HEART RATE VARIABILITY IN CHILDREN AGED 8-10 YEARS WITH VARIOUS TYPES OF SOMATIC CONSTITUTION IN THE PROCESS OF COGNITIVE ACTIVITY
Cardiointervalography investigated temporal and spectral characteristics of heart rate in primary school children with thoracic and muscular body type under the influence of different functional loads. The correlation and regression analysis revealed a relationship between the type of somatic constitution and parameters of heart rate variability.
