I've just got to add my two cents since this is one of my favorite topics.
Motion2strike hit the first point you need to understand relative to the mind-body relationship "dead-on". What you're dealing with is that struggle between the conscious and subconscious mind to control your performance in bowling. The subconscious mind controls your "muscle memory". That is the physiological function that allows you to perform an approach without being required to concentrate on each and every muscle movement...similar to a proficient typist (that would not be me)that does not need to look at the keyboard while typing. How do the fingers find thos small targets on the keyboad so rapidly without the typist looking at his or her fingers? That is my best example of muscle memory.
Now that we have that understanding, how do we recall the muscle memory for bowling? This is where Pinqueen2000 nailed the key. By performing a repeated series of motions just prior to bowling (a pre-shot routine), you provide a "cue" to your sunconscious mind that it is about to recall the part of the brain controlling the neural pathways to perform the athletic motion of bowling. Establish a good pre-shot routine (include a deep breath).
So what's happening in the 10th frame? Muscle memory (the subconcious mind) is easily over-riden by the conscious mind...in essence, it takes just a mere thought to interfere with muscle memory requiring the conscious mind to control whatever part of your body you are concentrating on.
I could go on-and-on, but I think you've got enought ot think about. The best phrase I can advise you to recall in the 10th frame comes from the Team USA Head Coach, Fred Borden: "QUIET THE MIND, TRUST THE BODY". Then get through your pre-shot routine, take deep breath, focus on your target and go.
Sorry about being so verbose...I said it was my favorite bowling topic.
