>Boxing, MMA The biggest difference is that most parents don't sign their kids up for Boxing in kindergarten. I was a big kid (I'm 6'5" now), and I live in the south, so of course my parents signed me up to play football at 6. In other sports where kids start very young, like soccer, the contact injuries are usually a result of accidents. You aren't trying to slam into people at full speed.

Its pretty common to use your head to physically stop or even change the direction of the ball in Soccer. There are accidents of course, but the standard norms of Soccer still don't seem very healthy for the brain. I'm aware of the "Football towns" across USA. Basketball is bigger in my area though, which might be why I hear more about Basketball-related injuries.

  Youth soccer in America has rules against heading the ball. Under 11 can't do it at all, and there are time limits and incidence limits for kids older than that (though it probably needs to be outright banned for minors). In addition to concussions, football players are also believed to receive repeated microtrauma from running into each other repeatedly, which contributes to CTE. Football is a full contact sport. In games and in training, you are repeatedly slamming into people at full speed. There is nothing comparable in soccer or basketball outside of accidents (which by nature of being accidents happen much less frequently).
