The relationships of coffee consumption habits and cardiovascular tonus at rest and in response to an orthostatic and an ergometric challenge were determined in 338 nonsmoking women. Habitual coffee consumption was unrelated to blood pressure. Coffee consumption on the test day was associated with slightly higher systolic blood pressure at rest and with smaller increases due to ergometer cycling. The latter was confirmed by a similar relation with saliva caffeine concentrations measured in a subsample (n = 200). These findings are discussed in terms of a transient stabilising effect of caffeine on blood pressure.
在338名不吸烟女性中，研究了咖啡饮用习惯与静息状态以及体位改变和运动负荷试验时心血管张力之间的关系。习惯性咖啡饮用与血压无关。试验当天饮用咖啡与静息时略高的收缩压相关，且因测力计骑行导致的血压升高幅度较小。在一个子样本（n = 200）中测量的唾液咖啡因浓度与上述结果存在类似关系，证实了后者。从咖啡因对血压的短暂稳定作用方面对这些发现进行了讨论。
