Human Physical Fitness And Activity

​The science of human physical activity and fitness is ripe for a novel theoretical framework that can integrate the ecological, genetic, physiological and psychological factors that influence physical activity in humans. Physical inactivity dominates most developed nations around the world, and is among the leading causes of disease burden and death worldwide. Despite the wide array of physical and mental health benefits, few people get the recommended level of physical activity to achieve these benefits. Current research on physical activity has not, as of yet, been successful for the development of effective exercise interventions. Several researchers have advocated a more integrative approach that takes evolutionary history into account, but such a framework has yet to be advanced. To that aim, the first goal of this book is to present a comprehensive evolutionary and life history framework that highlights the domain-specific aspects of the evolved psychology and physiology that can lead to a more integrated and complete understanding of physical activity across the lifespan. It summarizes and extends previous work that has been done to understand the ways natural selection has shaped physical activity in humans in traditional and modern economies and environments. In many ways, humans are adapted to be physically active. Overall, however, natural selection has shaped a flexible, but energy conscious system that responds to environmental and individual costs and benefits of physical activity to optimally allocate a finite energetic budget across the lifespan. This system is adapted to respond to cues of resource scarcity and high levels of obligatory physical activity, and conserves energy to favor allocation in ways that increase the likelihood of reproductive success and survival. This nuanced application leads to a more thorough understanding of the circumstances that natural selection is predicted to favor both sedentary and active behaviors in predictable ways across the lifespan. The second goal of this book is to synthesize and interpret cross-disciplinary research (from biological and evolutionary anthropology and psychology; epidemiology; health psychology; and exercise physiology) that can illuminate original approaches to increase physical activity in modern, primarily sedentary contexts. This includes a breakdown of the human lifespan to discuss the predicted costs and benefits of physical activity at each stage of life in order to differentiate the obstacles to physical activity and exercise that are functionally adaptive—or were in the environments that they evolved—and identifying which factors are more modifiable than others in order to develop interventions and environments that are more conducive to physical activity.

Physical inactivity is a key determinant of health across the lifespan. A lack of activity increases the risk of heart disease, colon and breast cancer, diabetes mellitus, hypertension, osteoporosis, anxiety and depression and others diseases. Emerging literature has suggested that in terms of mortality, the global population health burden of physical inactivity approaches that of cigarette smoking. The prevalence and substantial disease risk associated with physical inactivity has been described as a pandemic. The prevalence, health impact, and evidence of changeability all have resulted in calls for action to increase physical activity across the lifespan. In response to the need to find ways to make physical activity a health priority for youth, the Institute of Medicine's Committee on Physical Activity and Physical Education in the School Environment was formed. Its purpose was to review the current status of physical activity and physical education in the school environment, including before, during, and after school, and examine the influences of physical activity and physical education on the short and long term physical, cognitive and brain, and psychosocial health and development of children and adolescents. Educating the Student Body makes recommendations about approaches for strengthening and improving programs and policies for physical activity and physical education in the school environment. This report lays out a set of guiding principles to guide its work on these tasks. These included: recognizing the benefits of instilling life-long physical activity habits in children; the value of using systems thinking in improving physical activity and physical education in the school environment; the recognition of current disparities in opportunities and the need to achieve equity in physical activity and physical education; the importance of considering all types of school environments; the need to take into consideration the diversity of students as recommendations are developed. This report will be of interest to local and national policymakers, school officials, teachers, and the education community, researchers, professional organizations, and parents interested in physical activity, physical education, and health for school-aged children and adolescents.

The human body is designed for activity. For most of our history, physical activity was required for survival, but technological advances have eliminated much of the need for hard physical labor. As our activity levels have dropped, it has become clear that a physically inactive lifestyle can lead to a host of health problems. Physical Activity and Health, Second Edition, provides a comprehensive treatment of the research on the benefits of a physically active lifestyle in comparison with the harmful consequences of physical inactivity. Written by leading scientists from the United States, Canada, Europe, and Australia, Physical Activity and Health, Second Edition, brings together the results of the most important studies on the relationship between physical activity, sedentarism, and various health outcomes. The second edition has been fully updated based on the latest advances in this rapidly changing field and expanded to include the following new content: • A chapter on the physiology of inactivity and the effects of sedentary behavior even in people who engage in appropriate amounts of physical activity, which is an area of growing interest • More extensive coverage of physical activity, aging, and the brain, including a new chapter on the relationship between physical activity and brain structures and functions • A chapter on the development of national and international physical activity and health guidelines, which will help readers better understand how scientific findings are converted into practical recommendations Physical Activity and Health, Second Edition, offers a detailed yet concise presentation of key concepts as well as a framework to help readers relate results from single studies or collections of studies to the overall paradigm linking physical activity and physical fitness to health. For each of the topics covered, the text provides an overview of the most important research findings, discusses the limitations of the current knowledge base, and identifies directions for future investigation. At the core of the text is a review of our current understanding of how physical activity affects health concerns such as cardiovascular disease, diabetes, cancer, and obesity as well as aging and mental health. The text identifies sedentary living habits and poor fitness as major public health problems and examines the potential of physical activity to prevent disease and enhance quality of life. This complete resource also looks at the evolution of the field of physical activity and health; variations in physical activity levels across age, sex, and ethnic groups; the body’s physiological responses to physical activity; dose-response issues; and the influence of genetics on physical activity, fitness, and health. The book ends with an integration of the issues covered and discusses new opportunities for research. The second edition of Physical Activity and Health continues to offer clear, user-friendly coverage of the most important concepts and research in the field. Numerous special features will aid readers in their comprehension of the material. Chapter outlines and callout boxes help readers key in on important topics and focus their reading, and chapter summaries, definitions of key terms, and study questions provide tools for review and self-testing. Commonly used acronyms and abbreviations are found on the interior covers for handy reference. Where other books have simply promoted physical activity for the individual or a population, Physical Activity and Health, Second Edition, completely integrates current knowledge of the relationship between physical activity and health. With contributions from some of the finest scientists in the field, this comprehensive text offers information unmatched in accuracy and reliability.

The unique contribution made by biological anthropology to human welfare lies in the fundamental understanding it can provide of the dynamic interrelationships between physical and social factors. By understanding these patterns, we can interpret the significance of variation in such measures of human well-being in terms of the incidence of disease and mortality rates. Topics covered in this book include reproductive ecology and fertility, nutritional status in relation to health, and the effects of pollution on individual growth. In later chapters, the concepts of physiological adaptation and Darwinian fitness and their relation to individual physical fitness are explored.

Can health-care costs be reduced by increasing the overall level of physical activity? What part does heredity play in physical fitness? How does exercise affect the immune system? What is the relationship between physical activity and hypertension?
