Study: Faster walkers may live longer
Los Angeles Times, July 23, 2009
Walking is a terrific and convenient form of exercise, especially as people get older. But is a leisurely stroll as good as a fast clip? A recent study measuring walking speed and longevity says maybe not, at least when it comes to life expectancy.
In a presentation at the IAGG World Congress of Gerontology and Geriatrics this month in Paris, researchers analyzed nine previous studies that included 34,000 men and women whose average age was almost 74.
Overall, faster walkers lived longer than slower walkers, with those walking at a gait speed of 1.4 meters a second or faster more than twice as likely to be alive after 10 years than those who walked at 0.4 meters a second or slower.
