Because it burns calories so quickly, aerobic exercise is a threat to the body’s energy reserves. Heeding this danger, the body acts to protect one of its most precious, and energy-demanding, organs: the brain.
…
By acting as a mild stressor, exercise is an alternative way to spur many of the protective benefits associated with calorie restriction and the release of brain-building growth factors, said Carl Cotman, director of the Institute for Brain Aging and Dementia at the University of California in Irvine.
What kind of exercise? Well, running is quite effective:
Even when we are sitting or lying down, our bodies send our brains regular updates about how our limbs are positioned. When we, say, stand and begin walking, these electric messages need to be sent more often. (Knee is bent, straight, bent, straight …) Move fast enough and the electrical activity doesn’t have time to dissipate between each message. It begins building up in the brain and eventually triggers a release of chemicals called growth factors.
Growth factors are like manna for neurons. “They make neurons stronger, healthier and improve their ability to learn,” Cotman said.
Anaerobic activity does little to aid the brain via this mechanism, but aerobic activity seems to do the trick.
Our Sheriff’s department uses it (along with other services by the same company), and it’s downright scary the ammount of stuff they can pull.
Want all the blue and gray SUV’s that have a 9 and an F within a 100 mile radius of a given location? It can pull that up. Want to find out if a particular person has ANY connection to the owner of that vehicle. It can do that. As a demonstration it was able to connect our sherrif to a woman that his wife had been roomates with over 20 years ago (before they were even married).
It was astonishing how much information it could coordinate on any person in the room that we plugged into it.
I wonder what they know about me. Then again, Facebook and the internet probably make their job pretty simple for my generation.
