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 . ) .
Active Workstations Do Not Impair Executive Function in Young and Middle-Age Adults
Purpose This study aim ed to examine the effects of self-selected low-intensity walking on an active workstation on executive functions ( EF ) in young and middle-age adults . Methods Using a within-subjects design , 32 young ( 20.6 ± 2.0 yr ) and 26 middle-age ( 45.6 ± 11.8 yr ) adults performed low-intensity treadmill walking and seated control conditions in r and omized order on separate days , while completing an EF test battery . EF was assessed using modified versions of the Stroop ( inhibition ) , Sternberg ( working memory ) , Wisconsin Card Sorting ( cognitive flexibility ) , and Tower of London ( global EF ) cognitive tasks  . Behavioral performance outcomes were assessed using composite task z-scores and traditional measures of reaction time and accuracy . Average HR and step count were also measured throughout . Results The expected task difficulty effects were found for reaction time and accuracy . No significant main effects or interactions as a function of treadmill walking were found for tasks assessing global EF and the three individual EF domains . Accuracy on the Tower of London task was slightly impaired during slow treadmill walking for both age-groups . Middle-age adults displayed longer planning times for more difficult conditions of the Tower of London during walking compared with sitting . A 50-min session of low-intensity treadmill walking on an active workstation result ed in accruing approximately 4500 steps . Conclusions These findings suggest that executive function performance remains relatively unaffected while walking on an active workstation , further supporting the use of treadmill workstations as an effective approach to increase physical activity and reduce sedentary time in the workplace
