Study Notes
The Importance of Core Stabilization for Neuromuscular Efficiency and Posture
- The core functions as an integrated unit that distributes weight, absorbs force, and transfers ground reaction forces.
- Optimal functioning of the core requires training of the entire kinetic chain in all planes and levels.
- Neuromuscular efficiency is crucial for optimal core functioning and is established through postural alignment and stability strength.
- Dynamic stabilization is critical for neuromuscular efficiency and inefficient stabilization can lead to the body's inability to respond to demands.
- A core stabilization program can improve posture, balance muscles and joints, and enhance communication between muscles and nerves.
- Spinal stabilization is essential for protecting the spine and facilitating balanced muscular functioning of the entire kinetic chain.
- A weak core can lead to decreased force production and efficiency, and improving spinal stabilization enhances neuromuscular control and body positioning.
- Good posture is crucial for optimal core function and helps keep the body strong and prevent injuries.
- Kinetic chain imbalances and low back pain can impact neuromuscular control and lead to arthrogenic muscle inhibition due to altered joint functioning.
- Assessment of core strength, endurance, neuromuscular control, and power is essential to identify imbalances that may exist.
- The Straight Leg Lowering Test can assess core strength, and the Abdominal Neuromuscular Control Test can assess abdominal neuromuscular control.
- The Abdominal Neuromuscular Control Test can identify issues with hip flexors beginning to work as stabilizers, which can increase anterior shear forces and compressive forces at L4-L5, inhibiting transversus abdominis, internal oblique, and multifidus.
