Correction of deviations of psycho-physiological status of hazardous occupations specialists with use of hypoxic gas-air environments.

Abstract

The study included 26 hazardous occupations specialists (men aged 20-32 years old), with signs of abnormalities of the psycho-physiological status (PPS) involved in intensive work. In the basic group (BG) (n=14) the specialists were trained with use of hypoxic artificial gas-air environments -HAGAE (O 2 content 15-17 %, duration of each procedure 45 min, the total number of procedures 12). For 12 people (the comparison group - CG), HAGAE conditions were simulated. PPS deviations were evaluated according to the state of the sensorimotor properties, the electroencephalographic (EEG) criteria, the level of reactive anxiety (RA). The studies in both groups were conducted prior to the correction measures (simulation) application, directly after the end of the program and in a month. In all individuals of the BG after the workouts, there was recorded an improvement of the PPS parameters compared to the initial level, such changes were absent in the CG, for which reason, there have been found statistically significant (p < 0.05) intergroup differences in a number of the sensorimotor parameters, the EEG criteria, the RA level. The program based on the use of HAGAE, can be regarded as a method of choice in restoring PPS of hazardous occupations specialists.
