21
Q

Method of action that static stretching uses primarily

A

autogenic inhibition

22
Q

what is autogenic inhibition?

A

When neural impulses of the GTO are greater than the impulses of the muscle contractions creating an inhibition effect

23
Q

How long do you hold a static stretch? Why?

A

30 seconds, it takes that long for the GTO to override the muscle spindle

Q

Dynamic stretching is included in what level of flexibility?

A

Functional flexibility

26
Q

Active-isolated stretching uses what method of action?

A

reciprocal inhibition

27
Q

active-isolated stretching acute variables

A

1-2 seconds for 5-10 reps

28
Q

dynamic stretching acute variables

A

1-2 sets of 10-15 reps for 3-10 exercises

29
Q

Heart Rate Reserve/Karvonen method

A

[(HRmax-HRrest) x intensity]+HRrest

30
Q

what is reciprocal inhibition?

A

the simultaneous contraction of one muscle(agonist) and the relaxation of another(antagonist)
