Joint cavitations
The sound a joint makes when manipulated (the pop/crack)
Does a joint always have to cavitate to be effective?
Nope
Open kinetic chain origin is __________ and muscle contraction produces movement at the _________________.
fixed, insertion
Manips goals
decrease pain
increase ROM
Closed kinetic chain the _____________ is fixed and the muscle acts to move the ____________
insertion, origin
Shoulder flexion ROM
170
SHoulder extenstion ROM
60
Shoulder abduction ROM
180
Shoulder medial rotation ROM
90
Shoulder lateral rotation ROM
90
Elbow Flexion ROM
160
Wrist Flexion ROM
90
Wrist extension ROM
70

20
Ulnar ROM
45
Plyometrics attempts to combine ___________ of movement with ______________.
speed, strength
Plyometrics defined
a series of quick powerful exercises that involve pre-stretching and activating the stretch-shortening cycle to produce subsequently stringer concentric contraction,
Rubber band analogy
When stretch is applied, potential energy is stored and applied as it returns to its original length when the stretch is released
Plyometrics biomechanics
goal is to reduce time required between eccentric muscle contraction and the initiation od concentric contraction
PLyometrics progression
- in place jumping
- standing jumps
- multi response jumps
- bounding
- high stress sport specific
PLyometrics guidelines
- specific
- quality over quantity
- greater intensity = more recovery
- fatigue
- proper technique
- no more then 3x a week
- dynamic testing
Anterior Talus glide (pronation) =
more plantar flexion
Posterior talus glide (supine) =
more dorsiflexion
