Abstract

A dog owner (female, 37 years) wore an activPALTM monitor [2] for 7 days, and completed a diary reporting timing of walking outdoors (with/without the dog). ActivPALTM monitors classify acceleration into periods of sitting, standing or walking allowing outcome measures relating to the quantity, quality and patterning of PA, e.g. walking at a pace suitable for health. Walking events (continuous periods of walking) were coded into activity categories based on diary information. Duration of walking, number of steps, and mean cadence of walking events were compared across categories.

Results
On average the participant walked 2.3 hours/day, taking 12,118 steps/day, and walked the dog once/day. Mean walking event duration (72 vs. 33 s) and steps taken (127 vs. 54) were consistently higher when walking outdoors with the dog than without the dog. Cadence, however, was only marginally higher during dog walking (87 vs. 82 steps/min).

Conclusion
Clear differences were demonstrated in the accumulation of outdoor walking with and without the dog. This level of detail in the pattern of walking allows interpretation of whether the walking could be health enhancing. Furthermore, this methodology will allow differences in health enhancing PA between dog owners and non-dog owners to be investigated in future studies.
