^ interesting how bodybuilders and athletes arent known for their intelligence yet there are more articles on excercise and NGF, BDNF, neurogenesis in general than any other compound or anything else natural there is, that it puzzles me why arent they?
Most successful and intelligent people are healthier than the rest of the population and habitually do aerobic and anaerobic exercise.
So, maybe there is a correlation between exercise and intelligence, we just don't identify as bodybuilders.
You're right, there's a strong relationship between exercise and cognition.
Unfortunately, i'm on the wrong computer to give you lots and lots of references to this.
But here are some key ones:
1. Influence of Exercise on Cognitive Abilities
http://www.ncbi.nlm....les/PMC3951958/
2. Exercise, Brain & Cognition Across the Lifespan
http://www.ncbi.nlm....les/PMC3220305/
The gist is... exercise causes growth factors to be secreted: eg. growth hormone & testosterone/estrogen etc.
These in turn cause the release of neurosteroids... and these directly affect cognitive functioning.
Exercise builds muscles *and* brains.
There's also the detox effect of exercise. Basically, the increased blood circulation and blood pressure
causes changes in the liver and kidneys which result in the excretion of toxins following exercise.
The longer you stay sedentary and inactive... the more your body accumulates toxins.
Exercise is a powerful detox mechanism.
I remember reading one paper that suggested that rather than spend 30 to 60 minutes
playing Sudoku or doing crosswords, you could use that time more effectively (from a brain health perspective)
if you went for a long walk or medium run. (Sorry, no reference for that, but perhaps you can google for it)
be happy
