1. Eleven healthy male students took part in this study. The Effects of Hamstring Stretching on Range of Motion: A Systematic Literature Review Laura C. Decoster, ATC1 Joshua Cleland, DPT, OCS2 Carolann Altieri, PT3 Pamela Russell, PhD4 Study Design: Systematic literature review. “When you’re static stretching,” she notes, “the muscles aren’t warmed up. Static stretching means a stretch is held in a challenging but comfortable position for a period of time, usually somewhere between 10 to 30 seconds. Increases your flexibility. Static and Dynamic Stretching - The Importance of Stretching Decades ago, static stretching was claimed to be an effective way to help reduce injury risks in athletes. However, many experts consider static stretching much less beneficial than dynamic stretching for improving range of motion for functional movement, including sports and activities for daily living. According to Dr. Rex, static stretching fell out of favor as a warm-up routine because research found that static stretching induced some detrimental effects, like reducing maximal strength, power and performance after a single bout of a static stretch. These authors concluded that in static stretching the muscle itself was affected, not the tendon, possibly due to an increase in the number of sarcomeres. The risks associated with ballistic stretching far outweigh the gains, especially when better gains can be achieved by using other forms of stretching. Due to the slow and controlled speed at which stretches are performed, the risk for injury is minimal provided proper static stretching techniques are used. Much of the research would suggest that combin-ing static and dynamic stretching may attenuate the dele-terious effects of the static stretching within a warm-up (Behm and Chaouachi, 2011). Strive for symmetry. Feet at shoulder width and place your … By Emily R Pappas, M.S. Static stretching uses a slow, constant speed and generally involves holding the stretched position for an extended period of time (usually 30 sec). So as we grow older, with the decreased integrity of the … Each subject performed static stretching and dynamic stretching on the 5 muscle groups in the lower limbs an … The timing of stretching also impacts its effectiveness, with the greatest benefits of static stretching coming after a workout, rather than before. Epub 2017 Jan 25. Clinicians who evaluated muscle function in athletes observed one outstanding factor — stretching a muscle could make it longer (the reason it increases flexibility), and this resulted in a reduction in function from a loss of power. Effects of elastic taping, non-elastic taping and static stretching on … Static stretching is a type of stretching exercises in which elongation of muscle with application of low force and long duration (usually 30 sec). Static stretching is more beneficial when done after exercising. The effects of stretching begin to reduce fifteen minutes after stretching but flexibility still remains above the starting point and remains at the level for at least 24 hours post-stretching. While static stretching involves holding a stretch for an extended period, dynamic stretching is a continuous movement that puts joints and muscles through a full range of motion. It is during these stretches that it is important to increase the circulation to the tired muscles and release any tension that may have built up. Static stretching is important for reducing the risk of injury, increasing flexibility, and improving recovery time from workouts. The effects of static stretching (StS) on subsequent strength and power activities has been one of the most debated topics in sport science literature over the past decades. The Potential Dangers of Stretching Too Much Stretching a muscle that isn't warmed up, even a little bit, poses a big risk of injury. More recent evidence suggests that when performed as a single-mode treatment or when integrated within a full warm-up routine including aerobic activity, dynamic-stretching, and sport-specific activities, short-duration StS (≤60 s per muscle group) trivially impairs subsequent strength and power activities (∆1-2%). This means you can sit or stand still while you hold a stretch for about 20-30 seconds. Traditionally, static stretching has always been done prior to a workout, yet recent research has shown that static stretching prior to training has a number of negative effects, such as; Reducing muscle strength by nearly 5.5% (when held for more than 90 seconds) Cutting muscle power by 2%; Reducing explosive muscular performance by nearly 3% Regular stretching can help increase your flexibility, which is crucial for … If we choose not to, we could experience significant decrements in our ability to perform intense movements because decreased joint stability and neurological functioning 52 . Static stretching seems to be subject to conflicting opinion. Static stretching has a relaxation,elongation effect on muscle,improving range of motion (ROM) , decreasing musculotendinous stiffness and also reduce the risk of acute muscle strain injuries.It is a slow controlled movement with emphasis on postural awareness and body alignment. You will feel "looser" after a static stretch, but the short term effects fade pretty fast. Rather than striving for the … A static active stretch should be held for 10-30 seconds for 1-2 stretches per muscle group. If we do, we can shed many of the potentially negative effects of static stretching by just giving it a little time. Everyone's genetics for flexibility are a bit different. But as times change, so does our understanding of what static stretching does and DOES NOT do for our athletes. Objective: Investigate the literature regarding the most effective positions, techniques, and durations of stretching to improve hamstring muscle flexibility. The increased range of motion of the joint has been shown to last for around 3-15 minutes post-stretch. In other words, stretching caused abnormal inhibition — … If a muscle on one side of your body is tighter than a muscle on the other side, it creates an asymmetry that can increase the risk of injury, Laskowski said. Dynamic stretching was proposed to have more effect on the tendon, increasing both the storage and release … This also applies for contract-relax or proprioceptive neuromuscular facilitation (PNF) stretching. The practice of increasing flexibility through static stretching in the fitness industry is standard. For example, a group of The majority of the current research suggests that static stretching PRIOR to activity can induce temporary weakness in the muscle, decrease the ability of the muscle receptor to engage the “stretch reflex” and can increase injury risk. The purposes of this study were to clarify the effects of static stretching for 30 seconds and dynamic stretching on leg extension power. Hip Circles. These days there are many studies that caution us away from stretching before workouts. Example of static stretching taken from Facilitated Stretching, 4th Edition. Res Sports Med. Michael Boyle states in his book New Functional Training for Sports that static stretching has gone from being the best way to warm up to being something no-one should ever do again. It is suitable for all patient types. This is a serious health danger. Static stretching is the most common form of stretching found in general fitness and is considered safe and effective for improving overall flexibility. The purpose of this study was to analyze the effects of static stretching on functional capacity of older women. What is ballistic stretching. As we have seen, with age the collagen/elastin ratio changes in favor of collagen. Ballistic stretching or “bouncing” stretching, is dynamic stretching that involves rapid, alternating movements or ‘bouncing’ at end-range of motion; however, because of increased risk for injury, ballistic stretching is no longer recommended 1).. 2017 Apr-Jun;25(2):181-190. doi: 10.1080/15438627.2017.1282360. Take a standing position with your chest up. Some research has found that static stretching can have detrimental effects on subsequent performance. Dynamic stretc… Static stretching actually decreases muscle power for a period of time – the period is debatable, but at least 5 minutes and up to 3 hours – after stretching is performed 1,2. It may impair balance and reaction time (3) and reduce power output and without any of the benefits of injury prevention (4,5,6). As with other forms of stretching, static active stretching is not recommended before a sporting event. Both static stretching and dynamic stretching before exercise have been found to be beneficial for different types of athletic activities. static stretching with aerobic endurance exercises did not adversely affect repeated sprint abilities (Wong et al., 2011). A considerable body of literature indicates that static stretching performed prior to strength- and power-dominant activities results in performance deficits, including such tasks as countermovement jump height, 1RM in the bench press, and peak torque output (2–7,11,13,20,22,28,34,42,44,45,50,52,59,62).
