First, the title of their article implies that resting blood pressure was not significantly reduced with exercise training, when in fact it was (by -8/-6 mm Hg). Indeed, after 4 months of aerobic exercise training, their subjects' mean blood pressure had fallen to what most clinicians would consider a normal value (133/89 mm Hg).
