Participant characteristics and baseline hemodynamics
| Characteristic | Study 1 | Study 2 |
|---|---|---|
| Sex (men/women) | 9/1 | 7/6 |
| Age, yr | 29 ± 4 | 28 ± 5 |
| Height, cm | 176.6 ± 7.5 | 174.5 ± 9.8 |
| Weight, kg | 77.1 ± 12.4 | 70.4 ± 12.5 |
| BMI, kg/m2 | 24 ± 4 | 23 ± 3 |
| Systolic BP, seated, mmHg | - | 108 ± 10 |
| Diastolic BP, seated, mmHg | - | 67 ± 9 |
| MAP, mmHg | - | 94 ± 9 |
| HR, beats/min | - | 57 ± 9 |
| SV, ml/beat | - | 89 ± 21 |

Values are means ± SD. BMI, body mass index; BP, blood pressure; MAP, mean arterial pressure; HR, heart rate; SV, stroke volume; CO, cardiac output. Study 1: values of validation protocol; hemodynamics not measured. Study 2: values of middle cerebral artery protocol.
