Neural Control of Kidney Blood Flow During Exercise in African American Adults

The goal of this clinical trials is to learn if healthy young African American (AA) adults have a larger change in their kidney blood flow during exercise compared to White (W) adults. The main questions that this study aims to answer are: * Do healthy young AA adults have a larger decrease in kidney blood flow during exercise compared to W adults? * Do healthy young AA adults have a larger decrease in kidney blood flow during other types of stress compared to W adults? During two visits in the research lab, participants will: * Perform a fitness test * Perform cycling exercise while lying down * Undergo a cold hand test * Perform a mental math test Completing this clinical trial will help researchers to understand more about why many AA adults have heart and kidney problems, so future research can study ways to reduce the number of AA adults who have these health issues.
