Conclusion : These data suggest that sedentary behavior is not associated with changes in cognitive performance in interventions that intend to reduce sedentary behavior .
Background : It is now well-established that sedentarity has a negative impact on the physiological functioning and health of humans , whereas very little is known about the psychological repercussions , especially in cognitive functioning .
Yet , study ing the cognitive effects of the sedentary lifestyle is particularly relevant in the short term for productivity and in the long term for cognitive health ( accelerated aging ) .
This systematic review therefore aims to make an inventory of the potential cognitive effects of sedentarity at the workplace .
Methods : Pubmed , PsycINFO , Cochrane , Web of Science , and Scopus were search ed for English- language peer- review ed articles published between January 1 , 2000 and December 31 , 2017 to identify studies including sedentary behavior  and objective measures from cognitive domains ( cognitive inhibition , cognitive flexibility , working memory , etc . ) .
Effects of a Sedentary Intervention on Cognitive Function
Purpose : To examine the effects of a free-living , sedentary-inducing intervention on cognitive function . Design : R and omized controlled , parallel group intervention . Setting : University campus . Participants : Thirty-three young adults ( n = 23 intervention ; n = 10 control ) . Measures : The intervention group was asked to eliminate all exercise and minimize steps to ≤5000 steps/day for 1 week , whereas the control group was asked to continue normal physical activity ( PA ) levels for 1 week . Both groups completed a series of  8 cognitive function assessment s ( assessing multiple parameters of cognition )  preintervention and immediately postintervention . The intervention group was asked to resume normal PA levels for 1 week postintervention and completed the cognitive assessment s for a third time at 2 weeks postintervention . Analysis : Split-plot repeated- measures analysis of variance . Results : The results of our statistical analyses showed that the group × time interaction effect was not significant ( P > .05 ) for any of the evaluated cognitive parameters . Conclusion : These findings demonstrate the need for future experimental investigations of sedentary behavior to better underst and its effects on cognitive function . However , although previous work has demonstrated favorable effects of acute and chronic PA on cognitive function , our findings suggest that a 1-week period of reduced PA does not detrimentally affect cognitive function , which may have encouraging implication s for individuals going through a temporary relapse in PA
