Results:

• After walking for 20 minutes, children completed a test of cognition more accurately and had more intense neural activity than after sitting.
• In this study, participants performed better on achievement tests of reading comprehension but not spelling or arithmetic after participating in exercise compared with resting.

Methods:

• This study conducted cognitive tests after exercise among 20 preadolescent children. Children participated in 20 minutes of walking on a treadmill at 60% maximum heart rate. Results were compared to a resting session of cognitive testing followed by an aerobic fitness test among the same participants on separate days.
