What Is PNF Stretching?
PNF stretching is an advanced form of flexibility training that involves contraction and stretching of muscles. The technique was originally born in the clinical rehabilitative
environment, but has worked its way into mainstream gyms because it is so effective.
PNF stretching requires the help of a partner or an inanimate object. To perform a PNF stretch, you will alternate between a static stretch-and-hold and an isometric contraction of the muscle being stretched.
For example, to perform a PNF stretch of the hamstring with a partner:
Lie on your back with one leg extended toward the ceiling.
Stretch: Have your partner move your leg into a static stretch by pressing it gently toward your face. Hold the static stretch for about 10 seconds.
Contract: Contract the hamstring muscles and push your leg against your partner’s hand while your partner resists the movement. Hold the contraction for about 5-10 seconds.
Stretch: Relax the muscles and allow your partner to carefully move the leg past its normal range of movement. Hold this passive, static stretch for about 20 to 30 seconds.
Rest for 30 seconds and then repeat the procedure two to three more times.
Improving Range of Motion with PNF Stretching
PNF stretching has been proven to improve active and passive range of motion. It can be used to supplement daily, static stretching and has been shown to help athletes improve performance and make speedy gains in range of moti
on. Not only does it increase flexibility, but it can also improve muscular strength.
Multiple studies have shown that PNF stretching is superior to traditional static stretching in terms of improving range of motion. It is also excellent for targeting specific muscle groups. What’s more, PNF stretching is believed to prevent knots and realign muscle fibers and connective tissue after microscopic damage that typically follows a high-intensity workout.
Incorporating PNF Stretching into Your Routine
PNF stretching may sound inconvenient because it typically involves a partner—but there is a way to perform self-administered PNF stretches. For example, to perform a self-PNF hamstring stretch, place your foot on a chair or bench and perform a static stretch followed by an isometric contraction and another static stretch. Research has shown that this is an equally effective way to reap the benefits of PNF stretching.
One caveat: be sure to perform PNF stretching after a workout, as any type of stretching prior to a workout can reduce power output.
