Football helmet covers do not reduce concussions for high school players

A study of 2,610 Wisconsin high school football players found that wearing soft-shell helmet covers, marketed as Guardian Cap helmet devices, during practice had no effect on the rates of sports-related concussions.

• Researchers observed no statistical difference in concussion rates between players who wore Guardian Caps and those who did not (33 vs. 31 concussions, respectively).
• Previous lab tests suggested Guardian Caps could reduce helmet impact forces, but real-world study found no protective benefit during practice.
• Other factors such as prior concussions, helmet brand, playing surface or years of experience did not affect concussion risk.
• Notably, female players had a significantly higher rate of concussion (18.75%) compared to males (2.4%), though the sample size limits this finding’s application to the larger population.
• The study recommends evidence-based interventions like safety training for coaches, adding jaw padding, presence of athletic trainers and reducing practice contact, which have been shown to reduce concussions by up to 64%.

Guardian Caps did not offer lower concussion risk in high school football practices and relying on them may offer false reassurance; data-back strategies remain the most effective means of concussion prevention.
