06 - Core Training Concepts Flashcards
What is the core?
Section of the body defined by the structures that make up the LPHC.
What is core stability?
LPHC stability comprised of local or inter-segmental stability (Local Stabilization System), global stability (Global Stabilization Sys- tem), and global mobility.
What muscles make up the majority of the core (muscle subsystem)?
LPHC: lumbo-pelvic-hip complex
What are the two methods of providing core and spine stability?
bracing and drawing in
What is bracing? What muscle subsystem and specific muscles are used?
Contracting the global muscle system (superficial) using the external, internal and quadratus lumborum muscles to increase LPHC stiffness and stability.
What is drawing in? What muscle subsystem and specific muscles are used?
Contracting the local muscle system (deep) using the multifidus and transverse abdominus muscles to increase inter-vertebral stiffness and stability.
What core muscles are in the global muscle system?
Transversus
Rectus Abdominis
Internal Oblique

What type of muscle fibers are muscles in the local muscle system?
slow twitch \ type I
What type of muscle fibers are muscles in the global muscle system?
fast twitch \ type II
What are the main functions of the local stabilization system?
Muscles that attach directly to the spine. These muscles are primarily responsible for inter-vertebral and inter-segmental stability, working to limit excessive compressive, shear, and rotational forces between spinal segments.
What are the main functions of the global stabilization system?
Muscles that attach to from the pelvis to the spine. These muscles act to transfer loads between the upper extremity and lower extremity and provide stability between the pelvis and spin. Muscles provide stabilization and eccentric control of the core during functional movements.
What are the main functions of the movement system?
The movement system includes muscles that attach the spine and/or pelvis to the extremities. These muscles are primarily responsible for concentric force production and eccentric deceleration during dynamic activities.
The core (LPHC) is stabilized during functional movement by two primary systems:
thoracolumbar stabilization mechanism and the intra-abdominal pressure (IAP) stabilization mechanism
What is the thoracolumbar fascia (TLF)?
The TLF is a fascial network of non-contractile tissue that plays an essential role in the functional stability of the core. The TLF is divided into the posterior, anterior, and middle layers
What is the gray tissue in the middle low back called?
thoracolumbar fascia (TLF)
How is the thoracolumbar fascia (TLF) used by the body?
it can be engaged dynamically because of the contractile tissue that attaches to it. The muscles that attach to the TLF include the deep erector spinae, multifidus, transversus abdominis, internal oblique, gluteus maximus, latissimus dorsi, and quadratus lumborum.31 The transversus abdominis and the internal oblique are particularly important for stabilization. They attach to the middle layer of the TLF via the lateral raphe. Activation of both obliques creates a traction and tension force on the TLF, enhancing the regional inter-segmental stability and decreasing translational and rotational stress of the core
How does intra-abdominal pressure work?
Increased IAP decreases compressive forces in the spine. The abdominal muscles contract against the viscera, pushing the viscera superiorly into the diaphragm and inferiorly into the pelvic floor.
What are some benefits for core training?
reduced injury rate with proper bracing and better movement quality, balance, function, performance control, power production, posture and reduce pain.
Local core stabilizers attach to?
Muscles that attach directly to the vertebrae.
