types of flexibility training and programming strategies Flashcards
____, _____, ____ can be used to directly evaluate joint ROM
goniometer, inclinometer, flexometer
indirect measures of ROM are often obtained using
recorded observations of movement capabilities (movement screen) or assistive devices
assessments that employ cross-joint movements can be very useful, examples
apley back scratch test
single straight leg raise
thomas test
trunk flex/ext. test
OH squat
goal of flexibility training
attain chronic adjustments in tissue lengthening abilities using progressively-applied stretching techniques
active stretching
involves the use of force produced by the client to apply a stretch
passive stretching
involves the use of an external force such as a partner, gravity, or stretching device to apply a stretch to a flaccid body segment
static flexibility includes
active stretching
active-assisted stretching
PNF
active-isolation stretching
dynamic flexibility includes
dynamic-performance stretching
slow speed dynamic stretching
ballistic stretching
static stretching
lengthens the muscle in a slow, controlled manner to its terminal ROM
static stretching avoids the
stretch reflex
stretch reflex
reflexive contraction of muscle induced by a rapid stretch; triggered by excitation of muscle spindles and a subsequent feedback loop
static stretching ideally performed at
end
active assisted stretching
builds upon a static stretch with added external force to increase the ROM
partner, towel, band, etc.
active assisted stretching: caution must be taken to avoid
overstretching
active isolation
combines active stretching and neural factors
active isolation step 1: client actively reaches full ROM by
contracting the antagonist of the stretched muscle
active isolation step 2: upon full ROM, the trainer ____ and the client ____
holds the limb, relaxes
active isolation step 3: while stabilized by the trainer the client contracts the _____ again ot increase the stretch
antagonist
active isolation step 4: the contraction is released and then _____ is applied
passive stretch
PNF stretches
used in rehab settings and have gained popularity in fitness due to its marked effects
based on autogenic inhibition induced by GTOs
basic PNF technique
- 10 sec passive stretch through a full ROM is performed directly followed by active-assisted pressure from the trainer
- the client must resist the trainer by contracting the stretched muscle for 6 sec in the terminal position
- the client relaxes, and the trainer holds the joint in the end position for a further 30-sec passive stretch
contract-relax PNF technique
- mimics the protocol of the basic technique except during the last step
- the client simultaneously contracts the opposing muscle group further push the limb in the direction of the stretch rather than just experience a 30-sec passive stretch
dynamic stretching
activities are performed through a full ROM via controlled muscular contractions; often used for movement prep or during a warm-up
dynamic stretches allow
ROM gains related to specific movements employed during training
