Download or read book Associations of Total Activity Counts and Physical Activity Intensity Levels with the Metabolic Syndrome written by Dana Lizbeth Wolff and published by . This book was released on 2014 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: To clarify the protective benefits of physical activity (PA), epidemiologists and public health researchers continue to seek improved methods of assessing PA. In particular, accelerometers have gained acceptance with researchers as they provide reliable estimates of PA and can record both the amount and intensity of ambulatory movement. However, there is concern that accelerometer data reduction techniques may not provide quantitatively accurate measurements of time spent in various PA intensity categories. One way to circumvent these inaccuracies is to use the accelerometer-derived total activity counts (TAC), which is a more direct expression of what the monitor records. In order to explore the efficacy of TAC as a measure of PA, this dissertation used data from the 2003 - 2006 National Health and Nutrition Examination Survey to: 1) investigate whether TAC was more strongly associated with cardiometabolic biomarkers than minutes of moderate-to-vigorous PA (MVPA), 2) determine population-referenced TAC percentiles for the U.S. population, and 3) determine which accelerometer-derived measure(s) of PA intensity and volume provided the best fit for assessing the association with the metabolic syndrome. The first study demonstrated that TAC had stronger associations with cardiometabolic biomarkers than time spent in MVPA bouts of ≥ 10 minutes, suggesting TAC is a more robust measure of PA (Part IV). In the second study, age- and gender- specific population-referenced percentiles for TAC, MVPA, and light PA (LPA) were developed (Part V). This is a different approach to accelerometer data reduction that complements the current method of looking at time spent in intensity sub-categories. The third study used structural equation modeling to examine whether TAC, MVPA, or MVPA plus LPA provided the best fit for assessing the relationship with the metabolic syndrome (Part VI). This study also assessed the relative contribution of LPA, MPA, VPA, and TAC to the reduction in the prevalence of the metabolic syndrome. Results indicated a model with TAC provided the best fit for assessing the relationship between PA and the metabolic syndrome. These findings suggest TAC, may be a better measure of PA when examining the reduction in the metabolic syndrome prevalence.

Download or read book Description of Sporadic Physical Activity and the Relationship Between Non Bouted Physical Activity and the Metabolic Syndrome in American Adults written by Jordan Christopher Donald Robson and published by . This book was released on 2014 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Exercise and Diabetes written by Sheri R. Colberg and published by American Diabetes Association. This book was released on 2013-05-30 with total page 554 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical movement has a positive effect on physical fitness, morbidity, and mortality in individuals with diabetes. Although exercise has long been considered a cornerstone of diabetes management, many health care providers fail to prescribe it. In addition, many fitness professionals may be unaware of the complexities of including physical activity in the management of diabetes. Giving patients or clients a full exercise prescription that take other chronic conditions commonly accompanying diabetes into account may be too time-consuming for or beyond the expertise of many health care and fitness professionals. The purpose of this book is to cover the recommended types and quantities of physical activities that can and should be undertaken by all individuals with any type of diabetes, along with precautions related to medication use and diabetes-related health complications. Medications used to control diabetes should augment lifestyle improvements like increased daily physical activity rather than replace them. Up until now, professional books with exercise information and prescriptions were not timely or interactive enough to easily provide busy professionals with access to the latest recommendations for each unique patient. However, simply instructing patients to “exercise more” is frequently not motivating or informative enough to get them regularly or safely active. This book is changing all that with its up-to-date and easy-to-prescribe exercise and physical activity recommendations and relevant case studies. Read and learn to quickly prescribe effective and appropriate exercise to everyone.
Download or read book The Objective Monitoring of Physical Activity Contributions of Accelerometry to Epidemiology Exercise Science and Rehabilitation written by Roy J. 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 Epidemiologic Methods in Physical Activity Studies written by I-Min Lee and published by Oxford University Press. This book was released on 2008-09-29 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical activity clearly is associated with decreased risk of many chronic diseases, as well as with longer life. Utilizing modern epidemiologic methods, studies of physical activity and health have been conducted since the 1940s. However physical inactivity did not gain widespread acknowledgement as a major risk factor for poor health until 1992, when the American Heart Association recognized it as a risk factor for heart disease, on par with risk factors such as smoking. This text includes chapters describing the associations between physical activity and major diseases. With a major emphasis on the methods underpinning studies that can be conducted to elucidate these associations, this book is an important guide for those performing the informative epidemiologic studies needed to reduce the increasing number of people diagnosed with chronic disease due to inactivity.
Download or read book Metabolic Syndrome written by Isabelle Lemieux and published by MDPI. This book was released on 2021-01-28 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metabolic syndrome has been the topic of countless publications. It still remains a subject of debate and some experts have even questioned its clinical relevance. Its diagnosis is nevertheless predictive of an increased risk of type 2 diabetes and cardiovascular disease even in the absence of traditional risk factors. Many years ago, our team made the point that the most prevalent form of metabolic syndrome was linked to abdominal obesity, which can be found even among individuals who are not considered obese by body weight standards. Imaging techniques such as computed tomography and magnetic resonance imaging have revealed the link between regional body fat partitioning and cardiometabolic risk. Visceral obesity is the most dangerous form of obesity, with subcutaneous obesity being associated with lower health risk. We have proposed that excess visceral fat may be a marker of subcutaneous adipose tissue dysfunction not being able to serve as a metabolic sink, causing lipid accumulation at undesired sites, a condition described as ectopic fat deposition. Among the effective approaches to prevent, delay, or manage metabolic syndrome, lifestyle changes are the key elements, with an emphasis on the importance of healthy global dietary patterns, regular physical activity, and adequate sleep quality.

This book was released on 2013-11-13 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Impact of Freedson Bout Vs Non Freedson Bout Physical Activity on Metabolic Syndrome Risk in College Students written by and published by . This book was released on 2019 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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
Download or read book Physical Activity and the Abdominal Viscera written by Roy J. Shephard and published by Routledge. This book was released on 2017-08-07 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical Activity and the Abdominal Viscera is the first book to examine the response of the visceral organs to acute and chronic physical activity, in cases of both health and disease. Bringing together a previously disparate body of research, Professor Roy Shephard sets out the physiology, function during exercise, pathology of disease, and role of physical activity in preventing and managing disease in the visceral organs. Working systematically through the viscera, the book first identifies the response to exercise and pathologies of the liver, gall bladder and biliary tract, then goes on to examine the function of the kidneys and bladder, and finally covers issues including the spleen, sickle cell disease and prostate cancer. Providing a clear and well-structured guide to the relationship between the visceral organs and physical activity, Physical Activity and the Abdominal Viscera is a vital reference text for academics and upper-level students in sports medicine and clinical exercise physiology, and for health professionals in preventive medicine.
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.
