Which of the following activities best describes proprioceptive neuromuscular facilitation?
a.
the stretch involves using an external object to increase muscle strength.
b.
the stretch involves using a partner to apply force against your contraction.
c.
the stretch involves bouncing to extend beyond the normal range of motion.
d.
the stretch involves performing slow, deliberate motions to reduce muscle tightness.

The stretch involves using a partner to apply force against your contraction as your neuromuscles are facilitated the best when in conjunction with outside help. Proprioceoive neuromuscular facilitation will be very hard if not impossible without someone there to help and apply force against your contraction.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.two years ago, when picking flowers in the mountains back of yosemite valley; i found a book. it was blotted and storm-beaten, all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however, many of the inner pages were well preserved. and although all were more or less stained and torn; whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today, its granite pages have been torn and blurred by the same storms that wasted the castaway book.
