Available in PDF, EPUB and Kindle. Book excerpt: La course à pied et les différentes pratiques sportives induisent des chocs et des vibrations transitoires au niveau des tissus mous à chaque impact. Ces impacts et vibrations peuvent générer un stress mécanique important, qui accroit le risque de fatigue et de blessure de sur-sollicitation. Le premier objectif de la thèse était consacré au développement de méthodes de traitement du signal d'accélération et d'analyse statistique afin de mieux caractériser les impacts et vibrations subies par le sportif. Le second objectif était de définir les facteurs externes, tels que le type de mouvement, le matériel sportif, ou la fatigue neuromusculaire, qui faisaient varier le comportement vibratoire en pratique écologique. Avec le développement de méthodes de traitement du signal (transformée en ondelettes continue) et statistiques (Statistical Parametric Mapping), nous avons montré que la vibration des tissus mous était différente de la vibration musculaire. Ainsi, les accéléromètres ne permettaient de caractériser que partiellement la vibration du muscle par rapport à une échographe ultra rapide. De plus, l'augmentation de la vitesse de course et les mouvements effectués lors de la pratique de sports collectifs génèrent des impacts à plus grande amplitude et à plus haute fréquence, ainsi que des vibrations des tissus mous plus amples que la course en ligne droite. Parmi le matériel sportif évalué, seul un revêtement sportif coulissant a permis de réduire l'amplitude de l'impact au sol. Une identification du type de mouvement a été rendu possible grâce à la mesure des impacts et l'usage d'un réseau de neurones convolutifs, permettant de franchir une première étape dans l'évaluation de la dose vibratoire subie par un sportif lors de sa pratique. Enfin, une étude réalisée lors des courses de l'UTMB a permis d'observer une stratégie de protection de l'organisme après des efforts de type trail en diminuant l'amplitude et la fréquence des vibrations des muscles les plus sollicités. Il reste nécessaire d'améliorer la caractérisation de la vibration musculaire avec des accéléromètres fixés sur la peau et de déterminer l'effet de l'exposition répétée à des vibrations transitoires sur le système neuromusculaire et musculo-squelettique.

Download or read book The Emergence of Pressure Blade Making written by Pierre M. Desrosiers and published by Springer Science & Business Media. This book was released on 2012-03-13 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human development is a long and steady process that began with stone tool making. Because of this skill, humans were able to adapt to climate changes, discover new territories, and invent new technologies. "Pressure knapping" is the common term for one method of creating stone tools, where a larger device or blade specifically made for this purpose is use to press out the stone tool. Pressure knapping was invented in different locations and at different points in time, representing the adoption of the Neolithic way of life in the Old world. Recent research on pressure knapping has led for the first time to a global thesis on this technique. The contributors to this seminal work combine research findings on pressure knapping from different cultures around the globe to develope a cohesive theory. This contributions to this volume represents a significant development to research on pressure knapping, as well as the field of lithic studies in general. This work will be an important reference for anyone studying the Paleolithic, Mesolithic, and Neolithic periods, lithic studies, technologies, and more generally, cultural transmission.
Download or read book Team Sports Training written by Javier Mallo and published by Routledge. This book was released on 2020-03-10 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: Team Sports Training: The Complexity Model presents a novel approach to team sports training, examining football (soccer), rugby, field hockey, basketball, handball and futsal through the paradigm of complexity. Under a traditional prism, these sports have been analyzed using a deterministic perspective, where the constituent dimensions of the sportsmen were independently examined and treated in isolation. It was expected that the body worked as a perfect machine and, once all the components were maximized, the sportsmen improved their performance. If the same closed recipe was applied to all the players that formed part of the squad, the global team performance was expected to be enhanced. As much as these reductionistic models seem coherent, when contrasted in practice we see that the reality of team sports is far more different from the closed conditions in which they were idealized. Team sports contain variable, heterogeneous and non-linear constrains which require the development of a different logic to organize their training. During the last years, ecological psychology, the dynamical systems theory or the constraints-led approach have opened interesting fields of research from which many conceptual foundations can be applied to team sports. Based in this contemporary framework, the current book presents the study of the players and the teams as complex systems, using coordination dynamics to explain the emergence of the self-organisation episodes that characterize them. In addition, this thinking line provides the reader with the ability to apply all these innovative concepts to their practical training scenarios. Altogether, it is intended to challenge the reader to re-think their training strategy and to develop an original theory and practice of training specific to team sports.

Download or read book Fast Handling Technique written by Frank Bethwaite and published by A&C Black. This book was released on 2013-05-12 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the author of the bestselling High Performance Sailing and Higher Performance Sailing comes the first scientific analysis of what makes fast sailors fast. Eschewing the idea that luck or innate talent are the keys to success, Frank Bethwaite shows how knowledge truly is power. Making use of video cameras aligned to GPS read-outs to track the fastest racers, he meticulously analyses what winners do and how they do it, to show the rest of us how to get the best out of a racing craft. Frank Bethwaite's previous books were groundbreaking bibles that applied scientific theories to how sails and hulls interact with wind and water to influence boat speed. But whilst they applied scientific theories to boat construction, they didn't apply science to practical boat handling. This book fills that gap, and then goes further. Budding racers of all levels will welcomethis unique book as a godsend. It will inform, instruct and enable them toemploy the techniques (and timing) of the most successful racers, and make racingmore competitive for participants, and more exciting for those of us watching.
