I havent read the papers quoted in the article. But, I'm a little puzzled reading this.. It sounds more like interpreting what they want to see or think is happening.
> Aerobic exercise appears to lead to changes in both the structure of the brain and the way it operates, which together bolster learning in kids, give adults an edge on cognitive tasks, and protect against the cognitive declines that often come with age.
Given the penultimate paragraph where they say - “You shouldn’t expect to increase your IQ or anything of that nature,” How could the above statement be true? What measure is there to say "this behavior we are seeing is increasing learning ability of the brain while not increasing the IQ"?
> so the brain was able to better identify specific features during exercise.
and
>and found the same thing: After exercise, one’s senses are heightened and thus can detect the flashing at a higher frequency than before exercise.
Sure, but exercise is more of our body pushing itself to do something. Does this mean the same behavior is observed or even amplified when you cordinate that level of work and play sports instead? Then why not recommend people to play sports that need more brain work (strategy, using senses to stay sharp, motor skills etc). One would assume the more you flex your brain muscle it gets "better" No?
> They discovered that the brain uses some of that(extra energy from glucose and carbs due to increased heart rate) fuel to build more neurotransmitters, the chemicals that relay messages around the nervous system.
How does this compare to say playing chess or playing Tennis?
I'm not disputing the article. I'm trying to understand the logic and get better results by playing sports instead of running while watching Netflix on the phone.... Am I getting it wrong?
- wjnc 8y agoMy reading is the following. Say my IQ is pretty constant. As any father can attest to, there are a lot of factors influencing whether I'm on top of my game. A few rough nights and I'm in a worse state for days. Let's say exercise usually is correlated with better sleep, better cardiovascular operation etc. and also the other way around (I train less when tired). Then I can easily follow better performance after training but also for groups that exercise more. You just make better use of your potential (IQ).
- Tenoke 8y ago>As any father can attest to, there are a lot of factors influencing whether I'm on top of my game. Off-topic but I really don't understand why so many parents like to imply that only/mainly they know/experience things that are common to everyone.
- myle 8y agoGrandparent didn't claim that bad sleep patterns occur only to parents. He claimed that all parents have experienced bad sleeping patterns.
- Tenoke 8y agoI said imply, not claim.
- wjnc 8y agoThat was only example from my life. Other episodes with the same outcome were too much partying in college, sleep deprivation because cool when a teen. I guess we all have examples where we are totally outside a normal balanced state of mind with detrimental effects to our mental well-being! My point was more generally that in person IQ is constant but life factors and choices can lead to sub-optimal outcomes intelligence wise.

- knicholes 8y agoBeing awakened every night, sometimes multiple times a night, for years is common to everyone?
- Tenoke 8y agoNot being at the top of your game because you are tired (which is what the point was) is.. If one only has that experience after they become a parent - I can only envy them.

What measure is there to say "this behavior we are seeing is increasing learning ability of the brain while not increasing the IQ"? Here are some examples: 3 days without sleep will give you IQ performance 20 points less than your previously measured brain IQ. That doesn't mean you permanently got dumber. Similarly, exercise can make you perform better at cognitive tasks, while still retaining the same IQ. Reduced blood flow to the brain (e.g. due to apnea/obesity) can make you actually lose tons of IQ points (sometimes even permanently). Exercise prevents those things.
