Warming-up and stretching for improved physical performance and prevention of sports-related injuries. Each subject was fully informed of the experimental purposes, procedures, and possible risks of the study. The subjects completed 3 different conditions: nonstretching (control, CON), SS, and PNF stretching (PNF). The MVC measurement method described by our previous study (28) was used, with modifications. The force for a 1-second period of steady state was averaged, and the highest value of the 3 trials was used for analysis. 2020 May 1;19(2):429-435. eCollection 2020 Jun. Some studies have shown that although ROM is increased, the effect of PNF stretching resembles that of SS (6,8,14,16,17,22). 29. Taylor DC, Dalton JD Jr, Seaber AV, Garrett WE Jr. Viscoelastic properties of muscle-tendon units. Freitas SR, Mendes B, Le Sant G, Andrade RJ, Nordez A, Milanovic Z. Scand J Med Sci Sports. eCollection 2020. For the SS group, we followed the protocol used by Behm et al. Reduced strength after passive stretch of the human plantarflexors. Not only will stretching reduce your risk of injury, proper stretching will help you feel less sore the next day. Sports Med 2: 267–278, 1985. Acute muscle stretching inhibits maximal strength performance. However, as discussed above, the additional increase of ROM by the CRAC method might be caused by the increased stretch tolerance in this study, although results suggest that increased ROM after stretching is attributable to decreased musculotendinous stiffness (23,35) and that ROM is negatively associated with musculotendinous stiffness (38). 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. It is important to understand the effects of various stretching types and define the most appropriate form in order to maximize the human movement and performance. 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). PNF = proprioceptive neuromuscular facilitation. Each condition consisted of a 5-minute rest accompanied by one of the following activities: (a) control, (b) SS, or (c) PNF stretching. Wolters Kluwer Health -. 10. The item(s) has been successfully added to ", This article has been saved into your User Account, in the Favorites area, under the new folder. (1992). Komi P. V., ed. [email protected]. Grieve DW, Gavanagh PR, Pheasant S. Prediction of gastrocnemius length from knee and ankle join posture In: Asmussen E, editor; , Jorgensen K, editor. Four theoretical mechanisms were identified: autogenic inhibition, reciprocal inhibition, stress relaxation, and the gate control theory. After the 8 week stretching Active vs. passive stretching--the benefits of both. Ogura Y, Miyahara Y, Naito H, Katamoto S, Aoki J. effects of other stretch modes (e.g., proprioceptive neuromuscular facilitation) have on DOMS still remains unclear in the literature (15). 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. Contract-relax. All the subjects were active in approximately 2–3 hours of recreational and competitive sports training or competition 3–4 times per week. It can be done alone, however it is typically performed with a partner who provides resistance and helps increase the 38. Volunteers (n = 122) were randomly divided into static, ballistic, and PNF stretching groups and a control group. A review. Proprioceptive Neuromuscular Facilitation Stretching PNFS is a stretching technique used to improve muscle elasticity and has been shown to have a positive effect on active and passive ROM. Please try after some time. Highlight selected keywords in the article text. The acute effects of static stretching on peak torque, mean power output, electromyography, and mechanomyography. 28. 3.4; AD Instruments Pty. This study was approved by the Juntendo University Human Ethics Committee in accordance with the Declaration of Helsinki. Etnyre BR, Abraham LD. Benefit Of PNF. Although stretching of various kinds such as static stretching (SS), ballistic stretching, dynamic stretching, and proprioceptive neuromuscular facilitation (PNF) stretching are known (19), only PNF stretching includes contraction of target muscles and the anatomical antagonist and stretching of target muscles. PNF stands for proprioceptive neuromuscular facilitation. 22. Reduce Stretching Risks With Post-Workout Routine Your post-workout routine should always include stretching – no matter how little time you feel you have. The risks associated with ballistic stretching far outweigh the gains, especially when better gains can be achieved by using other forms of stretching. The subjects then performed maximal isometric contraction of the hamstring muscles for 6 seconds. Contract/relax (a.k.a “PNF” stretching) Contract / Relax is a method of strengthening through a range of motion by using an isometric contraction held for a period of 10-20 seconds. 2. Significantly different from pre: **p < 0.01, ***p < 0.001. 29–38. Each subject repeated this sequence 3 times. E.g. Certain precautions ought to be observed when doing PNF stretches since they can place lots of stress on specific muscle groups, which can enhance the likelihood of getting soft tissue injuries. 39. In: Strength and Power in Sports. 23. Overall, stretching after exercise appears to be a key element in the muscle-restoration process. Magnusson SP. Take a closer look at passive and active stretching to learn more. -. While research on the acute effects of PNF on muscle performance is limited, interesting results have been obtained from a few recent studies. 6. Res Q Exerc Sport 72: 68–70, 2001. Figure 5 presents the iEMG values obtained during MVC. For example; For warming up, dynamic stretching is the most effective, while for cooling down, static and passive are best. Furthermore, we recorded neuromuscular activities of the biceps femoris muscle as a target muscle and the vastus lateralis muscle as the antagonist during stretching procedures and muscular contractions. Stretching is an excellent way to improve mobility and flexibility. Then hamstring muscles of the dominant leg were stretched by a skilled investigator to the point at which the subject first reported pain. Data is temporarily unavailable. Can J Appl Physiol 26: 261–272, 2001. Registered users can save articles, searches, and manage email alerts. Although, effects of static and PNF stretching (e.g., acute, long-term, etc.) The subjects crossed their arms in front of the chest. Static stretching is probably the safest form of stretch. Holcomb WR. Miyahara, Y, Naito, H, Ogura, Y, Katamoto, S, and Aoki, J. Fowles JR, Sale DG, MacDougall JD. 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). Sit on the floor with your legs extended out in front of you. For the PNF group, stretching was conducted according to the methods described by Holcomb (18), specifically the CRAC method. But, your post-workout routine shouldn’t end with stretching alone. Bradley PS, Olsen PD, Portas MD. Med Sci Sports Exerc 12: 322–329, 1980. In addition, in their study, improvements of ROM were very small (effect size: <0.1), showing no difference between CR and SS. J Athl Train 40: 94–103, 2005. Some reports have described that PNF stretching increased ROM more than SS did (11,32). Wilson GJ, Murphy AJ, Pryor JF. However, the improvements of ROM were slight and were not different between the types of stretching. in the long-term. The benefit of PNF stretching therefore may be highlighted in certain sports or clinical situations where improved ROM is more important than producing high isometric muscle force. Scientific, medical, and practical aspects of stretching. The aim of this study was to examine the acute effects of PNF stretching on knee extension and flexion peak torque (PT), as well as the conventional and functional hamstrings to quadriceps (H:Q) ratios. 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). Miyahara, Y, Naito, H, Ogura, Y, Katamoto, S, and Aoki, J. Consistent with the results of previous research on post-exercise static stretching, these results indicate that post-exercise PNF stretching also does not prevent DOMS. (4) reported that measures in both iEMG and ITT during MVC were decreased after SS. 3. Force elongation curve during a passive movement of the ankle angle. It was also reviewed that the CR method was enhanced tolerance to stretch and thereby CR increased ROM above that observed with SS although this technique reduced musculotendinous stiffness of stretched muscles and static (23).

These findings suggest that the additional increase of ROM by the CRAC method used in this study might be attributable to the increased stretch tolerance or increased pain threshold rather than the reduced musculotendinous stiffness of the hamstring muscles. PNF stretching PNF stretching can be used post-workout or as a separate flexibility session, but it is probably more effective immediately after exercise. Epub 2017 Oct 9. Cramer JT, Housh TJ, Weir JP, Johnson GO, Coburn JW, Beck TW. The positive aspects of PNF stretching are multiple, exceeding the normal stretching benefits. Stretching-induced impairment of muscular performance seems to be partly associated with lowered stiffness and lengthening of the target muscle (2,36). Briefly, the subjects were restrained by a nylon belt on a chair. There are many techniques for stretching in general, but depending on which muscle group is being stretched, some techniques may be ineffective or detrimental, even to the point of causing hypermobility, instability, or permanent damage to the tendons, ligaments, and muscle fiber. Influence of Aerobic Exercise After Static Stretching on Flexibility and Strength in Plantar Flexor Muscles. However, the greater ROM with PNF stretching may partly be attributed to increased pain threshold and thus hyper-ROM injuries such as strain might result. Proprioceptive neuromuscular facilitation (PNF) is an effective way of using reflexes to assist muscular relaxation. The subjects of the control group rested supine with both legs straight for 5 minutes. 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. Description. You may be trying to access this site from a secured browser on the server. 33. Epub 2018 May 22. Have your … Dynamic stretching can prepare your body for a workout by helping to loosen and warm up your muscles. Acute bouts of either PNF or static stretching caused similar deficits in knee extension power, measured by isokinetic dynamometry [16]. Search for Similar Articles Strength Cond J 22: 59–61, 2000. PNF stretching is a form of flexibility exercise that involves contracting and stretching the targeted set of muscles. , eds. A ground electrode was secured on the fibular head. Eur J Appl Physiol 86: 428–434, 2002. 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. 35. The test was conducted 3 times. P 23786/Austrian Science Fund FWF/Austria, Cabido CE, Bergamini JC, Andrade AG, Lima FV, Menzel HJ, Chagas MH. Power K, Behm D, Cahill F, Carroll M, Young W. An acute bout of static stretching: Effects on force and jumping performance. Although stretching has a positive effect on ROM improvement, it is often reported to have a detrimental effect on muscular performance (2–5,9,10,13,21,24,26–28,31,36). The pelvis was fixed with a band. PNF stretching may sound inconvenient because it typically involves a partner—but there is a way to perform self-administered PNF stretches. No recommendations can be made for or against PNF stretching prior to longer-duration cyclical endurance events, but the limited evidence regarding PNF stretching prior to submaximal muscular endurance activity is generally negative . J Appl Physiol (1985). A Leighton flexometer, strapped to the lateral thigh of the dominant leg, was adjusted to zero. We observed in this study that both PNF and SS showed a similar degree of decrease in iEMG in the biceps femoris muscle during MVC to that of the nonstretching condition. These results suggest that, although PNF stretching increases ROM more than SS, PNF stretching and SS is detrimental to isometric maximal strength.
