It's no surprise one would incur a concussion playing soccer. Head-to-head contact on header balls would seem to be a particular area of vulnerability. But you may have missed the point about the football studies.
Studies suggest a typical concussion of mild to average severity does not result in a permanent pathology. Rest and contact-avoidance for a couple of weeks is what the doctor orders and will set things right. NFL protocols follow this time-honored process...concussed players typically sit out one game after the event...a 14 day hiatus, give or take.
The problem with football, the problem the NFL is struggling with and playing dearly for, comes from the research indicating the affects of concussions are cumulative if regularly repeated. Further, the research suggests constant sub-concussive contact may have deleterious long term affects.
The main question I would have about soccer is the sub-concussive events. I'd question whether repeatedly bouncing a soccer ball traveling 50 mph off your head is an innocuous practice. I've not looked at soccer studies, and I couldn't say whether there have been any performed. Perhaps the life expectancy of elite soccer players is also well below average as with ex-NFL players? I think I'd want to know that as a starting point if I had a personal involvement.
Interesting. That is something to think about. Informative post.
