Understanding the contribution that attending a workplace has in accumulating physical activity (PA) may help inform strategies used to increase PA. This study explores the influence that attending work has on the total number of steps taken and the time spent in moderate to vigorous activity (MVPA). A global position system (GPS) was used to identify the geographical domain of the participant. An activity monitor (activPAL, PALtechnologies Ltd, Glasgow, UK) was employed to measure the number of steps taken and the cadence of those steps. Both devices were worn for seven consectutive days and 5 work days extracted post data collection. The data from the two devices were synchronised allowing domain, volume and intensity of PA to be explored. The distance from the home domain to the workplace was used to establish if there was any relationship between commute distance and number of steps accumulated and time in MVPA.
Twenty-six office workers (17F; mean age 38 (range 23-65)) were recruited. The number of steps taken per day on average for the group was 11 008 (SD +/- 2999) with time spent in MVPA per day being 32.7 (SD +/- 17.1) min. The commute accounted for 32% or 3550 (SD +/- 1664) of the steps taken and 68% or 22.0 (SD +/- 14.1) min of MVPA. No statistically significant correlations with distance from home to the workplace for either variable were found.
This work explores the contribution that attending work makes to PA, combining data from a GPS system and an objective activity monitor. The commute to works accounts for more than two-thirds of the MVPA accumulated per day. This provides meaningful in sight into the volume and intensity of individuals' activity and also its context.
