what is the change-up pitcher doing that would be considered internal rotation vs. a pitcher taught the traditional method of being on top of the ball from 12 - 9 o'clock.
IMO nothing because she is not trying to whip the ball for speed. If throwing a "backhand change" both pitchers will have to turn their forarm early enough to allow for the backhand release. They'll have to learn when and how to get there through practice.
Based on everything I have seen I do not believe there is such a thing as a "traditional" method that has ever been used by top underhand fastpitch players whether male or female. The IR method is the way all of the good ones have thrown. The teaching that has taken place that involves -fingers behind the ball, pull down, snap the wrist hard at the hip and follow up in a muscle position was based on a series of assumtions and perpetuated by good meaning people who were trying to find a systematic method of teaching. The benefit of video analysis and the help of teachers like BM and Bill (on this board) help demonstrate the method is not correct for throwing underhand. It reminds me in hitting of "squash the bug, hit down on the ball and have arms extended at contact". A huge number of "hitting coaches" with experience and credentials perpetuated these ideas but we know they are not correct or what good hitters do. I do not believe IR places more strain on the shoulder than another method. When I am pitching practice my arm has less fatique than ever thanks to IR. When the instructor understands IR she will understand this by experiencing it for herself.I recently mentioned IR to my DD's pitching coach and she was concerned that IR might put more strain on the shoulder than traditional methods, especially for new pitchers. Thoughts?
Now here is a cool challenge...If your pitching coach has pitched successfully in the past get video of her pitching a few balls at speed. I bet if she is good she is using IR. If she doesn't pitch get her best student on tape. If they are good I bet they are using IR whether they know it or not. If she does not pitch well or have a good student...get a new pitching coach.
