Youth sports in Russia are an ugly business.

You may recall there was this nasty brawl between two hockey teams made of 8-year-olds. Well, maybe they've got so much pent-up rage because of the way the coaches treat them.

For example: this frightening video shows a soccer coach kicking a player hard in his legs, knocking him down. Amazingly, the boy is told to get back on his feet and continue on with the match as if nothing happened.

It's unclear why the coach kicked the boy. Was he trying to explain technique or was he just plain angry? Either way, it's hard to justify his actions.
