- altered force-couple relationships (altered muscle activation)
- altered arthrokinematics (altered joint motion)
44

45
what is the ultimate goal of the HMS?
to maintain homeostasis (or dynamic postural equilibrium)
46
what can poor flexibility lead to?
the development of relative flexibility (or altered movement patterns)
47
relative flexibility example in the squat
- feet externally rotated
- because most people have tight calf muscles, they lack the proper amount of dorsiflexion at the ankle to perform a squat with proper mechanics
- by widening the stance and externally rotating the feet, it is possible to decrease the amount of dorsiflexion required at the ankle to perform a squat using good technique
48
relative flexibility example in the overhead shoulder press
- excessive lumbar extension (arched lower back)
- individuals who possess a tight latissimus dorsi will have decreased sagittal-plane shoulder flexion (inability to life arms directly overhead), and as a result, they compensate for this lack of range of motion at the shoulder in the lumbar spine to allow them to press the load completely above their head
49
overactive muscle imbalances
forcing compensation to occur
50
underactive muscle imbalances
allowing for the compensation to occur
51
mechanisms that may cause muscle imbalance
- postural stress
- emotional duress
- repetitive movement

- poor training technique
- lack of core strength
- lack of neuromuscular efficiency
52
muscle imbalances may be caused by or result in the following:
- altered reciprocal inhibition
- synergistic dominance
- arthrokinetic dysfunction
- overall decreased neuromuscular control
53
example of reciprocal inhibition in the biceps curl
to perform elbow flexion during the biceps curl, the biceps brachii actively contracts while the triceps brachii (the antagonist muscle) relaxes to allow mvoement to occur
54
example of altered reciprocal inhibition in the hips
a tight psoas (hip flexor) would decrease neural drive of the gluteus maximus (hip extensor)
55
what does altered reciprocal inhibition alter?
force-couple relationships
56
what does altered reciprocal inhibition produce?
synergistic dominance
57
what does altered reciprocal inhibition lead to the development of?
- faulty movement patterns
- poor neuromuscular control
- arthrokinetic (joint) dysfunction
58
example of synergistic dominance in the hips
if the psoas is tight, it leads to altered reciprocal inhibition of the gluteus maximus, which in turn results in increased force output of the synergists for hip extension (hamstring complex, adductor magnus) to compensate for the weakened gluteus maximus
59
result of synergistic dominance
faulty movement patterns, leading to arthrokinetic dysfunction and eventual injury (such as hamstring strains)
60
what can altered joint motion be caused by?
altered length-tension relationships and force-couple relationships, which affect the joint and cause poor movement efficiency
61
performing a squat with excessively externally rotated feet (feet turned outward) forces what to happen?
- forces the tibia (shin bone) and femur (thigh bone) to also rotate externally
- this posture alters the length-tension relationships of the muscles at the knees and hips, putting the gluteus maximus in a shortened position and decreasing its ability to generate force
- the biceps femoris (hamstring muscle) and piriformis (outer hip muscle) becomes synergistically dominant, altering the force-couple relationships and ideal joint motion, increasing the stress on the knees and low back
62
with time, what can happen due to arthrokinetic dysfunction?
the stress associated with it can lead to pain, which can further alter muscle recruitment and joint mechanics
63
neuromuscular efficiency
the ability of the neuromuscular system to properly recruit muscles to produce force (concentrically), reduce force (eccentrically), and dynamically stabilize (isometrically) the entire kinetic chain in all
three planes of motion
64
what helps to determine muscle balance or imbalance?
mechanoreceptors (or sensory receptors)
65
what do mechanoreceptors include?
the muscle spindles and Golgi tendon organs
66
muscle spindles
the major sensory organ of the muscle
67
what are muscle spindles composed of?
microscopic fibers that lie parallel to the muscle fiber
68
what are muscle spindles sensitive to?
- change in muscle length
| - rate of length change
69
what is the function of the muscle spindle?
to help prevent muscles from stretching too far or too fast
70
what happens when a muscle on one side of a joint is lengthened (because of a shortened muscle on the opposite side)?
- the spindles of the lengthened muscle are stretched
- this information is transmitting to the brain and spinal cord, exciting the muscle spindle and causing muscle fibers of the lengthened muscle to contract
- this often results in micro muscle spasms or a feeling of tightness
71
example - hamstring complex when the pelvis is rotated anteriorly
- the anterior superior iliac spines move downward and the ischium moves upward
- if the attachment of the hamstring complex is moved superiorly, it increases the distance between the two attachment sites and lengthens the hamstring complex
- in this case, the hamstring complex does not need to be statically stretched because it is already in a stretched position
- when a lengthened muscle is stretched, it increases the excitement of the muscle spindles and further creates a contraction (spasm) response
- with this scenario, the shortened hip flexors are helping to create the anterior pelvic rotation that is causing the lengthening of the hamstring complex
- instead, the hip flexors need to be stretched
72
example - knees adduct and internally rotate during a squat exercise
- the underactive muscle is the gluteus medius (hip abductor and external rotator), and the overactive muscles include the adductors (inner thighs) and tensor fascia latae (a hip flexor and hip internal rotator)
- thus, one would not need to stretch the gluteus medius, but instead stretch the adductor complex and tensor fascia latae, which in this case are overactive, pulling the femur into excessive adduction and internal rotation
73
where are Golgi tendon organs located?
within the musculotendinous junction (or the point where the muscle and the tendon meet)
74
what are Golgi tendon organs sensitive to?
- changes in muscular tension
| - the rate of tension change
75
what does the Golgi tendon organ do when a muscle is excited?
it causes the muscle to relax, which prevents the muscle from being placed under excessive stress, which could result in injury
76
what does prolonged Golgi tendon organ stimulation provide?
-an inhibitory action (called autogenic inhibition) to muscle spindles (located within the same muscle)
77
what does holding a stretch do?
- creates tension in the muscle
- this tension stimulates the Golgi tendon organ, which overrides muscle spindle activity in the muscle being stretched, causing relaxation in the overactive muscle and allowing for optimal lengthening of the tissue
78
how long should a stretch be held?
long enough for the Golgi tendon organ to override the signal from the muscle spindle (approximately 30 seconds)
79
reasons for flexibility training
- correcting muscle imbalances
- increasing joint range of motion
- decreasing the excessive tension of muscles
- relieving joint stress
- improving the extensibility of the musculotendinous junction

- a repetitive occupation lifting and loading packages all day
- sitting for long periods of time while working on a computer
82
what do poor posture and repetitive movements result in?
- dysfunction within the connective tissues of the body
- this dysfunction is treated by the body as an injury, and as a result, the body will initiate a repair process termed the cumulative injury cycle
83
cumulative injury cycle
tissue trauma > inflammation > muscle spasm > adhesions > altered neuromuscular control > muscle imbalance
84
what does trauma to the tissue of the body create?
inflammation
85
how does the body respond to inflammation?
it activates the body's pain receptors and initiates a protective mechanism, increasing muscle tension or causing muscle spasm
86
what happens as a result of heightened activity of muscle spindles?
a microspasm
87
what happens as a result of a microspasm?
adhesions (or knots) begin to form in the soft tissue
88
what do adhesions in the soft tissue form?
a weak, inelastic matrix (inability to stretch) that decreases normal elasticity
89
what do adhesions in the soft tissue result in?

- altered force-couple relationships
- altered arthokinetic dysfunction
90
what do altered length-tension relationships lead to?
altered reciprocal inhibition
91
what do altered force-couple relationships lead to?
altered force-couple relationships
92
what does arthrokinetic dysfunction lead to?
altered joint motion
93
what happens if these adhesions are left untreated?
they can begin to form permanent structural changes in the soft tissue that is evident by Davis's law
94
what is is soft tissue remodeled with?
an inelastic collagen matrix that forms in a random fashion, meaning it usually does not run
95
what happens to these inelastic connective tissue fibers when the muscle fibers are lengthened?
they act as road blocks, preventing the muscle fibers from moving properly, which creates alterations in normal tissue extensibility and causes relative flexibility
96
what happens if a muscle is in a constant shortened state?
it will demonstrate poor neuromuscular efficiency, which will affect joint motion and alter movement patterns
97
what happens when a muscle is consistently short and moves in a pattern different from its intended function?
the newly formed inelastic connective tissue forms along this altered pattern, reducing the ability of the muscle to extend and move in its proper manner
