There are multiple benefits of physical activity, such as weight maintenance and overall lower rates of morbidity and mortality; however, individuals with sedentary desk-bound jobs may not receive these health benefits due to less time for physical activity. Consequently, an increasing trend in the workplace is for employees to walk on treadmills while working. Although job-related treadmill walking has known health benefits, such as decreasing back pain, alleviating stress, and reducing weight gain, the effect of treadmill walking on cognitive performance is not well known and may affect employee productivity. Our objective was to determine if there are significant behavioral differences in response inhibition (the ability to withhold an overt response) and conflict-related interference between participants walking on a treadmill and sitting controls. Seventy-six neurologically and psychologically healthy individuals were randomly assigned to sitting (n = 39; 17 female) or treadmill walking (n = 37; 23 female) conditions. Participants did not differ significantly in body mass index or overall fitness levels (ps > .20). All participants completed a computerized Go/No-Go and a computerized Eriksen Flanker task. Accuracy and response time data were analyzed using repeated measures analysis of variance (ANOVA). Results indicated that there were no significant between-groups differences for individuals walking on a treadmill versus sitting on indices of response inhibition and conflict-related interference (ps > .24). The results suggest that walking on a treadmill does not decrease efficiency in these cognitive tasks and may not impact workplace performance.
