The Brain's Adaptation to Marathon Running
Running a marathon may lead to temporary changes in the brain, particularly a decrease in a fatty substance called myelin, which helps with nerve signal transmission and makes up a significant part of brain structure. Research indicates that as runners exhaust their energy reserves, their brains may utilize myelin as a source of energy, similar to the body burning fat for fuel. However, these changes are not permanent; follow-up studies reveal that myelin levels return to normal within two months after the race. This phenomenon offers insights into neurological disorders where myelin degradation is chronic, potentially aiding treatments for conditions like multiple sclerosis.
