All kinesiology references use illustrations when defining motions, the word descriptions alone are not enough for clear communication.
My reference on kinesiology identifies joints, muscles and motions but does not deal very much with timing and the stretch-shortening cycle.
An interesting question is - when the body is using pre-stretch to shorten muscles, how does it feel? Is there a lack of feeling when using pre-stretch - the 'relaxed arm' 'free energy' that one of the Bryan twins described? Does it feel as if you are not doing that much when using prestretch?
