This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This study aimed to extend the knowledge on player and surface loading by contributing new data in relation to a greater range of movements, relevant in-game scenarios and on carefully controlled third generation artificial turf surfaces. This was done by selecting soccer relevant movements and in-game scenarios for a player movement study with the help of a player focus group and questionnaire. Furthermore, four surfaces were created with surface hardness and rotational traction values at the upper and lower limits of the standards set by FIFA. The study showed that both the surface hardness and rotational traction properties can affect the human movement dynamics, though these effects were mainly present during the stop and turn manoeuvre. During the stop and turn manoeuvre the soft and high traction surfaces conditions led to increased frontal plane moments as well as increased average ground reaction forces during mid-stance. In combination with decreased ground contact times it appeared that the players were able to decelerate / accelerate faster and generate a larger force on the soft and high traction surfaces. During peak push off it appeared that the players were able to generate a larger force on the hard surfaces, which also led to a significant increase in plantar flexion moment. While some parameters showed an effect for surface hardness and / or rotational traction across all four surface conditions, for others such as the knee valgus, hip extension and hip internal rotation moment showed only a significant effect between two of the four surfaces. At the same time the other surfaces showed either no effect or the opposite effect. This suggests that the effects of the surface hardness can be influenced by the rotational traction properties, and vice versa. Regarding the jumping / heading manoeuvre the effects of the surface conditions were limited. This may have been related to the high demands of the movement, or to limitations of the mechanical measurement methods. In addition to the effects of surface properties on human movement dynamics the study also showed that the mechanical measurement methods may not be representative of the human loading. The impact force conditions of the advanced artificial athlete were substantially different to that of the stop and turn and jumping / heading manoeuvre. Whereas for the rotational traction test the study showed that the rotation of the foot during the ST was substantially less than the minimum 45° required by the FIFA guidelines. Regarding the inclusion of in-game scenarios the study showed that both the simulated opponent used for the stop and turn manoeuvre, and heading a ball during a maximal vertical stop jump manoeuvre can affect the human movement dynamics. During the stop and turn with a simulated opponent the frontal plane moments in the lower limbs were significantly increased. However, this increase in joint loading could not be related to any changes in movement strategy. During the landing after heading a ball during a maximal vertical stop jump the players used a different landing strategy by landing in a more upright position and increasing the ankle plantar flexion ankle just before lading. This allowed for a larger change in the ankle plantar / dorsi flexion angle to absorb the impact of the landing. In addition to this, the heading manoeuvre also led to a significant increase in the frontal plane joint moments of the lower limbs. For future studies it is recommended that a combination of surface properties is used to gain insight into how these affect each other regarding the effects they have on human movement dynamics. In addition, they should provide detailed information on the surface design as well as the properties. Regarding the quantification of the properties it is recommended that in addition to industry standards the surfaces are also quantified using conditions closer to those expected within the study. It is also recommended that future studies incorporate in-game scenarios in order to gain more insight into the effects of interventions that simulate actual match situations.

Book excerpt: The playing surface has a great influence on the outcome of a sport. It has a significant effect on the ball behaviour and the technical performance of skills of the sports participants, but it also impacts on their safety. This research is focused on the interaction of humans with natural turf pitches (NTPs). The project research integrates human body, and soil, mechanics in a laboratory environment by means of new technology and methodology to provide new understanding of this interaction. In a biomechanical study carried out using a portable pitch system, stresses and movements for nine male players performing running and turning movements on sand-based and clay-based NTPs revealed significantly greater peak vertical rate-of-loadings (dFz max) and peak pressure rate-of-loadings (dP max) for the sand compared to the clay-based condition. A further soil mechanical study to determine how the dynamic inputs from players affected the behaviour of those surfaces concluded that soil mechanical parameters such as moisture content and dry bulk density have a significant effect on the dynamic stiffness of the surface and that sand-based pitches have a significantly greater intrinsic stiffness than clay-based pitches explaining the observed biomechanical loading rate results. The research provides a step forward in the attempt to understand how humans interact with sports surfaces and how the surfaces respond. It highlights the importance of the elastic-plastic stress-strain behaviour of soils (or the soil-turf matrix) in response to stresses applied by humans and the difference in mechanical behaviour between sand and clay-based pitches. The findings of this research will inform sports engineers about the advantages of integrating biomechanical and soil mechanical data and lead them to ensure that surfaces that are safe to play and do not hinder the quality of the game by providing reasonable wear resistance, stiffness and traction values.

Download or read book The Biomechanical Interaction Between Sports Players and Artificial Turf for the Development of a Validated Artificial Turf Testing Rig written by Steven Blackburn and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Artificial turf is increasingly becoming prevalent in field sports traditionally played on natural grass surfaces. However, current artificial turf test methods are not biomechanically representative. This study investigated the interaction between players and sports surfaces in order to develop a new biomechanically valid testing rig for the mechanical characterisation of artificial turf. A biomechanical analysis of thirteen sports players performing five running and turning movements on three types of artificial turf was conducted. Three-dimensional ground loadings (ground reaction forces (GRFs), free moment) and knee biomechanics (angles, moments) were measured. A subset of eight subjects who completed trials on all three tyes of surfaces were included in statistical analyses. There were no significant differences in ground loadings or knee biomechanics between the turfs. However, ground loadings and knee biomechanics varied significantly between movements, according to movement velocity and the degree of turn. Larger vertical GRFs, peak knee flexion, and sagittal knee moments were measured in faster movements. Larger horizontal GRFs, free moment, traction coefficient, peak fontal knee angle, frontal and transverse knee moment were measured in turning movements. Using two weighted pendulums, the Strathclyde Sports Turf Testing Rig (SSTTR) can apply simultaneous vertical, horizontal and rotational loads. Initial testing of the rig was conducted in situ on nine outdoor artificial turfs. Linear and rotational traction, and vertical, shear and torque loading was measured on each surface and compared with the biomechanical results. The SSTTR produced loads typical of a range of sports movement that are performed on artificial turf, indicating that the biomechanical validity of the SSTTR was broadly demonstrated in that it applies realistic biomechanical loads in a timely fashion. In summary, this study has generated new knowledge and further understanding regarding the three-dimensional biomechanical interaction of players and artificial turf. The biomechanically validated SSTTR is unique in terms of its ability to combine three load actions of different magnitudes which are truly representative of the loading that occur in a number of typical sporting movements.

Download or read book The Architecture and Biology of Soils written by Karl Ritz and published by CABI. This book was released on 2011 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil is a fundamental and critical component of terrestrial ecosystems, but one that is often overlooked. It is an extremely complex environment, both in terms of its physical structure and in that it supports levels of biodiversity far greater than those found above ground in any ecosystem. Bringing together existing knowledge across many areas of soil biology and physics, this book develops the concept of soil architecture and explores key characteristics of the remarkable `inner space' of the soil. The authors consider how such structure develops through time and the consequences this has for life underground. They also explore the interactions between the biological and physical components of the soil and how they relate to its many functions, in order to demonstrate the key role of soil architecture in underpinning ecosystem dynamics. The diverse but richly interrelated perspectives offered in this book make it an essential resource for researchers and students in soil and environmental sciences, terrestrial ecology, plant sciences and microbiology.

Download or read book Sports Related Concussions in Youth written by National Research Council and published by National Academies Press. This book was released on 2014-02-04 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past decade, few subjects at the intersection of medicine and sports have generated as much public interest as sports-related concussions - especially among youth. Despite growing awareness of sports-related concussions and campaigns to educate athletes, coaches, physicians, and parents of young athletes about concussion recognition and management, confusion and controversy persist in many areas. Currently, diagnosis is based primarily on the symptoms reported by the individual rather than on objective diagnostic markers, and there is little empirical evidence for the optimal degree and duration of physical rest needed to promote recovery or the best timing and approach for returning to full physical activity. Sports-Related Concussions in Youth: Improving the Science, Changing the Culture reviews the science of sports-related concussions in youth from elementary school through young adulthood, as well as in military personnel and their dependents. This report recommends actions that can be taken by a range of audiences - including research funding agencies, legislatures, state and school superintendents and athletic directors, military organizations, and equipment manufacturers, as well as youth who participate in sports and their parents - to improve what is known about concussions and to reduce their occurrence. Sports-Related Concussions in Youth finds that while some studies provide useful information, much remains unknown about the extent of concussions in youth; how to diagnose, manage, and prevent concussions; and the short- and long-term consequences of concussions as well as repetitive head impacts that do not result in concussion symptoms. The culture of sports negatively influences athletes' self-reporting of concussion symptoms and their adherence to return-to-play guidance. Athletes, their teammates, and, in some cases, coaches and parents may not fully appreciate the health threats posed by concussions. Similarly, military recruits are immersed in a culture that includes devotion to duty and service before self, and the critical nature of concussions may often go unheeded. According to Sports-Related Concussions in Youth, if the youth sports community can adopt the belief that concussions are serious injuries and emphasize care for players with concussions until they are fully recovered, then the culture in which these athletes perform and compete will become much safer. Improving understanding of the extent, causes, effects, and prevention of sports-related concussions is vitally important for the health and well-being of youth athletes. The findings and recommendations in this report set a direction for research to reach this goal.
