CSCS Flexibility & Mobility Training

Question 1

Which type of stretching involves holding a muscle at end range for 15–60 seconds without movement?

Accepted Answer

Static stretching

Answer

Dynamic stretching

Answer

Ballistic stretching

Answer

PNF stretching

Question 2

Which proprioceptor is primarily responsible for autogenic inhibition, the mechanism exploited by PNF stretching?

Accepted Answer

Golgi tendon organ

Answer

Muscle spindle

Answer

Ruffini endings

Answer

Pacinian corpuscle

Question 3

Dynamic stretching is most appropriately included during which phase of a training session?

Accepted Answer

Pre-exercise warm-up to prepare joints and muscles for activity

Answer

Post-workout cool-down only

Answer

During rest intervals between heavy sets

Answer

Immediately after static stretching at session end

Question 4

In the contract-relax (CR) PNF technique, what occurs immediately before the assisted passive stretch?

Accepted Answer

The agonist (target) muscle is contracted isometrically for 6–10 seconds then relaxed

Answer

The antagonist muscle is contracted isometrically for 6–10 seconds

Answer

The athlete rapidly bounces at end range to increase tension

Answer

A partner forces the limb beyond passive range of motion

Question 5

Which statement BEST distinguishes mobility from flexibility?

Accepted Answer

Mobility is the active ability to move a joint through its ROM with muscular control; flexibility is the passive ability to achieve that ROM

Answer

Flexibility refers to active joint control; mobility refers to passive tissue length

Answer

Mobility and flexibility are interchangeable terms in strength and conditioning

Answer

Flexibility requires equipment; mobility does not

Question 6

Self-myofascial release (SMR) using a foam roller is thought to acutely improve flexibility primarily by:

Accepted Answer

Reducing neuromuscular excitability and addressing fascial adhesions

Answer

Permanently increasing sarcomere number in the muscle

Answer

Increasing collagen synthesis in surrounding tendons

Answer

Causing micro-tears that rebuild with greater extensibility

Question 7

According to NSCA guidelines, prolonged static stretching (>60 s) performed immediately before exercise is most likely to:

Accepted Answer

Acutely decrease strength, power, and explosive performance

Answer

Increase power output by warming up muscle tissue

Answer

Have no measurable effect on strength or power

Answer

Reduce injury risk during maximal sprint efforts
