Flexibility:
normal extensibility of all soft tissues that allow for full range of motion of a joint.
-
extensibility
capability to be elongated or stretched
-
dynamic range of motion
combination of flexibility and the nervous system's ability to control this range of motion efficiently
-
neuromuscular efficiency:
ability of the neuromuscular system to allow agonists, antagonists, and stabilizers to work synergistically to produce, reduce, and dynamically stabilze the entire kinetic chain in all three planes of motion.
-
dynamic functional flexibility:
multiplanar soft tissue extensibility w/ optimal neuromuscular efficiency throughout the full range of motion
-
postural distortion patterns:
predictable patterns of muscle imbalances
-
relative flexibility
tendency of the body to seek the path of least resistance during functional movement patterns.
-
muscle imbalance:
- alteration of muscle length surrounding a joint
- causes: postural stress, emotional duress, repetitive movement, cummaltive trauma, poor technique, lack of core strength, lack of neuromuscular control
-
altered reciprocal inhibition:
concept of muscle inhibition, caused by tight agonist, which inhibits its functional antagonist.
-
synergistic dominance;
neuromuscular phenomenon that occurs when inapporpriate muscles take over the function of a weak or inhibted prime mover
-
arthorkinematics:
the motions of joints in the body
-
arthrokinetic dysfunction:
altered forces at the join taht results in abnormal muscular activity and impaired neuromuscular communicaation at the joint.
-
autogenic inhibition:
process when neural impulses that sense the tension is greater than the impulses that cause muscles to contract providing an inhibitory effect to the muscle spindles.
-
pattern overload:
consistently repeating the same pattern of motion, which may place abnormal stresses on the body.
-
davie's law:
states that soft tissue models along the lines of stress
-
progression of flexibility:
- corrective: foam roll, static stretching
- active flexibility: foam roll, supine straight leg raise
- functional: dynamic stretching (side lunge), foam roll
-
Static stretching:
passively taking a muscle to the point of tension and holding the stretch for a min of 20 seconds.
-
active isolated stretch
using agonists and syngergists to dynamically move the joint into a range of motion
