I realize that people make this sound when punching/striking to make sure they are breathing properly (among other reasons) and this thread http://www.sherdog.net/forums/showthread.php?t=274567 seems to bear that out. However, has anyone ever thought that making an audible SHHHHHH sound when punching can actually turn out to be a "tell" when striking. I am not a professional by any means, but I seem to be able to time people's punches in sparring because they often make this shhhhh noise a split second earlier or at about the same time as they initiate their strike. Also, people will often shhhh in a rhythm that can tell you what is coming next. For example a long shhhh that trails off at the end is usually a heavier punch that is not immediately followed up, while a quick shhhh with no variation in tone usually means it will be quickly followed by more quick shhh (i.e. a combination). Has anyone else ever noticed this?
