The purpose of this study is to examine the effects of differing levels of dietary sodium on cardiovascular responses to stress in white normotensive subjects aged 18-28 and 55-70 years old. This will determine whether subjects at risk for hypertension (i.e. older males) exhibit augmented vascular reactivity to a vasoconstrictive stimulus during sodium loading.

本研究的目的是检查不同水平的 钠对白色血压正常人心血管应激反应的影响 受试者年龄为18-28岁和55-70岁。 这将决定是否 具有高血压风险的受试者（即老年男性）表现出增强的 在钠负荷期间血管对血管收缩刺激的反应性。
