Table 2.
Descriptive statistics—mean (SD)—of frequency-domain HRV features and related Univariate Statistical Analysis results (p-values).
| Measures | Descriptive statistics | Condition effect | Pairwise comparisons | ||||
|---|---|---|---|---|---|---|---|
| FB | NPBH | HPBH | FB vs. NPBH | FB vs. HPBH | NPBH vs. HPBH | ||
| VLF | 2400 (2100) | 1700 (1900) | 2500 (5100) | NS | NS | NS | NS |
| LF | 3000 (2300) | 1500 (1600) | 3300 (3000) | NS | NS | NS | NS |
| HF | 650 (500) | 220 (200) | 2100 (3400) | 0.00 | 0.01 | NS | 0.00 |
| LF/HF | 5.9 (6.3) | 10.2 (9.2) | 4.8 (5.9) | 0.03 | NS | NS | 0.01 |
All the frequency power values are expressed in mV2/Hz. NS stands for not significant at p-value ≥0.05. All the abbreviations are described in the text.
