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: A How-To Guide

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. PNF stretching is one of the most effective forms of stretching for improving flexibility and increasing range of motion. This video explores the benefits, precautions, and routines of PNF 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.


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. Skip to main content Skip to main navigation menu Skip to site footer.

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. The greatest changes in ROM generally occur after the first repetition and in order to achieve more lasting changes in ROM, PNF stretching needs to be performed once or twice per week. Instead, and in the absence of a biomechanical explanation, the contemporary view proposes that PNF stretching influences the point at which stretch is perceived or tolerated. The mechanism s underpinning the change in stretch perception or tolerance are not known, although pain modulation has been suggested.

What is PNF Stretching?

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. To perform a PNF stretch, you will alternate between a static stretch-and-hold and an isometric contraction of the muscle being stretched.

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.

The Practical Guide to Improving Flexibility

Хейл внезапно почувствовал беспокойство - скорее всего из-за необычного поведения Сьюзан. Он быстро пересек комнату и преградил ей дорогу, скрестив на груди руки. - Скажи мне, что происходит, - потребовал .

Подумала она удивленно и с облегчением и попыталась выскользнуть из-под. - Милый, - глухо прошептала.  - Позволь, я переберусь наверх.  - Но немец даже не шевельнулся.

 Понятия не имею. Я уже говорила, что мы ушли до их прибытия. - Вы хотите сказать - после того как стащили кольцо. - Мы его не украли, - искренне удивилась Росио.

Офицер покачал головой, словно не веря своим глазам. - Я должен был вам рассказать… но думал, что тот тип просто псих.
