Abstract:
Background/aims High-intensity static stretching is assumed to increase the range of motion and/or decrease muscle stiffness; however, the effects of high-intensity static stretching on the quadriceps muscle have been debated. Hot pack application before high-intensity static stretching was assumed to decrease stretching pain, which is the main problem in high-intensity static stretching, and decrease quadriceps muscle stiffness. This study aimed to examine hot pack application before high-intensity static stretching on stretching pain, knee flexion range of motion, and quadriceps muscle stiffness. Methods In total, 21 healthy sedentary male participants randomly performed two interventions: high-intensity static stretching and hot pack application before stretching. Static stretching was performed at three 60-second stretching interventions with a 30-second interval. Then, a 20-minute hot pack was applied before high-intensity static stretching. The knee flexion range of motion and shear elastic modulus of the quadriceps muscle were measured by ultrasonic shear-wave elastography before and after the static stretching intervention. Results Stretching pain after hot pack application before stretching was lower than high-intensity static stretching alone. Significant increases were also found in knee flexion range of motion after both stretching interventions, but no significant difference was noted in the increase in the knee flexion range of motion with or without hot pack application. No significant change was found in quadriceps muscle stiffness in either intervention. Conclusions The results suggest that hot pack application before high-intensity static stretching could decrease stretching pain, but no significant difference in knee flexion range of motion increase was found.

Abstract:
The aim of this study is to investigate the acute effects of different stretching methods on acceleration, vertical jump (CMJ), flexibility and upper extremity performance of young wrestlers. 8 young female wrestlers (15.37 ± 1.06 years; 162.46 ± 4.12 cm and 57.47 ± 6.41 kg) participated in the study voluntarily. Stretching methods were divided into five groups: control (no stretching), static, dynamic, static + dynamic and dynamic + static. The findings showed faster speed performance after control (p = .012; η2 = 0.57), dynamic stretching (p = .050; η2 = 1.11) and static + dynamic combined stretching (p = .043; η2 = 0.96) compared to static stretching; and there is a statistically significant positive difference according to the test averages after dynamic stretching (p = .050; η2 = 0.91) compared to dynamic + static combined stretching (p<0.05). Vertical jump performance, according to the control warming up, a statistically significant difference has been found according to the test averages after dynamic stretching (p = 041; η2 = 1.17) and static + dynamic combined stretching (p = .043; η2 = 1.07). No difference was found in flexibility and medicine ball throwing performances according to different stretching protocols (p>0.05). . It was determined that the acute effect of static stretching had a negative effect on acceleration performances and dynamic stretching caused an increase in jump performance. This study suggests that dynamic and static + dynamic stretching can be used in young wrestlers to provide better performance in acceleration and jumping skills during warm-up sessions.

Abstract:
AbstractThis randomized cross-over study examined the effects of typical static and dynamic stretching warm-up protocols on repeated-sprint performance. Thirteen young female handball players performed a 5 min aerobic warm-up followed by one of three stretching protocols for the lower limbs: (1) static stretching, (2) dynamic-ballistic stretching, and (3) no stretching before performing five all-out sprints on a cycle ergometer. Each protocol was performed on a different occasion, separated by 2-3 days. Range of movement (ROM) was also measured before and after the warm-up protocols with a sit-and-reach test. Fixed and random effects of each stretching protocol on repeated sprint performance were estimated with mixed linear modeling and data were evaluated via standardization and magnitude-based inferences. In comparison to no stretching, there were small increases in ROM after dynamic stretching (12.7%, ±0.7%; mean, ±90% confidence limits) and static stretching (19.2%, ±0.9%). There were small increases in the average power across all sprints with dynamic stretching relative to static stretching (3.3%, ±2.4%) and no stretching (3.0%, ±2.4%) and trivial to small increases in the average power in the 1st and 5th trials with dynamic stretching compared to static stretching (3.9%, ±2.6%; 2.6%, ±2.6%, respectively) and no stretching (2.0%, ±2.7%; 4.1%, ±2.8%, respectively). There were also trivial and small decreases in power across all sprints with static relative to dynamic stretching (-1.3%, ±2.8%) and no stretching (-3.5%, ±2.9%). Dynamic stretching improved repeated-sprint performance to a greater extent than static stretching and no stretching.

Abstract:
This study analyzed the effect of static stretching on performance during drop jumps. Furthermore, we investigated if a reduction in drop height would compensate the stretching-caused alterations. Ten physically active male subjects performed drop jumps at four different drop heights without static stretching for the optimal drop height determination. After, they performed drop jumps on two drop heights with static stretching previously. The jump height, contact time and reactive strength index were significantly affected by static stretching. However, only the contact time was significantly improved by the reduction in drop height with previous static stretching. Our results suggest that the decrement in performance after static stretching could be partially compensated by a reduction in drop height, which decreases the contact time near a non-stretching jump condition. This can be explained by the lower landing velocity and, possibly, the smaller reduction in the activation of the plantar flexors muscles. In conclusion, the reduction in drop height seems to be interesting after a static stretching session, aiming to expose the athletes to lower impact forces to maintain jump performance.

Abstract:
Objective To compare the effectiveness of static stretching techniques for correcting the tightness of the triceps surae.Methods In this observational, cross-sectional study, participants (30 healthy volunteers) completed 10 repetitions of each stretching exercise, holding each stretch for 10 seconds, with a 1-minute rest period between repetitionsand a 1-hour rest period between the two stretching techniques, namely, wall and inclined board stretchings. The length of the triceps surae and range of ankle dorsiflexion were measured on lateral view radiographs. The muscle activity during the stretch was measured using quantified surface electromyography of the lateral gastrocnemius. The subjective stretching sensation was evaluated using the visual analog scale.Results Both stretching techniques showed statistical differences in all the parameters. Stretching on an inclined board yielded a greater increase in the triceps surae length than did wall stretching (mean difference, 0.72; p=0.02). The range of ankle dorsiflexion was higher with inclined board stretching than with wall stretching (mean difference, 2.57; p=0.03). The mean muscle activity was significantly lower withinclined board stretching than with wall stretching (mean difference, 53.72; p<0.01). The visual analog scale score was higher with inclined board stretching than with wall stretching (mean difference, 2.07; p<0.01).Conclusion In this study, inclined board stretching was more effective than wall stretching for correcting tightness of the triceps surae. Therefore, inclined board stretching should be encouraged for the triceps surae.

Abstract:
Electromyography Assessments of the Vastus Medialis Muscle during Soccer Instep Kicking between Dynamic and Static StretchingThe purpose of this study was to examine the effects of static and dynamic stretching within a pre-exercise warm-up on vastus medialis muscle activity during instep kicking and ball velocity in soccer players. The kicking motions of dominant legs were captured from using six synchronized high-speed infra-red cameras at 200 Hz and Electromyography at 100 Hz. There was significant difference in vastus medialis activity after dynamic stretching relative to no stretching condition (0.12 ± 0.06 mV) versus static stretching relative to no stretching condition (-0.21 ± 0.10 mV) with p < 0.001). In addition, there was also a significant difference in ball velocity after dynamic stretching relative to no stretching condition (4.53 ± 2.10 m/s) versus static stretching relative to no stretching condition (-1.48 ± 2.43 m/s) with p < 0.003. We concluded that dynamic stretching during the warm-up, as compared to static stretching, is probably more effective as preparation for optimal muscle activity and finally have high ball velocity which is required in soccer.

Abstract:
The purpose of this study was to determine the combined effects of static stretching and electrical muscle stimulation on maximal dorsiflexion angle and passive properties. Sixteen healthy subjects participated in three randomly ordered experimental trials: combined static stretching and electrical muscle stimulation, static stretching alone, and control. In combined trial, subjects performed 5 min of calf stretching while receiving electrical muscle stimulation of the gastrocnemius medialis. In static stretching trial, subjects performed calf stretching only. Maximal dorsiflexion angle, passive torque, and muscle displacement were measured before and after intervention. Tendon displacement was also calculated. The difference from pre- to post-intervention in maximal dorsiflexion angle in combined trial was greater compared with that in the control (p = 0.026), but the static stretching trial exhibited no significant difference (both p > 0.05). Passive torque at submaximal dorsiflexion angles was significantly decreased only after combined trial (all p < 0.05). Muscle displacement at maximal dorsiflexion angle was significantly increased in all conditions (all p < 0.05). Tendon displacement at maximal dorsiflexion angle was higher after combined trial compared with static stretching trial (p = 0.030). These results revealed additional effects of adding electrical muscle stimulation to static stretching on maximal dorsiflexion angle, passive torque, and tendon displacement.

Abstract:
Although athletes routinely perform warm-up and stretching exercises, it has been suggested that prolonged stretching immediately before an activity might negatively affect the force production. Sixteen male pubescent soccer players participated in the study to examine whether a routine duration of acute static stretching is responsible for losses in isokinetic peak torque production. All participants performed two static stretching protocols in nonconsecutive training sessions. The first stretching protocol was performed three times for 15 s (volume 45) and the second 20 times for 15 s (volume 300). Range of motion (ROM) was determined during knee flexion with the use of a goniometer. The peak torque of the dominant leg extensors was measured on a Cybex NORM dynamometer at various angular velocities. The statistical analysis showed that peak torque did not change following the static stretching for 45 s in all angular velocities, while it decreased (p < .001) in all angular velocities following the static stretching for 5 min. The findings suggest that strength decreases after static stretching exercises may be the result of the performed stretching duration.

Abstract:
Clinical Scenario:Increasing hamstring flexibility through clinical stretching interventions may be an effective means to prevent hamstring injuries. However the most effective method to increase hamstring flexibility has yet to be determined.Clinical Question:For a healthy individual, are proprioceptive neuromuscular facilitation (PNF) stretching programs more effective in immediately improving hamstring flexibility when compared with static stretching programs?Summary of Key Findings:A thorough literature search returned 195 possible studies; 5 studies met the inclusion criteria and were included. Current evidence supports the use of PNF stretching or static stretching programs for increasing hamstring flexibility. However, neither program demonstrated superior effectiveness when examining immediate increases in hamstring flexibility.Clinical Bottom Line:There were consistent findings from multiple low-quality studies that indicate there is no difference in the immediate improvements in hamstring flexibility when comparing PNF stretching programs to static stretching programs in physically active adults.Strength of Recommendation:Grade B evidence exists that PNF and static stretching programs equally increase hamstring flexibility immediately following the stretching program.

Abstract:
Hamstring flexibility is reduced due to postural adaptations and this can cause limitations in joint range of motion and muscular imbalance and can affect physical performance of a person. The Neurodynamic sliding technique, PNF stretching and Static stretching are three different techniques that have shown improvement on Hamstring flexibility. The aim of the present study is to compare the short term and long term effects of Neurodynamic sliding, PNF stretching and Static stretching on Hamstring flexibility in young subjects with hamstring tightness. A comparative study was conducted on 63 subjects, who were divided into 3 groups, A, B and C. Group A received Neurodynamic sliding, Group B received Static stretching and Group C received PNF Stretching. The intervention was given 3 times per week for 4 weeks, Pre and post test of Hamstring flexibility were assessed using passive knee extension test, Straight Leg Raise and Active Knee Extension test. Follow up values were taken after one month. The results from all three outcome measures suggest that Group B has greater short term effects when compared to other groups (p<0.05), whereas, group A have greater long term effect than group B and group C (p<0.05). The study concluded that both interventions significantly improved Hamstring flexibility, but Static stretching has greater immediate effect in improving Hamstring flexibility than other two types of stretching, whereas, Neurodynamic sliding have more long term effect. PNF stretching has immediate effects but was less significant than static stretching and their effects where not carried to long term.

Abstract:
According to the International Diabetes Federation's Diabetes Atlas 2006, the number of diabetics will top 70 million by next mid-decade. Type I and type II are the two variations diabetes that exist. 90-95% of diabetics have type 2 DM. Recent studies have shown that exercise and physical activity reduce blood sugar levels. Yoga, aerobics, swimming, stretching, and resistance training improve insulin sensitivity. As type II diabetes can cause neuropathies, hypertension, and amputations, static stretching may help those who can't do regular exercise. People who have been bedridden for a long time or who are too old to do other types of exercise may benefit from static stretching. Earlier research was done to compare the immediate effects of static stretching vs. resistance exercises on blood sugar levels after a meal in people with type II diabetes mellitus. Long-term consequences of static stretching on type II diabetes unpredictable blood sugar levels are unknown. This study examined the effect of static stretching on type II diabetics' random blood sugar levels. Key words: Diabetes, Stretching, exercises, aerobic exercise, blood glucose level..

Abstract:
A strain gradient was created by punching a hole in the center of a stretched elastic polydimethylsiloxane membrane to determine the effect of different strains on cultured human keratocytes (HK). In this study, two stretching methods were used: continuous stretching and cyclic stretching. Continuous stretching is relatively static, while acyclic stretching is relatively dynamic. These methods, respectively, represented the effects of high intraocular pressure and rubbing of the eyes on corneal cells. Image processing codes were developed to observe the effects of stress concentration, shear stress, continuous stretching, and cyclic stretching on HKs. The results demonstrate that stretching and shear stress are not conducive to the proliferation of corneal cells and instead cause cell death. A 10% strain had greater inhibitory effects than a 3% strain on cell proliferation. Cell survival rates for continuous stretching (static) were higher than those for cyclic stretching (dynamic). The stretching experiment revealed that cyclic stretching has a greater inhibitory effect on the growth and proliferation of corneal cells than continuous stretching. Accordingly, it shows that cyclic loading is more harmful than high intraocular pressure (static loading) to corneal cells.

Abstract:
Background: For decades, static stretching has been the standard benchmark for training programs, because it has been shown to increase flexibility compared with other methods of stretching. Objective: The current study investigated and compared the effects of active dynamic stretching and passive static stretching on hamstring tightness. Methods: For this experiment, 64 female students were enrolled and randomly assigned to active dynamic or passive static stretching groups (n=32 each). The first and second experimental groups were trained with repetitive dynamic stretching and static stretching exercises, respectively. Exercises were performed 10 times per limb, 3 times per day, 5 days per week for 4 weeks. Hamstring muscle length measurements were repeated in weeks 2 and 4. Statistical analysis of the results was performed by t-test and repeated measures ANOVA using SPSS 15. Results: Both experimental groups showed significant improvements in the active knee extension range of motion during the intervention (P<0.001). However, active stretching showed better results and had a greater effect on range of motion in comparison with static stretching. Conclusion: Active dynamic training can be considered a suitable method for increasing the flexibility of the hamstring muscle and, consequently, reducing the complications and problems associated with hamstring tightness.

Abstract:
Context: Hamstring injuries are common, and lack of hamstring flexibility may predispose to injury. Static stretching not only increases range of motion (ROM) but also results in reduced muscle strength after stretching. The effects of stretching on the hamstring muscles and the duration of these effects remain unclear. Objective: To determine the effects of static stretching on the hamstrings and the duration of these effects. Design: Randomized crossover study. Setting: University laboratory. Participants: A total of 24 healthy volunteers. Interventions: The torque–angle relationship (ROM, passive torque [PT] at the onset of pain, and passive stiffness) and isometric muscle force using an isokinetic dynamometer were measured. After a 60-minute rest, the ROM of the dynamometer was set at the maximum tolerable intensity; this position was maintained for 300 seconds, while static PT was measured continuously. The torque–angle relationship and isometric muscle force after rest periods of 10, 20, and 30 minutes were remeasured. Main Outcome Measures: Change in static PT during stretching and changes in ROM, PT at the onset of pain, passive stiffness, and isometric muscle force before stretching were compared with 10, 20, and 30 minutes after stretching. Results: Static PT decreased significantly during stretching. Passive stiffness decreased significantly 10 and 20 minutes after stretching, but there was no significant prestretching versus poststretching difference after 30 minutes. PT at the onset of pain and ROM increased significantly after stretching at all rest intervals, while isometric muscle force decreased significantly after all rest intervals. Conclusions: The effect of static stretching on passive stiffness of the hamstrings was not maintained as long as the changes in ROM, stretch tolerance, and isometric muscle force. Therefore, frequent stretching is necessary to improve the viscoelasticity of the muscle–tendon unit. Muscle force decreased for 30 minutes after stretching; this should be considered prior to activities requiring maximal muscle strength.

AbstractIn this study, we examined the effects of static and dynamic stretching on range of motion (ROM), passive torque (PT) at pain onset, passive stiffness, and isometric muscle force. We conducted a randomized crossover trial in which 16 healthy young men performed a total of 300 s of active static or dynamic stretching of the right knee flexors on two separate days in random order. To assess the effects of stretching, we measured the ROM, PT at pain onset, passive stiffness during passive knee extension, and maximum voluntary isometric knee flexion force using an isokinetic dynamometer immediately before and after stretching. Both static and dynamic stretching significantly increased the ROM and PT at pain onset (p<0.01) and significantly decreased the passive stiffness and isometric knee flexion force immediately after stretching (p<0.01). However, the magnitude of change did not differ between the two stretching methods for any measurements. Our results suggest that 300 s of either static or dynamic stretching can increase flexibility and decrease isometric muscle force; however, the effects of stretching do not appear to differ between the two stretching methods.

Abstract:
Although warm-up and stretching exercises are routinely performed by gymnasts, it is suggested that stretching immediately prior to an activity might affect negatively the athletic performance. The focus of this investigation was on the acute effect of a protocol, including warm-up and static and dynamic stretching exercises, on speed during vaulting in gymnastics. Eleven boys were asked to perform three different protocols consisting of warm-up, warm-up and static stretching and warm-up and dynamic stretching, on three nonconsecutive days. Each protocol was followed by a “handspring” vault. One-way analysis of variance for repeated-measures showed a significant difference in gymnasts’ speed, following the different protocols. Tukey’s post hoc analysis revealed that gymnasts mean speed during the run of vault was significantly decreased after the application of the static stretching protocol. The findings of the present study indicate the inhibitory role of an acute static stretching in running speed in young gymnasts.

Abstract:
A warm-up helps the individuals to prepare themselves for strenuous workouts. The warm-up is generally executed before participation in any physical activity or sports. The objective of the study was to investigate the effects of sequencing lower-body static and dynamic stretching combinations on agility, speed, and leg power of school-level female Netball players. Three different stretching protocols were performed: (a) Static Stretching combined with Dynamic Stretching (SS+DS), (b) Dynamic Stretching combined with Static Stretching (DS+SS), and (c) Dynamic Stretching combined with Dynamic Stretching (DS+DS). A control warm-up condition without stretching was implemented with a prior aerobic warm-up followed by dynamic activities. Dependent variables included a 30-m Sprint, Agility run, and jump tests to measure speed, agility, and leg power performance. The level of significance was set at 5% for statistical analysis. The method used for statistical analysis was two-way ANOVA. There was no significant impact of stretching protocols on agility (p=0.257), speed (p=0.106), and leg power (p=0.902) of school-level female netball athletes. The results of the analysis allow the authors to retain the hypothesis that a sequence of static and dynamic stretching combinations does not significantly affect the agility, speed, and leg power of school-level female netball athletes.

AbstractThe purpose of this study was to investigate the acute effect of different stretching methods, during a warm-up, on the acceleration and speed of soccer players. The acceleration performance of 20 collegiate soccer players (body height: 177.25 ± 5.31 cm; body mass: 65.10 ± 5.62 kg; age: 16.85 ± 0.87 years; BMI: 20.70 ± 5.54; experience: 8.46 ± 1.49 years) was evaluated after different warm-up procedures, using 10 and 20 m tests. Subjects performed five types of a warm-up: static, dynamic, combined static + dynamic, combined dynamic + static, and no-stretching. Subjects were divided into five groups. Each group performed five different warm-up protocols in five non-consecutive days. The warm-up protocol used for each group was randomly assigned. The protocols consisted of 4 min jogging, a 1 min stretching program (except for the no-stretching protocol), and 2 min rest periods, followed by the 10 and 20 m sprint test, on the same day. The current findings showed significant differences in the 10 and 20 m tests after dynamic stretching compared with static, combined, and no-stretching protocols. There were also significant differences between the combined stretching compared with static and no-stretching protocols. We concluded that soccer players performed better with respect to acceleration and speed, after dynamic and combined stretching, as they were able to produce more force for a faster execution.

Abstract:
Background: flexibility that is one of basic aspects of any sport program , can be developed and acquired through various stretching exercises. This study examined the effect of six-weeks of static stretching on hamstring flexibility in high school females. Methods: Thirty healthy high school females aged 15 to 17 years were randomly assigned to one of two groups. The training group underwent static stretch training of the hamstring with a six-weeks protocol training sessions were 3 days per week, including 4 30-seconds stretches per day for each of subjects. The other group acted as control group. Before and after six-weeks of stretching, flexibility of the hamstring muscles was determined by Sit & Reach Test. Results: A significant increase in flexibility of hamstring was found in training group (mean 31cm to 39/87cm), and no significant difference was revealed in hamstring flexibility after the six-weeks static stretching for the control group. Conclusion: This study indicated that the static stretching significantly increased the hamstring flexibility and suggests that subjects use static stretching for increasing their hamstring flexibility.DOI: http://dx.doi.org/10.3126/ijls.v8i5.10914

Abstract:
Background: Patellofemoral pain (PFP) syndrome is closely associated with muscle tightness. However, studies regarding the effects of stretching exercises on PFP patients with inflexible hamstrings are scarce. The aim of the study was to compare the effects between static and dynamic hamstring stretching in patients with PFP who have inflexible hamstrings. Hypothesis: Compared with static hamstring stretching, dynamic hamstring stretching will improve the parameters of hamstring flexibility, knee muscle strength, muscle activation time, and clinical outcomes in this patient population. Study Design: Prospective randomized controlled trial. Level of Evidence: Level 2. Methods: A total of 46 patients (25, static stretching; 21, dynamic stretching) participated. Hamstring flexibility was assessed according to the popliteal angle during active knee extension. Muscle strength and muscle activation time were measured using an isokinetic device. Clinical outcomes were evaluated using the visual analog scale (VAS) for pain and the anterior knee pain scale (AKPS). Results: There were no differences in hamstring flexibility and knee muscle strength of the affected knees between the groups ( P > 0.05). Significantly improved muscle activation time and clinical outcomes of the affected knees were observed in the dynamic stretching group compared with the static stretching group (all Ps < 0.01 for hamstring, quadriceps, VAS, and AKPS). Conclusion: In patients with PFP who have inflexible hamstrings, dynamic hamstring stretching with strengthening exercises was superior for improving muscle activation time and clinical outcomes compared with static hamstring stretching with strengthening exercises. Clinical Relevance: Clinicians and therapists could implement dynamic hamstring stretching to improve function and reduce pain in patients with PFP who have inflexible hamstrings.

Abstract:
AbstactThe present study aimed to examine the effects of using static or dynamic stretching added to the common warm-up routine for short sprint distances and to repeated sprint performance. In 3 different sessions, 16 college-age men (n=10) and women (n=6) performed one of 3 warm-ups followed by a 2×60 m dash sprint time trial (5 min of rest) in a counterbalanced design. The control warm-up consisted of 10 min of light-intensity running, and the 2 experimental warm-ups included a static or dynamic stretching routine (5 exercises) in the control warm-up. Performance (time) and physiological variables (tympanic temperature, heart rate) were monitored. In the first 60 m time trial, there were no differences between the 3 warm-ups tested (F=0.21, p=0.73; ηp 2=0.01), as opposed to that observed in the second (F=7.04, p<0.01; ηp 2=0.32). The participants were 1.7% faster after the static stretching warm-up compared with the control warm-up. The sum of the time performed in the 2 sprints emphasizes these results, with better performances after the static stretching warm-up than the control (1%) or dynamic stretching warm-up (0.7%). These results suggest that including a set of static or dynamic stretching exercises may enhance sprinting performance. The better performance in the second trial after the warm-up including static stretching suggests that this type of stretching may positively influence repeated sprint performance (<10 s sprint).

Abstract:
Objectives: To compare the different stretching techniques, proprioceptive neuromuscular facilitation (PNF) stretching and static stretching, in patients with elbow stiffness after a treated elbow fracture. Design: Randomized-controlled, single-blind study. Setting: Department of physiotherapy and rehabilitation. Subjects: Forty patients with posttraumatic elbow stiffness (24 women; mean age, 41.34 ± 7.57 years). Intervention: PNF stretching group ( n = 20), hold-relax PNF stretching combined with a structured exercise programme (two days per week for six weeks); static stretching group ( n = 20), static stretching combined with a structured exercise programme (two days per week for six weeks). Main measures: The primary outcome is the Disabilities of the Arm, Shoulder and Hand (DASH). The secondary outcomes are active range of motion (AROM), visual analogue scale (VAS), Tampa Scale for Kinesiophobia, Short Form-12 and Global Rating of Change. Participants were assessed at baseline, after a six-week intervention period and one-month later (follow-up). Results: After treatment, improvement in the mean DASH score was slightly better in the PNF stretching group (8.66 ± 6.15) compared with the static stretching group (19.25 ± 10.30) ( p = 0.03). The overall group-by-time interaction for the 2 × 3 mixed-model analysis of covariance (ANCOVA) was also significant for elbow flexion AROM (mean change for PNF stretching group; static stretching group; 41.10, 34.42, p = 0.04), VAS-rest (–1.31, –1.08, p = 0.03) and VAS-activity (–3.78, –3.47, p = 0.01) in favour of PNF stretching group. The other outcomes did not differ significantly between the two groups. Conclusion: The study demonstrated that the structured exercise programme combined with PNF stretching might be effective in patients with posttraumatic elbow stiffness with regard to improving function, elbow flexion AROM, pain at rest and during activity.

Abstract:
Several studies utilizing adult subjects have indicated that static stretching may reduce subsequent strength and power production, possibly for as long as an hour following the stretch. This observation has not been evaluated in children, nor in athletes accustomed to performing static stretches during strength/power type training sessions. The purpose of this investigation was to determine if an acute bout of passive, static stretching of the lower extremity would affect jumping performance in a group of young, female gymnasts. Thirteen competitive gymnasts (age 13.3 − 2.6 yrs) performed drop jumps under two conditions: immediately following stretching and without prior stretching. The jumps were performed on separate days. The conditions were randomly ordered among the subjects. Time in the air (AIR) and ground contact time (CT) were measured during the drop jumps using a timing mat. Three different stretches of the lower extremity were conducted on each gymnast twice, each stretch being held for 30 seconds. Following the stretching condition, AIR was significantly reduced (.44 vs .46 sec, p < .001), while CT was not different (.130 for both conditions, p > .05). This study demonstrates that children’s lower extremity power is reduced when the performance immediately follows passive, static stretching, even in children accustomed to static stretching during training sessions involving explosive power.

Methods: Forty male subjects were enrolled in study out of which forty male subjects (age group 19-25 years) having ITB tightness defined by active hip adduction test, nobles test and Ober’s test were included and randomly assigned to foam rolling and static stretching groups (20each). Active hip adduction, VAS values measurements pre, mid and post-intervention were taken. Foam rolling: Subject did continuous rolling of ITB on the foam roller, from the ischial tuberosity to the lateral knee for 1minute. Static stretches: For the static stretch the subjects placed their leg behind normal leg with their knee extended and their ankle neutral in standing posture. Subjects were then instructed to lean sideways from the hip, with their spine in neutral until a stretch was felt in the lateral thigh in ROM which were highly significant on analysis Results: Unpaired t-test for comparison of one week findings of both static stretching and foam rolling group showed significant changes with p=0.00, there is significant variation in mean observed for static stretching and foam rolling Conclusion: This study revealed that both foam rolling and Static stretching were effective techniques for increasing hip adduction ROM and reducing pain showing improvement but Foam rolling produced more significant results as compared to static stretching group over a week intervention plan Key words: Myofascial release; active hip adduction; autogenic inhibition; Foam Rolling; Static Stretching .

Abstract:
This study was conducted to investigate the effect of static and dynamic stretching on hamstring muscle flexibility and risk of injury. A total of 20 female students who are in their final year of various departments at the Sultan Idris of Educational University (UPSI) were involved in this study. Subjects were selected based on the body mass index and never active in sports. The will divided into two groups. Group A (n =10) will perform five types of static stretching exercise while the second group B (n = 10) will perform five types of dynamic stretching exercise. They will perform 5-minutes warming up exercise that is jogging before start the stretching. The stretching exercise will handle in three days alternately fo four weeks. The flexibility of the hamstring muscles was measured using a test range protrudes. The instrument that used to measure the flexibility of the hamstring muscles sit reach box, and it is measure before and after the intervention. Pre-test shows no differences between both types of stretching exercise. For the post-test score, static stretching exercise shows the better hamstring flexibility scores than dynamic stretching exercise, t (9) = 23.60, p < 0.005. The results indicated that static stretching exercise is more effective in increasing the hamstring flexibility compared to dynamic stretching exercise and also have results on it in reducing the risk of injury.

Abstract:
Purpose:To examine the acute effect of a single static-stretching session of hamstring muscles on torque production in relation with individual flexibility.Methods:Maximal voluntary concentric torque of hamstring muscles was measured before and after a static-stretching session (6 × 30 s). Torque changes were correlated with the flexibility level determined at the onset of the experimental procedure.Results:The hamstring-stretching intervention significantly reduced maximal concentric torque in participants with low and high hamstring flexibility. Hamstring flexibility and torque decrease, determined immediately after the stretching procedure, were negatively correlated.Conclusions:Torque decrease measured after the static-stretching session is dependent on participant flexibility. Participants with low flexibility are much more likely to demonstrate large torque decreases poststretching.

Abstract:
Objectives The purpose of this study was to examine the time course of changes in the range of motion and muscle-tendon unit stiffness of the hamstrings after two different intensities of static stretching. Methods Fourteen healthy men (20.9 ± 0.7 years, 169.1 ± 7.5cm, 61.6 ± 6.5kg) received static stretching for 60 seconds at two different intensities based on the point of discomfort (100%POD and 120%POD) of each participant, in random order. To evaluate the time course of changes in the flexibility of the hamstrings, the knee extension range of motion (ROM), passive torque at end ROM, and muscle-tendon unit stiffness were measured pre-stretching, post-stretching, and at both 10 and 20 minutes after static stretching. Results For both intensities, ROM and passive torque at pre-stretching were significantly smaller than those at post-stretching (p < 0.01 in both intensities), 10 minutes (p < 0.01 in both intensities), and 20 minutes (p < 0.01 in both intensities). The muscle-tendon unit stiffness at pre-stretching was significantly higher than that at post-stretching (p < 0.01), 10 minutes (p < 0.01), and 20 minutes (p < 0.01) only in the 120%POD, but it showed no change in the 100%POD. Conclusion The results showed that ROM and passive torque increased in both intensities, and the effects continued for at least 20 minutes after stretching regardless of stretching intensity. However, the muscle-tendon unit stiffness of the hamstrings decreased only after static stretching at the intensity of 120%POD, and the effects continued for at least 20 minutes after stretching.

Abstract:
Background and Aims To compare the effect of active and passive static stretching hamstrings on flexibility and lumbar-pelvic rhythm in non-athlete men with hamstring shortness. Clinical observa‌tions have suggested that hamstring tightness influences the lumbar pelvic rhythm and may be associated with modifications in the sagittal spine curvatures during trunk flexion. Thigh hamstring can restrict hip movement, thereby increasing lumbar spine motion and causing back pain due to their influence on spino-pelvic rhythm during forward bending. Methods Hamstring muscle shortness was measured using the SLR and 90-90SLR tests. Measurements of the lumbar pelvic rhythm were recorded in the three-phase forward bending by spinal mouse. Variables include pelvic rotation, lumbar and thorasic flexion. Active and passive static stretching were respectively Jack-knife and kneeling hamstring stretching techniques. To compare pre- test and post- test values of active and passive static stretching groups was used paired t-test and Wilcoxon test. Also to investigate the difference between active and passive static stretching groups was used Ancova and U-Mann Whitney tests. Results After 6 weeks of active and passive static stretching total pelvic rotation was significantly increased in contrast to total lumbar flexion (P0/05). Conclusion Active and passive static stretching could change the lumbo-pelvic rhythm to a pelvic-dominant motion, indicating that flexible hamstring are important for preventing low back pain and other problems associated with disturbance of the lumbo-lumbar rhythm.

Abstract:
Design:Pretest–posttest.Objective:To determine the effect of 4 durations of static hamstring stretching on knee-extension passive range of motion (KE-PROM).Context:Effects of longer (90 and 120 seconds) static hamstring stretching on PROM have not been established relative to more typically recommended 30- or 60-second durations.Subjects:35 healthy college-age subjects with >20° loss of KE-PROM.Outcome Measure:KE-PROM.Intervention:5-week program of single daily stretch for 30, 60, 90, or 120 seconds.Results:Static stretching was effective in increasing KE-PROM regardless of stretch duration (P< .0001). A significant improvement was identified in mean PROM for each stretching group, but no difference existed among the 4 stretch-duration groups. The control group’s mean PROM decreased (mean = -3.2°, SD = 1.9), whereas each stretching group increased PROM (means 1.9° to 3.6°).Conclusions:Five weeks of daily static hamstring stretching for 30, 60, 90, or 120 seconds increase KE-PROM. Similar benefits were achieved regardless of stretch duration, suggesting that clinicians need not perform static hamstring stretches of more than 30 seconds.
