I'm glad someone is finally talking about this. The fact that stretching makes connective tissue longer and that "warming up" enhances blood flow has never been dispute. Neither have ever been shown to prevent injury. Ever. Of greatest interest to me is the tendency of the medical and therapy communities to continue to insist that they do. I don't expect this to change in my lifetime. On the same track, is there a study out there demonstrating a correlation between posture and pain? Barrett L.
