Walking fast can live longer

Move is a sign of vitality

A new study published by the Journal of the American Medical Association, the walking speed can be a good indicator of the longevity of an elderly person.

Professor Stephanie Studenski, University of Pittsburgh, who compiled the results of nine previous studies from 1986 to 2000 and involving nearly 35,000 people aged 65 and over, claims to be "able to demonstrate that the ability a person to move strongly reflects the vitality and health. "

The team found that it was possible to calculate a survival rate of almost exactly 10 years just by taking into account the rate of speed of walking for seniors. Those who have a life expectancy average walked 0.8 meters per second, while those who walked more than 1 meter per second seemed to live longer.

The researchers note that the prediction of longevity based on walking speed becomes progressively more accurate as the observed subject has passed the milestone of 75 years. "Walking requires energy, motion control, support and requirements for systems of several organs including the heart, lungs, circulatory, nervous, musculo-skeletal disorders. Slowing the march may reflect both damaged systems and a high energy cost of walking, "says research by the team at the University of Pittsburgh.

"This is a real part of human experience to see that when someone slows with age, he has lost some of its ability to do as well as in the past," said Dr. Studenski.
