Chronic aerobic exercise improves blood pressure dipping status in African American nondippers.

Objective The effects of exercise training on nocturnal blood pressure (BP) dipping status remain unclear. African Americans have the highest prevalence of non-dippers compared to other racial/ethnic populations. In this 6-month study we tested the hypothesis that long-term aerobic exercise training would increase the levels of nocturnal BP dipping in African American non-dippers.
