The muscle-bone concept presented in most of our standard anatomical descriptions gives a purely mechanical model of movement where levers and other things tend to exist. But in reality, there is a seamless picture of integration that is viewed in the living body.
What moves joints is not just a muscle and bone concept. It is mass. It is momentum. It is gravity. It is ground reaction force. The body takes advantage of these things in a very seamless, integrated and coordinated way. So when one part of the body moves, the whole body responds.
Functionally, the best tissue that can mediate this responsiveness is the connective tissue – the fascia. It keeps everything together and it’s not an inert tissue. It stretches. It rebounds like an elastic band. It contributes to shape stability. It allows us to be more athletic. It helps us be more stable at joints so we can be healthier. It is a contributor to overall well-being and performance.
