Probably outdated material. I keep up big time with this type of stuff and that line of thinking was touted by kinesologists of the 1970s and 1980s. Most new school research will support what I posted in the last post. Mechanics is definitely the most importance in predicting future injuries. Secondary is pitch counts and power vs finesse. Though I would be interested in reading over the studies that you talk of, if you can point me in the right direction I can access them.
I'm interested to see how Nolan Ryan's experiment works out. Pretty promising right now, but it takes a year or two for these things to kick in.
We should talk more about this in another thread sometime. I'll find some of the stuff that I have read. I've seen a lot that argue both sides. IMO, pitch counts really don't matter THAT much. 100 is the magic number (as usual) that teams stick to for some reason.
