The peculiarities of heart rate variability in female adolescents of different somatotypes living in the Carpathians it is studied. The increasing total power heart rate spectrum and its components (TP, ms2; HF, ms2; LF, ms2) in mesomorphic type girls aged 13–14 and increasing of high-frequency component (HF norm, %) in ectomorphic somatotype adolescents aged 14–15 which preceded the periods of regulatory systems is found. In endomorphic somatotype persons the highest stress regulation mechanisms is found in 12 years, from 13 to 15 years was observed a gradual increase of total power spectrum of heart rate, which was accompanied by a decrease of contribution of sympathetic (LF norm, %) and increase of parasympathetic (HF norm, %) influences.
