Estimation of Functional Condition of Heart Rate Vegetative Regulation in Primary Schoolchildren

Abstract

Spectral parameters of the heart rate variability in 218 children (111 boys and 107 girls) have been estimated with use of various test loads. There have been detected functional features of regulatory structures’ (controlling the heart rate) reactions to intellectual and physical loads depending on age and levels of intellectual and physical working capacity. The data on heterochronous nature of maturation of structures responsible for the heart rate regulation during mental and physical activity in primary school children have been received.
