A new study finds heading a soccer ball causes immediate head injuries.
The research by Scotland's University of Stirling published in EBioMedicine is the first study of its kind, it looks at direct changes of the brain in players that are exposed to everyday head impacts, instead of traumatic brain injuries like a concussion.
The study looked at 19 amateur men and women soccer players. The players were asked to head machine-projected soccer balls at speeds mimicking routine soccer practice.
After just one heading session, players experienced increased inhibition of the brain and significant memory loss, with the effects normalizing within 24 hours. University of Stirling says scientists involved in the research hope this study shows the potential cumulative impact of brain injuries in soccer and stress players' long term health should be monitored.
