NASM-CPT Special Populations and Flexibility Training 5

Question 1

Holding a static stretch for about 30 seconds causes the muscle to relax primarily through which receptor?

Accepted Answer

Golgi tendon organ

Answer

Sustained tension stimulates the Golgi tendon organ, which inhibits the muscle spindle (autogenic inhibition).

Question 2

Active-isolated stretching relies on contracting the agonist to relax the antagonist being stretched. What is this principle called?

Accepted Answer

Reciprocal inhibition

Answer

Reciprocal inhibition is the simultaneous contraction of one muscle and relaxation of its opposing muscle.

Question 3

A client with tight calves turns their feet out during a squat to avoid limited dorsiflexion. Which concept does this demonstrate?

Accepted Answer

Relative flexibility

Answer

Relative flexibility is the body's tendency to seek the path of least resistance during functional movement.

Question 4

Which exercise positions are generally most appropriate for clients with obesity?

Accepted Answer

Standing or seated exercises

Answer

Standing or seated exercises avoid the discomfort and difficulty of getting up and down from the floor.

Question 5

A client with coronary heart disease takes beta-blockers. How should exercise intensity be monitored?

Accepted Answer

Using rating of perceived exertion (RPE)

Answer

Beta-blockers blunt heart rate response, so RPE gives a more reliable measure of intensity.
