A few months ago, a high school graduate contacted me with a request for an interview for her “Matura thesis”. The topic of her thesis was the (possible) ban on headers in children and adolescents in soccer. Shortly afterwards, the same question came up at the general assembly of the Society for Paediatric Sports Medicine (GPS): why are headers banned in youth soccer in England/US, but not in Germany and Switzerland? Reason enough to take a closer look at this topic and try to find evidence-based answers to this question.
