Overview
- The peer‑reviewed study tracked about 3,800 impacts on 203 athletes with motion‑sensor mouth guards and video and recorded 47 diagnosed concussions.
- Analysts found blows to the center of the head — hits to the top, between the eyes, or backward falls — were more predictive of concussion than off‑center hits that mainly rotate the skull.
- Lab tests reported in the paper showed helmets with a fluid‑filled cushion lining reduced concussive outcomes from center‑head impacts compared with standard helmets.
- Researchers and outside experts say the results challenge the field’s rotation‑only model but are preliminary because of the modest concussion count and need for replication in other sports and populations.
- The finding arrives against renewed concern about long‑term brain disease in contact sports and could prompt closer clinical screening for linear impacts and new directions in helmet design if confirmed.
