Girls (n=86; age 5-17 yrs) - Graphs No 1-34: in supine 1-17, standing 18-34 Boys (n=62; age 5-14 yrs) - Graphs No 35-68: supine 35-51, standing 52-68 Note: The percentiles´ equations are results of a 6th grade polynomic regression.

HRV parameters from 5 minute intervals TP (ms ) - total power (celkový spektrální výkon) P-VLF (ms2, %) – spectral power of very low frequency band (spektrální výkon pásma velmi nízkých frekvencí) P-LF (ms2, %, nu) – spectral power of low frequency band (spektrální výkon pásma nízkých frekvencí) P-HF (ms2, %, nu) – spectral power of high frequency band (spektrální výkon pásma vysokých frekvencí) PSD-VLF (ms2∙Hz-1) – power density of very low frequency band (výkonová hustota pásma velmi nízkých frekvencí) PSD-LF (ms2∙Hz-1) – power density of low frequency band (výkonová hustota pásma nízkých frekvencí) PSD-HF (ms2∙Hz-1) – power density of high frequency band (výkonová hustota pásma vysokých frekvencí) SDRR (s) – standard deviation of R-R intervals (směrodatná odchylka R-R intervalů) CVRR (%) – coefficient of the RR variance; relative standard deviation of R-R intervals (variační koeficient R-R intervalů – poměr směrodatné odchylky k průměru R-R intervalů) MSSD (ms2) – mean square of successive differences (průměr druhých mocnin rozdílů po sobě jdoucích R-R intervalů) RR (s) – mean of the R-R intervals (průměr R-R intervalů) HR (b∙min-1) – heart rate (srdeční frekvence) 2
