Effects of menstrual cycle phase on physiological levels and reactivity were studied in a within-subject design with 20 women aged 18-30 years. Basal body temperature was monitored daily; follicular and luteal recording sessions occurred before and after the ovulatory temperature rise, respectively. The design consisted of task and rest periods, presented in counterbalanced order across phases. Half the subjects began during their follicular phase and half began during their luteal phase. Follicular and luteal phases were compared for differences between baseline resting levels, as well as for reactivity. The results showed menstrual phase differences in heart rate, pulse transit time, and EEG alpha, particularly during tasks, but no difference in reactivity. Habituation effects in the group that began during the follicular phase often masked luteal activation. In spite of the fact that not all statistical results achieved significance, the consistency of most trends supports the conclusion that physiological recording sessions with women might best be restricted to the follicular phase.
采用受试者内设计，对20名年龄在18至30岁之间的女性进行了月经周期阶段对生理水平和反应性影响的研究。每天监测基础体温；卵泡期和黄体期记录分别在排卵体温升高之前和之后进行。该设计包括任务期和休息期，各阶段以平衡顺序呈现。一半受试者在卵泡期开始，另一半在黄体期开始。比较卵泡期和黄体期在基线静息水平以及反应性方面的差异。结果显示，心率、脉搏传输时间和脑电图α波存在月经周期阶段差异，尤其是在任务期间，但反应性无差异。卵泡期开始的组中的习惯化效应常常掩盖了黄体期的激活。尽管并非所有统计结果都具有显著性，但大多数趋势的一致性支持这样的结论，即对女性进行生理记录可能最好限制在卵泡期。
