Behm DG, Kay AD, Trajano GS, Blazevich AJ. Mechanisms underlying performance impairments following prolonged static stretching without a comprehensive warm-up. to maintaining your privacy and will not share your personal information without PNF stands for Proprioceptive Neuromuscular Facilitation.According to the IPNF Association, PNF stretching was developed by Dr. Herman Kabat in the 1940s.It was developed to treat neuromuscular conditions including polio and multiple sclerosis. Then hamstring muscles of the dominant leg were stretched by a skilled investigator to the point at which the subject first reported pain. For example, SS decreased 1-repetition maximum (1RM) (21), maximal voluntary contraction (MVC) (4,13,28), jump performance (5,9), and sprint performance (27). March 10, 2011, Harri Daniel, Comments Off on Benefit Of PNF. Your message has been successfully sent to your colleague. Sports Biomech 3: 159–183, 2004. 31. Soleus muscle electromyographic activity and ankle dorsiflexion range of motion during four stretching procedures. The gray…, NLM This work was supported by grants from the Graduate School of Health and Sports Science, and Institute of Health and Sports Science and Medicine, Juntendo University. Weir DE, Tingley J, Elder GC. Fowles et al. 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. It involves actively using your own muscles to achieve range of motion; as the antagonist (opposite) muscle contracts, the agonist (target) muscle groups lengthen and relax. Stretching to the point of pain had no acute advantages over stretching to the discomfort point. J Strength Cond Res 27(1): 195–201, 2013—This study was undertaken to investigate and compare the effects of proprioceptive neuromuscular facilitation (PNF) stretching and static stretching on maximal voluntary contraction (MVC). Magnusson SP. Miyahara, Y, Naito, H, Ogura, Y, Katamoto, S, and Aoki, J. -. The initial recommended procedure for PNF stretching is to perform the desired PNF technique 3-5 times for a given muscle group (resting 20 seconds between each repetition). The subjects were then required to raise the dominant leg to its limit slowly, without swinging or bouncing, while the investigator held the opposite leg firmly in contact with the padded table. PNF Stretching By looking through the internet one is lead to believe that pnf stretching is all there is to PNF. It is believed that the greater motor pool inhibition reduces muscle contractibility, makes muscles more compliant, and provides greater potential for muscle lengthening than common SS does (12). In this study, we confirmed decreases of MVC after both static and PNF stretching from the control level. Res Q Exerc Sport 69: 411–415, 1998. For example, it was reported that the quadriceps contraction during final stretch phase in the CRAC method induced contraction of the hamstring muscles to keep maximal extension of the knee and the hamstring muscles under considerable tension, although CRAC increased ROM more than CR and SS (29,30). Conclusions The pelvis was fixed with a band. PNF stands for proprioceptive neuromuscular facilitation. The integrated EMG (iEMG) was calculated from the EMG over a 1-second period while at a steady state of MVC using a computer software program (Chart ver. Behm DG, Button DC, Butt JC. A 2007 study investigated the long-term effects of PNF and static stretching on range of motion and jump performance. 29–38. The average room temperature and the relative humidity of the laboratory were, respectively, 21.5 ± 0.4° C and 48.5 ± 4.9% (mean ± SD). Avela J, Kyrolainen H, Komi PV. 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. The test–retest correlation (Pearson's r) of MVC was 0.92. Surface electromyography was recorded from the biceps femoris and vastus lateralis muscles during MVC tests and stretching. Neuromuscular basis of stretching exercise. With the PNF exercises, the muscle groups are put through a routine of stretching and contracting. (24), which showed that CR of the vastus lateralis muscle resulted in similar deficits in isokinetic muscular strength and power output to those of SS. Keywords: However, we did not directly measure musculotendinous stiffness. The ICCRs over 3 days were 0.802 (95% CI; 0.588–0.928) and 0.531 (95% CI; 0.203–0.802).

Benefits Of PNF Stretching #1 PNF technique produces the largest gains in flexibility! Ogura Y, Miyahara Y, Naito H, Katamoto S, Aoki J. Biomechanics, VI‐A. Am J Sports Med 18: 300–309, 1990. Int J Exerc Sci. Young adult participants (N=57) were randomly assigned to a PNF stretching group (n=19), a static stretching group (n=20), and to The acute effects of static stretching on peak torque, mean power output, electromyography, and mechanomyography. In this test, the intraclass correlation coefficient (ICC) R of the 3 serial measurements was 0.998 (95% confidence interval [CI]; 0.996–0.999) and the ICCR of the prestretching in 3 days was 0.938 (95% CI; 0.855–0.979). Regular stretching can help increase your flexibility, which is crucial … The biomechanical effects of stretching. Ltd.). Res Q Exerc Sport 72: 273–279, 2001. Shellock FG, Prentice WE. 2018 Mar;28(3):794-806. doi: 10.1111/sms.12957. 2014 Jul 1;117(1):29-35. doi: 10.1152/japplphysiol.00195.2014. Epub 2017 Oct 9. Ltd.). In many cases, stretching is also an important part of a …  |  Finally, a concentric contraction of quadriceps muscles and passive stretching of the hamstring muscles were performed simultaneously for 30 seconds, followed by a 14-second relaxation period. HHS Briefly, the pelvis of each subject was fixed to the padded table with a band. In fact, some studies have demonstrated decreased capability in vertical jumping after CR (5) and CRAC (7) and in isokinetic concentric muscular strength after CR (24). eCollection 2020. Influence of High Intensity 20-Second Static Stretching on the Flexibility and Strength of Hamstrings. and PNF stretching on DJ might produce new data regarding their rehabilitation processes. Some reports have described that PNF stretching increased ROM more than SS did (11,32). Influence of Aerobic Exercise After Static Stretching on Flexibility and Strength in Plantar Flexor Muscles. However, no data related to this point are available. Although increases in ROM were significantly greater after PNF than after SS (p < 0.01), the decreases in MVC were similar between the 2 treatments. None reported any current or recent injury. Stretching falls into 4 different categories; static, dynamic, ballistic and proprioceptive neuromuscular facilitation (PNF). Effect of PNF stretching training on the properties of human muscle and tendon structures. Electroencephalogr Clin Neurophysiol 63: 174–179, 1986. See this image and copyright information in PMC. The main finding of this study is that although PNF stretching increased ROM more than SS, the extent of the decrease of MVC is similar between PNF and SS (Figure 6). Observation of muscle-tendon junction (MTJ) displacement with ultrasound allowed us to determine the length changes in the tendon and muscle, respectively, and hence to calculate stiffness. The iEMG in the vastus lateralis muscle during the stretch phase was significantly greater for the PNF group than for the SS group (p < 0.05, effect size = 1.46).  |  A review. The Acute Effects of Antagonist Stretching on Agonist Movement Economy. Similarly, the iEMG in the biceps femoris muscle, although slight, was significantly greater for the PNF group than for the SS group (p < 0.05, effect size = 1.30) (Figure 3). PNF is an advanced form of stretching that allows you to target a specific muscle group and stretch it as well as strengthen it. Each condition consisted of a 5-minute rest accompanied by one of the following activities: (a) control, (b) SS, or (c) PNF stretching. (31). 63, No. © 2017 The Authors Scandinavian Journal of Medicine & Science In Sports Published by John Wiley & Sons Ltd. Chalmers G. Re-examination of the possible role of golgi tendon organ and muscle spindle reflexes in proprioceptive neuromuscular facilitation muscle stretching. J Athl Train 40: 94–103, 2005. Please enable it to take advantage of the complete set of features! The iEMG was measured for activities in (b) and (d). Stretching is widely used by many athletes before exercise training and competition (33,34) because it increases range of motion (ROM) and it is commonly believed that increased ROM contributes not only to injury prevention but also to improved athletic performance (1). In addition, in their study, improvements of ROM were very small (effect size: <0.1), showing no difference between CR and SS. Scientific, medical, and practical aspects of stretching. For the PNF group, stretching was conducted according to the methods described by Holcomb (18), specifically the CRAC method. Background: The effects of proprioceptive neuromuscular facilitation (PNF) stretching on muscle imbalance are not fully understood. (limit 100 words) Stretching Benefits Risks Static (passive and active) A slow, easy pace conducive to relaxation and steadiness. This type of exercise is typically used in the rehabilitation process because of its proven effectiveness, but it also helps target specific muscle groups for improving strength and flexibility. Twenty-three healthy male volunteers were randomly divided into 3 groups to follow a static stretching program, PNF stretching program, or a control group with no stretching. Stretches can also be modified so you can do them alone or with a partner. To expect greater changes in the ROM, we selected hamstring muscles (hip joint) as target muscles and used the CRAC method, which is expected to cause both autogenic and reciprocal inhibitions. Values are expressed as mean ± SD. Thorough skin preparation for all electrodes included removal of dead epithelial cells around the designated areas with subsequent cleansing using an isopropyl alcohol swab. H-reflex changes during static stretching and two variations of proprioceptive neuromuscular facilitation techniques. Definition: PNF stretching is an advanced method of flexibility training that includes stretching… During both the stretching and the contraction phase of the PNF stretch it’s not necessary to apply maximum force or intensity. The purpose of this study was to investigate the influence of a single static, ballistic, or proprioceptive neuromuscular facilitation (PNF) stretching exercise on the various muscle-tendon parameters of the lower leg and to detect possible differences in the effects between the methods. This result resembles those reported for a previous study by Marek et al. I t is generally well accepted dogma in the health and fitness industry (as in athletic conditioning) that stretching is an important part of a regular training program. Then SS and PNF were repeated, respectively, 5 times. 1. The Journal of Strength & Conditioning Research27(1):195-201, January 2013. In the above video I talk about the basic principles behind PNF and show you a simple PNF stretching routine for 4 basic muscle groups: quads, hamstrings, calves and chest. 25. J Sports Sci 23: 449–454, 2005.  |  We investigated the acute effects of PNF stretching on ROM and MVC of hamstring muscles compared with those of SS. -. To begin, the subject's hamstring muscles were passively stretched for 10 seconds by the same skilled investigator. Guissard N, Duchateau J, Hainaut K. Muscle stretching and motoneuron excitability. Proprioceptive Neuromuscular Facilitation (PNF): Its Mechanisms and Effects on Range of Motion and Muscular Function. 7. Each subject was fully informed of the experimental purposes, procedures, and possible risks of the study. Epub 2014 May 8. One is called “Contract or Hold Relax Agonist Contract” (CRAC or HRAC), which includes both autogenic and reciprocal inhibitions. Increases your flexibility. The increase in RoM and the decrease in PRT and muscle-tendon stiffness could be explained by more compliant muscle tissue following a single static, ballistic, or PNF stretching exercise. Res Q Exerc Sport 72: 68–70, 2001. Wilson GJ, Murphy AJ, Pryor JF. Registered users can save articles, searches, and manage email alerts. It is generally accepted that stretching is important. We used a counterbalanced, within-subjects experimental design to assess the acute effects of 2 conditions of stretching on MVC, integrated electromyography (iEMG), and ROM (Figure 1). Search for Similar Articles Etnyre BR, Abraham LD. Although previous reports have described that both PNF and SS reduced the excitability of the alpha-motoneuron pool controlling the stretched muscle by autogenic inhibition in originating Golgi tendon organs and reciprocal inhibition (8,12,15), we observed a higher level (about twice) of iEMG in the stretched biceps femoris muscle during PNF stretching than during SS (Figure 3).
