Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. EndoPAT measurements at baseline and immediately following the conclusion of the 12-week intervention. EndoPat is a non-invasive instrument used to measure endothelial function and vascular compliance. EndoPAT quantifies the endothelium-mediated changes in vascular tone, produced by a 5-minute occlusion of the brachial artery (using a standard blood pressure cuff). When the cuff is released, the surge of blood flow causes an endothelium-dependent flow mediated dilatation. The dilatation, manifested as Reactive Hyperemia, is captured by EndoPAT as an increase in the PAT Signal amplitude. A post-occlusion to pre-occlusion ratio is auto calculated by the EndoPAT software, providing the EndoPAT index. 2. ActivPAL measurements for 7 continuous days at baseline and following the 12-week study intervention. ActivPAL is a thigh worn accelerometer that provides quantification of free-living sedentary, upright and ambulatory activities | — |
