Can Touching Your Toes Test Your Arteries?

Phys Ed: Can Touching Your Toes Test Your Arteries?
By GRETCHEN REYNOLDS
A provocative new study published this year in the journal Heart and Circulatory Physiology suggests, however, that there may be a novel way to test at least one element of your heart's health right in your own living room, right in the middle of the holidays. Sit on the floor with your legs stretched straight out in front of you, toes pointing up. Reach forward from the hips. Are you flexible enough to touch your toes? If so, then your cardiac arteries probably are also flexible.
What is surprising are some early indications that increasing your flexibility might somehow loosen up your arteries, too. That was the accidental and, as yet unreplicated finding of a small 2008 study at the University of Texas at Austin. The study was designed to examine whether weight lifting increased arterial stiffness. (It didn't, at least on this occasion.) The control group consisted of people who stretched. They were not expected to show any change in cardiac function, but over the course of 13 weeks they in fact increased the pliability of their arteries by more than 20 percent.
