2018 Mar;28(3):794-806. doi: 10.1111/sms.12957. 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). The test was conducted 3 times. 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. A 2007 study investigated the long-term effects of PNF and static stretching on range of motion and jump performance. 2017). 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. Ogura Y, Miyahara Y, Naito H, Katamoto S, Aoki J. Proprioceptive neuromuscular facilitation (PNF) may produce slightly larger gains in flexibility of some joints compared with other techniques, but it is less practical because of the need for a partner 13) . The respective increases of ROM in the CON, SS, and PNF groups were 0 ± 1°, 4 ± 4°, and 12 ± 6°. Reduce Stretching Risks With Post-Workout Routine Your post-workout routine should always include stretching – no matter how little time you feel you have. Acute effects of stretching on the neuromechanical properties of the triceps surae muscle complex. Avela J, Kyrolainen H, Komi PV. Lempke L, Wilkinson R, Murray C, Stanek J. J Sport Rehabil. Epub 2017 Jun 17. This position was maintained for 45 seconds; it was followed by a 15-second relaxation period during which subjects placed both legs straight. Ltd.). Duration of static stretching influences muscle force production in. Proprioceptive neuromuscular facilitation (PNF) is common practice for increasing range of motion, though little research has been done to evaluate theories behind it. Although many reasons for the conflict are proposed, such as differences of PNF methods used, target muscles, types of contraction, and characteristics of subjects, the conflict is not well explained because only performance data are available in some study. For example; For warming up, dynamic stretching is the most effective, while for cooling down, static and passive are best. None reported any current or recent injury. 32. Consequently, more research is necessary to draw conclusions about the acute effects of stretching on neuromuscular activities during muscle force generation. Active vs. passive stretching--the benefits of both. Only in the PNF stretching group, the pennation angle in the stretched position (-4.2%) and plantar flexor MVC (-4.6%) decreased significantly. Each subject was fully informed of the experimental purposes, procedures, and possible risks of the study. Range of motion was recorded by a goniometer. PNF stretching is a form of flexibility exercise that involves contracting and stretching the targeted set of muscles.

Passive properties of human skeletal muscle during stretch maneuvers. Significantly different from pre: **p < 0.01, ***p < 0.001. Both SS and PNF significantly increased the ROM (p < 0.01 and p < 0.001, effect size = 0.26 and 0.83, respectively). Results of this study demonstrated that the increase in ROM is significantly greater after PNF stretching than after SS for hamstring muscles. You can take your time and push yourself to the limit easily without worrying about accidentally pushing yourself too far. Behm DG, Kay AD, Trajano GS, Blazevich AJ. 25. Effects of proprioceptive neuromuscular facilitation stretching and static stretching on maximal voluntary contraction. J Sports Sci Med. Stretches can also be modified so you can do them alone or with a partner. Church JB, Wiggins MS, Moode FM, Crist R. Effect of. Take a closer look at passive and active stretching to learn more. Effect of PNF stretching training on the properties of human muscle and tendon structures. It has been suggested that stretching-induced impairment of muscular performance is associated with lowered stiffness of the target muscle and neuromuscular activity during muscle force generation. Static stretches may be better suited … 29. 3.4; AD Instruments Pty. Another is called “Contract or Hold Relax” (CR or HR), which includes mainly autogenic inhibition (20). Lower: ΔROM (post-pre) in CON, SS, and PNF. Musculotendinous stiffness: Its relationship to eccentric, isometric, and concentric performance. With the PNF exercises, the muscle groups are put through a routine of stretching and contracting. 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). Grieve DW, Gavanagh PR, Pheasant S. Prediction of gastrocnemius length from knee and ankle join posture In: Asmussen E, editor; , Jorgensen K, editor. Not only will stretching reduce your risk of injury, proper stretching will help you feel less sore the next day. 800-638-3030 (within USA), 301-223-2300 (international)
The Recovery of Muscle Spindle Sensitivity Following Stretching Is Promoted by Isometric but Not by Dynamic Muscle Contractions. 31. Ltd.). Six mobilization exercises for active range of hip flexion. 35. During both the stretching and the contraction phase of the PNF stretch it’s not necessary to apply maximum force or intensity. 33. The MVC measurement method described by our previous study (28) was used, with modifications. In addition, in their study, improvements of ROM were very small (effect size: <0.1), showing no difference between CR and SS. Moore MA, Hutton RS. J Sports Sci 23: 449–454, 2005. 17. Performing PNF before exercise can provide Injury risks and reduces long term benefits as No significant difference in MVC was found between the SS and PNF groups (effect size = 0.02). 10. You may be trying to access this site from a secured browser on the server. Electromyographic investigation of muscle stretching techniques. An injured muscle … Wilson GJ, Wood GA, Elliott BC. Such muscle activation might be associated with the actual force generation during stretching. The time course of the effects of constant‐angle and constant‐torque stretching on the muscle–tendon unit. (4) and Power et al. Behm DG, Button DC, Butt JC. Search for Similar Articles
Force elongation curve during a passive movement of the ankle angle. Improved stretching with proprioceptive neuromuscular facilitation. 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). Before and after the 4 × 30 s stretching intervention, we determined the maximum dorsiflexion range of motion (RoM) with the corresponding fascicle length and pennation angle of the gastrocnemius medialis. (31). Thorough skin preparation for all electrodes included removal of dead epithelial cells around the designated areas with subsequent cleansing using an isopropyl alcohol swab. Registered users can save articles, searches, and manage email alerts. All the subjects were active in approximately 2–3 hours of recreational and competitive sports training or competition 3–4 times per week. The results were in line with previous studies that showed decreases in MVC for knee extension (4) and 1RM for knee flexion and extension (21) after SS and which showed decreases in the isokinetic concentric strength (24) and dynamic performance such as vertical jumping (5,7) after PNF stretching. Values are expressed as mean ± SD. Marek SM, Cramer JT, Fincher AL, Massey LL, Dangelmaier SM, Purkayastha S, Fitz KA, Culbertson JY.
