Diastolic and systolic blood pressure changes were of broadly similar magnitude and direction within groups except for subjects exposed to urban scenes. For urban pleasant Scenes, average systolic blood pressure fell whilst diastolic rose, whereas for urban unpleasant scenes the opposite occurred (Figures 2 and 3). Thus there was no net change in mean arterial blood pressure for groups exposed to urban scenes (Figure 1). When blood pressure effects were Expressed as a percentage change from per – exercise levels there was a statistically significant effect of picture category (one way ANOVA) on systolic blood pressure (p < 0.01), and mean blood pressure (p < 0.05) but not on diastolic blood pressure. Post hoc Tukey tests showed that the significant differences in percentage change in
