SBC Core Anatomy and Physiology

Question 1

Which muscle group forms the primary stabilizing core and is most targeted during stability ball exercises?

Accepted Answer

Transverse abdominis

Answer

The transverse abdominis is the deepest abdominal muscle and serves as the primary core stabilizer activated during stability ball work.

Question 2

What term describes the ability of the core muscles to maintain spinal alignment under load?

Accepted Answer

Core stiffness

Answer

Core stiffness refers to the co-contraction of trunk muscles that resists unwanted spinal movement during stability ball exercises.

Question 3

Which spinal region is most protected by engaging the multifidus during stability ball training?

Accepted Answer

Lumbar spine

Answer

The multifidus attaches along the lumbar vertebrae and plays a critical role in protecting and stabilizing the lower back.

Question 4

The erector spinae muscle group runs along which aspect of the vertebral column?

Accepted Answer

Posterior

Answer

The erector spinae run along the posterior (back) side of the vertebral column, providing extension and lateral flexion of the spine.

Question 5

What role do the oblique muscles play during rotational stability ball movements?

Accepted Answer

Spinal rotation and lateral flexion

Answer

The internal and external obliques control spinal rotation and lateral flexion, making them essential for rotational stability ball drills.
