Jogging Beats Walking for Older Adults

A new study suggests that jogging helps older adults maintain their muscular efficiency more so than walking.

Researchers at Humboldt State University and the University of Colorado, Boulder discovered the unexpected benefit of jogging in older adults by physiological testing adults while they exercised on a treadmill.

The study looked at adults over the age of 65 — some of whom walk for exercise and some who run for exercise. The researchers found that those who run at least 30 minutes, three times a week were less likely to experience age-related physical decline in walking efficiency than those who simply walked.

In fact, the older runners were seven to 10 percent more efficient at walking than those who didn’t jog.

The paper is published online in the journal PLOS ONE.

“What we found is that older adults who regularly participate in high aerobic activities — running in particular — have what we call a lower metabolic cost of walking than older, sedentary adults. In fact, their metabolic cost of walking is similar to young adults in their 20s,” said Justus Ortega, Ph.D., a kinesiology professor at Humboldt State.

Metabolic cost is the amount of energy needed to move and naturally increases as we age. High metabolic cost contributes to making walking more difficult and tiring. Decline in walking ability is a key predictor of morbidity in older adults.

In the study, researchers looked at self-reported older joggers over the age of 65 — those who ran at least 30 minutes a day, three times a week — and self-reported walkers, those who walked three times a week for 30 minutes.

Participants were asked to walk on a treadmill at three speeds (1.6, 2.8, and 3.9 miles per hour) as researchers measured their oxygen consumption and carbon dioxide production.

Researchers aren’t yet sure what makes joggers more efficient than walkers but they believe it may have something to do with the mitochondria found in cells.

Evidence suggests that people who exercise vigorously have healthier mitochondria in their muscles.

“The bottom line is that running keeps you younger, at least in terms of efficiency,” said Rodger Kram, Ph.D., a professor at the University of Colorado, Boulder, and a co-author of the paper.

Future studies are planned to examine whether other highly aerobic activities — such as swimming and cycling — also mitigate age-related physical decline.
