Obese kids or those with lesser aerobic fitness are as smart as their leaner peers finds a study that analysed associations of fitness motor competence and adiposity with cognition. The study led by researchers from the University of Eastern Finland showed that children with different levels of aerobic fitness or body fat percentage did not differ in cognition.

The results also show boys with better motor skills had a smaller increase in their cognitive skills
