The purpose of this study was to determine if static stretching has an effect on mean pre and postlanding muscle (vastus medialis VM, vastus lateralis VL, medial . Static stretching may result in various strength and power deficiencies. We applied a meta‐analytical approach to derive a robust estimate of the acute effects of pre‐exercise static stretching (SS) on strength, power, and explosive muscular performance. Nakamura, M., Ikezoe, T., Takeno, Y. 2004) and may be performed for many reasons but, probably, the most common is to increase flexibility.It is often assumed that these procedures change the physical properties of tendons (Witvrouw et al. The objective of this review was to identify studies that report the pre-exercise effects of isometric exercise versus static stretching on performance and injury rates of running athletes in comparison to their outcomes. static stretching was part of a warmup and cool down intervention; They stretched the entire lower limb for 3 sets of 10s; They had a 46.6% compliance rate. Subjects. Static stretching involves lengthening a specific muscle group for a period of time without movement. One common intervention that is used with most approaches is prolonged static stretching. Different stretching techniques have been used during warm-up routines. The benefits of providing static stretching exercise targeting the hips in patients with non-specific Low Back Pain (NSLBP) are not well established. We find a remarkable increase of friction with temperature, which we attribute to the formation . At follow-up assessment 6 weeks after . 1, 2 Different reasons for using stretching have been proposed, such as improved performance, 3 diminished delayed onset muscle soreness after unaccustomed exercise, 4 and increased range of motion. For the last several years, many people have warned others to avoid static stretching out of fear that the technique would ruin an individual's performance. [3] PNF incorporates static stretching in addition to isometric contraction and . Taking these results together with the results of the present study, we can conclude that only a static stretching program was able to decrease the PRT of the plantar flexors. Data sources : Randomised or quasi-randomised studies identified by searching Medline, Embase, CINAHL, SPORTDiscus, and PEDro, and by recursive checking of bibliographies. But, what I find most interesting is that many who might denigrate stretching in this study will then advocate dynamic stretching, a . The objective of the study was to verify the effects of static stretching on function, pain and range of motion on patients with non-specific Low Back Pain (NSLBP). For a general fitness program, the American College of Sports Medicine1recommends static stretching for most individuals that is preceded by an active warm-up, at least 2 to 3 days per week. Nevertheless, the static stretching prior to the climbing exhibited an increase of myofibers Type IIa diameter and appeared to benefit the oxidative response and muscle strength. 2004) but there is little objective evidence to support this view. Seven male subjects performed static stretching in which the ankle was passively flexed to 35° of dorsiflexion and remained stationary for 10 min. The intensity of static stretching is determined according to the range of motion (ROM) 14,17,18 or point of discomfort . Though much more research is needed to clarify the effects of foam rolling, recent investigations have indicated that it is an effective method for improving flexibility, subjective markers of recovery (i.e. Static stretching in Makaruk et al. The purpose of this study was to determine the effects of cyclic static stretch (CSS) on fatigue recovery of triceps surae (TS) in female basketball players. Mizuno, T., Matsumoto, M. & Umemura, Y .

Objective: To investigate the acute effects of different stretching intensities on the range of motion (ROM), passive torque, and muscle architecture. This study aimed to evaluate motor unit recruitment during submaximal voluntary ramp contraction in the medial head of the gastrocnemius muscle (MG) by high-density spatial electromyography (SEMG) before and after static stretching (SS) in healthy young adults. View Article PubMed/NCBI Google Scholar 2. Novel ankle self-stretching using a strap (SSS) may be a . The results of this study suggest that, although both static stretch and DROM will increase hamstring flexibility, a 30-second static stretch was more effective than the newer technique, DROM, for enhancing flexibility. Another doubt about stretching is "the lack of a relationship. Method : Systematic review. CONCLUSION: The use of static stretching at the end of the training sessions prevents the negative effect of the load on hamstring flexibility and it can influence improvement in flexibility. The purpose of this study was to compare the acute effect of a ballistic and a static stretching protocol on lower-limb maximal strength. Dynamic stretching boosts athletic performance; static stretching reduces it. Static stretching is defined as passively stretching a given muscle-tendon unit by slowly placing it in a maximal position of stretch and sustaining it there for an extended period of time. A static stretch is performed by placing muscles at their greatest possible length and holding that position for a period of time [ 15 ]. DOMS), and . 16- 18 Investigators 16, 18- 21 have shown that stretching of the plantar-flexor muscles for periods ranging between 30 minutes and 6 weeks, imposed with a tilt table or cast, reduced passive ankle joint resistance, increased ankle joint range of . A computerized search of articles published between 1966 and December 2010 was performed using PubMed, SCOPUS, and Web of Science databases.

Static stretching is where a muscle is elongated to the Point Of Discomfort (POD), and held for a period of time, often between 30 seconds and 2 minutes. Objective : To determine the effects of stretching before and after exercising on muscle soreness after exercise, risk of injury, and athletic performance. Static stretching at various durations has been shown to be a widespread practice among athletes during training sessions for different muscle groups or before competitions [].Static stretching can lead to an acute increase in the angle of motion [].However, recent research has shown that stretching applied to various muscle groups may have adverse effects on maximal muscle strength . , Allison et al. Additionally, the comparison between the groups . CONCLUSION: Both static stretching and ballistic stretching increase range of motion, most likely as a result of enhanced stretch tolerance rather than changes in muscle elasticity. It is estimated that by 2030 the prevalence of symptomatic OA could reach 30 % of the population above 60 years. In static stretching, one stretches the muscles past their comfort zones and holds the body in the stretched position for a few seconds unlike ballistic exercises where there is a repetitive movement. Asian Journal of Sports Medicine, 4(1), 1-9. concluded that 10 minutes of static stretching decreased the viscosity of the tendinous structures and increased their elasticity. Effect of frequency of static stretching on flexibility, hamstring tightness and electromyographic activity We compared the effect of the number of weekly repetitions of a static stretching program on the flexibility, hamstring tightness and electromyographic activity of the hamstring . As one might expect, the physiology of static stretching differs from the cascade of events occurring during dynamic stretching. Introduction. Static stretching resulted in an increase in sarcomeres, while ballistic stretching had a greater influence on the stiffness of the Achilles tendon. Share this article via email with one or more people using the form . Seven electronic databases were searched: Cochrane, PEDro, CINAHL, PubMed, MEDLINE, SportDiscus, and GoogleScholar. The current study aims to investigate the acute effects of light aerobic activity, static stretching (SS), strengthening and explosive exercises on lower-body muscular performance and range of motion (ROM). Dynamic stretching has been shown to either have no effect or may augment subsequent performance, especially if the duration of the dynamic stretching is prolonged. Stretching also has other acute effects on the neuromuscular system. Seven electronic databases were searched: Cochrane, PEDro, CINAHL, PubMed, MED … Prehab Exercises Static Stretching is an illustrated guide to the ABC Approach for Static Stretching that was created by Michael Rosengart. Download Prime PubMed App to iPhone, iPad, or Android the static stretching technique is a widely used method that extends the muscle length by autogenic inhibition exciting the golgi tendon organ. Static stretching of the hamstring muscle for injury prevention in football codes: A systematic review. . 2. Jul 2008;16(3):213-231 [PubMed] 6. Increased ROM with stretching is a well-described phenomenon that is more likely the result of a rise in stretch tolerance (reduced mechanoreceptor and nociceptor activity during stretching) of the muscles than a decrease in muscle/tendon stiffness or a change in muscle architecture (Freitas et al. Dose-response effect of SS on performance and ROM was also studied. To assess the effects in belly muscle triggered by static stretching prior to climbing, it was necessary to observe changes in the myonuclei and the interstitium. Static stretching is where a muscle is elongated to the Point Of Discomfort (POD), and held for a period of time, often between 30 seconds and 2 minutes. While most of those pre-workout regimens were based in static stretching, we have seen more dynamic stretching being incorporated in warm-up programs. 1997;77(10):1090-6. pmid:9327823. 21, 36, 37 Static stretching . Static stretching is regarded as the most common form of stretching for the general public or average fitness participant, since it is considered safe and effective for improving overall flexibility. Dynamic stretching is a newer, preferred way to stretch before a workout but there's still a place for static stretching. Muscle injury measures showed that the Dynamic stretching group scored the highest on muscle injury incidence (6%), while only 1 player (3%) was injured in the static group. Osteoarthritis (OA) is a highly prevalent and disabling disease. We introduce a model for zwitterionic monolayers and investigate its tribological response to changes in applied load, sliding velocity, and temperature by means of molecular-dynamics simulations. Stretching is a technique used to increase muscle joint range of motion (ROM) [1,2,3].Passive and active static, and dynamic stretching techniques were developed to increase levels of ROM and improve specific sport techniques [4,5,6].Although, passive and active static stretching (SS) techniques seem to provide the greatest changes in ROM, it is also well documented that they can acutely . , and Hayes et al. Dynamic stretching is a newer, preferred way to stretch before a workout but there's still a place for static stretching. Each stretch should be held 15-30 seconds and repeated 2 to 4 times. Static stretching is the most commonly prescribed type of stretching involving placement of the body and limbs in an extreme ROM position and holding this position for a period by gravity, partner assistance, or agonist muscle tension. Static stretching (SS) is commonly used as a part of a warm-up routine in order to increase range of motion (ROM) and potentially prevent injuries [].Previous review studies reported that SS increases ROM effectively [2-5].However, it is pointed out that the passive property of the muscle-tendon unit and tolerance for stretching influences ROM [5-7]. , and Hayes et al. of static stretching as part of the warm-up for the prevention of exercise-related injuries. Introduction. Static stretching, therefore, appears to improve flexibility and do so by increasing passive fascicle length and decreasing passive fascicle angle. Dynamic stretching is where the muscle is moved through its Range Of Motion (ROM), without being held in the stretched position. PubMed journal article: Effect of global posture reeducation and of static stretching on pain, range of motion, and quality of life in women with chronic neck pain: a randomized clinical trial. specifically, static stretching (sts) involves a controlled continuous movement to the end range-of-motion (rom) of a single joint or multiple joints by either actively contracting the agonist muscles (i.e., active static) or by using external forces such as gravity, partner, stretching aids (i.e., passive static with stretch bands) ( behm et … Dynamic stretching is where the muscle is moved through its Range Of Motion (ROM), without being held in the stretched position. pubmed.ncbi.nlm.nih.gov › 19784479. Thirty females with NSLBP were randomly assigned to two control (n = 15) and . Static stretching (SS) is commonly used as a part of a warm-up routine to increase flexibility and prevent sports-related injuries.1 Increasing range of motion (ROM) is essential to prevent the occurrence of sports-related injuries.2-4 Previous studies reported that SS increased ROM5 and is effective in the prevention of muscle-tendon injuries, such as muscle strain.6 There . Nineteen young male soccer players (age: 13.9 ± 0.46 years . , Allison et al. 13, 38 This maximal stretching position is determined by the moderate discomfort and/or pain that the patient experiences. With the hip remaining at 90° flexion, the researcher passively raised the lower leg, extending the subject's knee to full extension. 5, 8 recommendations for the … A variety of ankle self-stretching exercises have been recommended to improve ankle-dorsiflexion range of motion (DFROM) in individuals with limited ankle dorsiflexion. Static stretching may actually provide benefits in some cases such as slower velocity eccentric contractions, and contractions of a more prolonged duration or stretch-shortening cycle. Context: Although stretching exercises are commonly used in clinical and athletic practice, there is a lack of evidence regarding the methodological variables that guide the prescription of stretching programs, such as intensity. Main outcome measures : Muscle soreness . Before and after the stretching, the elongation of the tendon and aponeurosis of medial . A strap can be applied to stabilize the talus and facilitate anterior glide of the distal tibia at the talocrural joint during ankle self-stretching exercises. & Ichihashi, N.

Kubo et al. PubMed journal article: Selective effect of static stretching, concentric contractions, and a balance task on ankle force sense. This method is arguably the safest form of stretching, especially for beginners, as it minimizes the risk of tearing or straining the muscle by overstretching. For instance, significant reductions in maximal voluntary strength, muscle power or evoked contractile properties have been recorded immediately after a single bout of static stretching, raising interest in other stretching modalities. PubMed PubMed Central Google Scholar 19. Techniques of stretching include 1. The purpose of this study was to determine the optimal time and frequency of static stretching to increase flexibility of the hamstring muscles, as measured by knee extension range of motion (ROM). SS for gastrocnemius was performed in 15 healthy participants for 2 min.

The purpose of this study was to investigate the influences of static stretching on the viscoelastic properties of human tendon structures in vivo. People also ask. 1 More recent studies indicate that stretching does not, as previously . In contrast, dynamic stretching involves moving the limb from its neutral position to end range, where the muscles are at their greatest length and then moving the limb back to its original position. In a chronic study, the same group combined resistance exercises with static stretching; exercise were performed for 45 seconds with 15-second intervals, two sessions a day, 7 days a week for 8 weeks. Four weeks of stretching maintain range of motion and stretch tolerance in the days after eccentric exercise. The objective of this review was to identify studies that report the pre-exercise effects of isometric exercise versus static stretching on performance and injury rates of running athletes in comparison to their outcomes. Stretching is commonly used in relation to physical activity and rehabilitation of patients with musculoskeletal disorders. Static stretching is recommended to be included as part of a fundamental warm-up program to prevent muscle-tendon injuries 1.In order to prevent muscle-tendon injuries such as muscle strain . Searches of PubMed, SCOPUS, and Web of Science were per-formed for studies published in English up to and including December 2010.We used the following search phase (static stretch OR static stretching OR acute stretch OR acute stretching OR passive stretch OR warm-up) AND (strength OR force OR torque OR jump OR sprint OR throw OR performance). Reviews of PubMed, Science Direct, Medline, AMED, and EMBASE websites were conducted to identify the term 'contracture reduction' in manuscripts published from January 2002 to January 2012. To add to this, static stretching appears to decrease neural excitability by as much as 16-88%, observed by changes in spinal reflex and H-reflex responses [44]. 7) In the studies, static stretching was performed at different points, either during warm-up [1,2] or during [44] or after exercise [1,2,12,44]. Static stretching is likely what comes to mind when you think of stretching, in general - calf stretches, toe touches, standing hamstring and quad stretches, and many yoga poses. 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. Normalized peak torque by bodyweight of the plantar flexor . No incidence of muscle injury was recorded in the DTFM group over the follow-up. While stretching and ROM increases go hand in hand, something that hasn't been investigated is the effect of static (SS) and dynamic stretching (DS) on athletic performance during a series of .
