Evaluating Q-Collar Effects on Brain Blood Flow Control During Exercise (NCT06826781)
Evaluating Q-Collar Effects on Cerebrovascular Control in Response to Exercise
🩺 Plain-English Summary (8th-Grade Level)
The goal of this clinical trial is to learn how the FDA-cleared Q-Collar device affects brain blood flow regulation during rest and exercise in healthy adults. The main questions this study aims to answer are: 1. How does the Q-Collar affect brain blood flow when there are quick changes in blood pressure, like when standing up quickly, or when breathing against resistance? 2. How does the Q-Collar affect brain blood flow during exercise? Researchers will compare sessions where participants wear the Q-Collar to sessions where they do not wear the device to see if the Q-Collar improves brain blood flow during both rest and exercise. Participants will: * Complete two study visits, each 1 to 4 weeks apart. * Perform a series of tasks, including standing tests, breathing tests, and exercise on a stationary bike, while their heart rate, brain blood flow, and other body functions are monitored. * Wear the Q-Collar during one of the sessions and not wear it during the other session. The order of the sessions will be randomly assigned.
