It's only about like 3-5% and only for like 15-30 minutes after stretching. Or one or two sets as discussed in one of Lyle's previous articles.
Basically, stretching out the muscle spindles makes them "more unresponsive" to changes in muscle length thus decreasing stretch-shorten cycle activity during strength/power movements.
The same may be true of golgi tendon organs, but I'm not sure about that one.
