NASM Core and Balance Training

Question 1

Which muscle is considered a primary component of the local (inner unit) core stabilization system?

Accepted Answer

Transversus abdominis

Answer

The local stabilizers include the transversus abdominis, multifidus, internal obliques, pelvic floor muscles and diaphragm. They provide segmental spinal stability.

Question 2

What is the purpose of the drawing-in maneuver?

Accepted Answer

To activate the transversus abdominis and improve spinal stabilization

Answer

The drawing-in maneuver pulls the navel toward the spine. It recruits the transversus abdominis and other local stabilizers, preparing the core for movement.

Question 3

What is the correct progression of core training in the OPT model?

Accepted Answer

Stabilization, strength, power

Answer

Clients begin with core stabilization exercises, progress to core strength (full range of motion, dynamic movement), then to core power (rapid, explosive movements).

Question 4

Proprioception is best described as:

Accepted Answer

The body's cumulative sensory input from mechanoreceptors that informs body position and movement

Answer

Proprioception is the cumulative sensory input to the central nervous system from mechanoreceptors in joints, muscles and tendons. It allows awareness of body position and movement, and it improves with balance training.

Question 5

Which is the most appropriate way to progress a balance exercise for a client who has mastered a single-leg stance on a stable surface?

Accepted Answer

Move to an unstable surface such as a foam pad or balance disc

Answer

Balance progressions move from stable to unstable surfaces and add reaching or other challenges, while the client maintains control. Safety is kept intact by increasing difficulty gradually.
