Exercising may help boost memory because it triggers a protein which boosts brain cell growth, scientists believe.
For several years, researchers have noticed that aerobic exercise, of the kind which gets the heart pumping, also appears to improve memory and learning. But nobody knew how.
Now researchers at the National Institute on Ageing in the US have discovered that when muscles exercise they produce a protein called cathepsin B which travels to the brain and triggers neuron growth.
The team has also shown that the levels of the protein soars when humans exercise.
"Overall, the message is that a consistently healthy lifestyle pays off,” said senior author Dr Henriette van Praag, a neuroscientist at the National Institute on Aging in the United States.
“We did a screen for proteins that could be secreted by muscle tissue and transported to the brain, and among the most interesting candidates was cathepsin B.
“Moreover, in humans who exercise consistently for four months, better performance on complex recall tasks, such as drawing from memory, is correlated with increased cathepsin B levels.”

It also helps depression.
I exercise A LOT...and my brain has gotten so large, I outgrew my "Make America Great Again" cap.;-)
They do not define a long term exercise regime.
I suspect it would correlate with an effective aerobic exercise regime.
If this was true, jocks would be the smartest people on the planet.
Yeah...don’t ya just love the “specifics” writers forget.
Think of how dump they would be if they didn’t exercise a lot.
save for later
Soon a market will develop for taking this in pill form.
LOL!!! Thank you. I was starting to feel stupid neglectful.
Exercise may well cause cognitive improvements, but it is a stretch to conclude that cathepsin B is how it works.
It is just correlation that has been demonstrated. Increased cathepsin B may just be a marker of stress from exercise.
Looking over the Wikipedia article for cathepsin B, it does not seem to have demonstrated positive effects - in fact it seems damaging.
Depends on the sport. Those with high probability of head impact, probably not.....but long distance runners, bikers (NOT motor~), and similar do seem to fit the bill.
Scientists prove things and the. are constantly reversing themselves.
My doc just told me not to eat canola oil... Use butter. It’s like in that woody Allen movie sleeper. (Yeah I know Woody is a deplorable
incestuous Pedophile)

FYI. These garbanzo brained aliens from “The Cage” we’re all women.
Mine must be pretty small by now...lol
Now how do I post an image? I've forgotten again.
Yeah, yeah, yeah. Just stick to the old adage: Do almost all things in moderation and take all these studies to where the sun don’t shine.
That explains a lot. I keep meaning to exercise, but I forget.
Exercise is my Prozac!!
