Effects of hot head-out water immersion on cerebral hemodynamics
The purpose of this study is to examine the effects of hot and ambient water immersion on 1) resting brain blood flow and 2) the brain blood flow response to decreases and increases in carbon dioxide in the blood. There will be 3 visits at UB South Campus: an informed consent/screening visit (30-60 minutes) and two experimental visits (5 hours each) at least 7 days apart. You will be seated in a pool with water up to your neck and your arms will be immersed in the water. Prior to, during, and after the water immersion, we will obtain a venous blood sample and you will complete a breathing test to measure your brain blood flow.
(CSR 210538148997) Adequate blood flow and oygen delivery to the brain is critical for normal physiologic function and survival. Certain populations (e.g., older adults, concussion, sedentary) are at risk of eperiencing reductions in cerebral blood flow and cerebral vascular function that may increase their risk of stroke and/or dementia. Currently, eercise is the primary modality to improve brain
