The New York Times turned to a University of Cincinnati biomedical engineer to explain the significance of a new study linking the collective force of hits in football to concussions.
In his lab, UC College of Engineering and Applied Science Professor Eric Nauman studies ways to prevent concussions in contact sports, particularly football.
The Times reported on a study by Harvard Medical School published this month in Nature Communications that found that repeated small hits, not just a single devastating one, can lead to chronic traumatic encephalopathy. The study also found that the intensity of hits is a better predictor of concussion than counting the number of hits.
"Yes, all these hits matter. They all add up," Nauman told the Times.

Nauman said the findings also demonstrate the need for better safety equipment and policies such as no-contact practices that could reduce the risk of injury.
He co-authored a study this year in the Journal of Biomedical Engineering with his former students at Purdue University that tested how well helmets made by four leading manufacturers minimized the impact of hits to the head.
"None of the helmets was uniformly good or uniformly bad, except on the back of the helmet where they were all uniformly bad," Nauman said.
"The helmets are generally designed to withstand the maximum possible impact. But that's a 99th percentile type of hit. If you can design a helmet to protect players from the smaller, more typical hits, that would be ideal."
