The benefits of regular physical activity on the brain are well known. Researchers have discovered a molecule that activates during physical activity and protects the brain.
As we know, physical activity has many virtues for the body and the brain. The scientific literature on this subject is prolific. But we do not yet understand how sport protects the brain. Researchers fromharvard medical school (Massachusetts, United States) are interested in this question. The results of their study appeared on October 10 in the journal Cell Metabolism.
Irisin: a good protein for the brain
When playing sports, the body secretes hormones and activates molecules. The one that Harvard researchers have discovered, called FNDC5, has a special property. It generates the protein “irisin. Its benefits are already known since it transforms white adipocytes (adipose tissue cells that consume little energy) into brown adipocytes (which consume more energy). In other words, it helps burn fat.
Researchers artificially increased the level of irisin in the body of mice by exercising them. They found that this protein activates genes responsible for learning and memorizing in the brain. Irisin also has properties that improve cognition. But it also has neuroprotective effects. A potential weapon against neurodegenerative diseases, according to researchers.
The mechanism of the FNDC5 molecule is not yet known. Researchers are currently trying to stabilize the protein in order to control its level. Eventually, an irisin-based drug could be developed. It would protect the brain and improve cognition.
30 minutes of physical activity per day
While waiting for this miracle drug, it is possible to naturally activate irisin … For this, 30 minutes of moderate physical activity each day is sufficient. This time will not be wasted since the benefits for the body and the brain are very numerous. Fitness or aerobics limit the progression of multiple sclerosis. Moderate physical activity promotes connection between neurons, concentration, memorization and alertness. It also protects against brain damage and reduces the risk of diseases such as Alzheimer’s or certain types of cancer.
For those who do not know where to go, the website of the National Health Nutrition Program even offers a tool to find where to move near you. So no more reason to sit still in front of the TV.
