Question 1

Which muscle is most commonly overactive and contributing to anterior pelvic tilt?

Accepted Answer

Hip flexor complex (iliopsoas)

Answer

The hip flexor complex, particularly the iliopsoas, is commonly overactive and pulls the pelvis anteriorly, contributing to anterior pelvic tilt.

Question 2

During a single-leg squat assessment, excessive knee valgus is primarily associated with weakness in which muscle?

Accepted Answer

Gluteus medius

Answer

Gluteus medius weakness fails to stabilize the hip in the frontal plane, allowing the femur to adduct and internally rotate, causing knee valgus.

Question 3

Which flexibility technique uses the principle of autogenic inhibition to relax a tight muscle?

Accepted Answer

Self-myofascial release

Answer

Self-myofascial release (foam rolling) applies sustained pressure to stimulate the Golgi tendon organ, triggering autogenic inhibition and muscle relaxation.

Question 4

What is the recommended hold time for static stretching of an overactive muscle in corrective exercise programming?

Accepted Answer

20–30 seconds

Answer

Static stretches should be held for 20–30 seconds to allow the Golgi tendon organ to facilitate sufficient muscle relaxation.

Question 5

In the NASM Corrective Exercise Continuum, which phase immediately follows inhibitory techniques?

Accepted Answer

Lengthening

Answer

The four-phase continuum progresses from Inhibit → Lengthen → Activate → Integrate, so lengthening techniques follow inhibitory work.
