NASM - Flexibility Training Q&A 2024
Active-isolated stretching uses which mechanism of action? - ANSWER-Reciprocal
inhibition
Define: Altered Reciprocal inhibition - ANSWER-The concept of muscle inhibition,
caused by a tight agonist, which inhibits its functional antagonist.
Define: Arthrokinetic Dysfunction - ANSWER-altered forces at the join that result in
abnormal muscular activity and impaired neuromuscular communication at the joint
Define: Autogenic inhibition - ANSWER-The process by which neural impulses that
sense tension are greater than the impulses that cause muscles to contract, providing
an inhibitory effect to the muscle spindles
Define: Neuromuscular Efficiency - ANSWER-The ability of the neuromuscular system
to allow agonists, antagonists, and stabilizers to work synergisticilly to produce, reduce,
and dynamically stabilize the entire kinetic chain in all three plains of motion
Define: Pattern overload - ANSWER-Consistantly repeating the same pattern of motion,
which may place abnormal stresses on the body
Define: Postural Distortion Patterns - ANSWER-Predictable patterns of muscle
imbalances
Define: Reciprocal inhibition - ANSWER-Simultaneous relaxation of one muscle and the
contraction of its antagonist to allow movement to occur.
Define: Relative flexibility - ANSWER-The tendancy of the body to seek the path of least
resistance during functional movement patterns ( if the muscles are lengthened,
inelastic connective tissue fibers acts as road blocks, preventing the muscle fibers from
moving properly. This causes alterations in normal tissue extensibility and causes
Relative Flexibility)
Define: Synergistic dominance - ANSWER-Occurs when synergists take over as prime
movers due to weak or inhibited prime movers
Dynamic stretching uses which mechanism of action? - ANSWER-Reciprocal inhibition
Give and example of reciprocal inhibition. - ANSWER-During a bicep curl the biceps
contract and as a result of reciprocal inhibition, the tricep head relaxes (the antagonist)
Static stretching uses which mechanism of action? - ANSWER-Autogenic inhibition
and/or reciprocal inhibition (depending on how stretch is performed)
