Chapter 7 Flexibility Terms

Question 1

Reciprocal Inhibition

Answer 1

Simultaneous contraction of one muscle and the relaxation of the antagonist to allow the movement to take place.

Example: Bicep agonist, tricep antagonist

Question 2

Altered Reciprocal Inhibition

Answer 2

Concept of muscle inhibition caused by a tight agonist, which inhibits its functional antagonist.

Example: Tight Psoas (Hip flexor) would decrease neural drive of the glute max (Hip Extensor)

Question 3

Synergistic Dominance

Answer 3

Neuromuscular phenomenon that occurs when inappropriate muscles take over the function of a weak or inhibited prime mover

Essentially when non prime mover muscles compensate to help with the movement.

Question 4

Athrokinetic Dysfunction

Answer 4

Altered Forces at the joint that result in abnormal muscular activity and impaired neuromuscular communication at the joint
