Flexibility
Ability to move a joint through its complete rang of motion (ROM)
-
Extensibility
Capability to be elongated or stretched
-
Dynamic ROM
- Combination of flexibility and nervous system's ability to control this ROM efficiently.
- Optimal control of movement through a joint's entire ROM
-
Neuromuscular Efficiency
Ability of the nervous system to recruit correct muscle (antagonists, synergists, stabilizers) to produce force (concentrically), reduce force (eccentrically), and dynamically stabilize (isometrically) the body's structure in all 3 planes of motion.
-
Postural Distortion Patterns
Predictable patterns of muscle imbalances
-
Relative Fleibility
The tendency of the body to seek the path of least resistance during functional movement patterns
-
Muscle imbalance
Alteration of muscle length surrounding a given joint
-
Reciprocal Inhibition
The simultaneous relaxation of one muscle and the contraction of its antagonist
-
Altered Reciprocal Inhibition
Caused by a tight agonist muscle decreasing neural drive to its functional antagonist.
-
Synergistic Dominence
Neuromuscular phenomenon when synergists take over function for a weak inhibited prime mover.
-
Arthrokinematics
The motions of joints in the body
-
Arthrokinetic dysfunction
Biomechanical and neuromuscular dysfunction leading to altered join motion
-
Autogenic Inhibition
The process by which neural impulses that sense tension are greater than the impulses that cause the muscle to contract, providing an inhibitory effect to the muscle spindles.
-
Pattern Overload
Consistently repeating the same pattern of motion, which may places abnormal stresses on the body.
-
Davi's Law
States that soft tissue models along the lines of stress
-
What are the 3 phases of flexibility?
- Corrective
- Active
- Functional
-
What is Corrective flexibility's objective, and how is it gone about?
- Objective: Increase joint ROM, improve muscle imbalances, correct altered joint motion
- How: SMR and static stretching
-
What is Active flexibility's objective, and how is it gone about?
- Objective: Improve the extensibility of soft tissue and increase neuromuscular efficiency by using reciprocal inhibition
- How: SMR and active isolates stretching
-
What is Funtional flexibility's objective, and how is it gone about?
- Objective: increase flexibility with optimal neuromuscular control
- How: SMR and dynamic stretching
