Abstract
Background: Dietary calcium intake and the renin angiotensin system (RAS) regulate blood pressure (BP) by modulating calcium homeostasis. Despite similar BP regulatory effects, the influence of dietary calcium intake alone and combined with RAS polymorphisms on the BP response following acute aerobic exercise (i.e., postexercise hypotension) has not been studied. Thus, we examined the effect of dietary calcium intake and selected RAS polymorphisms on postexercise hypotension.
Methods: Subjects were men (n = 50, 43.8 [+ or -] 1.3 yr) with high BP (145.3 [+ or -] 1.5/85.9 [+ or -] 1.1 mm Hg). They completed three experiments: non-exercise control ...
