Main physiological parameters averaged during sitting and standing at rest and during the squat-stand maneuver.
| Parameter | Sitting | Standing | SSM | p-value |
|---|---|---|---|---|
| MAP (mmHg) | 89.4 ± 10.8 | 89.4 ± 11.4 | 97.8 ± 14.2 | <0.0001 |
| Psys (mmHg) | 122.0 ± 16.5 | 118.0 ± 15.9 | 136.2 ± 24.8 | <0.0001 |
| Pdias (mmHg) | 76.2 ± 9.9 | 78.2 ± 10.9 | 81.9 ± 11.5 | 0.024 |
| MCAv-R (cm/s) | 60.5 ± 12.3 | 56.5 ± 12.4 | 63.4 ± 13.4 | <0.0001 |
| MCAv-L (cm/s) | 57.6 ± 11.9 | 53.9 ± 12.0 | 60.6 ± 11.9 | <0.0001 |
| EtCO2 (mmHg) | 37.8 ± 3.1 | 35.7 ± 3.3 | 39.8 ± 4.0 | <0.0001 |
| HR (bpm) | 73.2 ± 11.2 | 84.4 ± 12.2 | 93.6 ± 11.8 | <0.0001 |
Values are mean ± SD. MAP: mean arterial blood pressure; Psys: systolic blood pressure; Pdias: diastolic blood pressure; MCAv-R: middle cerebral artery velocity, right hemisphere; MCAv-L: left hemisphere; EtCO2: end-tidal CO2: HR, heart rate; bpm: beats per minute.
