Conditioned diastolic blood pressure.
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.
