Full Description
"Physical Activity and Health" explains clearly, systematically and in detail the relationships between physical activity, health and disease, and examines the benefits of exercise in the prevention and treatment of a wide range of important health conditions. The book critically considers the evidence linking levels of physical activity with disease and mortality. It explores the causes of specific health conditions and syndromes prevalent in developed societies, such as cardiovascular disease, Type 2 diabtetes, obesity and cancer, and discusses the role of physical activity in their prevention or alleviation. Throughout, the book draws on cutting edge research literature and is designed help the student to evaluate the quality and significance of the scientific evidence.A concluding section explores broader themes in exercise and public health, including therapeutic uses of exercise; exercise and aging; children's health and exercise, and physical activity and public health policy, and includes a critical appraisal of current recommendations for physical activity.Containing useful pedagogical features throughout, including chapter summaries, study activities, self evaluation tasks, guides to 'landmark' supplementary reading and definitions of key terms, and richly illustrated with supporting case-studies, tables, figures and plates, "Physical Activity and Health" is an essential course companion. It is vital reading for degree-level students of sport and exercise science, public health, physical therapy, medicine, nursing and nutrition.
