Foundations of Bioenergetics provides an introduction to the physical foundations of bioenergetics and the methods of applying these constructs to biological problems. It combines parts of thermal physics, biochemistry, ecology, and cellular and organismic biology into a single coherent work. Much of the material in this volume comes from ""Entropy for Biologists,"" an introductory thermodynamics book aimed particularly at life scientists. Some of the topics originally appeared in the monograph ""Energy Flow in Biology."" The current volume expands on that material with respect to biological applications and attempts to bridge the gap between physics and biology. The book explains basic concepts such as energy, temperature, the second law of thermodynamics, entropy, information theory, and statistical mechanics. It discusses the relations between thermodynamics and statistical mechanics, free-energy functions, radiant energy, the free energy of cells and tissue, chemical kinetics, and cyclic flows. It examines the relationships between energy flows and biological processes; applications of the concepts of Gibbs free energy, chemical potential, and activity; and measurements of temperature, energy, and thermochemical quantities. The book also includes chapters that deal with irreversible dynamics, irreversible theory, and osmotic flow.

Although there are chapters in exercise physiology texts and a few books on the topics of human bioenergetics and energy metabolism, those chapters and books often do not cover the pertinent information in sufficient detail and are generally highly research oriented or outdated. Bioenergetics Primer for Exercise Scienceis an up-to-date text that encompasses all available information regarding human bioenergetics and energy metabolism and brings together diverse issues that are of theoretical interest and practical importance. Written as a primer, this text explains the foundational and critical knowledge and research findings in bioenergetics and the application of those findings. To evaluate research more knowledgeably and decide which techniques best fit their own research, students and professionals will learn about lab- and field-based techniques used to measure energy metabolism, including lipid metabolism. In addition to bioenergetics concepts and research, the text emphasizes the metabolic challenges brought about by obesity and diabetes. A dedicated chapter discusses metabolic impairments associated with both diseases, alterations in metabolism during exercise for affected individuals, and the role of exercise in enhancing energy utilization and improving glucose response and insulin sensitivity. The text also provides a more specific discussion of bioenergetics applied to the subpopulations of children, elderly people, and women. Without weighing down the reader will highly academic and technical jargon, the text explains the science behind energy metabolism in an accessible and inclusive format specifically designed for exercise science students studying areas other than bioenergetics and professionals working in related areas such as health and fitness, nutrition, and weight management. Bioenergetics novices will appreciate the cohesive presentation of information within a four-part structure: -Part Iillustrates how carbohydrate, fat, and protein are metabolized and converted into energy for sport and physical activity. It conveys basic but critical information before pursuing more advanced topics in bioenergetics. -Part IIpresents lab- and field-based techniques for measuring energy metabolism, including a variety of instrumentations and protocols commonly used to assess energy and fuel utilization. Connections to sport and physical activity, including the energy cost of walking, running, cycling, and resistance exercise, are emphasized. Strategies that can be used to enhance energy utilization with special focus on weight management are also introduced. -Part IIIexplores ideas and strategies for enhancing energy production and expenditure. Metabolic adaptations to exercise training are covered (such as changes in cellular function, fuel utilization, and oxygen uptake after aerobic, anaerobic, and resistance training). Special attention is given to obesity and diabetes, primarily the effect of glucose responses and insulin sensitivity on affected populations and how age, gender, and metabolic diseases affect those populations. -Part IVdiscusses additional aspects of bioenergetics, including factors influencing resting metabolic rate and the thermic effect of food and its relationship to physical activity and obesity. Also included is a discussion of intended use, working mechanism, related research, and potential side effects for select pharmacologic and nutritional substances. Helpful textbook features such as chapter summaries, key point boxes, key terms bolded in the text and defined in the glossary, review questions with an appendix of answers, and an extensive reference list make this text ideal for effective learning and retention for students. More in-depth than cursory discussions found in exercise physiology texts and more practical and accessible than dedicated bioenergetics texts, Bioenergetics Primer for Exercise Scienceencompasses all the up-to-date research and information regarding human bioenergetics and energy metabolism, offering both students and professionals a depth of knowledge that will inform their further study, research, and profession. Bioenergetics Primer for Exercise Scienceis the third volume in Human Kinetics' Primers in Exercise Science Series. This series presents a foundational understanding of the science behind each topic in the series and, when appropriate, its application. Written by leading researchers and teachers in their respective areas of expertise, these books convey the essential concepts in dynamic, complex areas of scientific knowledge using an accessible writing style. Designed for quick reference and ease of assimilation, these books provide students and professionals with up-to-date foundational knowledge in an otherwise unfamiliar scientific area. Other books that have appeared in the series include Biochemistry Primer for Exercise Science, Third Edition,by Michael E. Houston and Genetics Primer for Exercise Science and Healthby Stephen M. Roth.

Despite the fact that many years have elapsed since the first microcalorimetric measurements of an action potential were made, there is still among the research workers involved in the study of bioelectrogenesis a complete overlooking of the most fundamental principle governing any biological phenomenon at the molecular scale of dimension. This is surprising, the more so that the techniques of molecular biology are applied to characterize the proteins forming the ionic conducting sites in living membranes. For reasons that are still obscure to us the molecular aspects of bioelectrogenesis are completely out of the scope of the dynamic aspects of biochemistry. Even if it is sometimes recognized that an action potential is a free energy-consuming, entropy-producing process, the next question that should reasonably arise is never taken into consideration. There is indeed a complete evasion of the problem of biochemical energy coupling thus reducing the bioelectrogenesis to only physical interactions of membrane proteins with the electric field: the inbuilt postulate is that no molecular transformations, in the chemical sense, could be involved.

In the last few years there has been an excltmg upsurge in seabird research. There are several reasons for this. Man's increased ex ploitation of natural resources has led to a greater awareness of the potential conflicts with seabirds, and of the use of seabirds to indicate the damage we might be doing to our environment. Many seabird populations have increased dramatically in numbers and so seem more likely to conflict with man, for example through competition for food or transmission of diseases. Oil exploration and production has resulted in major studies of seabird distributions and ecology in relation to oil pollution. The possibility that seabirds may provide information on fish stock biology is now being critically investigated. Some seabird species have suffered serious declines in numbers and require conservation action to be taken to reduce the chances that they will become extinct. This requires an understanding of the factors determining their population size and dynamics.
