Flexibility Training Flashcards
Capability to be elongated or stretched.
Extensibility
The normal extensibility of all soft tissues that allows the full range of motion of a joint.
Flexibility
The combination of flexibility and the nervous systems ability to control this range of motion efficiently.
Dynamic range of motion
The ability of the neuromuscular system to allow agonists, antagonists, and stabilizers to work synergistically to produce, reduce, and dynamically stabilize the entire kinetic chain in all three planes of motion.
Neuromuscular efficiency
Predictable patterns of muscle imbalances
Postural distortion patterns
The tendency of the body to seek the path of least resistance during functional movement patterns.
Relative flexibility
Alteration of muscle length surrounding a joint
Muscle imbalances
The simultaneous relaxation of one muscle and the contraction of its antagonist to allow movement to take place.
Reciprocal inhibition
The concept of muscle inhibition, caused by a tight agonist, which inhibits it functional antagonist
Altered reciprocal inhibition
The neuromuscular phenomenon that occurs when inappropriate muscles take over the function of a weak or inhibited prime mover.
Synergistic dominance
The motions of joints in the body
Arthrokinematics
Altered forces at the joint that result in abnormal muscular activity and impaired neuromuscular communication at the joint.
Arthrokinetic dysfunction
Helps prevent muscle from stretching too far too fast.
Muscle spindles
What can cause a feeling of tightness when the muscle isn’t actually tight?
When a muscle on one side of a joint is lengthened (bc of a shortened muscle on the opposite side), the muscle spindles of the lengthened muscle are stretched. This info is transmitted to the brain, exciting the muscle spindle and causing the muscle fibers of the lengthened muscle to contract.
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.
Autogenic inhibition
