Abstract

In 102 conditionally healthy volunteers aged from 19 to 30 years (average age is 19,53 ± 11 years) the volatility of heart rate variability (HRV) spectral parameters depending on body mass index (BMI) were evaluated. According to WHO recommendations on the calculation and interpretation of BMI were such groups of volunteers: underweight, normal body weight, overweight, obesity I degree, obesity II degree, obesity III degree. Among HRV parameters were evaluated total power (TP, ms2), power of very low frequency (VLF, ms2), low frequency (LF, ms2) and high frequency (HF, ms2) domains of HRV spectrum in the 5-minute intervals of ECG in I standard lead. The data were processed by methods of nonparametric statistics. It was established that spectral characteristics of HRV in volunteers with normal BMI have a high TP with harmonious relations between VLF, LF and HF domains; decreased or increased BMI provokes TP reduction by decreasing power of all domains of HRV (VLF, LF, HF) with a predominance of VLF proportion and this effect increases with the degree of deviation of the parameter.
