Abstract:
Introduction: Many athletes perform stretching exercises as part of a warm-up prior to physical activity in order to prevent injuries and enhance their performance by an increase in flexibility. The significance of this study was that it may provide information about the better stretching method between dynamic and PNF stretching immediately before the sports events which may help to enhance the strength of knee extensor, thereby helping in improving performance and injury prevention.Method: An experimental design was used in the study. 51 subjects were randomly divided and statistically analysed for results. Group 1 had to under go dynamic stretching, Group 2 had to undergo PNF stretching for a period of four, and Group 3 (control group) did not undergo any kind of stretching. Results: It was observed that there was no significant difference in peak torque and average torque at 60⁰/s and 180⁰/s and SEBT scores after 4 weeks of dynamic vs PNF stretching. No significant difference was found in dynamic balance after 4 weeks of dynamic vs PNF stretching. Conclusion: We may infer that dynamic stretching and proprioceptive neuromuscular facilitation stretching of antagonist muscle have the same effect on knee extensor torque and dynamic balance in young collegiate males.

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:
"Introduction. Static stretching is generally performed in sport and clinical settings, although dynamic stretching is increasingly being used before exercise and competition. There is strong evidence that a decrease in muscle strength can be the result of longer durations of static stretching, a phenomenon called stretching-induced force deficit. Objectives. The aim of this paper was to determine the jumping power output differences before and after dynamic stretching in young male athletes. Materials and Methods. The participants in this study were young male athletes (N = 18), aged from 14 to 16 years old that underwent two measurements on the MGM-15 carpet. Results. There was a significant statistical difference in the scores between the control and after dynamic stretching conditions. This means that the dynamic stretching had an influence over the power output of the subjects. Conclusion. The results revealed that the power output was significantly improved (increased) after dynamic stretching compared to control measurement. Furthermore, dynamic stretching should be performed in order to increase the power output performances of jumping. Keywords: dynamic stretching, power output, male, athletes, jumping "

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.

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.

The aim of this paper was to determine if the neuromuscular reaction time during jumping is influenced by dynamic stretching. Materials and Methods. The participants in this study were young female basketball players (N = 22), ages from 16 to 18 years old that underwent two measurements using the MGM-15 carpet in two situations: without doing dynamic stretching and after doing dynamic stretching. Results. There was a significant statistical difference in the scores between the control and after dynamic stretching measurements.

Abstract:
The main purpose of this study was to compare the acute effects of static and dynamic stretching in the warm-up, on hamstring flexibility using a reliable set-up for measurement. Static and dynamic flexibility was measured using five modifications of the Straight Leg Raise (SLR) test to measure hip flexion range of motion (ROM). In the first part of the study (n = 33) hamstring flexibility was measured using a Static-passive, Static-active, Dynamic-supine and Dynamic-standing tests. The results of this study were used to calculate reliability statistics and to compare the various static and dynamic flexibility tests. There was a significant difference between Static-passive (SPH) and the Dynamic-supine (DSUH) tests (p less than .05). This was followed by an intervention study (n = 12) where participants were randomly assigned to three intervention treatments of 225 seconds on separate days: No stretching (Treatment I), Static stretching (Treatment 2) and Dynamic stretching (Treatment 3) in a cross-over study design. Static stretching had no impact on dynamic hamstring flexibility; however, dynamic stretching improved dynamic flexibility while simultaneously increasing static flexibility. This has implications for the specificity of stretching in sport.

Abstract:
The purpose of this study was to compare effects of static and dynamic stretching on explosive agility movements, and to examine the effect of the interaction of dynamic and static stretching prior to explosive agility movements. Fourteen men and 10 women performed the different warm-up protocols, including no warm-up (NWU), static stretching (SS), dynamic stretching (DS), and dynamic stretching with static stretching (DS+SS). The T-Drill was used to assess agility. The results indicated no difference between the NWU and SS conditions (effect size = 0.40, p = 0.06), as well as no significant difference between the NWU and DS+SS conditions (effect size = 0.01, p = 0.48), and the SS and DS+SS conditions (effect size = 0.40, p = 0.06). Statistically significant differences were found between the NWU and DS conditions (effect size = 0.45, p = 0.03), the SS and DS conditions (effect size = 0.85, p < 0.001), and the DS and DS+SS conditions (effect size = 0.40, p = 0.03). Agility test times, in order from fastest to slowest, were (a) dynamic stretching (10.87 ± 1.07 s), (b) dynamic stretching + static stretching (11.41 ± 1.26 s), (c) no warm-up (11.42 ± 1.21 s), (d) static stretching (11.90 ±1.35 s). Dynamic stretching resulted in the fastest agility test time. Static stretching resulted in the slowest agility times. The benefits of dynamic stretching may have been diluted when followed by Static Stretching, and the agility test time was the same as if no form of stretching was completed. Static stretching prior to agility is not recommended as it has a negative effect on the stretch shortening cycle, and agility. The results support the use of dynamic stretching prior to agility performance.

Full text
Abstract:
Warm-up routines commonly include stretching to increase flexibility (joint range of motion - ROM), optimise performance, and reduce the risk of injury. Literature suggests that static stretching as part of the warm-up routines decreases force and power production compared to an active warm-up or a warm-up including dynamic stretching, and therefore could be detrimental to performance. This has led to an increased interest in the use of dynamic stretching by many athletes while the benefits of such interventions and their potential mechanisms of action are not well understood. Studies presented in this thesis were conducted to examine the effects of acute dynamic stretching on aspects of performance (e.g. torque production capacity of the plantarflexors and running economy) and to identify possible neuromechanical mechanisms underpinning any potential changes. Furthermore, we attempted to examine whether altered pain tolerance/perception to stretch may be a contributing factor to the increased ROM using adaptations in the neural substrates involved by using functional magnetic resonance imaging (fMRI) technique. In the first study, both slow dynamic stretching and fast dynamic stretching increased ROM, and this was due to an increased tendon elongation. Importantly, dynamic stretching was not detrimental to the torque producing capacity of the ankle plantarflexors. Effects of dynamic stretching on the sensorimotor performance remained mainly unclear. Employment of shear wave elastography technique in the second study suggested an increase in muscle stiffness, a decrease in fascicle strain, and showed an increase in muscle thickness after dynamic stretching, supporting an increase in tendon compliance as a contributing factor to increased flexibility after dynamic stretching. In the third study, the improved running economy by dynamic stretching may be attributable to the decreased dynamic joint ankle and vertical stiffness. The fMRI study was not conclusive due to methodological issues. Present findings have practical implications for the use of dynamic stretching in sporting contexts.

Full text
Abstract:
Post-activation performance enhancement (PAPE) is a phenomenon characterised by the acute enhancement of muscular performance consequent to prior voluntary, dynamic contractile activity, and is the premise underpinning complex training (CT). CT involves alternating a conditioning stimulus (CS) with a lighter load biomechanically similar ballistic exercise (complex-pair), separated by a defined intra-complex recovery interval. One of the key benefits of CT is the ability to train both extremes of the forcevelocity curve within a single training session, offering a potentially efficient and effective means of augmenting both acute explosive muscular performance and chronic training adaptations in maximal strength and power. The challenge for sports practitioners is to design CT protocols that facilitate PAPE of muscular power characteristics of the individual athlete within the constraints of a team sport environment. Consideration of the factors that modulate the expression of PAPE in the design of CT protocols is essential. Specifically, consideration of the mode, volume, and intensity of the CS, the intra-complex and inter-set recovery, and the influence of athlete strength characteristics is required. More importantly, the influence of performing multiple complex-sets, the effect of sequencing lower and upper body complex-sets, and the impact of performing ancillary exercise within the intra-complex recovery on the expression of PAPE warrants attention. Purpose: The primary purpose of this series of studies was to investigate the influence of CT protocol design and the factors that modulate the expression of PAPE of acute explosive performance in developing and trained team sport athletes. Outcomes arising from this work are aimed at providing a practical framework for sports practitioners to better inform the design and implementation of CT protocols in high-performance strength and conditioning programs. Methodology: The first study examined the effect of CS intensity on the magnitude of PAPE of countermovement jump (CMJ) performance over multiple complex-sets and further investigated if athlete relative strength level is a criterion for identifying responders to PAPE. The second experimental study addressed the parameters of CS mode and intensity in CT session design, examining the efficacy of varying load jump squats (JS) on acute drop jump (DJ) performance. Lastly, the third experimental study investigated the effect of CT session design on PAPE of loaded JS and ballistic bench throws (BBT)—more specifically, if manipulating the sequence of upper and lower body complex-sets and interspersing ancillary exercise within the intra-complex recovery period modified the expression of any PAPE. Results: CMJ peak jump height was enhanced in response to both moderate intensity (65% 1-RM) and high intensity (87% 1-RM) conditioning stimuli. PAPE of several DJ kinetic and kinematic variables following JS performed at both 30% and 50% 1-RM back squat loads was observed, however, the frequency and magnitude of PAPE was greatest in athletes following the 30% 1-RM CS load. Small magnitudes of PAPE were observed in various JS and BBT kinetic and kinematic variables in each of the three CT protocols examined, yet no clear or consistent performance benefit was present across sets. Associations between relative strength and PAPE are dependent on CS intensity and CT protocol design. Conclusions: The most important finding of this thesis is that the sequencing of multiple lower and upper body complex-sets and the performance of ancillary exercise within the intra-complex recovery are not detrimental to subsequent explosive performance. Furthermore, PAPE of JS and DJ performance is achievable with a range of CS intensities and appears to be dominant in variables with a prevalent eccentric component. Finally, the influence of relative strength on the expression of PAPE is dependent on CT session design. The application of CT has merit in training team sport athletes and affords practitioners the ability to provide both heavy-resistance and ballistic training stimuli in a time efficient manner.

Abstract:
This study examined the short-term training effects of two volumes of a dynamic warm up performed 4 days per week over a 3 1/2-week period. A total of 25 Division III wrestlers volunteered for the study. Three participants either dropped out or were unable to attend post-testing, resulting in 22 total participants completing the study. Groups were divided into control, low volume, and high volume groups. All participants completed pre and poststudy performance tests including the standing long jump, proagility, start-stop-cut, and 30- meter sprint. The low and high volume training groups each performed the same dynamic warm up prior to each pre-season captain's practice. The control group did not participate in an organized warm up. The low volume group performed one set of each warm up exercise, and the high volume group performing two sets of each warm up exercise. Data analysis indicated significant increases in performance for the standing long jump (p = .011) and start-stop-cut (p = .000) measures among the entire sample population. However, there was no significant difference between the groups in these measures. No significant results were found either for the sample as a whole or between groups for the proagility and 30-meter measures. The increased performance of all groups, including the control group, fails to provide evidence for the effectiveness of training with either warm up volume. Further research is needed to address limitations of this study to determine effectiveness of various warm up volumes.

Abstract:
Though much work has studied organizational identity and the management of innovation, very little work explores the connection between them. Yet we argue that these separate conversations yield implications for one another and offer a rich area for future research. By its nature, innovation is about novelty and change, while identity is rooted in stability and endurance. This contrast creates a fundamental tension, which we explore. We propose that innovative activities like technological change fall on a spectrum from identity-enhancing to identity-stretching to identity-challenging. Both identity-enhancing and identity-stretching innovations result in a mutually constitutive dynamic in which identity and innovation reinforce each other. Identity-challenging innovations, however, create organizational discord and dysfunctional dynamics unless realigned with identity. We discuss the implications of these varying states and call for future research that builds upon and extends our understanding of the relationship between identity and innovation across multiple levels of analysis.

Abstract:
Alaska’s central gulf coast encompasses four environmentally diverse regions stretching from Prince William Sound to the Pacific coast of the Alaska Peninsula. Despite their unique geographic and biological settings, these regions have a distinct and cohesive cultural history. Here, the historic distribution of Alutiiq or Sugpiaq peoples reflects the distribution of prehistoric cultures, illustrating a broadly unified evolutionary trajectory. Archaeological data from the past 4,000 years suggest the development of prosperous, permanent villages from smaller, more fluid foraging communities through human ingenuity—the ability to harvest resources with increasing efficiency and to manage inevitable fluctuations in the availability of foods and raw materials in a productive but dynamic environment. Together, changes in climate, population growth, technological innovation, and interaction with other peoples shaped the central gulf’s ancient societies into the powerful corporate groups recorded historically.

Abstract:
This chapter makes the case that institutional and paradox theorists should consider problems stretching beyond managerial concerns and corporate performance to focus attention on the paradoxes that characterize the most deep-rooted and contentious social issues facing societies and economies, suggesting a switch from organizational to institutional paradoxes. To illustrate, two vignettes are described—one focused on the legacy of the University of Georgetown’s slave-trading past, the other on the identity challenges faced by working-class people attending Cambridge University. Drawing from these vignettes, three sets of theoretical insights are presented which are fundamental to institutional paradox: that institutional paradoxes may be rooted in a desire for legitimacy; that temporality is a dynamic at the core of institutional paradox; and that the metaphor of multiple interconnected fault lines better captures the complexity inherent in paradox at the institutional level than the metaphor of dualities.

Abstract:
This book presents a comprehensive overview of the foundations of single-molecule studies, based on manipulation of the molecules and observation of these with fluorescent probes. It first discusses the forces present at the single-molecule scale, the methods to manipulate them, and their pros and cons. It goes on to present an introduction to single-molecule fluorescent studies based on a quantum description of absorption and emission of radiation due to Einstein. Various considerations in the study of single molecules are introduced (including signal to noise, non-radiative decay, triplet states, etc.) and some novel super-resolution methods are sketched. The elastic and dynamic properties of polymers, their relation to experiments on DNA and RNA, and the structural transitions observed in those molecules upon stretching, twisting, and unzipping are presented. The use of these single-molecule approaches for the investigation of DNA–protein interactions is highlighted via the study of DNA and RNA polymerases, helicases, and topoisomerases. Beyond the confirmation of expected mechanisms (e.g., the relaxation of DNA torsion by topoisomerases in quantized steps) and the discovery of unexpected ones (e.g., strand-switching by helicases, DNA scrunching by RNA polymerases, and chiral discrimination by bacterial topoII), these approaches have also fostered novel (third generation) sequencing technologies.

Abstract:
Millions of years ago, the North American continent was dragged over the world's largest continental hotspot, a huge column of hot and molten rock rising from the Earth's interior that traced a 50-mile wide, 500-mile-long path northeastward across Idaho. Generating cataclysmic volcanic eruptions and large earthquakes, the hotspot helped lift the Yellowstone Plateau to more than 7,000 feet and pushed the northern Rockies to new heights, forming unusually large glaciers to carve the landscape. It also created the jewel of the U.S. national park system: Yellowstone. Meanwhile, forces stretching apart the western U.S. created the mountainous glory of Grand Teton National Park. These two parks, with their majestic mountains, dazzling geysers, and picturesque hot springs, are windows into the Earth's interior, revealing the violent power of the dynamic processes within. Smith and Siegel offer expert guidance through this awe-inspiring terrain, bringing to life the grandeur of these geologic phenomena as they reveal the forces that have shaped--and continue to shape--the greater Yellowstone-Teton region. Over seventy illustrations--including fifty-two in full color--illuminate the breathtaking beauty of the landscape, while two final chapters provide driving tours of the parks to help visitors enjoy and understand the regions wonders. Fascinating and informative, this book affords us a striking new perspective on Earth's creative forces.

Abstract:
This paper describes the dynamic response of minimum facilities with different structural configurations which are subjected to random seas. The finite element models are kept simple with the aim of focusing on the physics of the phenomena involved. The response is studied in terms of the dynamic amplification factor (DAF), representing the ratio between the dynamic and the static response. Two different formulations of the DAF under random seas are compared. The first is defined in terms of standard deviation (DAF1), the second in terms of the most probable maximum value (DAF2). Ringing is observed to be a relevant feature of the dynamic response and to affect primarily the braced monopod configurations. Ringing is detected using DAF2. The paper also addresses the importance of the kinematic representation above the still water level. Different methods of stretching the velocity field in the wave zone (delta, Wheeler and exponential stretching) are shown to have a significant impact on the dynamic response of the platforms.

Abstract:
During their lifetime, marine structures and ships are frequently exposed to severe weather and rough, sometimes extreme sea states. To ensure survival, the precise knowledge of global and local loads is an inevitable integral prerequisite for the design of safe offshore structures and marine vessels. Wave-structure interaction and the associated pressure induced wave loads are key parameters for the definition of design load cases. Once the complete surrounding sea state for the identified load condition is known, the pressure induced loads can be computed by calculating the pressure distribution along the hull, using an appropriate wave theory. As 1st-order AIRY-Theory as well as 2nd- and 3rd-order STOKES-Theory excessively overestimate the dynamic pressure above still water level, especially in high wave crests, a variety of stretching terms has been applied to common wave theories to correct the pressure distribution. This paper presents a second-order stretching approach to describe the distribution of the dynamic pressure in regular wave crests. In combination with FFT (Fast Fourier Transformation), the applicability of this method can be extended to irregular sea states and even extreme waves. Calculations for several regular and irregular sea states are shown and compared to calculations with existing stretching methods. The results are validated by measurements conducted in a wave tank at the Technical University Berlin. The paper concludes with an example for the calculation of the wave induced pressure field along a ship hull operating in a short-crested, multidirectional sea state.
