First-time marathon runners rewind the clock on vascular aging

Key clinical point: Individuals who trained for a marathon showed improvement in age-related aortic stiffness and reduction in blood pressure.

Major finding: Compared with pretraining values, the descending aortas of marathon completers were 9% more distensible at the level of the bifurcation of the pulmonary artery and 16% more distensible at the level of the diaphragm (P = .0009 and .002, respectively).

Study details: A prospective cohort study of 138 first-time completers of the London Marathon.
