Wie Fußball Körper und Gehirn verändert

Scientists discovered that professional soccer players' brains actually change shape from

heading the ball thousands of times. The repeated impacts create tiny alterations in white matter

that make players react faster to the game but slower in memory tests. Even crazier,

goalkeepers develop asymmetric leg muscles so extreme that one thigh can be two inches larger

than the other from constantly pushing off the same side. And here's the wildest part.

A regulation soccer ball travels up to 80 miles per hour during a professional match,

hitting players with the same force as getting punched in the face by a boxer.
