Abstract:
The assessment of the regulatory systems of the body of children in the early childhood was conducted by using
physiological and clinical examination in junior classes of secondary school. Morphological and functional
development of children was evaluated in terms of height, body weight, cardiovascular system was assessed
by changes in heart rate, SBP, DBP, PP, ECG, systolic blood volume (SV) and blood oxygenation.
State of regulatory systems was measured by heart rate variability (HRV), analyzing the common basic parameters
of cardiointervalography: M, IC, Mo, Amo, VR and their derivative indicators by R.M.Baevsky:
VIR (vegetative index rate), VBI (vegetative balance index), SI (index of regulatory systems stress) ARP (adequacy
of regulation processes).
