Do mental and physical loads alter spectral parameters of heart rate variability in primary schoolchildren?
Do mental and physical loads alter spectral parameters of heart rate variability in primary schoolchildren?
Mental and physical loads induce significant reductions in absolute spectral power of heart rate variability in primary schoolchildren, reflecting the maturation of autonomic regulatory structures.
HRV spectral power reductions during loads in schoolchildren; leaves open clinical utility pending longitudinal validation.
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.
