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 . ) .
Effect of alternating postures on cognitive performance for healthy people performing sedentary work
Abstract Prolonged sitting is a risk factor for several diseases and the prevalence of worksite-based interventions such as sit-to-st and workstations is increasing . Although their impact on sedentary behaviour has been regularly investigated , the effect of working in alternating body postures on cognitive performance is unclear . To address this uncertainty , 45 students participated in a two-arm , r and omised controlled cross-over trial under laboratory conditions . Subjects executed vali date d cognitive tests ( working speed , reaction time , concentration performance ) either in sitting or alternating working postures on two separate days ( Clinical Trials.gov Identifier : NCT02863731 ) . MANOVA results showed no significant difference in cognitive performance between trials executed in alternating , st and ing or sitting postures . Perceived workload did not differ between sitting and alternating days . Repeated measures ANOVA revealed significant learning effects regarding concentration performance and working speed for both days . These results suggest that working posture did not affect cognitive performance in the short term . Practitioner Summary : Prior reports indicated health-related benefits based on alternated ( sit/st and ) body postures . Nevertheless , their effect on cognitive performance is unknown . This r and omised controlled trial showed that working in alternating body postures did not influence reaction time , concentration performance , working speed or workload perception in the short term
