Study Reveals Single Header in Football Raises Brain Damage Biomarkers
Heading a football just ONCE is enough to raise levels of proteins associated with brain damage, scientists warn

A study by Amsterdam UMC indicates that heading a football just once can temporarily elevate proteins associated with brain damage in amateur players. The research highlights potential long-term risks, particularly for players in defensive positions, and suggests the need for policy changes regarding heading in football.
- 01A single header can raise levels of p-tau217 and S100B biomarkers, which are linked to brain damage and cognitive decline.
- 02Players who headed the ball more frequently or with greater intensity showed a more significant increase in these biomarkers.
- 03The biomarker levels returned to normal within 24 to 48 hours, but repeated impacts could lead to lasting damage.
- 04Experts suggest that footballs should carry health warnings about the risks of heading to raise awareness.
- 05Professional defenders are up to five times more likely to develop neurodegenerative diseases compared to the general population.

A recent study conducted by scientists at Amsterdam UMC found that heading a football just once can lead to a temporary increase in biomarkers associated with brain damage. The research involved over 302 amateur football players, who had their blood samples analyzed before and after matches. Results indicated that players who frequently headed the ball, especially with high intensity, showed significant elevations in p-tau217 and S100B biomarkers, which are linked to neurodegenerative diseases like Alzheimer's and Parkinson's. While these levels normalized within 24 to 48 hours, researchers cautioned that repeated impacts could lead to lasting damage. The findings raise concerns about the risks associated with heading in football, particularly for players in defensive roles, who are more prone to such impacts. Experts are advocating for health warnings on footballs to inform players of these risks, emphasizing the need for policy changes in the sport to protect players' long-term health.
