The Effects of Mild Bilateral Jugular Vein Compression on Cerebrovascular Physiology

This project will investigate the effects of using the Q collar to apply gentle pressure to the jugular veins of the neck to monitor changes in brain (cerebrovascular) physiology during exercise and postural changes. Specifically we will investigate changes in brain blood flow velocity, relative changes in blood volume and oxygen levels, and changes in the space between the skull and the brain called the subarachnoid space. We will also monitor the heart and blood pressure. Following baseline resting data collection, postural changes will include lying down, sitting and standing. Then steady state exercise will be performed at a moderate-intensity for 30 minutes. All participants will perform these procedures with and without the Q collar on. This research will assist Q30 Sports Canada Inc. to validate the safety and efficacy of their collar device. TO BE CONT’D
