Effect of Static and Dynamic Stretching on Knee Muscle Strength in Trained Players
Bagcilar Medical Bulletin, 2020
The study examined the effects of two different stretching exercises on knee muscle strength in basketball players in order to determine the most appropriate pre-competition protocols for basketball conditioning. Method: Thirty-two basketball players (mean age 22.75±2.73 years, weight 87.47±10.99 kg, height 188.85±7.35 cm, body mass index 24.46±1.89) participated in this study. They performed two different stretching protocols according to basketball training experience in randomly assigned order: randomized in consecutive manner according to admission order, well-trained basketball players (training frequency = 5 days/week, groups I and II), less-trained basketball players (1 day/week, groups III and IV). Basketball players in groups I and III were exposed to isokinetic tests-one each after dynamic stretching and, 1 week later, after static stretching. In groups II and IV, similar evaluations were made after static stretching and, 1 week later, after dynamic stretching. Five days/ week were included in the well-trained group. The less-trained group consisted of basketball players who trained 1 day/week. Results: In less-trained basketball players, static stretching resulted in higher extensor muscular strength and endurance values, whereas dynamic stretching increased knee flexor strength and endurance. Conclusion: Our results suggest that before competitions, stretching exercises should be chosen depending on the conditioning of the basketball player (well-trained, less-trained). Including both static and dynamic stretching into the "stretching" concept seems effective.
Effects of Static and Dynamic Stretching on Sprint and Jump Performance in Boys and Girls
Journal of Strength and Conditioning Research, 2014
The aims of this study were to compare the acute effects of static and dynamic stretching on explosive power, flexibility and sprinting ability on adolescent boys and girls and to compare any differences due to gender. Forty-eight active adolescent boys and girls were randomly tested after static and dynamic stretching for 40 s on quadriceps, hamstrings, hip extensors and plantar flexors; in the control condition they do not performed no stretching. Pre-and post-treatment tests were performed to examine the effects of stretching on 20 m sprint run (20SR), counter movement jump height (CMJ) and seat and reach flexibility test (SR). Static stretching hindered 20SR and CMJ by 2.5% and 6.3% respectively, whereas improved SR by 12.1%.Dynamic stretching hindered 20SR and CMJ by 0.8% and 2.2% respectively, whereas improved SR by 6.5%. Dynamic stretching produces less reduction in 20SR and CMJ than static stretching; however the effect on SR was reverse. The acute effects of static stretching on 20SR and SR were grater in girls than boys, whereas dynamic stretching produced greater changes in SR for girls than boys. It can therefore be concluded that stretching produces significant reduction on explosive power and sprinting performances in adolescent boys and girls.

The aim of the present trial was to investigate the effect of two stretching programs, a dynamic and a static one, on the sprint ability of recreational volleyball players. The sample consisted of 27 male recreational volleyball players (age 21.6 ± 2.1 years, mean ± standard deviation, body mass 80.3 ± 8.9 kg, height 1.82 ± 0.06 m, body mass index 24.3 ± 2.5 kg.m−2, volleyball experience 7.7 ± 2.9 years). Participants were randomly divided into three groups: (a) the first performing dynamic stretching exercises three times per week, (b) the second following a static stretching protocol on the same frequency, and (c) the third being the control group, abstaining from any stretching protocol. The duration of the stretching exercise intervention period was 6 weeks, with all groups performing baseline and final field sprinting tests at 4.5 and 9 m. The post-test sprint times were faster in both the 4.5 (p = 0.027, η2 = 0.188) and 9 m tests (p < 0.001, η2 = 0.605) compared to the pre-...
Effect Of Acute Dynamic And Static Stretching On Maximal Muscular Power In Recreational Athletes
2016
Stretching promotes increased ROM, muscle temperature, and decreased stiffness of the exercised muscle. It reduces the risk of injury, alleviates pain, and improves athletic performance. The most common stretching types used prior to exercise are static and dynamic. By identifying the most beneficial type of stretching for a given exercise bout, therapists can utilize techniques to enhance stretches as they relate to strength and power performance. The purpose of this study was to determine the acute effect of dynamic and static stretching on maximal muscular power which is evaluated by peak jump height in college age recreational athletes.60 participantsmeeting the inclusion and exclusion criteria were allocated into 3 groups 20 each. Group A: Warm up+Dynamic Stretching, Group B: Warm up+Static Stretching, Group C: [Control group]: Warm up+no stretching. Stretching of Gluteus maximus, Quadriceps, Hamstrings, Hip flexors, Dorsiflexors, Latissimus dorsi were done. Pre intervention ve...

The purpose of this study was to examine the acute effects of static stretching (SS) and dynamic stretching (DS), alone and in combination with specific basketball warm-up (SBWU), on the neuromuscular excitability and vertical jump height in basketball players. Twelve healthy young male basketball players participated in the study (18 ± 0.42 years; 17.4 - 18.6 age range; 188 ± 9 cm; 76.5 ± 9 kg). All participants completed two different stretching treatments (static and dynamic), performed on different days at least seven days apart, in the same period of training microcycle, in a counterbalanced order. Each session consisted of a self-paced jogging warm-up, followed by a 10-minute testing period (T0), which involved eliciting H reflex and M waves, followed by three trials of a vertical jump test. Participants then performed one of the treatment protocols. After another test (T1), participants conducted 8-minute specific basketball warm-up and then one more test (T2). Combined 3 (ti...
Sport Sciences for Health
Objective: This study examined the effects of 8 weeks stretch-shortening-cycle-based (SSC-based) versus non-SSC-based jump exercises on physical fitness in prepubertal male soccer players. Methods: Twenty-six participants were randomly assigned to either a SSC-based using countermovement-jump (CMJG; n=13) or a non-SSC-based jump group using squat-jump (SJG; n=13). Pre-and post-training, tests were conducted to assess measures of muscle power (countermovement-jump, reactive-strength-index), speed (5-m, 20-m), change-of-direction (CoD), and sport-specific performance (maximal-kicking-distance). To establish the effect of the interventions on the dependent variables, a 2 (group: CMJG and SJG) × 2 (time: pre, post) ANOVA with repeated measures was determined for each parameter. Results: Findings demonstrated a main effect of time for countermovement-jump, reactive-strength-index, and maximal-kickingdistance (p<0.05, effect size [ES]=0.56-0.71). Group × time interactions were identified for (5-m, 20-m, and reactive-strength-index (p<0.05, ES=0.59-0.64) in favor of CMJG. Particularly, pre-post performance improvements have been observed for 5-m (∆1.6%; p=0.04; ES=0.54) and 20-m (∆5.3%; p<0.01; ES=1.00) in the CMJG. For SJG, 5-m (∆-5.5%; p=0.01; ES=-1.12) and 20-m (∆-3.7%; p=0.01; ES=-0.82) pre-post performance declines were observed. Regarding reactive strength index, pre-post improvement was noted for CMJG only (∆-40.1%; p<0.01; ES=3.7). In addition, a tendency toward a group × time interaction was found for CoD (p=0.06, ES=0.54) with a performance decrement for SJG (∆-6.0%; p<0.01; ES=-1.8) and no pre-post changes for CMJG (∆0.15%; p>0.05; ES=0.05). Conclusion: Overall, jump exercises which utilise the SSC seem to be more effective in improving measures of speed and muscle power performance in young athletes. However, jump exercises that do not involve the SSC appear to negatively affect CoD performance in young athletes.
Effect of Different Stretching Protocols on Vertical Jump Performance
2018
This study aimed to examine the effect of different stretching exercises on vertical jump performance. A total of 14 national male athletes sporting in the elite level took part in the study. The age average of the participants was 20.25±1.03 year, the average height was 1.80±.08 m, the average body weight was 77.14±18.91 kg, average of sporting age was 9.87±3.31 year and the average number of participation in international games was 10.0±3.31.

The vertical jump performance before and after different stretching exercises of the participants was determined by means of the ...
Flexibility responses to different stretching methods in young elite basketball players
Muscles, Ligaments and Tendons Journal, 2017
Introduction: The aims of study were: 1) to verify the effectiveness of different stretching methods and training; 2) to compare the effects with only training on the flexibility of joints in basketball players. Methods: 30 males basketball players (age: 17±1yrs; BMI: 23.4±3.1), divided into 2 groups (15 experimental group-EG-and 15 control group, CG), participated to study. EG performed 5 different stretching method: passive stretching, active stretching, postural protocol, PNF and dynamic stretching. To assess differences (p<0.05) between groups, an ANOVA was applied to anthropometrics characteristic (age; height; weight and BMI) and flexibility performances (leg raise in a supine position; forward trunk bending). ANOVA for repeated measurements was conducted to asses differences in each group with time (i.e., pre-post). Results: Results showed a variation linked to time (F=21.9; p<0.0001) and an effect of the treatment of the leg raise in a supine position test (F=25.1; p<0.0001). Also in flexion test of trunk, the average values could be linked to time of measurement (F=9.96; p<0.0001) and group (F=8.65; p<0.0001). Conclusion: The results suggest that a specific different stretching protocol should be used in different part of body to offer performance benefit and decreasing of the incidents of injuries. Level of evidence: IV.
Effects of Stretching on Jumping Performance
2005
Stretching has been a part of warm-up for a very long time. Some recent research has shown that stretching could possibly hinder performance and others have shown it enhances performance. The purpose of this study was to examine whether stretching has an effect on vertical jump, and if so, how long the effects last. Twenty Western Kentucky students (10 M and 10 F) performed three trials each. There was a non-stretching group, a pre-stretching group and a between-stretching group; each of the subjects performed all three. The stretching protocol included a static stretching routine of the gluteus maximus, hamstrings, quadriceps, and triceps surae. This stretching protocol lasted 7 minutes. The non-stretching group did not stretch, they performed two jump tests; the pre-stretching group stretched first and then performed the two jump tests; and the between-stretching group did the first jump test, stretched and performed the final jump test. Subjects were randomly selected for order of performance in each trial. Results showed a significant difference (p < 0.05) in pre-stretching group reaction time 1 versus reaction time 2 (p = 0.035) and a significant difference in the between-stretching group jump height 1 versus jump height 2 (p = 0.004). There were no other significant differences. This suggests that stretching hinders reaction time and the height of a vertical jump.
Acute Effect of Different Combined Stretching Methods on Acceleration and Speed in Soccer Players
Journal of Human Kinetics, 2016
The 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 difference...
