In a study two groups took a memory quiz. Then one group cycled to exhaustion in 30 minutes and the other group sat there. Their memories were then retested. The result:
“The exercised volunteers performed significantly better on the memory test than they had on their first try, while the volunteers who had rested did not
improve” – quote from the NY Times article How Exercise Benefits The Brain.
They also took blood samples throughout the experiment. They found that: “The cyclists had significantly higher levels of a protein known as brain-derived neurotrophic factor, or BDNF, which is known to promote the health of nerve cells. The men who had sat quietly showed no comparable change in BDNF levels.”
In a Brazilian study published last month, “scientists found that after sedentary elderly rats ran for a mere five minutes or so several days a week for five weeks, a cascade of biochemical processes ignited in the memory center of their brains, culminating in increased production of BDNF molecules there. The old, exercised animals then performed almost as well as much younger rats on rodent memory tests.”
