Abstract

The purpose of this research was to compare the differences in heart rate variability (HRV) parameters between obese and non-obese individuals from spontaneous breathing (SB) and paced breathing (PB). Totally 20 subjects, healthy male adolescents participated in the study: 10 obese (age: 17.1 ± 0.74 yrs; height: 173.5 ± 4.94 cm; weight: 103.9 ± 16.4 kg; %BF =29.0 ± 5.68; waist circumference (WC): 102.8 ± 7.8 cm; systolic blood pressure (SBP): 119.2 ± 5.9 mmHg; diastolic blood pressure (DBP): 74.6 ± 6.7; physical activity level: 36.9 ± 9.48) and 10 non-obese (age:16.5 ± 0.71 yrs; height: 166.7 ± 5.33 cm; weight: 55.1 ± 106 kg; %BF:10.5 ± 5.22; SBP: 100.0 ± 11.5 mmHg; WC: 68.3 ± 6.4; DBP: 62.6 ± 6.6;
physical activity level: 41.1 ± 14.8) They underwent two 5-minute heart rate recordings for SB and metronome guided PB respectively. PB was adjusted from the respiratory rate during SB. Results from twoway repeated measures ANOVA revealed non-significant differences in the standard deviation of N-N
intervals (SDNN), low frequency (LF), peak LF (LFpeak), relative contribution of LF (%LF), LF normalized unit (LFnu), high frequency (HF), peak HF (HFpeak), relative contribution of HF (%HF), HF normalized unit (HFnu), total power (TP), LF to HF ratio (LF/HF), instantaneous beat to beat variability (SD1), continuous beat to beat variability (SD2), and SD1 to SD2 ratio (SD1/SD2). In conclusion, metronome guided PB adjusted from SB rate did not produce any significant difference in time, frequency and non-linear domains of HRV between asymptomatic obese and non-obese adolescents.
