Changes in the Heart Rate Parameters under the Influence of Academic School Activities in Adolescents with Mental Retardation

  • N. P. Gorbunov


Examination of seventh-grade schoolchildren revealed that changes in the heart rate parameters observed during a day or a week in mentally retarded (MR) adolescents have some specific features as compared with values in healthy children of the same age. Appreciable variations of power in all frequency bands and a pronounced decrease in the low-frequency spectrum power at the end of the day were characteristic of MR schoolchildren. In the middle of the week, the tone of the sympathetic nervous system dropped, while adaptive changes in the level of psychoemotional tension were not observed. In healthy adolescents, the heart rate parameters were stable throughout a school day or week, whereas psychoemotional tension rose in the middle of the week. These results provide a basis for modification of the learning regimen in correctional schools. Heart rate analysis may be used for assessing the efficiency of the academic process in children with learning problems.
