Lastly, if this coach truly forced this girl beyond the moment she said "stop" it is abuse.  He is forcing her against her will, that is the very definition of abuse regardless of motive, regardless of anything.  I don't advocate crucifying the man for it, but he definitely shouldn't be coaching these kinds of athletes who aren't required to know about proper physiological training, or who aren't of amateur or pro status and responsible for thier own education or health.  We who went to school before the 90's were trained for school sports under this type of mentality and was acceptable at the time, but we know more today and have better, safer ways to train.  I don't agree that a high school cheerleader needs to do splits to be a good cheerleader, nor should it be required.   At this level it needs to be inclusive not exclusive or professional. But if a coach needs "splitters" for the sqaud, let the kids know a year ahead, at least over the summer, to start practicing.
