LOGICAL ANALYSIS OF POSTURE: EXPERIMENT THAT MAY CONVINCE YOU THAT SOME MUSCLE FIBRES CAN EXTEND OR ELONGATE
Here is an experiment that may convince you that some muscle fibres can extend or elongate. On the inner surface of the hand, across the wrist just below the palm you will find two lines. Join these lines of both hands together and bring the palms of your hands together as in prayer. You’ll see that the sizes of the fingers (when pressed together) of both hands are normally the same. Both palms of your hands and fingers are normally of the same dimension. Now raise one arm horizontally, take a deep breath in and breathe out slowly, imagining that your fingers are stretching out away from the palms. Imagine that some unknown force is pulling your fingers. Stretch them like this for a few times, reaching out for some mark on the wall. Then join the palms together starting with the lines below the palms and ending with the fingertips. You will notice that the fingers that were ‘instructed’ to stretch are longer than those on the other hand. This may surprise you as it is difficult to imagine that fingers can elongate at will. It does show, however, that muscles can stretch away from the body if the right instructions are given to them from the conscious brain.
