Shephard and published by Springer. This book was released on 2016-08-02 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines the new knowledge that has been gained from the objective monitoring of habitual physical activity by means of pedometers and accelerometers. It reviews current advances in the technology of activity monitoring and details advantages of objective monitors relative to physical activity questionnaires. It points to continuing gaps in knowledge, and explores the potential for further advances in the design of objective monitoring devices. Epidemiologists have studied relationships between questionnaire assessments of habitual physical activity and various medical conditions for some seventy years. In general, they have observed positive associations between regular exercise and good health, but because of inherent limitations in the reliability and accuracy of physical activity questionnaires, optimal exercise recommendations for the prevention and treatment of disease have remained unclear. Inexpensive pedometers and accelerometers now offer the epidemiologist the potential to collect relatively precisely graded and objective information on the volume, intensity and patterns of effort that people are undertaking, to relate this data to past and future health experience, and to establish dose/response relationships between physical activity and the various components of health. Such information is important both in assessing the causal nature of the observed associations and in establishing evidence-based recommendations concerning the minimal levels of daily physical activity needed to maintain good health.

Download or read book Physical Activity Assessment written by Paul Innerd and published by Routledge. This book was released on 2019-07-10 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lifecourse research in physical activity tracks long-term trends in physical activity behaviours and gives an insight into the link between a physically active lifestyle and later-life health outcomes. However, the complexity of physical activity behaviours, and the analytical issues posed by lifecourse research, present researchers with real challenges in accurately assessing the relationship between lifelong physical activity and health. Physical Activity Assessment: A Lifecourse Approach is the first book to approach the assessment of physical activity for health from a lifecourse perspective and provide students and researchers with much-needed guidance on conducting lifecourse studies. The book provides readers with a thorough grounding in physical activity assessment from across the lifecourse perspective and evaluates current methods of measurement, including comparison studies, criterion methods, subjective assessment methods and physical activity monitors. It then goes on to offer guidance on the optimal measurement techniques of physical activity across the lifecourse, suggesting how data should be collected, analysed and quantified in light of modern technology and global connectivity, and what these methods mean for physical activity guidelines and interventions, and public health outcomes. Offering a unique and novel combination of theoretical grounding and quantitative research guidance, this is important reading for any students taking modules in physical activity measurement or physical activity and health, and any researchers conducting lifecourse physical activity studies.

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.
Download or read book Evaluation of Physical Activity Using Wearable Accelerometers written by William F. Fadel and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: There are many existing methods designed to measure physical activity in public health research. Traditionally, researchers use subjective methods like physical activity diaries and surveys to collect such data as they are relatively inexpensive. However, such methods frequently produce biased results due to the self-report nature of the data collection. In more recent years, wearable accelerometers, or actigraphy devices, have become the norm in physical activity research as they offer a noninvasive and objective measure of participants' daily movements. Accelerometers are relatively small devices that record high frequency time series measurements corresponding to the movements of participants. Analyses of the collected data are complicated by the fact that true physical activity is contaminated by a large amount of noise. Walking is often the only form of sustained physical activity in many populations, but other common daily tasks, such as driving a car, can mimic the walking signal. In our case study, we cover some of the basic features of accelerometer-based measurements, considerations we made when designing the Indiana University Walking and Driving Study, and cover some appropriate feature extraction methods to aid in differentiating between different types of physical activity.

Available in PDF, EPUB and Kindle. Book excerpt: nd Welcome to the proceedings of PERVASIVE 2004, the 2 International C- ference on Pervasive Computing and the premier forum for the presentation and appraisal of the most recent and most advanced research results in all - undational and applied areas of pervasive and ubiquitous computing. Consi- ring the half-life period of technologies and knowledge this community is facing, PERVASIVE is one of the most vibrant, dynamic, and evolutionary among the computer-science-related symposia and conferences. The research challenges, e?orts, and contributions in pervasive computing have experienced a breathtaking acceleration over the past couple of years, mostly due to technological progress, growth, and a shift of paradigms in c- puter science in general. As for technological advances, a vast manifold of tiny, embedded, and autonomous computing and communication systems have st- ted to create and populate a pervasive and ubiquitous computing landscape, characterized by paradigms like autonomy, context-awareness, spontaneous - teraction, seamless integration, self-organization, ad hoc networking, invisible services, smart artifacts, and everywhere interfaces. The maturing of wireless networking, miniaturized information-processing possibilities induced by novel microprocessor technologies, low-power storage systems, smart materials, and technologies for motors, controllers, sensors, and actuators envision a future computing scenario in which almost every object in our everyday environment will be equipped with embedded processors, wireless communication facilities, and embedded software to perceive, perform, and control a multitude of tasks and functions.
Download or read book Application of Methods in Physical Activity Measurement written by Stephen Herrmann and published by . This book was released on 2011 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is broadly accepted that physical activity provides substantial health benefits. Despite strong evidence, approximately 60% to 95% of US adults are insufficiently active to obtain these health benefits. This dissertation explored five projects that examined the measurement properties and methodology for a variety of physical activity assessment methods. Project one identified validity evidence for the new MyWellness Key accelerometer in sixteen adults. The MyWellness Key demonstrated acceptable validity evidence when compared to a criterion accelerometer during graded treadmill walking and in free-living settings. This supports the use of the MyWellness Key accelerometer to measure physical activity. Project two evaluated validity (study 1) and test-retest reliability evidence (study 2) of the Global Physical Activity Questionnaire (GPAQ) in a two part study. The GPAQ was compared to direct and indirect criterion measures including object and subjective physical activity instruments. These data provided preliminary validity and reliability evidence for the GPAQ that support its use to assess physical activity. Project three investigated the optimal h.-1 of accelerometer wear time needed to assess daily physical activity. Using a semi-simulation approach, data from 124 participants were used to compare 10-13 h.1 to the criterion 14 h.-1. This study suggested that a minimum accelerometer wear time of 13 h.d1 is needed to provide a valid measure of daily physical activity. Project four evaluated validity and reliability evidence of a novel method (Movement and Activity in Physical Space [MAPS] score) that combines accelerometer and GPS data to assess person-environment interactions. Seventy-five healthy adults wore an accelerometer and GPS receiver for three days to provide MAPS scores. This study provided evidence for use of a MAPS score for future research and clinical use. Project five used accelerometer data from 1,000 participants from the 2005-2006 National Health and Nutrition Examination Study. A semi-simulation approach was used to assess the effect of accelerometer wear time (10-14 h.d1) on physical activity data. These data showed wearing for 12 h.d1 or less may underestimate time spent in various intensities of physical activity.
Download or read book International Differences in Mortality at Older Ages written by National Research Council and published by National Academies Press. This book was released on 2011-02-27 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1950 men and women in the United States had a combined life expectancy of 68.9 years, the 12th highest life expectancy at birth in the world. Today, life expectancy is up to 79.2 years, yet the country is now 28th on the list, behind the United Kingdom, Korea, Canada, and France, among others. The United States does have higher rates of infant mortality and violent deaths than in other developed countries, but these factors do not fully account for the country's relatively poor ranking in life expectancy. International Differences in Mortality at Older Ages: Dimensions and Sources examines patterns in international differences in life expectancy above age 50 and assesses the evidence and arguments that have been advanced to explain the poor position of the United States relative to other countries. The papers in this deeply researched volume identify gaps in measurement, data, theory, and research design and pinpoint areas for future high-priority research in this area. In addition to examining the differences in mortality around the world, the papers in International Differences in Mortality at Older Ages look at health factors and life-style choices commonly believed to contribute to the observed international differences in life expectancy. They also identify strategic opportunities for health-related interventions. This book offers a wide variety of disciplinary and scholarly perspectives to the study of mortality, and it offers in-depth analyses that can serve health professionals, policy makers, statisticians, and researchers.

Download or read book Physical Activity and Behavioral Medicine written by James F. Sallis and published by SAGE Publications. This book was released on 1998-08-13 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: What type, amount, and intensity of physical activity is good for your health? How much exercise is too much? Can avoiding physical activity make you ill or lead to premature death? This crisply written and thought-provoking book examines such issues to give readers the first integrated and consolidated introduction to what is known about the impact of physical activity on health. By selectively highlighting some of the best and most important research in physical activity, the authors synthesize studies and theory from several disciplines. They use a behavioral-epidemiology framework to organize the book and explore such topics as: physical activity and the health of children, adolescents, and the elderly; physical activity and its impact on mental health; the role of physical activity in prevention of particular diseases; health risks of physical activity; and how much physical activity is enough and how to measure it; how to promote physical activity and community-based physical activity interventions. Throughout the book, the authors offer studies of diverse populations, including different ethnic backgrounds and nationalities, and different gender groups, and different socioeconomic levels. Although the health benefits of physical activity are fairly well-known, this book furthers our understanding of how to help people become active enough to enjoy these benefits.
Download or read book Objective Measurement of Physical Activity with a System of Multiple Wireless Accelerometers written by Mary Elizabeth Rosenberger and published by . This book was released on 2010 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Physical activity plays an important role in disease prevention, yet current objective physical activity measurement standards are inadequate for testing relationships to health outcomes. New technology promises more accurate measurement, but needs to be calibrated with physiologic variables. The purpose of this study was to compare new wireless motion sensors to the current measurement standard for estimating energy expenditure during physical activity. Physical activity was monitored using an Actigraph worn on the hip, a system of seven wireless accelerometers (MITes) and the Oxycon Mobile portable metabolic unit. Twenty-four subjects completed twenty steady-state activities during three testing sessions. Data from the Actigraph and the MITes were compared to measured metabolic equivalents (METs) to estimate energy expenditure and classify activity intensity. Several sensors improve classification of the intensity of physical activity and sedentary behaviors compared to one sensor worn on the hip. Additionally, the Actigraph was calibrated for measuring sedentary behavior, where previous work relied on casual observation data. Use of new technology will improve physical activity measurement and therefore provide a tool for clarifying the relationship between activity and various health outcomes. Furthermore, both the Actigraph and MITes can be used to measure sedentary behavior, and therefore provide insight into the unique relationship between health and inactivity independent of physical activity.
