Scientists in American have discovered that the brains of children who are fit and active grow larger than their couch potato counterparts.
Researchers at the University of Illinois found that one of the most important parts of their brain was some 12 per cent larger in fit children than in those of unfit youngsters.
The study, published in Brain Research, concluded that the findings should encourage children to take up sport from a young age. Professor Art Kramer who led the research said: 'We knew that experience and environmental factors and socio-economic status all impact brain development. If you get some lousy genes from your parents, you can't really fix that, and it's not easy to do something about your economic status.
'But here's something that we can do something about. This is the first study I know of that has used MRI measures to look at differences in brain between kids who are fit and kids who aren't.'
What do you think? Have you noticed differences in levels of intelligence in sporty and non sporty children?
