Cognitive function during low-intensity walking: a test of the treadmill workstation.

BACKGROUND The purpose of this study was to examine the effects of walking at self-selected speed on an active workstation on cognitive performance. METHODS Sixty-six participants (n = 27 males, 39 females; mean age = 21.06 ± 1.6 years) completed a treadmill-desk walking and a seated control condition, separated by 48 hours. During each condition, participants completed computerized versions of the Stroop test, a modified flanker task, and a test of reading comprehension. RESULTS No significant differences in response speed or accuracy were found between walking and sitting conditions for any the cognitive tests. CONCLUSIONS These findings reveal that performance on cognitive tasks, including executive control processes, are not impaired by walking on an active workstation. Implementing active workstations into offices and classrooms may help to decrease sedentariness without impairing task performance.
