Study Notes
Global Dynamic Muscles
- Primary function is to produce movement and generate force during physical activities.
- Comprised of muscles that work together for dynamic and coordinated movement patterns.
Intra-abdominal Pressure
- The transverse abdominis is responsible for creating intra-abdominal pressure to support the spine from within.
Diaphragm Role
- Main responsibility of the diaphragm is to regulate breathing and assist in core stability during inhalation and exhalation.
Quadratus Lumborum
- Primary role includes stabilizing the pelvis and lumbar spine, facilitating lateral flexion of the spine.
Spinal Erector Muscles
- Muscle group responsible for spinal extension, lateral flexion, and maintaining an upright position; includes the erector spinae.
Pelvis to Thoracic Cage Muscle
- The multifidus connects the pelvis to the thoracic cage, providing stabilization and aiding in trunk movement.
Core Muscle
- The psoas major is traditionally known as the 'core muscle' and directly attaches to the lumbar vertebrae.
Intersegmental Motion Control
- The multifidus helps control intersegmental motion, adjusting to changes in posture and variations in external load.
Slow-Twitch Fiber Muscle Group
- Local stabilizer muscles, consisting of 'slow-twitch fibers', are responsible for stabilizing the low back and pelvis during static and dynamic activity.
Local Postural Muscles
- Primary responsibility is to maintain posture and stabilize the spine during movement.
Muscle Fiber Types
- Global dynamic muscles possess fast-twitch fibers, designed for quick and powerful movements.
Transverse Abdominis Function
- Primarily helps create intra-abdominal pressure crucial for spinal stabilization and support.
Core Muscular Box Composition
- Muscular box includes the diaphragm, pelvic floor, transversus abdominis, and multifidus, all contributing to core stability.
Core Stability Terminology
- Term commonly used to refer to core stabilization is "lumbar stabilization."
Core Stability Exercises
- Specific exercises mentioned for enhancing core stability include planks, bridges, and rotational movements.
Muscle Pairs for Stabilization
- A total of 31 pairs of muscles contribute to stabilizing the spine, pelvis, and the kinetic chain within the core muscular box.

Description
Learn about core stability exercises, cardiovascular health, muscle strengthening and extensibility techniques, as well as the importance of core muscles in daily activities. Understand the concept of the 'core' as a muscular box consisting of abdominals, paraspinals, gluteals, diaphragm, pelvic floor, and hip girdle.
