Stabilization Chain* Intention/Direction Muscles
*(not pictured: transverse abdominus)
The triceps keep the embrace taut.
The shoulder external rotators stabilize the shoulder joint which stabilizes the connection between embrace and body.
The transverse abdominus stabilizes the spine.
The piriformis stabilizes the hip joint, the relationship between the leg and the spine.
The supraspinatus adducts the arm associated with the obliques showing direction lateral to the Mark.
The deltoid stabilizes the embrace when the partners are moving in the same direction.
Co-contraction is simultaneous contraction of paired muscles. Co-contraction of the hamstrings (biceps femoris) and quadriceps is used to create extra power and stability, elasticity (rebote), and to send extra power through the revel’s body to send the leg into the air (voleo gancho) or to create a contra block (patada, rebote cadera).
In blocking contra movements we use co-contraction of biceps and triceps.
We also use co-contraction of these muscle pairs to intensify the arch to support off-balance moves, volcada and colgada.
Flexes the hips to show intention toward and away from the Mark. For the Revel, the Psoas prepares the base leg for all projections
