Flexibility
|
The normal extensibility of all soft tissues that allow the full range of motion of a joint
|
|
Extensibility
|
Capability to be elongated or stretched
|
|
Dynamic range of motion
|
The combination of flexibility and the nervous system's ability to control this range of motion efficiently
|
|
Neuromuscular efficiency
|
The ability of the neuromuscular system to allow agonists, antagonists, and stabilizers to work synergistically to produce (concentrically), reduce (eccentrically), and dynamically stabilize (isometrically) the entire kinetic chain in all three planes of motion
|
|
Dynamic functional flexibility
|
Multiplanar soft tissue extensibility with optimal neuromuscular efficiency through the full range of motion
|
|
Postural distortion patterns (movement compensations)
|
Predictable patterns of muscle imbalances due to misalignment or malfunction of a link in the kinetic chain leading to decreased neuromuscular efficiency and tissue overload
|
|
Relative flexibility
|
The tendency of the body to seek the path of least resistance during functional movement patterns often due to poor flexibility
|
|
Muscle imbalance
|
Alteration of muscle length surrounding a joint caused by abnormal kinetic chain efficiency (altered length-tension, force-couple, arthrokinematics) in which some are overactive (forcing compensation) and others are underactive (allowing compensation)
|
|
Muscle imbalance causes
|
Altered reciprocal inhibition, synergistic dominance, arthrokinetic dysfunction, and overall decreased neuromuscular control
|
|
Altered reciprocal inhibition
|
Muscle problem caused by a tight agonist, which affects its functional antagonist resulting in muscle imbalances altering length-tension & force-couple relationships and producing synergistic dominance
|
|
Synergistic dominance
|
The neuromuscular phenomenon that occurs when synergists take over the function of (compensate for) a weak or inhibited prime mover leading to joint dysfunction, altered force-couple relationships and decreasing neuromuscular efficiency
|
|
Arthrokinetic dysfunction
|
Altered forces at the joint that result in abnormal muscular activity and impaired neuromuscular communication at the joint
|
|
Arthrokinematics
|
The motions of joints in the body
|
|
Tight muscle results in:
|
Overactive muscle on one side of a joint causes stretching of muscle spindles on other side causing those muscle's fibers to contract resulting in spasms or tightness; stretch the overactive muscle
|
|
Autogenic inhibition
|
The process when neural impulses that sense tension (GTO) is greater than the impulses that cause muscles to contract, providing an inhibitory effect to the muscle spindles; contracting muscle is inhibited by its own receptors causing it to relax and allowing stretching; primary principle in static stretching
|
|
Muscle spindles
|
Major sensory organ in the muscle; microscopic fibers parallel to muscle fibers; sensitive to change of and rate of change of muscle length; excitation causes muscle to contract
|
|
Golgi tendon organ (GTO)
|
Located in musculotendinous junction; sensitive to muscle tension and rate of tension change; excitation causes muscle to relax, preventing excessive stress
|
|
Benefits of flexibility training
|
Corrects muscle imbalance; increases joint ROM; decreases excess muscle tension; relieves joint stress; improves extensibility of musculotendinous junction; maintains normal functional length of all muscles
|
|
Pattern overload
|
Consistently repeating the same type of motion, which may place abnormal stresses on the body; from exercise or normal daily functions
|
|
Cumulative injury cycle
|
Poor posture or repetitive movements (pattern overload) create tissue trauma creating inflammation resulting in muscle spasm causing adhesions which alter neuromuscular control causing muscle imbalance causing more trauma
|
|
Adhesions
|
Knots in muscle soft tissue caused by microspasms due to inflammation from repetitive use or trauma; inelastic matrix reduces stretching ability of muscle; like scar tissue except crosses from one tissue to another
|
|
Davis' law
|
Soft tissue remodels (rebuilds) itself with an inelastic collagen matrix (adhesion) in a random fashion not in the line of the muscle fibers causing relative inflexibility; chronically shortened muscles or lengthened muscles become more so due to these adhesions
|
|
Flexibility continuum
|
Progressive nature of flexibility training- corrective static stretching- active isolated stretching- functional dynamic stretching
|
|
Corrective flexibility
|
Type of flexibility that improves muscle imbalances and altered joint motion using principles of autogenic inhibition; uses SMR & static stretching during stabilization phase of OPT
|
|
Active flexibility
|
This type of flexibility Improves extensibility of soft tissue and increases neuromuscular efficiency by using reciprocal inhibition; uses SMR & an isolated stretching technique; agonists & synergists move limb through full ROM while functional antagonists are stretched; used in strength levels of OPT
|
|
Functional flexibility
|
Integrated multiplanar soft tissue extensibility with optimum neuromuscular control through full ROM; movement without compensations; if compensating, need to regress; uses SMR & dynamic flexibility; power level of OPT
|
|
Self-Myofacial Release (SMR)
|
Stretching technique that focuses on neural and fascial systems; applying gentle force to adhesions alters muscle fibers from bundled to straighter alignment with direction of muscle; stimulates GTO creating autogenic inhibition decreasing muscle spindle excitation releasing hypertonicity of muscle
|
|
Static stretching
|
Passively taking a muscle to the point of tension and holding the stretch for a minimum of 20 seconds & 1-3 sets; uses autogenic inhibition allowing muscle to relax and stretch; contracting antagonist while stretching may reciprocally inhibit the muscle stretched allowing greater lengthening
|
|
Active-isolated stretching
|
Using agonists and synergists to dynamically move the joint into a range of motion; increases motor-neuron excitability creating reciprocal inhibition of the muscle being stretched; pre-activity warmup; hold 1-2 sec for 5-10 reps & 1-2 sets
|
|
Dynamic stretching
|
Active extension of a muscle using force production and momentum to move the joint through the full available ROM; pre-activity warmup of 1 set of 10 reps using 3-10 stretches
