Wow... Please do not rely on an animal model to make lifestyle choices. What this article needed to answer the question was IQ tests conducted possibly right after exercise and later in the day for people exercising in specific ways and not exercising at all.

An IQ test wouldn't indicate more neurons.

  They can infer size with fMRI. The article claims it's good for the brain. What does it mean to be "good for the brain"? What people want to know is not how many neurons there are but whether cognition gets better. And that is indeed the case: http://www.ncbi.nlm.nih.gov/pubmed/21282661 http://www.ncbi.nlm.nih.gov/pubmed/21282661

Today there is no way to increase your iq. Exercise may improve your attention, emotion regulation, reduce stress.

  That is not true at all. There is a very easy way to increase your IQ - just study for IQ tests!

      If brain structure stayed static throughout your lifetime I would be inclined to agree. But as the structure is constantly in flux, and proven so, no so much. Granted there is disagreement on how much your iq can change over time. http://www.livescience.com/36143-iq-change-time.html http://www.livescience.com/36143-iq-change-time.html

        May be I needed to be more clear. Of course there can be variations, but the maximal potential iq is static throughout life and we can't change it. Good nutrition, good environement will help someone achieve it, I don't know about exercise.

        ^ What he said. IQ is a measurement of capacity for development. So if you are perfectly healthy, have perfect nutrition, perfect exercise, perfect learning, etc. you could perfectly realize your development. This is unlikely to happen, and there are various things (malnutrition, lack of exercise) that can lower your performance IQ temporarily, but you can't really change your capacity for development. And you can't add to it.

        You're mistaking IQ with the underlying factors which it is derived from. IQ is, by definition, just a function of your scores on a bunch of standardized tests which try to determine your intelligence. If you can study for the kinds of questions the tests ask you, you can improve your IQ. It is a different story from improving whatever the underlying factors are. For example, some IQ tests ask you "What's the next number in this series...". If you aren't very good with numbers, you might do very poorly on this section. However, if you sit down and learn about a lot of the patterns that show up frequently in those types of questions, then you may increase your score dramatically on that section, and thus improve your IQ.

This is a misunderstanding of the claims in the article. They are claiming that exercise leads to improved brain function over the course of weeks and months, not that being tired right after doing exercise will improve brain function.

  You cannot apply these things to humans from an animal model. Also, if it works over months you'll see it increasing over months according to the procedure I descibed (and that has been previously done on humans in other studies). If there are short term effects, those would also show up.
