Examining kidney blood flow response to exercise in African American adults

Neurovascular Control of Renal Blood Flow During Exercise in African American Adults

Not applicable Interventional University of Massachusetts, Boston · NCT03981640

This study is testing how exercise affects blood flow to the kidneys in healthy African American adults to see if it helps explain their higher risk for heart and kidney diseases.

What this trial studies

This study investigates how exercise affects kidney blood flow in healthy African American adults, who are at a higher risk for cardiovascular and renal diseases. It focuses on the sympathetic nervous system's response during physical exertion, cold stress, and mental stress. By understanding the renal vasoconstrictor response to these stressors, researchers aim to identify potential contributors to the increased incidence of cardiovascular and renal disease in this population. The study includes recreationally active participants who self-identify as African American or White and excludes those with certain health conditions.

Who should consider this trial

Good fit: Ideal candidates for this study are healthy, recreationally active African American adults who are fluent in English.

Not a fit: Patients with existing cardiovascular or renal diseases, hypertension, diabetes, obesity, or those who smoke may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better understanding and prevention strategies for cardiovascular and renal diseases in African American adults.

How similar studies have performed: While there is limited research on this specific population, studies have shown that understanding sympathetic nervous system responses can provide insights into cardiovascular risks, suggesting potential for success.
