Clinical Report: No Short-Term Brain Changes in Youth Soccer
Overview
A prospective longitudinal cohort study found no significant differences in cognition, behavior, balance, or brain structure and function between male adolescent soccer players and noncontact-sport athletes over a competitive season. Preseason levels of certain blood-based biomarkers were higher in soccer players, but these were not linked to heading exposure.
Background
Youth soccer is the most widely played sport globally, raising concerns about the potential impact of repetitive head impacts on brain health. Previous studies have been limited by small sample sizes and cross-sectional designs, necessitating further investigation into the short-term effects of soccer participation on the developing brain.

Key Findings
No significant differences in cognition, behavior, balance, or brain structure/function between soccer players and controls over the season.
Soccer players reported a mean of 939 headers during the season.
Preseason biomarkers tNAA, GFAP, and NfL were higher in soccer players compared to controls.
Heading exposure was not associated with changes in any measured outcomes.
Findings do not address long-term effects of repetitive head impacts.
Clinical Implications
Physicians can use these findings to inform discussions with adolescent soccer players and their families regarding the short-term effects of participation.
Conclusion
The study found that participation in youth soccer over a single season does not lead to measurable short-term changes in brain health.
