I don't know how common this is but in my area I know of a couple of High Schools who added a seventh period of soccer training. I don't know what they call the class but my understanding is that it's a way to get away with early practices for the HS season. They do conditioning, strength training and soccer practice five days a week. They don't give exceptions to club players and they have to take the class to play on the team. Two of the three girls on our team who go to these schools are now injured due to over use injuries. It is way too much volume. It is extremely frustrating and should not be allowed at least if the student is playing club soccer. IMHO those HS coaches are complete idiots.
