Chapter 7 Flashcards
what is the term that describes the tendency of the body to seek the path of least resistance during functional movement patterns?
relative flexibility (faulty movement patterns)
what is the capability of soft tissues to be elongated or stretched defined as?
extensibility
during a 40-yrd dash the hamstring complex begins to do most of the work for the weakened gluteus maximus, what term best describes this action?
synergistic dominance
in addition to SMR, which flexibility technique is used for corrective flexibility?
static stretching
what is the phenomenon called when prolonged Golgi tendon organ stimulation provides an inhibitory action to muscle spindles?
autogenic inhibition
what form of stretching should be used to inhibit muscle spindle activity of a tight muscle before and after physical activity?
static stretching
internally rotating the hip during the active kneeling hip flexor stretch places a greater stretch on what muscle?
Psoas
when performing a squat, an overactive hip flexor complex can decrease neural drive to the gluteus maximus, what is this an example of?
altered reciprocal inhibition
what is altered reciprocal inhibition?
when an overactive or tight muscle decreases its neural drive to its functional antagonist (the opposing muscle)
what are the three components of the integrated flexibility continuum?
1 corrective flexibility
2 active flexibility
3 functional flexibility
what is the goal of corrective flexibility and what number is it on the integrated flexibility continuum?
number 1
correct muscle imbalances, increase joint range of motion, correct altered joint motion
what are the two techniques of corrective flexibility?
1 self-myofascial release
2 static stretching
what are the techniques of active flexibility and where is it on the integrated flexibility continuum?
number 2
- self-myofascial release
- self isolated stretching
what are the techniques of functional flexibility and where does it belong on the integrated flexibility continuum?
number 3
- self-myofascial release
- dynamic stretching
what is self-myofascial release?
applying pressure to the knot in the muscle and held for at least 30 seconds. The golgi tendon organ senses the pressure sending signals to and from the brain triggering autogenic inhibition, this causes the muscle to relax.
what is fascia?
is a thin casing of connective tissue that surrounds and holds every organ, blood vessel, bone, nerve fiber and muscle in place.
what is activated self isolated stretching?
the process of moving into a stretch and holding it for 1-2 seconds, repeat for 5-10 (uses reciprocal inhibition to help create an increase in joint range of motion)
what is dynamic stretching?
active extension of a muscle using force production and momentum to move through a full range of motion at higher speeds (also using reciprocal inhibition to increase joint range of motion)
Dynamic stretching improves soft tissue extensibility by using which of the following?
Reciprocal inhibition
what does a contraction of a muscle with a simultaneous relaxation of antagonist muscle indicative of?
reciprocal inhibition
