How Marathon Running Affects Brain Myelin Levels

Effects of Marathon Running on Brain Myelin

Running a marathon can lead to a temporary decrease in brain myelin levels. This change is not permanent; myelin levels typically return to normal within two months. Researchers suggest that during extreme exertion, the brain may utilize myelin lipids as an emergency energy source.

This phenomenon highlights how our bodies adapt to strenuous activities. Understanding these changes can help athletes optimize their training and recovery strategies.
