Researchers recently explored how football helmets safeguard players during impacts. They focused on two types of forces: translational and rotational accelerations. Translational acceleration involves a change in velocity, while rotational acceleration refers to how fast the head spins when hit, especially at angles. Measuring both is crucial since most head impacts involve both types, according to expert Nauman.
Previous research in Nauman’s lab identified the Riddell SpeedFlex and Vicis Zero 1 helmets as top performers for reducing these impacts. In their latest tests, the team examined the 2022 Riddell SpeedFlex, Vicis Zero 2, as well as two specialized models—the Vicis Zero 2 Trench for linemen and the Vicis Zero 2 QB for quarterbacks.
The findings were notable: helmets reduced translational accelerations by 64% to 87% and rotational accelerations by 44% to 88%, based on the model and type of impact. Generally, helmets do better at handling translational forces. However, experts like Nauman stress that rotational forces can lead to severe injuries.
Interestingly, the back of the helmets showed the poorest performance across all models. “Every helmet we’ve tested has a dip in performance at the back,” said researcher Bucherl. Nauman added that this is particularly concerning for players like receivers, who often result in falls that cause direct hits to the back of the head.
Looking at trends, a recent survey showed that 78% of football players worry about head injuries. This highlights a growing awareness around safety in contact sports. As technology advances, helmet designs are likely to keep evolving, aiming for better impact protection.
