It turns out that seniors who walk faster on a treadmill test live longer, on average, than slower walkers.
Geriatricians at the University of Pittsburgh tracked a group of seniors for 10 years and found those who covered the equivalent of 2-1/2 miles per hour on a treadmill outlived walkers able to walk less than 1-1/2 miles per hour.
The researchers adjusted for sex, race, age, chronic illness and hospitalization and found that walking speed appeared to be an independent predictor of longevity.
Should this surprise us? I don't think so. It confirms what those living a fitness lifestyle know intuitively.
