Abstract

Physical activity (PA) is established as a cornerstone of cardiovascular health, however, disparities in participation exist across sociocultural groups, which in turn affect cardiovascular outcomes. Evidence suggests that although the positive cardiovascular effects of exercise are consistent across populations, notable differences in the magnitude of these benefits exist for racial and ethnic minorities and the female sex. Women derive greater protection from PA compared with men, with reduced rates of sudden cardiac death. In this review we examine the complex interplay of race and/or ethnicity and sex on the cardiovascular benefits associated with PA and exercise, cardiovascular adaptations to exercise, risks of sudden cardiac death, and "excessive" volume of exercise. Understanding these factors is crucial for developing targeted interventions to promote cardiovascular health and offset disparities.
