Amateur soccer players show immediate increases in blood biomarkers associated with neural damage after heading the ball during a single match, according to research published by Nature Medicine on July 31, 2026. The study identified dose-response elevations in p-Tau217 and S100B, proteins that signal brain stress and neurodegeneration.
The findings suggest that the repetitive impact of heading a soccer ball triggers a measurable biological response in the brain, even in non-professional athletes.
Blood Biomarkers p-Tau217 and S100B
The study focused on two primary biomarkers to measure the impact of heading the ball.
The researchers also tracked p-Tau217, a phosphorylated form of the tau protein.
The data indicates a dose-response relationship, meaning the elevation of these biomarkers in the blood correlated with the frequency or intensity of the heading actions performed during the match.
Neural Response in Amateur Players
While professional athletes often undergo rigorous monitoring, this research specifically targeted amateur-level players. The results show that the physiological stress on the brain occurs regardless of a player’s professional status or level of training.
The spike in biomarkers occurred immediately following a single game.
