3. Crawling helps activate important muscular and fascial slings that are essential for dynamic stability
While many people are now aware of the deepest core stabilisers, many are unaware of the essential muscular slings and fascial lines that actually provide stability with movement. Many people have a model of the body that includes each of the separate muscles. In reality, muscles work together in slings and coupled movements to create optimal and effective movement.
There are 3 main muscular slings that help us move around efficiently.
The Anterior Oblique Sling includes the inner thigh muscles (Adductors) and the External Oblique on the opposite side. This is one of the main connections that is developed when a baby/adult/animal moves around on all fours, and is extremely important in normal walking as well as for dancers in supporting the leg when lifted in a developpé or an attitude devant.
The Posterior Oblique Sling includes the Latissimus Dorsi and the Gluteus Maximus and Medius and is very important in normal walking, as well as any work in derrière.
The Lateral Sling comprises of the Gluteus Medius, Gluteus Minimus, TFL and ITB on one side, along with the QL and deep adductors on the opposite side. This sling system gives us stability when standing on one leg.
The Fascial Lines that are deeply connected with these muscular slings are also very important in both developing optimal mobility, and strength without bulk, essential elements for any dancer. There are 12 specific fascial lines or myofacial meridians (according to Tom Myers who developed the Anatomy Trains model). Well developed fascial integrity allows dynamic stability in multiple directions which is obviously essential for a dancer.
