Question 1

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

Accepted Answer

Static stretching

Answer

Static stretching requires the athlete to hold a position at the end of the muscle's range of motion without movement, allowing a sustained elongation stimulus.

Question 2

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

Accepted Answer

Golgi tendon organ

Answer

The Golgi tendon organ (GTO) detects tension in the musculotendinous unit and triggers autogenic inhibition, causing the muscle to relax when sufficiently stimulated.

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

Dynamic stretching performed during the warm-up elevates tissue temperature, activates motor patterns, and improves joint ROM without the performance decrements associated with prolonged static stretching.

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

In CR PNF, the target (agonist) muscle is isometrically contracted against resistance for 6–10 seconds; upon relaxation, autogenic inhibition allows a greater passive stretch to be achieved.

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

Mobility implies active, controlled movement through a range of motion, whereas flexibility refers to the passive capacity of soft tissue to allow joint displacement.
