Physical Activity and Obesity - 2nd Edition

Physical Activity and Obesity, Second Edition, addresses an array of topics that explore and divulge the links between physical activity (or inactivity) and obesity. Leading scientists from various backgrounds team up to provide an unrivaled resource examining the latest research and developments in the field. Each chapter provides researchers and practitioners with a clear explanation of the concepts, research techniques, and results of studies critical to understanding physical activity and the obesity epidemic.

In the 10 years since the first edition of this book was published, the field of physical activity and obesity has mushroomed with new research, sparking the need for not only a new edition but an innovative and refreshing approach to the contents. Editors Bouchard and Katzmarzyk create a go-to resource with 89 succinct, authoritative chapters that may be used independently or as a complete text. Packed with the most up-to-date information linking obesity and physical activity, this comprehensive book

• delves into areas of uncertainty and controversy instead of avoiding them or skirting the issues;

• emphasizes, where appropriate, the underlying mechanisms between physical activity and obesity; and

• points to research areas that need further exploration and attention.

The nine parts of the book flow logically and address obesity in all populations, including children and adults of various backgrounds, ethnicities, and social classes. An overview of the methods used in assessing the levels of sedentary behavior and physical activity is given, followed by a global view of the problem of physical inactivity and obesity. Readers will learn about the key determinants of physical activity levels and obesity and the links between a sedentary lifestyle and the risk of obesity. Other topics examined include behavioral and environmental correlates and determinants of obesity, the relationship between low physical activity energy expenditure and obesity risk, clinical implications, and policy and research issues related to physical activity and obesity.

Physical Activity and Obesity, Second Edition, helps readers better understand the role of physical activity in the overall energy balance equation. The unique format, expert contributors, and complete references make this resource indispensable for researchers, health and exercise practitioners, and students studying the ever-expanding topic of obesity as it relates to physical activity.

The book contains black-and-white illustrations.

The editors of this exceptional text details the costs, causes, and consequences of obesity, along with the role of physical activity in weight control and health. While in-depth, this book is not intended to be completely exhaustive. This first edition was developed to fill a perceived need in the exercise science and sports medicine communities and is meant to encourage those who may pursue a research career in physical activity and obesity. The editor is one of the world's most accomplished researchers in the study of obesity, genetics, and physical activity. The contributing authors represent a collection of leaders from their respective disciplines and have done an admirable job of providing clinicians and researchers alike with an up-to-date review of the research. The first half of this four-section, 19-chapter compilation is dedicated to the present state of obesity (e.g., prevalence, morbidity/mortality, and economic costs) and the biological and behavioral determinants of obesity. In the second half the role of physical activity in the prevention and treatment of obesity in different populations and health and fitness are underscored. In particular, several current and important research questions are addressed, such as: What is the role of physical activity in maintaining weight loss? (Chapter 16) Can obese people be "fat and fit?" (Chapter 18) How can obese people achieve and maintain an active lifestyle? (Chapter 19) In light of 'the obesity epidemic' and the inability of most overweight/obese individuals to maintain weight loss, a greater understanding of these areas is vital. This timely book is presented in a logical, straightforward manner. While some issues arediscussed more than once, the overlap does not detract from the value of the text as a whole. By combining traditional topics with several emerging issues, the editor has made a valuable contribution to the field of physical activity and obesity research.

Claude Bouchard, PhD,

is executive director of the PenningtonBiomedicalResearchCenter in Baton Rouge, Louisiana. For more than 40 years he has researched the role of physical activity on physiology, metabolism, and health indicators, taking into account genetic uniqueness. He also has authored or coauthored more than 1,000 scientific publications, and he served as president of the International Society for the Study of Obesity from 2002 to 2006. He also has served as president of the Canadian Society for Applied Physiology and has directed the Physical Activity Sciences Laboratory at Laval University, Quebec City, Canada, for over 20 years.

Dr. Bouchard has received numerous awards over the years, including the TOPS award from the North American Association for the Study of Obesity in 1998 and the Albert Creff Award in Nutrition of the National Academy of Medicine of France in 1997.

Peter T. Katzmarzyk, PhD,is a professor and the associate executive director for Population Science at the PenningtonBiomedicalResearchCenter in Baton Rouge, Louisiana. He holds the Louisiana Public Facilities Authority endowed chair in nutrition. His main research interest is the epidemiology and public health impact of obesity and physical inactivity, and determining the relationships between physical activity, physical fitness, obesity, and related disorders such as metabolic syndrome, cardiovascular disease, and diabetes.

Dr. Katzmarzyk has published his research findings in more than 190 scholarly journals and books, and he regularly participates in the scientific meetings of several national and international organizations. He is currently an editorial board member for the International Journal of Pediatric Obesity, Journal of Physical Activity and Health, and Metabolic Syndrome and Related Disorders.
