Chapter 9 - Core Training Concepts Flashcards
What is the objective of core training?
To uniformly strengthen the deep and superficial muscles that stabilize, align, and move the trunk of the body, especially the abdominals and muscles of the back.
What are the 3 systems of the core musculature?
Local stabilization system
Global stabilization system
Movement system
What is the core?
The structures that make up the limbo-pelvic-hip complex (LPHC) including the lumbar spine, the pelvic girdle, abdomen, and the hip joint.
Where do the muscles of the local stabilization system attach?
Muscles that attach directly to the vertebrae.
What are the muscles included in the local stabilization system?
Transverse abdominis
Internal obliques
Multifidus
Pelvic floor musculature
Diaphragm
What is the main type of muscle fibers in the local stabilization system? Why?
- Slow-twitch with high-density of muscle spindles
- Constantly using these muscles for stability and limit excessive compression, shear, and rotational forces between spine segments.
Where do the muscles of the global stabilization system attach?
Muscles attach from the pelvis to the spine
What are the muscles included in the global stabilization system?
Quadratus Lumborum
Psoas Major
External Obliques
Portions of the Internal Oblique
Rectus Abdominis
Gluteus Medius
Adductor Complex
What is the purpose of the global stabilization system?
- Act to transfer loads between the upper extremity and the lower extremity.
- Provide stability between pelvis and spine
- Provide stabilization and eccentric control of the core during functional movements.
Where do the muscles of the movement system attach?
Muscles attach the spine and/or pelvis to the extremities.
What are the muscles included in the movement system?
Lattissimus Dorsi
Hip Flexors
Hamstring Complex
Quadriceps
What is the purpose of the movement system?
Responsible for concentric force production and eccentric deceleration during dynamic activities.
What does synergistic interdependent functioning mean? How does it relate to the core musculature (3 systems)?
- Systems work best together rather than separately.
- Collectively all muscles within each system provide dynamic stabilization and neuromuscular control of the entire core (LPHC).
What is the best progression within the three systems for training the core musculature? Why (use house analogy)?
- Local stabilization system
- Global stabilization system
- Movement system
What is the result if movement system of the core is strong and the local stabilization system is weak?
The kinetic chain sense imbalance and forces are not transferred or use properly resulting in compensation, synergistic dominance, and inefficient movements.
