I was an exercise science major in college and I have to wonder if all of these injuries had to do with overtraining. Yes, teams practice long and hard all year long. But, when it comes time for Worlds, coaches bump it up a notch and some have their teams practicing everyday, or if not everyday then for 4 or 5+ hours at a time. I understand that their intentions are good because they want their team to do well, but I also know from school that there needs to be a certain amount of recovery time between exercising and working the same muscle groups over and over. Overtraining is a bit more serious than most people understand. I know some of the injuries this weekend were freak accidents, but I for sure think a few of them had to do with overtraining and I hope coaches, gym owners, and athletes can learn from this.
