Chapter 7 Flexibility Training Flashcards
Extensibility
Capability to be elongated or stretched
Flexibility
The normal extensibility of all soft tissue that allows full range of motion
Dynamic range of motion
The combination of flexibility and the nervous system’s ability to control this range of motion efficiently
Neuromuscular efficiently
The ability of the neuromuscular system to allow agonist, antagonists, and stabilizers to work synergistically to produce, reduce, and dynamically stabilize the entire kinetic chain in all three planes of motion
Postural distortion patterns
Predictable patterns of muscle imbalances
Relative flexibility
The tendency of the body to seek the path of least resistance during functional movement patterns
Muscle imbalances
Alteration of muscle length surrounding a joint
Reciprocal inhibition
The simultaneous contraction of one muscle and the relaxation if it’s antagonist to allow movement to take place
Altered reciprocal inhibition
The concept of muscle inhibition, caused by a tight agonist, which inhibits it’s functional antagonist
Synergistic dominance
The neuromuscular phenomenon that occurs when inappropriate muscles take over the function of a weak or inhibited prime mover
Arthrokinematics
The motions of joints in the body
Arthrokinetic dysfunction
Altered forces at the joint that result in abnormal muscular activity and impaired neuromuscular communications at the joint
Autogenic inhibition
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
Muscle spindles
Receptors sensitive to change in length of the muscle and the rate of that change
Muscle synergies
Groups of muscles that are recruited by the central nervous system to provide movement
Pattern overload
Consistently repeating the same pattern of motion, which may place abnormal stresses on the body.
Davis’s law
States that soft tissue models along the lines of stress
Length-tension relationship
The resting length of the muscle and the tension the muscle can produce at this resting length
Force-couple
Muscle groups moving together to produce movement around a joint
Rotary motion
Movement of the bones around the joints
Torque
A force that produces rotation
A common unit of torque is newton-meter or Mn
Motor behavior
Motor response to internal and external environment stimuli
Motor control
How the central nervous system intergrates internal and external sensory information with previous experiences to produce a motor response
Motor learning
Integration of motor control processes through practice and experience, leading to a relatively permanent change in the capacity to produce skilled movements
