Some teenagers appear to present changes in their brains after 1 season of playing USA football, a little study advises.
Even though football players were not concussed during the season, experts found problems similar to the effects of mild traumatic brain hurt.
24 players aged between 16 to 18 were tested and gadgets on their hats measured head impacts.
The study was showed to the Radiological Society of North America.
In last year’s, a number of reports have showed concern about the possible effects on young, developing brain of playing contact sports.
These studies have focused on brain changes as an outcome of concussion.
But this study fully focused on the effects head forces on the brain, even when football players did not suffer injury at any point during the season.
Using detailed scans of the American footballer’s brains before the season start and then again after it closed, the experts were capable to identify slight changes to the white stuff of the brain.
White stuff contains millions of nerve fibres which work as communications wires between the brain regions.
Those football players who were powerfully harder and hit more often were more likely to present these changes in post-period brain scans.
Dr Alex Powers, paediatric and co-author neurosurgeon at the Wake Forest Baptist Medical Center, said the changes were an open result of the hits got by the young players during the football period.
“USA football is an open contact sport. The aim is to bring people down.
“When football players are hit, the brain moves badly within the skull. The strongest the hit is, the more the brain is going to move.”
He said the changes could not be known as brain injury because they do not yet understand if the changes were reversible or not.
Their next goal is to find out when young, developing brains are their most in danger- in order to make the sport secure for everyone.
Antonio Beli, trauma neurosurgery professor at the Birmingham University, said 3 was a lot of interest in these types of injuries, but there was still more research to be completed.
