USA.gov. Acute passive stretching alters the mechanical properties of human plantar flexors and the optimal angle for maximal voluntary contraction. 14. The positive aspects of PNF stretching are multiple, exceeding the normal stretching benefits. For the SS group, we followed the protocol used by Behm et al. Behm DG, Kay AD, Trajano GS, Blazevich AJ. It can be done alone, however it is typically performed with a partner who provides resistance and helps increase the Arch Phys Med Rehab 1996: 77(7): 688–692. Static stretching. 2017). Acute muscle stretching inhibits maximal strength performance. 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. 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). Performing PNF before exercise can provide Injury risks and reduces long term benefits as All data were expressed as mean ± SD. Wilson GJ, Wood GA, Elliott BC. Scand J Med Sci Sports. Get new journal Tables of Contents sent right to your email inbox, January 2013 - Volume 27 - Issue 1 - p 195-201, Effects of Proprioceptive Neuromuscular Facilitation Stretching and Static Stretching on Maximal Voluntary Contraction, Articles in Google Scholar by Yutetsu Miyahara, Other articles in this journal by Yutetsu Miyahara, The Influence of Strength, Flexibility, and Simultaneous Training on Flexibility and Strength Gains, Acute Effects of Different Stretching Durations on Passive Torque, Mobility, and Isometric Muscle Force, Acute Effects of the Different Intensity of Static Stretching on Flexibility and Isometric Muscle Force, Acute Effect of a Ballistic and a Static Stretching Exercise Bout on Flexibility and Maximal Strength, Effect of Warm-Ups Involving Static or Dynamic Stretching on Agility, Sprinting, and Jumping Performance in Trained Individuals, National Strength and Conditioning Association. Acute bouts of either PNF or static stretching caused similar deficits in knee extension power, measured by isokinetic dynamometry [16]. The MVC of knee flexion was then measured. The Acute Effects of Antagonist Stretching on Agonist Movement Economy. Static: Static stretching is a passive stretch given to the antagonist muscle by placing it in a maximal position if stretch and holding it there for a period of time. 8. The Effects of Cold Application and Modified PNF Stretching Techniques on Hip Joint Flexibility in College Males. to maintaining your privacy and will not share your personal information without Results of the MVC tests are presented in Figure 4. (36) found that motor unit activation was not decreased after SS. This study was approved by the Juntendo University Human Ethics Committee in accordance with the Declaration of Helsinki. Power K, Behm D, Cahill F, Carroll M, Young W. An acute bout of static stretching: Effects on force and jumping performance. However, the correlation analysis suggests it is possible the pre-stretch muscle contractions of the post-exercise PNF protocol may have placed a load on an already damaged muscle causing more DOMS for some … 2017 Aug;117(8):1649-1656. doi: 10.1007/s00421-017-3654-5. Both SS and PNF significantly increased the ROM (p < 0.01 and p < 0.001, effect size = 0.26 and 0.83, respectively). 1. -. Research Quarterly for Exercise and Sport: Vol. Not only will stretching reduce your risk of injury, proper stretching will help you feel less sore the next day. None reported any current or recent injury. For more information, please refer to our Privacy Policy. 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. The biomechanical effects of stretching. 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. Phys Ther 67: 24–30, 1987. The hamstring muscles stretched by the PNF might produce higher levels of neuromuscular activity than SS does. Am J Sports Med 18: 300–309, 1990. 2020 May 1;19(2):429-435. eCollection 2020 Jun. However, the decreases were very small compared with those found in this study. Static stretching is probably the safest form of stretch. Miyahara, Y, Naito, H, Ogura, Y, Katamoto, S, and Aoki, J. PNF stands for proprioceptive neuromuscular facilitation.

Neuromuscular basis of stretching exercise. 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). 2018 May 1;27(3):289-294. doi: 10.1123/jsr.2016-0098. NIH Conclusions Stretching can be dangerous when performed incorrectly. , eds. 2020 Sep 1;13(4):1295-1304. eCollection 2020.
