The recent deaths of three young football players have sparked a fresh wave of concern about the safety of the sport. One proposed solution to this problem is the use of soft-shell helmet covers, such as Guardian Caps. But do these covers really make a difference, or are they just a false sense of security?

At first glance, the idea of adding extra padding to a football helmet might seem like a no-brainer. After all, who wouldn't want to protect their child's head from the potentially devastating effects of a concussion? But a closer look at the science reveals a more complicated picture.

Proponents of Guardian Caps point to lab studies that have shown a measurable reduction in the force of impacts when the covers are used. For example, one study found that the caps reduced the force of acceleration by up to 14%. But other studies have been less impressive, with some finding no significant difference between players who wore the caps and those who didn't.

So what's going on here? Is the answer to the problem of concussion prevention as simple as just adding a little extra padding? Or are there more complex factors at play?

One potential issue is that lab studies are not always representative of real-life situations. In a lab, scientists can carefully control the conditions and repeat the tests multiple times, but in real life, the variables are much more complex. Players may be wearing different helmets, or the hits may be coming from different angles. As Dr. Nicholas Murray, an associate professor at the University of Nevada, Reno, points out, "Real-life studies are important too... The results of lab studies don't always translate directly to real life."

Another issue is that there is no clear threshold of force that determines whether a hit will cause a concussion. As Dr. Murray notes, "Increasingly, science suggests that it's repeated blows to the head that damage the brain, perhaps even more than the force of those blows." This means that even if a helmet or helmet cover can reduce the force of an impact, it may not always be enough to prevent a concussion.

So what should parents do? One piece of advice from Dr. Steve Rowson, a biomedical engineer at Virginia Tech, is to choose a good helmet before considering adding a Guardian Cap. "The most important factor is which helmet the player is in, not necessarily whether or not they're wearing a cap... because some helmets test really good, and that helmet without a cap could be better than putting a cap on a poor performing helmet."

But what about the cost? Guardian Caps cost around $70 per helmet, while the models used by the NFL run $125 each. Is this a worthwhile investment for parents who are trying to protect their children?
