Sports like girls soccer have been calculated to result in 33 concussions per 100,000 player outings and wrestling has about 24 concussions per 100,000 player outings a year, according to The Head Case Co. In comparison, the most recent study — completed in 2012 — shows that at least one football player sustains a concussion for every game played.
On the same note, while soccer has fewer concussions per year when compared to football, the severity of concussions sustained in soccer is significantly higher.
"Recent studies show that soccer has surpassed football," said neurologist Peter A. Puzio from Augusta Health Neurology. "As soccer grows in popularity, so does the incidence of concussion. There's not a perfect a number because it all depends on the severity of each one, but there is a cumulative effect of concussions. One is bad, but it depends on the severity of the concussions."
At the same time, he says, football has seen measures taken to reduce incidence of concussions. It has also become more common for football players to quit the sport for fear of developing CTE.
