Table 3.
Baroreflex sensitivity and blood pressure variability (n = 14) during the repeated squat-stand maneuver for the contraindicated assessment (one or more external stressors present) vs. the repeat assessment (no external stressors present).
| Parameter | Contraindicated | Repeat | t-statistic | Cohen's D | p-value |
|---|---|---|---|---|---|
| BRS-down (msec/mmHg) | 5 ± 2 | 6 ± 3 | 0.60 | 0.16 | 0.60 |
| BRS-up* (msec/mmHg) | 8 ± 4 | 11 ± 5 | 2.97 | 0.79 | 0.01 |
| BRS-pooled (msec/mmHg) | 6 ± 3 | 8 ± 3 | 1.67 | 0.45 | 0.12 |
| HF-BPV (mmHg2) | 44 ± 18 | 40 ± 15 | −0.72 | −0.19 | 0.49 |
| LF-BPV (mmHg2) | 1259 ± 485 | 1361 ± 624 | 0.59 | 0.16 | 0.56 |
| TP-BPV (mmHg2) | 1329 ± 496 | 1428 ± 643 | 0.55 | 0.15 | 0.59 |
* (p < 0.05).
HF = high frequency; LF = low frequency; TP = total power; BRS = spontaneous baroreflex sensitivity, BPV = systolic blood pressure variability.
