Heading a soccer ball may not be as harmless as it first seems

Heading a soccer ball may not be as harmless as it first seems. British scientists got soccer players to head a ball fired from a machine designed to simulate a corner kick 20 times in a row, testing their brain function before and after the experiment. The outcomes suggest small changes in brain function even after a single session with memory test performance dropping by between 41% and 67%. The effects normalised within 24 hours and it is unclear whether any changes would remain temporary after repeated heading sessions.
