[Working conditions and functional body stress of operators in the television video recording centers].
In order to determine the ways for prevention of operators' overstrain, the working conditions and functional body stress were dynamically studied during the 12-hour shift by means of TV video-recording. The majority of operators experienced some neurologic disorders, high rates of situational and personality anxiety and an elevated level of neurotism. Mean rate of potential systoles was 75 +/- 2 per min, systolic arterial pressure 114 +/- 2, diastolic AP 74 +/- 2 mm of mercury column. No renewable dynamics of the above indicators was noted. The Kerdau vegetative index experienced a decline from + 6.0 +/- 2.5 to -6.5 +/- 3.0 arbitrary units during the shift. The regulatory system strain index in the half of the examined workers reached 300AU. The speed of data processing remained stable during the shift. To its end the critical fusion frequency on the peripheric visual field and remote visual thresholds decreased and differentiated achromatic thresholds increased. The level of operators' functional body strain could be regarded as admissible. The above characteristics of load response of some physiologic systems were assumed to be variants of an adaptable norm. The proposed preventive measures assisted in decreasing operators' functional body strain.
