PNF stretching
PNF stretching (“proprioceptive neuromuscular facilitation”) is a method to increase one's flexibility, in which a muscle is alternatingly stretched passively and contracted. The technique claims to use the nerve receptors in the muscles to reset the muscle length.
- First, the relaxed muscle is stretched by an external force, such as an exercise partner, or by ones own body weight against the floor, a wall, or similar resistance.
- At the point, where no further stretching seems possible, the stretch is hold for about 30 seconds. However, during this period, the muscle should be contracted as much as possible. (In the drawing on the right, this is done by trying to press the feet into the floor.)
- Finally, when the muscle gets relaxed again, it should be immediatly stretched further, which is then easily possible again.
This technique of alternating stretching and contracting can be repeated several times, in order to get a bit further each time.
Advocates suggest that PNF stretching is typically more effective and more comfortable than conventional stretching, based on the theory that it works with the body's own neural mechanisms.
