A soaring header that ends in the back of the net is one of football’s most thrilling moments. But behind the spectacle lies a growing scientific concern: every contact between head and ball sends energy back into the brain and researchers are beginning to understand just how significant that impact can be.
The conversation around heading in football has been shaped in part by the tragic case of Jeff Astle, whose death after years of neurological decline became the first linked to repeated heading of footballs. His case opened the door to deeper investigations into the long-term effects of the sport on brain health.
According to an online article, the new research from Loughborough University is shedding fresh light on the issue. Backed by The Football Association, the study examined how different football designs affect the amount of energy transferred to the brain during headers.
Using an advanced surrogate head model fitted with pressure sensors, scientists recreated match-speed impacts with balls from across different eras. For the first time, they detected a distinct pressure wave travelling into the frontal region of the brain, a finding that suggests heading is not just surface-level contact, but an event with deeper neurological implications.
Perhaps most striking is the variation in impact. The study found that some footballs transfer up to 55 times more energy than others. Factors such as ball design, speed, and even whether the ball is wet or dry all influence how much force reaches the brain.
Contrary to popular belief, older leather balls, often blamed for being heavier and more dangerous were not consistently worse. According to researchers, high-energy impacts occur across all generations of footballs, meaning the risk has not simply disappeared with modern technology.
This aligns with earlier findings from the 2019 FIELD study, which showed that professional footballers are 3.5 times more likely to develop neurodegenerative diseases compared to the general population. The evidence has intensified pressure on football authorities to act.
In response, The Football Association has introduced restrictions on heading in youth football, including a phased ban for children under 11. The goal is to reduce early exposure while research continues to explore safer practices and equipment.
Experts say the path forward lies not in eliminating heading entirely, but in making it safer through improved ball design, better training guidelines, and stricter monitoring of player health.
The beauty of football may lie in its simplicity, but its risks are becoming harder to ignore. As science continues to probe the effects of repeated head impacts, the game faces a delicate challenge: preserving its essence while protecting the minds of those who play it.
Can we just play football?
