Summary

"This trial will measure blood flow in the brain during exercise using magnetic resonance imaging."

Who is the study for?
This trial is for healthy men and women aged 20-40 who exercise regularly, at least three times a week for 30 minutes. They should be familiar with using cardio exercise equipment but not have a high BMI, any major health issues like heart or kidney disease, or contraindications to MRI.
What is being tested?
The study measures how blood flows in the brain during exercise using an MRI. Participants will perform aerobic physical activities while their brain's blood flow responses are monitored.
What are the potential side effects?
Since the intervention involves only MRI scanning during exercise, there are no direct side effects from drugs or invasive procedures. However, MRIs can cause discomfort due to loud noises and confinement.
