Show answer and explanations
Answer
A
NASM lists the soleus, lateral gastrocnemius, biceps femoris (short head) and TFL as probable overactive muscles when the feet turn out. Treat this as a hypothesis to confirm with further assessment.
B
The medial hamstrings are listed as underactive in feet turning out; the overactive and underactive roles are swapped.
C
The medial gastrocnemius is underactive in this compensation; it is the lateral head that is listed as overactive.
D
The anterior tibialis is an underactive muscle in excessive forward lean and heels rising, not an overactive contributor to feet turning out.
