Mild walking contributes to improved overall health, maintaining healthy weight, strengthening bones, and lifting mood. As such, there is now an attraction to treadmill desk stations in replacement of traditional desks, allowing individuals to walk while performing office work. However, there is little research determining if treadmill walking would affect attention and working memory abilities. We aimed to determine how working memory and attention would be affected while walking on a treadmill. METHOD: Participants included seventy-six healthy individuals assigned to sitting (n = 39; 17 female) or treadmill walking (n = 37; 23 female) conditions. Participants completed the Paced Auditory Serial Attention Task (PASAT) as a measure of attention and working memory while either walking or sitting. Data were analyzed using repeated measures analysis of variance (ANOVA). RESULTS: A Group x Time ANOVA on PASAT errors showed a main effect of group (p = .03), with those in the treadmill group committing significantly more errors than those in the sitting group on trials two (2.0 seconds) and four (1.2 seconds; ps < .03). The Group x Time interaction overall, however, was not significant (p = .26) as both groups significantly made more errors as the PASAT speed increased (p < .001). DISCUSSION: There were significant overall differences in PASAT performance between participants in sitting and walking groups. Findings suggest treadmill walking may facilitate decreased ability to hold in mind and rapidly process information. Thus, although treadmill desks may have health benefits, performance on speeded and complex attention tasks may be impacted.
