View larger version (21K): [in a new window]   Figure 1 Levels of systolic blood pressure (SBP), diastolic blood pressure (DBP) and mean blood pressure (MBP) at baseline and for up to 90 min after a 45-min period of low-intensity exercise (50% peak oxygen uptake) in elderly normotensive control subjects open circles and elderly hypertensive patients closed circles. Note that exercise provoked a postexercise reduction in blood pressure in hypertensive patients, but not in normotensive control subjects. *p < 0.05 for intragroup comparisons vs. baseline; +p < 0.05 for intergroup comparisons.

Note that blood pressure during 22 h, at daytime and nighttime, on the exercise day was significantly (p < 0.05) decreased in HT, but not in NC. *p < 0.05 for intragroup comparisons.
