本实验研究了两种实验室应激(无信号电击回避反应时间和冷加压任务)对年轻成年女性月经周期卵泡期和黄体期心血管反应的影响。一组男性受试者也接受了测试，这些受试者的高血压家族史和压力与休息之间的时间匹配。结果显示，与黄体期或男性相比，处于卵泡期的女性对反应时间任务(心率和血压)的心血管反应性降低。心血管对这一任务的高反应性以前与高血压家族史有关。在冷加压试验中没有观察到差异变化。这些结果从荷尔蒙对血压调节的可能影响，以及评估女性应激反应的方法学考虑方面进行了讨论。
An experiment was conducted to study the effects of 2 laboratory stresses (unsignaled shock-avoidance reaction time and cold pressor tasks) on cardiovascular responses of young adult women during the follicular or the luteal phases of the menstrual cycle. A comparison group of male subjects, matched for family history of hypertension and for time between stress and rest sessions, was also tested. Results showed reduced cardiovascular responsiveness to the reaction time task (heart rate and blood pressure) for the women in the follicular phase of their cycle as compared with those in the luteal phase or with the males. Cardiovascular hyperresponsivity to this task has been previously related to familial history of hypertension. No differential changes were observed during the cold pressor test. These results are discussed in terms of possible hormonal effects on blood pressure regulation, and with respect to methodological considerations for assessing stress reactivity among women.
