Football and its potential long-term effects on players' brains have been a topic of intense debate for over two decades. The fear and confusion surrounding this issue have led to a closer examination of the sport's practices, particularly when it comes to heading the ball.
The scientific community has started to shed some light on the matter, but we still have a long way to go before we fully grasp the implications of this fundamental aspect of the game. The research so far has been alarming enough to prompt governing bodies to implement rule changes, but for many, the threat still feels distant and abstract.
Some may take solace in the belief that the game has evolved, with lighter balls, different coaching methods, and a focus on ground play. However, the data tells a different story, especially when we look at the Scottish Premiership.
New statistics reveal that the Scottish Premiership has significantly more headers per match compared to most of Europe's top leagues. BBC Scotland's analysis of aerial duels and headed clearances from the start of the 2021 season until now shows a stark contrast between the Premiership and other top leagues in Europe.
In the Premiership, players challenge for the ball in the air an average of 42.5 times per match, a significant increase compared to France's Ligue 1, where the average is 28.5 times per match. The Premier League in England sees an average of 28.7 aerial duels per match, nearly 50% less than in Scotland. Germany, Spain, and Italy also have fewer aerial challenges than Scotland.
When we compare Scotland to 10 top leagues across the continent, we find that there are over 35% more heading actions in Scotland. These figures may not surprise those familiar with Scottish football, but they do raise important questions about player safety.
Since the tragic death of former England striker Jeff Astle from dementia in 2002, scientists have increasingly linked repeated head impacts to chronic traumatic encephalopathy (CTE), which can also lead to neurodegenerative diseases. A coroner investigating the death of former Scotland and Manchester Utd centre-half Gordon McQueen stated that heading footballs likely contributed to his developing CTE.
A field study conducted by Glasgow University in 2019 found that former professional footballers were three-and-a-half times more likely to develop neurodegenerative diseases, with defenders at an even higher risk. Dr. Willie Stewart, who led the study, noted that heading rates across World Cups have actually increased over the past 50 years, contrary to popular belief.
In response to these findings, the Scottish FA introduced several changes in 2022 to minimize the risk. Heading the ball was banned for players under 12, and there was a ban on heading during training the day before and after a match for professional players. Clubs were also instructed to limit repeated heading exercises to one session per week.
Dr. Jonny Gordon, the SFA's chief medical officer, emphasized the association's commitment to ensuring a safe and enjoyable environment for all players, highlighting their leading role in researching head trauma in sport.
It's important to note that playing football also has significant health benefits. Dr. Stewart's study found that former professional players were less likely to die of issues like cancer and heart disease.
So, why does Scotland have more aerial play? Former defender Willie Miller, who played for Aberdeen and earned 65 caps for Scotland, expressed surprise at the statistics and suggested a need for improved coaching methods. He believes that the health and well-being of players should be a priority.
Others who have played on both sides of the border believe it could be a cultural issue. Christophe Berra, a former Scotland and Hearts defender, suggested that the Scottish culture values a more direct, aerial style of play, which may be difficult to change.
As the science continues to evolve and we gain a better understanding of the risks, Scotland, as a leader in this research, has a crucial decision to make about the future of the game and how it can be adapted to prioritize player safety.
