NASM Corrective Exercise and Flexibility Training 4

Question 1

During an overhead squat assessment, a client's feet turn out. Which muscle is most likely overactive?

Accepted Answer

Lateral gastrocnemius

Answer

NASM lists the soleus, lateral gastrocnemius, and biceps femoris (short head) as overactive when the feet turn out.

Question 2

A client's knees move inward (valgus) during the overhead squat. Which muscle group is most likely underactive?

Accepted Answer

Gluteus medius and gluteus maximus

Answer

Weak gluteus medius and maximus fail to control femoral adduction and internal rotation, which lets the knees cave in.

Question 3

In the Corrective Exercise Continuum, what comes directly after lengthening techniques?

Accepted Answer

Activation techniques

Answer

The continuum runs inhibit, lengthen, activate, integrate, so activation follows lengthening.

Question 4

A tight psoas reduces neural drive to the gluteus maximus. What is this called?

Accepted Answer

Altered reciprocal inhibition

Answer

Altered reciprocal inhibition happens when an overactive agonist reduces neural drive to its functional antagonist.

Question 5

When a weak gluteus maximus leaves the hamstrings to take over hip extension, which concept does this describe?

Accepted Answer

Synergistic dominance

Answer

Synergistic dominance occurs when synergists take over for a weak or inhibited prime mover.
