Baroreflex sensitivity and blood pressure variability (n = 7) during the repeated squat-stand maneuver for prior exercise only vs. the repeat assessment (no external stressors present).
| Parameter | Exercise Only | Repeat | t-statistic | Cohen's D | p-value |
|---|---|---|---|---|---|
| BRS-down (msec/mmHg) | 7 ± 4 | 5 ± 2 | 1.8 | 0.68 | 0.12 |
| BRS-up* (msec/mmHg) | 14 ± 4 | 9 ± 4 | 5 | 1.89 | <0.01 |
| BRS-pooled* (msec/mmHg) | 9 ± 4 | 6 ± 3 | 2.5 | 0.94 | 0.04 |
| HF-BPV (mmHg2) | 36 ± 18 | 39 ± 15 | −0.4 | −0.15 | 0.69 |
| LF-BPV (mmHg2) | 1154 ± 572 | 1260 ± 569 | −0.4 | −0.15 | 0.69 |
| TP-BPV (mmHg2) | 1214 ± 594 | 1319 ± 580 | −0.4 | −0.15 | 0.71 |
* (p < 0.05).
HF = high frequency; LF = low frequency; TP = total power; BRS = spontaneous baroreflex sensitivity, BPV = systolic blood pressure variability.
