The marathon racing may seem like the final sport to stay in shape. However, it may take a file HeavyIt is possible that it will harm the kidneys, which disturbs the stomach, which increases the risk of heart failure, and leads to muscle muscle injuries. Let’s not forget that the original marathon runner, ancient Greek soldier Fededidis, is said to have Death dead Immediately after reaching his destination.
Now, a new study indicates that the marathon also affects the brain – causing the same organ to eat for lost fuel during running.
In the research, March 24 was published in the magazine Nature metabolismScientists have noticed a decrease in a major biological mark in the myelin, the fatty tissue that isolates the bonds between the brain cells, in the marathon contestants after the race. The authors of the study say that this indicates that the brain consumes myelin as an energy source under these harsh conditions.
Fortunately for long -distance hostility, these effects appear to be vice versa.

Once the body is exhausted to supply the standard energy source – glucose, or sugar – it turns into spare generators, which leads to fat metabolism as an alternative source of fuel. The brain, in metabolism, is more than my hamx than hatchback. Eerspatients are devoured by energy 20 % of the body’s energyThis means that he can quickly harm if the fuel sources are short.
Pedro Ramos Kabir -I tell the nerve scientist CIC BIOMAGUNE, a non-profit research institute in San Sebastian, Spain, and a co-author of the study-living science that he and his colleagues wanted to determine the reserve energy sources in the brain. They were suspected that the fatty myelin could be the answer. former research In rodents, I suggested that the fatty acids produced from the collapse of myelin can help increase the survival of the cells in the brain. Whether these results before the clinical will be repeated in humans were still a mystery.
“We needed to exhaust all the sources of the body’s energy to prove this,” Kaber told Live Science.
The team wiped 10 contestants brains 48 hours before the Marathon Administration and then two days, two weeks and two months after that. They used magnetic resonance imaging, which could reveal the presence of the besieged water molecules between the layers of myelin.
Brain tests showed that, after two days of running, magnetic resonance imaging signals were exhausted in 12 areas of the brain compared to before the race-in some cases, up to 28 %. The changes in the total levels of myelin in the brain were not statistically significant, indicating that any changes were very isolated in specific areas.
“The areas we have seen have more important changes are those related to the kinetic circles and the center of emotional control of the brain.” He suggested that this reflects the mental and physical effort that the brain must keep to get a marathon.
For any of the contestants worried about eating human meat in the brain, there is good news: after two months, all myelin contestants recovered to the base line levels.
Klaus Armen SouenThe manager did not participate at the Max Planck Institute for Multidiple Sciences in Germany, but also it He studied how the milen stores energyUsing laboratory mice. Naf said that the results of the paper are in line with how myelin neurologists believe in the brain.

“The myelin is constantly made and deteriorated,” he said. “It resembles the bathtub in which it is constantly filled with water and drains it constantly.” He added that the work of Kabeer provides “very strong evidence” that after the marathon race, the metabolism of the brain increases. Consequently, the fuel stored in the myelin is more exhausted quickly than usual, which leads to brain contraction.
The results do not mean that the contestants should avoid the marathon on behalf of their brains. NAVE and Cabrler pointed out that the size of the small study means that more work is needed to extract concrete conclusions on the effects of marathon on the brain. They added that the very limited effects on myelin in general are the need for more research.
However, these effects may carry increasing risks for some athletes. For example, in people with atrophic lateral sclerosis (ALS), metabolic molecules are usually made by myelin BriefThe researchers believe that excessive exercise can exacerbate the problem.
Kaber said that more research would be needed to confirm this theory.
