Ch 14 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; 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)
The collective components and structures that work together to move the body: muscular, skeletal, and nervous systems.
Soft tissue
Tissue connecting, supporting, and surrounding bodily structures and organs
Which portion of a client’s exercise program should be designedfirst?
The flexibility portion
Postural distortion patterns
Predictable patterns of muscle imbalances.
Muscle imbalance
When muscles on each side of a joint have altered length-tension relationships.
Force-couple relationships
The synergistic action of multiple muscles working together to produce movement around a joint.
Osteokinematic
Movement of a limb that is visible.
Arthrokinematics
The description of joint surface movement; consists of three major types: roll, slide, and spin.
Reciprocal inhibition
When an agonist receives a signal to contract, its functional antagonist also receives an inhibitory signal allowing it to lengthen.
Altered reciprocal inhibition
Occurs when an overactive agonist muscle decreases the neural drive to its functional antagonist.
Overactive
When elevated neural drive causes a muscle to be held in a chronic state of contraction.
Underactive
When a muscle is experiencing neural inhibition and limited neuromuscular recruitment.
Synergistic dominance
The neuromuscular phenomenon that occurs when synergists take over function for a weak or inhibited prime mover (agonist).
There are three major arthrokinematic joint motions. What are they?
roll, slide, and glide
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’s structure in all three planes of motion.
