Flexibility Training Concepts Flashcards
Flexibility
The normal extensibility of soft tissues, that allows for full range of motion of a joint
Extensibility
Capability to be elongated, or stretched
Range of motion (ROM)
The degree to which specific joints or body segments can move often measured in degrees
Mobility
Optimal flexibility, and joint range of motion they ability to move freely
Myofascial
The body’s connective tissue that includes muscles and fascia
Relative flexibility
The process in which the body seeks the path of least resistance during functional movements
Human movement system ( HMS)
( Kinetic Chain)
The collective components and structures that work together to move the body:
muscular, skeletal, and nervous system
Soft Tissue
Tissue connecting, supporting and surrounding bodily structures and organs
Postural distortion patterns
Predictable patterns of muscle imbalances
Muscle Imbalance
When muscles on each side of the joint, have Altered Length- tension relationship
Force- couple relationship
The synergistic action of multiple muscles working together to produce movement around a joint
Osteokinematics
Movement of a limb that is visible
Arthrokinematics
The description of a joint surface movement, consist in 3 major types
Roll, slide and spin
Possible causes of Muscle Imbalances
Postural Distortions
Repetitive movement
Cumulative trauma
Emotional stress
Poor training techniques
Poor bodily control
Biased training latterns
Problem of Muscular Imbalances
Reciprocal inhibition
Synergistic dominance
Osteo- arthrokinematic dysfunction
Reciprocal inhibition
When an agonist receive a signal to contract, Its functional antagonist, also received an inhibitory signal, allowing it to lengthen
Altered reciprocal inhibition
Occurs when an over active agonist muscle decrease the neural drive to its functional antagonist
Overactive
When elevated neural drive causes a muscle to be healed in a chronic state of contraction
Under active
When a muscle is experiencing neural inhibition and limited neuro muscular recruitment
Synergistic Dominance
The Neuromuscular phenomenon that occurs when synergist take over function for a weak or inhibited prime mover (agonist)
Altered length tension relationship
When a muscle’s resting length is too short or too long, reducing the amount of force it can produce
Neuromuscular efficiency
The ability of the nervous system to recruit the correct muscles to produce force, reduce force , and dynamically stabilize the body structure in all three planes of motion
Muscle Spindle
Sensory receptors sensitive to change in length of the muscle and the rate of that change
Central Nervous system
A division of the nervous system that includes the brain and the spinal cord
Stretch Reflex
Neurological signal from the muscle spindle that causes a muscle to contract to prevent excessive lengthening
Golgi Tendon Organ ( GTO)
Specialized sensory receptor, located at the point where skeletal muscle fibers insert into the tendons of skeletal muscles sensitive to changes in muscular tension and rate of tension change
Autogenic Inhibition
The process by which neural impulses that sense tension, are greater than the impulses that cause muscles to contract, providing Inhibitory effect to the muscle spindles
Lengthening Reaction
When a muscle is lengthened a cascade of neurological reactions occur that allows the muscle to be stretched
Static Stretching
A type of stretch where the muscles is passively lengthened to the point of tension and held for a sustained amount of time
