This study is looking at how brain blood flow and lactate (a substance produced by the body during exercise) respond to exercise in healthy adults. Researchers want to understand if there are differences in these responses between people who are not obese and those who are obese. The study will involve participants completing a maximum exercise test and a submaximal exercise test. The main goal is to measure brain blood flow during these 30-minute tests. They are currently looking for 24 healthy men and women between 18 and 45 years old, with a BMI between 18 and 40 kg/m2, who are not pregnant or breastfeeding and do not use nicotine.

Study design

This is an observational study with a planned enrollment of 24 participants. It compares brain blood flow and lactate response in obese and non-obese individuals.

What's involved

You would undergo a maximum exercise test and a submaximal exercise test. Brain blood flow will be measured over 30 minutes during these tests.

Compensation

Not stated in the trial record.

Follow-up

Brain blood flow will be measured over the 30 minutes of testing. Follow-up beyond this is not specified.
