This book was released on 2010 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to examine the effects of landing on a combined inverted and plantarflexed surface on the ankle kinematics and electromyographic (EMG) activities of the medial gastrocnemius (MG), peroneal longus (PL) and anterior tibialis muscles (TA). Twelve recreational athletes performed five drop landings from an overhead bar of 30 cm height on to each of these surfaces: a flat surface, a 25° inversion surface (inverted), and a combined surface (combined) of 25° inversion and 25° plantarflexion. The three dimensional kinematic variables and integrated EMG (IEMG) of the three muscles were assessed using one-way repeated measures analysis of variance (ANOVA, p

This book was released on 2005-06-27 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inhaltsangabe:Abstract: Probably one of the main contributions of this thesis has been the use of a three-dimensional kinematic model accounting not only for ankle motion but also for the motion of the lateral and medial columns of the forefoot with regard to the rearfoot (Arampatzis et al., 2002), in a joint stability context. The obtained values may serve as reference for the planning of further studies and provide a base for building up new hypotheses. However this thesis did not aim to merely describe the kinematics but rather to provide more knowledge regarding the stabilisation of the foot and the ankle. Therefore another important contribution is surely the simultaneous study of the kinematics, the EMG and the ground reaction forces, which allows a better understanding of the whole stabilisation process. The presented results have shown that forefoot motion is fundamental in foot and ankle stabilisation. The flexibility of the forefoot, especially in the frontal plane, permits a fast and appropriate adaptation to the ground. Furthermore the high mobility of the forefoot, allows the ankle to rotate slower and to a lesser extent. Possibly this reduction in required ankle motion can contribute considerably to injury prevention, since the forces acting at the ankle are high and a misalignment with regard to the ground reaction forces could rapidly lead to moments overwhelming the stabilising potential of the involved structures. In addition, the rapid adaptation of the forefoot to the ground can potentially provide more precise and earlier feedback regarding the ground characteristics than the structures surrounding the ankle joint. This way the corresponding adjustments in an immediate feedback could happen earlier, and the consequences of future interactions could be predicted more accurately. The results from the presented studies support the notion that joint stabilisation does not rely primarily on proprioception. Prolonged peroneal latencies might in fact be due to deafferentiation consequent to the recurrent sprains. However prolonged latencies do not seem to be responsible for a functional instability. On one hand the differences in latency times between healthy and unstable ankles are relatively low and not consistently observed. Those studies identifying prolonged latencies in functionally unstable joints, report differences close to 15 ms (Konradsen and Ravn, 1990; Löfvenberg et al., 1995). Fifteen ms is a short time to have a high [...]

Download or read book Biomechanics of Skeletal Muscles written by Vladimir M. Zatsiorsky and published by Human Kinetics. This book was released on 2012-04-10 with total page 571 pages. Available in PDF, EPUB and Kindle. Book excerpt: Richly illustrated and presented in clear, concise language, Biomechanics of Skeletal Muscles is an essential resource for those seeking advanced knowledge of muscle biomechanics. Written by leading experts Vladimir Zatsiorsky and Boris Prilutsky, the text is one of the few to look at muscle biomechanics in its entirety—from muscle fibers to muscle coordination—making it a unique contribution to the field. Using a blend of experimental evidence and mechanical models, Biomechanics of Skeletal Muscles provides an explanation of whole muscle biomechanics at work in the body in motion. The book first addresses the mechanical behavior of single muscles—from the sarcomere level up to the entire muscle. The architecture of human muscle, the mechanical properties of tendons and passive muscles, the biomechanics of active muscles, and the force transmission and shock absorption aspects of muscle are explored in detail. Next, the various issues of muscle functioning during human motion are addressed. The transformation from muscle force to joint movements, two-joint muscle function, eccentric muscle action, and muscle coordination are analyzed. This advanced text assumes some knowledge of algebra and calculus; however, the emphasis is on understanding physical concepts. Higher-level computational descriptions are placed in special sections in the later chapters of the book, allowing those with a strong mathematical background to explore this material in more detail. Readers who choose to skip over these sections will find that the book still provides a strong conceptual understanding of advanced topics. Biomechanics of Skeletal Muscles also contains numerous special features that facilitate readers’ comprehension of the topics presented. More than 300 illustrations and accompanying explanations provide an extensive visual representation of muscle biomechanics. Refresher sidebars offer brief reminders of mathematical and biomechanical concepts, and From the Literature sidebars present practical examples that illustrate the concepts under discussion. Chapter summaries and review questions provide an opportunity for reflection and self-testing, and reference lists at the end of each chapter provide a starting point for further study. Biomechanics of Skeletal Muscles offers a thorough explanation of whole muscle biomechanics, bridging the gap between foundational biomechanics texts and scientific literature. With the information found in this text, readers can prepare themselves to better understand the latest in cutting-edge research. Biomechanics of Skeletal Muscles is the third volume in the Biomechanics of Human Motion series. Advanced readers in human movement science gain a comprehensive understanding of the biomechanics of human motion as presented by one of the world’s foremost researchers on the subject, Dr. Vladimir Zatsiorsky. The series begins with Kinematics of Human Motion, which details human body positioning and movement in three dimensions; continues with Kinetics of Human Motion, which examines the forces that create body motion and their effects; and concludes with Biomechanics of Skeletal Muscles, which explains the action of the biological motors that exert force and produce mechanical work during human movement.
