Overall , we found data that support a negative relationship between obesity and various aspects of neurocognitive functioning , such as executive functioning , attention , visuo-spatial performance , and motor skill .
The existing literature is mixed on the effects among obesity , general cognitive functioning , language , learning , memory , and academic achievement .
Executive dysfunction is associated with obesity-related behaviors , such as increased intake , disinhibited eating , and less physical activity .
Physical activity is positively linked with motor skill .
Childhood obesity rates have risen dramatically over the past few decades .
Although obesity has been linked to poorer neurocognitive functioning in adults , much less is known about this relationship in children and adolescents .
Therefore , we conducted a systematic review to examine the relationship between obesity and obesity-related behaviors with neurocognitive functioning in youth .
FIT Kids: Time in target heart zone and cognitive performance.
OBJECTIVE This present study examined time spent in the target heart zone ( THZ ) and its relationship to tasks requiring variable amounts of executive control function in prepubescent children participating in a 9-month r and omized controlled physical activity program .  METHODS A sample of 59 participants performed the Stroop Color-Word Test and the Comprehensive Trail Making Test cognitive assessment s.  Heart rate data were collected during participation in the physical activity program using E600 heart rate monitors ( Polar , Finl and ) . RESULTS There was a significant difference , F(1 , 58)=7.44 , p < .009 , between males and females for relative VO2max , but not absolute ( p=.69 ) or percent VO2max ( p=.73 ) . Regression analysis identified KBIT , age , and mean time above the THZ as significant predictors of performance in the  Stroop Color-Word condition , F(1 , 56)=5.21 , p=.02 . KBIT and mean time above the THZ were significant predictors for Trails B , F(1 , 56)=7.60 . CONCLUSIONS These results suggest that heart rate , as a measure of physical activity intensity , should be closely monitored during research that is intended to make inferences about its effects on cognitive performance as participation in vigorous activities may have specific benefits over lower intensities among prepubescent children
