Book Description
Less than 15% of North American adults currently met the physical activity guidelines. These guidelines recommend that adults accumulate at least 150 minutes per week of moderate-to-vigorous physical activity (MVPA) in bouts of 10 minutes or more. Emerging evidence suggests that accumulating sporadic MVPA (i.e. physical activity performed in periods of less than 10 consecutive minutes) also has health benefits. Little is known about how much sporadic physical activity (SPA) adults get. Furthermore, it is not known if SPA needs to be of at least moderate intensity to convey health benefits. The purpose of this thesis was twofold: 1) to describe SPA levels and intensity patterns in adults, and 2) to investigate the relationship between various intensities of SPA and the metabolic syndrome. The metabolic syndrome is a clustering of risk factors for cardiovascular disease and diabetes. Data for the thesis research came from the National Health and Nutrition Examination Survey, a representative cross-sectional sample of adults from the United States. Physical activity was measured over 7 days using accelerometers, which are small electronic sensors worn on the hip. The metabolic syndrome was determined from direct body measurements and blood samples. Results of this thesis indicate that the typical American adult accumulates 103 minutes/day of SPA, which represented 27% of their total daily physical activity. Of these 103 minutes/day, only 2 minutes/day were of moderate-to-vigorous intensity. However, adults accumulated 16 minutes/day of MVPA that was embedded within bouts of primarily light intensity activity - is activity did not meet the MVPA bout criteria but it was not truly sporadic since it occurred within bouts of primarily light intensity activity. Accumulation of this iii embedded MVPA was as strongly related to the MetS as bouted MVPA. Conversely, sporadic light intensity physical activity was weakly associated with the metabolic syndrome. Together, these results suggest MVPA is commonly accumulated outside of the current recommended bout length and that this type of activity is strongly associated with the metabolic syndrome.

Book Description
The statistics are disturbing: steadily rising numbers of sedentary overweight children and obese teens, and a generation looking at a shorter life expectancy than their parents’. But while it may be obvious that physical fitness benefits both the mind and body, a growing research base is supplying evidence of why this is so, and how these benefits may be reproduced in greater numbers. Physical Activity Across the Lifespan makes a clear, scientific case for exercise, sports, and an active lifestyle in preventing illness and establishing lifetime health habits at both the individual and the population levels. The book focuses on key aspects of physical/mental well-being—weight, mood, and self-regulation—and the role of physical activity in public health and school-based interventions targeting these areas. Contributors review definitional and measurement issues salient to understanding what physical activity is, to analyzing benefits of participation, and to implementing effective interventions. Also addressed are limitations of current research, steps needed to continue building the field, and emerging therapeutic possibilities for activity, such as the role of rough and tumble play in preventing ADHD. Included in the coverage: Physical activity, cognition, and school performance. The influence of social and built environments on physical activity in middle-aged and older adults. Preventing and treating obesity through physical activity. Physical activity in preventing drug use and treating chemical dependence. Antidepressant properties of physical activity. Schools as a foundation for physical activity and an active lifestyle. Physical activity as an adjunct or booster to existing interventions. Physical Activity Across the Lifespan is an innovative text for researchers and practitioners in various disciplines including health promotion/disease prevention, child and school psychology, education, health psychology, and public health, as well as program developers and policymakers in these areas.

Book Description
Physical Activity Epidemiology, Second Edition, provides a comprehensive discussion of current population-level studies showing the influence of physical activity on disease. Updated with extensive new research collected in the eight years since the previous edition, the second edition adds the expertise of respected epidemiologist I-Min Lee. To assist readers in understanding the public health significance of physical activity, Dishman, Heath, and Lee present a detailed review of research findings and what those findings suggest regarding the relationship between physical activity and a variety of health risks. The second edition of this groundbreaking text has been exhaustively updated to reflect the wealth of new research published in this fast-moving field of study. With more than 100 pages of additional content, the text also offers more detailed coverage of all-cause and coronary heart disease mortality, expanded coverage of pathophysiology and biological plausibility, new information on physical activity among various racial–ethnic populations, and the effects of physical activity on cognitive function, dementia, and HIV/AIDS. More than 250 tables and figures, twice the number found in the previous edition, highlight the latest epidemiological information in an easy-to-understand visual format. Physical Activity Epidemiology, Second Edition, assists readers in understanding how leisure-time physical activity can enhance people’s quantity and quality of life by summarizing the available knowledge, detailing the methods used to obtain it, considering its implications for public health, and outlining the important questions that remain. Readers will find comprehensive discussion of these topics: • Evidence that physical activity protects against the development of coronary heart disease and stroke and premature death from all causes • Population-based studies and clinical experiments providing evidence that physical activity and exercise play a role in the primary and secondary prevention of mild hypertension, dyslipidemia, and obesity • Contemporary epidemiologic evidence that physical activity reduces the risk of type 2 diabetes and osteoporosis and protects against the development of breast and colon cancers, some inflammatory diseases, depression, and anxiety disorders • Considerations in the promotion of a safe, physically active lifestyle among all segments of the population Physical Activity Epidemiology, Second Edition, will engage and challenge students by examining the state of current research in all of its variation and even ambiguity. The text details the methodology and findings of classic and contemporary studies and then helps students begin to analyze the results. Special Strength of the Evidence sections found at the end of most chapters summarize the findings to determine the extent to which correlation and causation can be proven. Chapter objectives, chapter summaries, and sidebars in each chapter assist students in focusing on the key points of study, and an extensive glossary with detailed definitions provides a handy reference for review. Instructors will find a new image bank in this edition to enhance their class lecture materials. Physical Activity Epidemiology, Second Edition, offers students, sport and exercise scientists, health and fitness professionals, and public health administrators a comprehensive presentation of significant studies, how these studies contribute to understanding the relationship between activity and disease prevention, and how this information can be used in leading individuals, communities, and global society toward increased health and longevity.

Book Description
Purpose The aim of this study is to examine moderate to vigorous physical activity in Freedson bouts compared to non-Freedson bouts and their association with Metabolic Syndrome risk factors in college students. Methods 72 subjects aged 18-26 were recruited from James Madison University. Subjects height, weight, waist circumference, blood pressure, and body composition were assessed on visit 1. Blood pressure, fasted blood glucose, and lipid profile were assessed on visit 2. Subjects wore an Actigraph GT3X+ accelerometer, which measured physical activity and sleep for 7 days and nights. Univariate Pearson correlation analyses were performed to determine the relationship physical activity variables and MetS risk factors. Variables determined to have the greatest correlation for each risk factor were used as independent variables in a step-wise, multiple linear regression to determine the best predictor for each MetS risk factor. Variables established as having the greatest correlation with MetS were evaluated as covariates. Statistical significance was set a priori at p0.05. Results Correlational analyses suggest the strongest predictors of MetS were daily average time in moderate activity, daily average MVPA, total number of Freedson bouts, total minutes in Freedson bouts, total MVPA, and total steps. Step count was the only significant predictor of waist circumference and systolic blood pressure (Rsup2/sup= 0.07; p0.05; Rsup2/sup= 0.14; p

Book Description
Is there a sufficient evidence base for the U.S. Department of Health and Human Services (HHS) to develop a comprehensive set of physical activity guidelines for Americans? To address this question, the Institute of Medicine (IOM) held a workshop titled "Adequacy of Evidence for Physical Activity Guidelines Development" in Washington, DC on October 23-24, 2006, sponsored by HHS. The workshop summary includes the presentations and discussions of more than 30 experts who were asked to consider the available evidence related to physical activity and the general population, as well as special population subgroups including children and adolescents, pregnant and postpartum women, older adults, and persons with disabilities. The summary provides an overview of the specific issues of relevance in assessing the quality and breadth of the available evidence.

Book Description
This book addresses the origins, determinants and magnitude of the global problem of sedentary behaviour, along with concise yet in-depth solutions for tackling it. As a consequence of major technological advances in modern society, many people find themselves in environments characterized by prolonged sedentary behaviour. Although inadequate exercise has long been known to cause adverse health consequences, sedentary behaviour has recently emerged as a risk factor for the development of numerous chronic diseases and health conditions. Building on the contributions of leading experts in the field, this book presents current knowledge about sedentary behaviour, its medical and public health significance, its correlates and determinants, measurement techniques, and recommendations for addressing this behaviour at the individual, community, environmental, and policy level. Applying a cross-disciplinary methodology, the book avoids considering physical activity and sedentary behavior as a single continuum, which potentially hampers progress in confronting widespread levels of sedentariness. Rather, the book helps readers better understand how sedentary and physically active behavior co-occur and how the two behaviours have distinct contributing factors. Building on the contributions of distinguished international experts in the field, this thorough resource is a valuable asset and challenges professionals, researchers, students, and practitioners alike to adopt new strategies and expand their reach.
