Advanced Exercise Physiology: Essential Concepts and Applications builds upon foundational topics and looks further into key physiological components to help advanced students gain a deeper level of understanding. Authors Jonathan K. Ehrman, Dennis J. Kerrigan, and Steven J. Keteyian address a wide range of complex topics with evidence-based information and a focused, targeted style. The first five chapters offer a detailed examination of the various body systems. The next two chapters focus on exercise testing and training principles, as well as training adaptations as they relate to aerobic power, anaerobic power, range of motion, and resistance training of healthy individuals and competitive athletes. The remaining chapters focus on a variety of topics, including athletic performance, body composition and weight management, and environmental influences of exercise physiology. The final two chapters bring a unique perspective to the book with a review of the relationship between exercise physiology and public health and a look at recent and emerging topics in the field, including genomics and pharmacology. Enhancing the content are learning aids, more than 140 images and illustrations, and practical examples from among clinical patients, healthy individuals, and competitive athletes. Key terms and their definitions appear at the end of each chapter; these help students understand key concepts and serve as a useful reference for practitioners. The appendixes contain information related to topics such as efficiency and energy expenditure, metabolic equivalent (MET) values of common activities, and the professionalization of exercise physiology.

Le sommeil est une fonction biologique basée sur divers groupes de neurones situés à la base du cerveau, et travaillant régulièrement en réseau de manière physiologique. Sous le contrôle de l'hypothalamus et de l'épiphyse (mélatonine), influencés par la lumière, le sommeil est naturellement réglé comme une horloge et démontre d'ailleurs une activité cyclique. Malheureusement, cette fonction peut assez facilement être déréglée au long cours par des modifications environnementales (mauvaises habitudes, médicaments inadéquats, pathologies propres du sommeil type apnées, secousses ...). Le retour à la normale reste généralement possible en revenant dans de bonnes conditions. La prise en charge de notre propre santé passe entre autres par la bonne gestion de la fonction sommeil, particulièrement utile à la bonne maintenance de notre capital « Énergie Physique ». Le sommeil, qui concerne à peu près 1/3 de notre vie, nous apporte outre la récupération physique, d'autres bienfaits, à bien connaître pour notre équilibre de vie, particulièrement au plan immunitaire et aussi émotionnel. Pour ce dernier, le sommeil dit REM, est donc aussi fondamental pour notre capital « Énergie Mentale ». Cet ouvrage nous apprend à le respecter et à bien le gérer, en respectant au mieux l'aspect naturel de cette fonction innée chez chacun d'entre nous est donc fondamental pour toute notre vie.

The benefits of a healthy lifestyle are well documented, yet many people continue to struggle with sedentary behavior and obesity. In Biologic Regulation of Physical Activity, Dr. Thomas W. Rowland posits a distinct possibility of the existence of a central biologic controller of activity. If harnessed, this mechanism could lead to breakthroughs in health science professionals' quest for more effective ways of helping people be more active and, as a result, healthier. Rowland is one of the most well-respected pediatric cardiologists in the United States. He has authored three other books and more than 150 journal articles and has served in several key national leadership positions in pediatric medicine. In Biologic Regulation of Physical Activity, Rowland uses his expertise, along with numerous references and direct quotes from expert witnesses, to provide a detailed account of how current research may support the existence of a biologic regulator--a mechanism in the brain that involuntarily controls biological processes--associated with physical activity. Rowland proposes a possible mechanism for such a control and explores the implications of this theory. This developing area of research and theory offers a new lens through which health professionals and those who research issues related to obesity, physical activity adherence, and sedentary behaviors can view their work. The book moves methodically through the research, rationale, and implications of a biologic regulator of physical activity. In part I, Surveying the Evidence, readers are guided through a litany of research--both on humans and on animals--that provides support for the existence of a biologic regulator. This section synthesizes evidence from an interdisciplinary perspective, covering research on topics such as behavioral disorders, brain damage, lifetime activity patterns, and sex differences. Part II, Rationale and Mechanisms details the possible biologic explanation for control of energy output through activity and proposes a mechanism by which it might function in order to maintain an energy in-energy out balance. The hypothesis presented in this section is that the body has a need for energy balance that leads to activity regulation, similar to how the body regulates appetite. In part III, Implications of Biologic Regulation of Activity, some clear implications from current research, which may help health science professionals in their treatment and prevention efforts against patients' obesity and inactivity, are discussed. Rowland also poses some critical questions for further research, if indeed a biologic controller of activity exists, such as how much effect a biologic controller might have on activity level as compared to environmental factors and whether this biologic regulator could be altered. This book will initiate further discussion, examination, and research into the idea that physical activity may be, at least in part, controlled by a central biologic regulator. Further study may lead to a widespread realization that there is an involuntary biologic regulator of activity that, once fully understood, could lead researchers to discover alternative interventions in the fight against inactivity and obesity.

How can we turn back the clock? Health food, gyms and cosmetic companies promise us everlasting youth, but the effects of aging are caused by complex biological processes at the level of the cell. The author shows what we can do to protect ourselves and what exciting breakthroughs scientists are still working on, and he asks which industries benefit by peddling dubious information and dubious remedies. He also looks at why we are so keen to deny that we are aging, when indeed, aging is a part of life - for everything from bacteria to humans.

Recent advances suggest that the concept of information might hold the key to unravelling the mystery of life's nature and origin. Fresh insights from a broad and authoritative range of articulate and respected experts focus on the transition from matter to life, and hence reconcile the deep conceptual schism between the way we describe physical and biological systems. A unique cross-disciplinary perspective, drawing on expertise from philosophy, biology, chemistry, physics, and cognitive and social sciences, provides a new way to look at the deepest questions of our existence. This book addresses the role of information in life, and how it can make a difference to what we know about the world. Students, researchers, and all those interested in what life is and how it began will gain insights into the nature of life and its origins that touch on nearly every domain of science.

Pourrait-on endurer le pire, si l'on n'attendait le meilleur ? C'est l'interrogation qui relie ces quatre études qui ont pour objet la douleur physique, la douleur morale, la douleur de vieillir, enfin le rapport entre la douleur et l'art. Une telle attente ne sait pas ce qu'elle attend. Le plus souvent, elle s'ignore elle-même. Elle est non un sentiment particulier mais une forme universelle du temps humain. Cette forme, cependant, resterait vide, si l'on ne pouvait identifier plus précisément les contraires du pire. Ils ont ici pour noms parole, mémoire, musique et amour. Envisagés comme des dimensions du soin dû à l'homme souffrant, ils répondent diversement à son appel.
