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.

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 Assessment of Physical Activity and Sedentary Behavior Using Wearable Sensors written by Amanda Hickey and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The aims of study one of this dissertation were two-fold: 1) To understand the variability of sedentary behavior (SB) throughout a seven-day measurement period and 2) To determine the number of days of SB measurement required to reliably estimate seven-days of measurement. To address these aims, we utilized activPAL (AP) data from two existing data sets from the Physical Activity (PA) and Health Laboratory. Data were from 62 adults and 34 adolescents who had seven consecutive days of valid monitor wear. We found that adults were more sedentary on weekdays compared to weekend days, but there were no differences by type of day in adolescents. Results also suggest that two days of wear in adults and three days of wear in adolescents provide estimates comparable to a seven-day day measurement period. Our observation that less than seven-days of data are needed to reliably estimate SB is a novel finding and will reduce measurement burden for researchers and participants in future studies. For study two, we sought to determine the feasibility of assessing SB/PA with wearable sensors in a clinical population. More specifically, the aims of this part of the dissertation were 1) To quantify changes in objectively measured PA and SB using an AP during the natural progression of osteoarthritis (OA) over a nine-month period and 2) To determine the relationship between change in objectively measured PA and SB and patient reported pain and function. Participants were monitored immediately following a baseline clinic visit and after three, six, and nine-month follow-up visits. In addition, we correlated these PA/SB metrics with patient-reported changes in pain and function. We found no changes in any SB metrics (% of time spent sedentary, breaks per day, and break-rate) at three, six, and nine months in comparison to baseline. There were, however, significant declines in activity metrics (% of time spent stepping, guideline minutes, guideline bouts, % of time spent in moderate-to-vigorous PA and steps per day) at each subsequent time-point. The percent change for declines in activity metrics ranged from 0.1% to 42%. The R2 values describing the relationship between the SB/PA variables and the patient reported pain and function using the WOMAC were all low (range: 0 to 0.14). The results from this part of the dissertation demonstrate that it is a feasible approach to longitudinally quantify natural changes in PA/SB as OA progresses and they also provide insight into how activity behavior changes over time and informs the literature that interventions to help individuals maintain their PA levels are warranted. The aims of study three were: 1) To determine if the ActiGraph (AG) and AP provide comparable estimates of PA and SB in a sample of patients with OA and 2) To compare the relationships between patient-reported pain and function and PA/SB measures from the AP and AG accelerometers. Two SB cutpoints from the AG were utilized (100 counts∙min-1 (AG100) and 150 counts∙min-1 (AG150)). There were significant differences between the AP and AG150 for measures of % of time spent sedentary (difference of 6.3%), breaks per day (difference of 30 breaks), and steps per day (difference of 879 steps). There were significant differences between the AP and AG100 for breaks per day (difference of 30 breaks) and steps per day (difference 640 steps). Average guidelines minutes and number of guidelines bouts were comparable among the AP, AG100 and AG150. The association between the SB and PA variables and the patient reported pain and function were very weak (all R2 values

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.

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.
Download or read book Assessment of Physical Function from Patterns in Routine Physical Activity Measured by Wearable Activity Monitors written by Vibhu Agarwal and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Limitations in physical functioning can lead to dire health and financial consequences. However, the progression of physical function impairment interacts with many different factors, such as organ function, activities and the environment. It is suspected that the complexity of physical function evaluation methods contributes to the low prevalence of function assessments in routine care. Earlier studies have shown that a bidirectional and monotonic relationship exists between physical activity and function. Wearable activity monitors (WAM) -- devices equipped with one or more accelerometers, offer an opportunity to infer physical function from the observed physical activity objectively and at scale. However, efforts to infer function from such activity measurements have been limited. In this dissertation I present methods to infer physical function from daily activity data. Using free-living activity data from the physical activity studies in the Osteoarthritis Initiative, I show that activity measurements obtained by a WAM are sensitive to changes in physical function, if we use an appropriate representation for daily activity. Further, I show that a representation of physical activity that quantifies a subject's engagement in different classes of activity patterns, improves the performance in a physical function classification task. I also demonstrate how such an activity representation may be constructed in an unsupervised manner, obviating the need for time consuming annotation of activity data. Finally, I motivate the case for a composite score of physical function and present two methods for deriving such a score from free-living activity. I also present evaluations of the computed score on predicting key events in the natural history of knee osteoarthritis. Inferring physical function from wearable activity monitors will enable remote monitoring of function, which in turn will facilitate better delivery of care to patients, at a lower cost.

This book was released on 2019-01-21 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Regular physical activity is proven to help prevent and treat noncommunicable diseases (NCDs) such as heart disease stroke diabetes and breast and colon cancer. It also helps to prevent hypertension overweight and obesity and can improve mental health quality of life and well-being. In addition to the multiple health benefits of physical activity societies that are more active can generate additional returns on investment including a reduced use of fossil fuels cleaner air and less congested safer roads. These outcomes are interconnected with achieving the shared goals political priorities and ambition of the Sustainable Development Agenda 2030. The new WHO global action plan to promote physical activity responds to the requests by countries for updated guidance and a framework of effective and feasible policy actions to increase physical activity at all levels. It also responds to requests for global leadership and stronger regional and national coordination and the need for a whole-of-society response to achieve a paradigm shift in both supporting and valuing all people being regularly active according to ability and across the life course. The action plan was developed through a worldwide consultation process involving governments and key stakeholders across multiple sectors including health sports transport urban design civil society academia and the private sector.
