Four groups of normotensive subjects were used in an experiment designed to: (a) replicate earlier data, (b) determine whether heart rate and respiration rate changes accompanied the development of acquired bi-directional diastolic blood pressure responses, and (c) investigate whether males and females acquired diastolic blood pressure responses at differential rates. Observations were carried out over one baseline and eight consecutive one-hour training sessions. Analyses of the blood pressure scores revealed subjects were able to acquire a bi-directional response, thereby confirming earlier reports. From subsequent analysis of the heart rate and respiration rate scores and from intercorrelations between diastolic blood pressure, heart rate, and respiration rate, no consistent relationships or patterns emerged. Comparisons of male and female blood pressure performance failed to yield evidence of reliable sex differences.
四组血压正常的受试者参与了一项实验，该实验旨在：(a) 复制早期数据；(b) 确定心率和呼吸频率的变化是否伴随后天获得的双向舒张压反应的发展；(c) 研究男性和女性获得舒张压反应的速率是否存在差异。观察在一个基线期和连续八个一小时的训练时段进行。对血压分数的分析表明，受试者能够获得双向反应，从而证实了早期报告。从随后对心率和呼吸频率分数的分析以及舒张压、心率和呼吸频率之间的相互关系来看，没有出现一致的关系或模式。男性和女性血压表现的比较未能得出可靠的性别差异证据。
