Proprioceptive Neuromuscular Facilitation Stretching
Stretching is usually included in the regular training program or part of warm-up activity before exercises. However, it is not that popular during the in-season training as it could compromise the muscle strength. Contract-relax proprioceptive neuromuscular facilitation CR-PNF stretching is generally known as an effective method to increase the joint range of motion, implying flexibility, but the chronic effect on muscle strength was not much studied.
The aim of this study was to investigate the chronic effects of 4-week CR-PNF stretching on muscle strength, i. Thirty-one male professional soccer players received the CR-PNF stretching of hamstring and quadriceps muscles for 4 weeks during the in-season training. Hip and knee range of motion and hamstring flexibility sit-and-reach test were measured before, at the end of each week and two weeks after the stretching session in order to see if the range of motion was maintained.
Knee flexion and extension isokinetic strengths were tested before and two weeks after the stretching session. The range of motion was progressively increased from the baseline measurement as can be observed since week 2 for hamstring hip and knee extension and week 3 for quadriceps hip and knee flexion , similarly for both dominant and non-dominant legs. It was concluded that during the in-season training, CR-PNF stretching was effectively able to increase the flexibility without the detrimental chronic effect on muscle strength.

PNF Stretching: A How-To Guide
Flexibility is key for athletes and nonathletes alike. It allows you to move freely and comfortably in your daily life, and can also help prevent injury during exercise. One of the best ways to increase your flexibility is by stretching. However, research suggests that not all stretching techniques are created equal. Proprioceptive neuromuscular facilitation PNF stretching relies on reflexes to produce deeper stretches that increase flexibility. Herman Kabat in the s as a means to treat neuromuscular conditions including polio and multiple sclerosis.
There is popularity of doing stretching as part of warm up before athletic activity. The static stretching and PNF stretching is performed by athletes but their effectiveness on sprinting performance is in state of debate. The objective is to determine the effect of static stretching and PNF stretching on sprinting performance in college sprinters and to compare the effects of PNF stretching over static stretching on sprinting performance in college sprinters. Both the groups received 5 minutes of warm-up exercises. However when comparing between group- A 6.

The Benefits of PNF (proprioceptive neuromuscular facilitation) Stretching
The effect of the contract-relax-agonist-contract CRAC stretch of hamstrings on range of motion, sprint and agility performance in moderately active males: A randomised control trial. This is followed by the antagonist muscle the quadriceps contracting. Forty healthy active males between 21 and 35 years old were assigned to either receive three repetitions of CRAC or rest. Therefore, CRAC appears to be a safe and effective method of increasing the length of the hamstrings pre-sport activity and should be utilised by sports physiotherapists if deemed necessary.
Proprioceptive neuromuscular facilitation PNF stretching techniques are commonly used in the athletic and clinical environments to enhance both active and passive range of motion ROM with a view to optimising motor performance and rehabilitation. PNF stretching is positioned in the literature as the most effective stretching technique when the aim is to increase ROM, particularly in respect to short-term changes in ROM. The inclusion of a shortening contraction of the opposing muscle appears to have the greatest impact on enhancing ROM.
PNF stretching was originally developed as a form of rehabilitation, and to that effect it is very effective. It is also excellent for targeting specific muscle groups, and as well as increasing flexibility, it also improves muscular strength. Side note : There are many different variations of the PNF stretching principle. Proprioceptive Neuromuscular Facilitation PNF is an advanced form of flexibility training, which involves both the stretching and contracting of the muscle group being targeted.
When most people think of fitness they think of cardiovascular and strength exercise—but those in the know go for the full trifecta of strength, cardio, and 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.
Proprioceptive neuromuscular facilitation PNF is common practice for increasing range of motion, though little research has been done to evaluate theories behind it. The purpose of this study was to review possible mechanisms, proposed theories, and physiological changes that occur due to proprioceptive neuromuscular facilitation techniques. Four theoretical mechanisms were identified: autogenic inhibition, reciprocal inhibition, stress relaxation, and the gate control theory.

PNF stretching is positioned in the literature as the most effective stretching technique when the aim is to increase ROM, particularly in respect to short-term changes in ROM. The mechanism(s) underpinning the change in stretch perception or tolerance are not known, although pain modulation has been suggested.
