Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The research aims are:
1. To determine if a single bout of aerobic exercise acutely enhances cerebrovascular function
2. To determine the effect of aerobic exercise intensity and dose on cerebrovascular function in healthy adults.
3. To determine if the acute exercise-induced changes in cerebrovascular function are associated with acute exercise-induced changes in peripheral vascular function in healthy adults.
