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
_____ _____: repeating poor patterns over time, leading to dyfunction or injury
Pattern Overload
What are 2 potential factors that support the need to impliment flexibility training
Pattern Overload
Cumulitive Injury Cycle
Define Cumulative Injury Cycle
Chain rxn of injury leading to more injury
_____: pain receptors located in the skin and fascial connective tissues (connect muscles)
Nociceptors
This law states that soft tissue models along the lines of stress?
Davis’ Law
______ _____: complex meshwork of connective tissue, including collagen proteins
Collagen Matrix
This system is a web of conneting fibers made of connective tissues that are found just under the skin?
Fascial System
___effect means having a physical effect:
Mechanical
_______ effect means having an effect on the nervous system:
neurophysiological
define DOMS:
delayed onset muscle soreness
felt 24-72 hours after
any medical conditions that could be potentially unsafe for a client:
medical precautions
define contraindications:
specific situations where medication, procedure, or exercise should be avoided
define stretch tolerance:
the ability to experience physical sensations of stretching to reduce the discomfort felt at the end ROM
Define Active Stretching:
Stretching that uses agonists and synergysts to dynamically move the joint into a range of motion
(1-2 second hold, repeating for 5-10 reps)
Define Dynamic Stretching:
Stretching that uses the force production of a muscle and the body’s momentum to take a joint through the full available range of motion
Define Controversial Stretches and examples:
Stretches that have potential for injury risk
- Inverted Hurdler’s Stretch
- Plow
- Shoulder Stand
- Straight-Leg Toe Touch
- Arching Quadriceps
