Sedentary Time, Physical Activity, and Executive Function in a Longitudinal Study of Youth

Abstract

Childhood sedentary time and PA may affect executive function at 15 years; however, prospective studies are needed to examine the concurrent change in both sedentary time and PA with executive function.

Moving fast, thinking fast: The relations of physical activity levels and bouts to neuroelectric indices of inhibitory control in preadolescents

“…We found that greater engagement in daily MPA was related to poorer response accuracy on congruent trials in uncorrected analyses. Two previous studies assessed daily MPA in relation to inhibitory control and reported both negative 17 and positive associations 14 . However, due to the differences in cognitive measures 14 , 17 and accelerometer cut-points, 14 our studies are not directly comparable.…”

“…Likewise, daily MVPA was generally not related to cognitive control. Previous studies on objectively measured daily PA and cognitive control focused primarily on MVPA and reported mixed findings 12, 13, 14, 15, 16, 17, 18 , 81 . When it was included in the analyses, daily VPA was not related to selective attention 14 or impulse control 17 in adolescents.…”

However, the differences in the age of the samples at the time of cognitive assessment,14, 17 study design, 17 and cognitive measures 17 preclude meaningful comparisons between our study and these previous studies. For example, in our study we included preadolescents whose inhibitory control is still dynamically developing; while smaller gains in inhibitory control have been observed in adolescents 71 .…”

“…However, cross-sectional research examining associations between objectively measured daily MVPA and cognitive control in children and adolescents has yielded equivocal findings. Specifically, positive,12, 13, 14 null, 13 , 15, 16, 17, 18 and negative 17 associations with cognitive control have been reported. One reason for these discrepant findings may be related to the fact that a minimum PA dose is potentially required for the cognitive benefits to emerge.…”
