Why do athletes risk their brains?

Murphy’s retirement is a sign that concussion culture in the AFL is beginning to shift.

Although the long-term implications of multiple concussions and repetitive neurotrauma have been recognised internationally for nearly a century, scientific and health knowledge has historically battled against a warrior culture in contact sport communities.

For decades, sports have fostered a win-at-all-costs culture, with a pseudo-military flavour of sacrifice and duty to one’s teammates.

This has given rise to athletes ignoring or downplaying injuries whenever possible to continue the game.

This behaviour is particularly easy to enact when it comes to concussion, because it is often an invisible injury with health effects that may not manifest until after the initial contact.

Compounding this are expectations from spectators and fans, many of whom expect their heroes to “run through walls” and not show any weakness or vulnerabilities.

Media commentators also celebrate athletes who return to the field after sickening collisions as “courageous”, having “no fear”, or “gaining respect from teammates and opposition”.

There have been public calls since at least 2016 for commentators to change to the language around concussion.

A shift in attitude?

To prioritise athlete welfare, outdated attitudes need to change across Australia’s multiple contact sporting codes.

Murphy’s retirement and acknowledgement of his long-term brain health is one sign the culture of valorising injury and risk may be changing. But there is other evidence of a shift.

Australian research shows risky attitudes and behaviours toward concussion have begun to dissipate over recent years.

In 2017, the first study of concussion attitudes and behaviours in Australian athletes at all levels showed that despite participants knowing the dangers of concussion, many would still choose to play through or hide concussions.

Others revealed that even if diagnosed with a concussion, they would not complete full rehabilitation in the hopes of returning to the field sooner.

However, a 2021 follow-up study, using the same survey in a separate group, showed significant improvements towards concussion. Respondents were much less likely to hide or play through a concussion, and were more likely to complete full rehabilitation before returning to competition.

This data indicates that athletes are not only more aware of the potential long-term health effects of brain injuries, but are more likely to heed medical advice if they are concussed.

Murphy’s retirement is an example of footballers’ increased willingness to listen to medical advice. His decision was informed by the findings of the AFL’s independent panel of medical experts, which was introduced in 2019 to provide players with advice about whether to continue their careers following brain trauma.

In his announcement, Murphy said he accepted the panel’s advice, something we hope to see more of in future.

It should also be noted that in October 2023, this advisory panel permitted Murphy to return to training after the athlete was knocked out during September’s AFL Grand Final.

This short turnaround indicates the line between safety and danger for athletes’ brains is razor thin, and that athletes, their families, and medical experts like those who advised Murphy have a complex job ahead of them, as more and more athletes contemplate their futures post-concussion.
