with night shifts, have a decrease in the activity of autonomic regulation and low reserve of the adaptive protection mechanisms.
