14: Flexibility Training Concepts Flashcards
Define Flexibility:
Normal extensibility of soft tissues that allows for full ROM of a joint
Define Extensibility:
Capability to be elongated or stretched
________: the degree to which specific joints or body segments can move, often measured in degrees
Range of Motion
________: optimal flexibility and joint ROM; abiltiy to move freely
Mobility
flexibility + joint ROM
Define Myofacial:
body’s connective tissue that includes muscles and fascia
_____ _____: Process in which body seeks the path of least resistance during fxnal movements (i.e. squat w/ feet turned out excessively due to limited ankle ROM, shoulder press w/ lumbar arched due to ltd lat extensibility)
Relative Flexibility
What 3 systems make up the HMS?
Muscular
Skeletal
Nervous
Define Soft tissue:
Tissue connecting, supporting, and surrounding bodily structures and organs
_____ _____ patterns: Predictable patterns of muscle imbalances (i.e. poor posture–improper mvmt– injury
Postural Distortion
This is when muscles on each side of a joint have altered length-tension relationships
Muscle Imbalances
This is the synergistic action of multiple muscles working together to produce mvmt around a joint
Force-couple Relationships
List some causes of Muscle Imbalances:
postural distortions repetitive movement cumulative trauma emotional duress poor training techcnique poor bodily control biased training patterns
Define Reciprocal inhibition:
agonist/antagonist relationship to allow muscles to lengthen
i.e. bicep-tricep
Define Altered Reciprocal Inhibition:
Occurs when an overactive agonist muscle decreases neural drive to its fxnal anatagonist
Define Overactive:
elevated neural drive causes a muscle to be held in a chronic state of contraction
(Altered Reciprocal Inhibiton)
Define Underactive:
muscle experiences neural inhibition and ltd muscle recruitment
(Altered Reciprocal Inhibition)
Define Synergistic Dominance:
neural muscular phenomenon that occurs when synergists take over fxn for a weak or inhibited prime mover (agonist)
Explain the effects of Altered Reciprocal Inhibition
Altered R.I. chagnes force-couple relationships, produces synergistic dominance, and leads to dvlpmnt of faulty mvmt patterns, poor bodily control, and joint dysfxn
T/F
the antagonist is the prime mover
False!
Agonist
Define Altered Length-tension Relationship:
When a muscle’s resting length is too short or too long, reducing the amount of force it can produce
_____ _____: ability of the NS to recruit correct muscles to produce force, reduce force, and dynamically stabilize the body’s structure in all 3 planes of motion
Neuromuscular Efficiency
_____ _____: prolonged GTO stimulation that overrides/inhibits muscle spindles; causing muscle to relax and allow for optimal lengthening
(why holding stretches long enough is important)
Autogenic Inhibition
Define Lengthening Reaction:
neurological cascade of rxns that occur when a muscle is lengthened and allows it to be stretched
What reaction do you commonly see in static stretching?
Lengthening reaction
