Jan. 27, 2000 (Atlanta) -- A new study suggests that, from a medical perspective, the recent hit movie Fight Club might accurately have been called "Concussion Club" instead. That's because researchers have found evidence of traumatic brain injury in a group of amateur boxers in the Netherlands, despite the use of protective headgear.
The study, which is published in the latest issue of The Physician and Sportsmedicine, compared the mental function of 38 amateur boxers, before and after a bout, with that of 28 amateur boxers who did nothing but hit a punching bag.
Overall, the group that boxed scored lower on tests of planning, attention, and memory -- but similar to the non-boxing group on tests examining how fast they could process information and pay attention. But the researchers found that the intensity of individual boxing matches did affect results. For example, "impact" -- a factor of weight and number of punches -- reduced scores on a visual short-term memory test, while knockouts (KOs) and technical knockouts (TKOs) were associated with a decline on a verbal memory test.
While only 13% of the fights ended in a KO or TKO, the researchers say that blows to the head were common -- with 35% of competitors getting punched in the head more than 10 times during a match. They conclude that amateur boxing is thus a potentially dangerous sport, because of the risk of acute traumatic brain injury (ATBI).
But the news isn't all bad for boxers, according to one of the study's authors. "The take-home message is that you can have some subtle cognitive impairment with amateur boxing," co-author Barry D. Jordan, MD, director of the Traumatic Brain Injury Program at Burke Hospital in White Plains, N.Y., tells WebMD. "However, I think, as with most types of concussions you see in sports, these are self-limiting." Jordan does say, however, that amateur boxers who get a concussion shouldn't fight again without proper medical evaluation.
He also tells WebMD that the study confirms the long-held notion that "protective" headgear -- when it comes to boxing -- is a misnomer. According to Jordan, the gear does nothing to stop "rotational acceleration," the injury that occurs when the head rotates to the side after a blow.
