Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Cerebral blood flow measured using ultrasound sonography during GXT (visit 1 and visit 2), calculating volumetric CBF during peak systolic and diastolic phases in the internal and external carotid artery, at baseline (V1) and at the end of the intervention (following 4 weeks of the intervention, V2) | — |
Secondary
| Measure | Time frame |
|---|---|
| Cardiac limitation measured using oxygen pulse (O2pulse, ml/beat), calculated by dividing oxygen uptake (V?O2, mL·min-1) by HR (bpm), which is an analogous estimate of stroke volume, at baseline (V1) and at the end of the intervention (following 4 weeks of the intervention, V2) | — |
