Conditioned pain modulation among young, healthy, and physically active African American and non-Hispanic White adults.

Objective: Research shows that African American (AA) adults experience more severe and frequent pain compared to non-Hispanic White (NHW) adults. Additionally, experimental studies demonstrate that AA adults exhibit less efficient central pain inhibition compared to NHW adults, which may partially explain the racial/ethnic disparities in pain. Evidence suggests that regular physical activity (PA) may help improve central pain inhibition, but research shows that AA adults engage in less PA, and are less likely to meet PA guidelines for health promotion compared to NHW adults.
