  6. Muscles


The core is made up of the lumbo pelvic hip complex. The LPHC is made up of the spine, pelvis, abs and hips. A strong core maintains proper movement through the entire kinetic chain. The core is further divided by stabilization muscles and muscles responsible for movement.

Consisting mostly of type 1 muscle fibers and high muscle spindle density the local stabilization system provides support between vertebrae as well as proprioception and postural control. The primary muscles of the local stabilization system are transverse abdominis, internal obliques, multifidus, pelvic floor muscles and diaphragm.

Additionally the global stabilization system transfers loads between upper and lower extremities. The muscles attach from the pelvic floor to the spine. The global stabilization system is made up of the quadratus lumborum, psoas major, external and internal obliques, rectus abdominis, gluteus medius and adductor complex.

The movement system generates force and slows things down. It is made up of the muscles that connect everything together. Those muscles are the lats, hip flexors, hamstrings and adductors. Proper movement requires stabilization. Not having a strong and stable core creates imbalances and in-efficient transfer of energy.
