Youre ONLY AS OLD AS YOUR ARTERIES. To keep your blood vessels flexible, you need AEROBIC exercise. If Dr. Michael Joyner of the Mayo Clinic & Doug Seals, PhD of the University of Colorado cant convince you to get up & exercise---I GIVE UP!! Do you want flexible arteries or not? Just read this weeks Runners World article (by Alex Hutchinson) all about the bennies of FLEXIBLE ARTERIES that come from aerobic (not resistance) exercise. Yes, I know that lots of leafy greens, beets, & plants are wonderful for arteries--but, who says you cant do both? (Thanks to Tom A.) Kick it up a giant notch, with exercise, too! There are piles of evidence demonstrating how AEROBIC EXERCISE improves the way our blood vessels work: their compliance (how flexible/stiff they are) and their endothelial function (how well the inner lining of your blood vessels responds to changing needs by dilating and contracting, for example). And if you still need more evidence--read Doug Seals hot-off-the-press article & Michael Joyners editorial in the Journal of Applied Physiology. 1.

Adolph Lecture, by Douglas Seals of the University of Colorado, which has just been published in the Journal of Applied Physiology (along with an accompanying editorial by Joyner). Theres a growing pile of evidence that (a) vessel function is extremely important for things like maintaining heart rate variability and avoiding arrhythmias, and (b) exercise is an extremely powerful way of preserving vessel function as you age. As Joyner points out (in his JAP editorial), masters athletes provide a perfect real-world laboratory to observe what might be described as aging in the absence of physical inactivity (a relatively rare phenomenon in developed countries these days): For many organ systems comparison studies between younger and older athletes can shed light on minimal rates of aging. For example the age-related decline in peak heart rate is only minimally affected by lifelong training (12). By contrast, vascular function [i.e. how well your blood vessels work] is largely preserved (5,10,11). These studies help solve the problem that aging is frequently studied in the context of one or more co-existing diseases that are associated with aging but by no means an obligatory part of it.
