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 . ) .
Acute effects on cognitive performance following bouts of standing and light-intensity physical activity in a simulated workplace environment.
OBJECTIVES To compare acute cognitive effects following bouts of st and ing ( ST AND ) , cycling ( CYCLE ) and walking ( WALK ) to a sit-only ( SIT ) condition . DESIGN R and omized cross-over full-factorial study . METHODS Nine overweight ( BMI = 29±3kg/m2 ) adults ( 30±15years ; 7 females , 2 males ) completed four conditions ( SIT , ST AND , WALK and CYCLE ) across a 6h period with a 7days washout period between conditions . SIT consisted of uninterrupted sitting . Experimental conditions included intermittent bouts of st and ing ( ST AND ) , cycling ( CYCLE ) and walking ( WALK ) . A cognitive performance battery ( Cogstate ) was completed twice in a seated position following bouts of st and ing and light-intensity physical activity . Mixed-effects models compared between-condition differences in st and ardized score ( z-score ) , accuracy ( % ) , and speed ( log10ms ) . RESULTS Cognitive performance z-score and accuracy measures were higher during ST AND , CYCLE and WALK ( P<0.05 ) conditions compared to the SIT condition . CYCLE was better than other experimental conditions . CONCLUSIONS Compared to uninterrupted sitting , short bouts of st and ing or light-intensity cycling and walking  may improve acute cognitive performance
