The main reason is that a deeper stretch activates the GTO and spindles so while you are physically trying to increase ROM, your body is working against you. Also, I think they theorize that extreme stretching causes microtrauma that results in improper alignment of the myosin crossbridges, leading to impaired muscular function. Do I believe it? Some of it is probably based off good science, but that doesn't mean it is actually true.
