A study has shown that regularly walking a dog boosts levels of physical activity in older people, especially during the winter.
Published in the Journal of Epidemiology and Community Health, the study used data from the EPIC Norfolk cohort study, which is tracking the health and wellbeing of thousands of residents of the English county of Norfolk.
The researchers from the University of East Anglia (UEA) and Centre for Diet and Activity Research (CEDAR) at the University of Cambridge found that owning or walking a dog was one of the most effective ways to beat the usual decline in later-life activity, even combatting the effects of bad weather.
More than 3,000 older-adults participating in the study were asked if they owned a dog and if they walked one. They also wore an accelerometer, a small electronic device that constantly measured their physical activity level over a seven-day period.
Dog owners were sedentary for 30 minutes less per day, on average.
Because bad weather and short days are known to be barriers to staying active outdoors, the researchers linked this data to the weather conditions experienced, and sunrise and sunset times on each day of the study.
“We know that physical activity levels decline as we age, but we’re less sure about the most effective things we can do to help people maintain their activity as they get older,” said lead author of the paper, Dr Yu-Tzu Wu. “We found that dog walkers were much more physically active and spent less time sitting overall.”
Wu added that, when researchers looked at how the amount of physical activity participants undertook each day varied by weather conditions, they were quite were surprised at the difference between those who walked dogs and the rest of the participants in the study. The team found that on shorter days and those that were colder and wetter, all participants tended to be less physically active and spent more time sitting. Yet dog walkers were much less impacted by these poor conditions.
“We were amazed to find that dog walkers were on average more physically active and spent less time sitting on the coldest, wettest, and darkest days than non-dog owners were on long, sunny, and warm summer days,” project lead Prof Andy Jones said.
The researchers caution against recommending everyone owning a dog, as not everyone is able to look after a pet. But, they suggest these findings point to new directions for programmes to support activity.
“Physical activity interventions typically try and support people to be active by focussing on the benefits to themselves, but dog walking is also driven by the needs of the animal,” Jones said. “Being driven by something other than our own needs might be a really potent motivator and we need to find ways of tapping into it when designing exercise interventions in the future.”
