· Muscle length can be increased, purely by thinking about the release you want.
In this post, I am aiming to capture some of the key points about brain-muscle co-ordination that are relevant to Alexander Technique. The relevant science is much deeper than outlined here. Muscle spindles send messages to the brain about the length of the muscle while golgi tendon organs within the tendon that attaches the muscle to bone feeds information to the brain about muscle contraction. Barlow discusses muscle spindles, but not golgi tendon organs. There are many ways to find out more about the science, see for example the Journal of Neurophysiology at http://jn.physiology.org – articles in back issues can be accessed free of charge.
