title: [Examination of spectral parameters of heart rate in junior schoolchildren at mental work].
abstract: Described in the paper are the results of a study of spectral parameters of variable heart rate (VHR) in 67 junior schoolchildren, aged 8-11, obtained alongside with the Landolt test. It was reliably demonstrated that the total capacity of the VHR spectrum and of spectral indices was decreased at the time of test; however, it went up subsequently to the initial level or topped it. The results of investigation of spectograms of VHR recorded in the course of the Landolt non-verbal test explain individual features related with the heart rate monitoring and with adaptive potentialities of schoolchildren.
