This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Female Athlete Triad (Triad), a syndrome of low energy availability, menstrual dysfunction, and low bone mineral density (BMD), affects up to 60% of exercising girls and women. As such, understanding the physiology underlying the Triad is imperative in order to identify therapeutic targets and develop effective treatment strategies to prevent long-term health detriments in afflicted women. Bone health is a major clinical outcome of concern in female athletes and exercising women with the Triad, as bone loss or suboptimal peak bone mass development may predispose women to osteoporosis and related fractures later in life. To garner a better understanding of factors contributing to bone health and to inform guidelines for treatment targets in female athletes and exercising women with the Triad, this purpose of this dissertation was 1) to assess the unique and combined effects of energy status and estrogen status on volumetric BMD (vBMD), bone geometry, and estimated bone strength in exercising women, 2) to assess the unique and combined effects of energy status and estrogen status on bone turnover in exercising women, 3) to evaluate predictors of change in bone turnover dynamics across a 12-month nutritional intervention in women with exercise-associated menstrual disturbances, and 4) to determine if bone turnover dynamics at baseline impact BMD outcomes in women with exercise-associated menstrual disturbances participating in a nutritional intervention. Key findings of the studies that made up this dissertation implicate that energy status is a main driving factor dictating vBMD, bone geometry, estimated bone strength, and bone metabolism in exercising women. The results indicate that improving energetic status will not only improve bone turnover at the cellular level, but that bone turnover favoring bone formation over bone resorption will also predict improved BMD in the following year. The findings support the guidelines put forth by the Female Athlete Triad Coalition that endorse nutritional therapy as the first line of treatment for the Triad, as low energy availability is the root cause of the clinical sequelae, including menstrual dysfunction and compromised bone health.

Available in PDF, EPUB and Kindle. Book excerpt: This first-ever Surgeon General's Report on bone health and osteoporosis illustrates the large burden that bone disease places on our Nation and its citizens. Like other chronic diseases that disproportionately affect the elderly, the prevalence of bone disease and fractures is projected to increase markedly as the population ages. If these predictions come true, bone disease and fractures will have a tremendous negative impact on the future well-being of Americans. But as this report makes clear, they need not come true: by working together we can change the picture of aging in America. Osteoporosis, fractures, and other chronic diseases no longer should be thought of as an inevitable part of growing old. By focusing on prevention and lifestyle changes, including physical activity and nutrition, as well as early diagnosis and appropriate treatment, Americans can avoid much of the damaging impact of bone disease and other chronic diseases. This Surgeon General's Report brings together for the first time the scientific evidence related to the prevention, assessment, diagnosis, and treatment of bone disease. More importantly, it provides a framework for moving forward. The report will be another effective tool in educating Americans about how they can promote bone health throughout their lives. This first-ever Surgeon General's Report on bone health and osteoporosis provides much needed information on bone health, an often overlooked aspect of physical health. This report follows in the tradition of previous Surgeon Generals' reports by identifying the relevant scientific data, rigorously evaluating and summarizing the evidence, and determining conclusions.

Book excerpt: There are a number of therapies and treatments available for the prevention of fragility fractures in people thought to be at risk, or to prevent further fractures in those who have already had one or more fragility fractures. However, identifying who will benefit from preventative treatment is imprecise. A number of risk assessment tools are available to predict fracture incidence over a period of time, and these may be used to aid decision making. These tools are limited in that they may not include all risk factors, or may lack details of some risk factors. Tools are dependent on the accuracy of the epidemiological data used to derive them and tools validated in other populations may not apply to the UK. Two tools, FRAX and QFracture, are available for use in the UK. It is not clear whether these tools are equally accurate and whether choice of tool should depend on circumstances. This short clinical guideline aims to provide guidance on the selection and use of risk assessment tools in the care of people who may be at risk of fragility fractures in all settings in which NHS care is received.

This book was released on 2007-01-01 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: Osteoporosis and related fractures are a major public health problem globally. Although traditionally considered to be a disease affecting the elderly, increased recognition that osteoporosis may have its foundation early in life has stimulated substantial research interest into factors which can influence skeletal development, including both genetic and lifestyle factors. This book provides a summary and integrative review of the current state of knowledge of factors that influence the development of bone health during childhood and adolescence. The focus is on the role of physical activity for optimizing bone development. Other relevant topics that are reviewed include the influence of genetics, nutrition, and hormonal factors on skeletal development. In addition, there are expert views on practical lifestyle strategies and guidelines that can be adopted to optimize bone health and prevent fractures during growth. The book provides an excellent source of recent information for exercise specialists, pediatricians, nutritionists, biomedical researchers, health promotion worker and public health professionals.

Available in PDF, EPUB and Kindle. Book excerpt: This is the first book of its kind to focus solely on the female athlete triad - its origins, its recognition, and most importantly, its management. Since the symptoms themselves cover a range of medical specialties, chapters are written by experts in a number of relevant fields - sports medicine, orthopedics, endocrinology, and pediatrics - with an eye toward overall care of the young female athlete. Additionally, each chapter includes suggestions on how to educate and communicate with young athletes and their parents, as well as trainers and coaches, on how to manage the illness outside of the direct clinical setting. The female athlete triad is often seen in sports where low body weight is emphasized, such as gymnastics, figure skating, and running, though it can appear in any sport or activity. The interrelated symptoms - eating disorders, amenorrhea, and low bone mass - exist on a spectrum of severity and are serious and potentially life-threatening if not properly treated. Psychological problems, in addition to medical ones, are not uncommon. The Female Athlete Triad: A Clinical Guide discusses all of these areas for a well-rounded and in-depth approach to the phenomenon and will be a useful reference for any clinician working with female athletes across the lifespan.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Exposures during childhood that affect bone mineral density (BMD) and bone mineral content (BMC) could have long-term effects on osteoporosis development and associated fracture risk. We evaluated associations of physical activity in late childhood, adolescence, and in young adulthood with young adult BMD and BMC using data from the Dietary Intervention Study in Children (DISC) and DISC06 Follow-up Study. Moderate/Intense physical activity (MET hours/week) was assessed by questionnaire on five occasions during childhood/adolescence and again during young adulthood. BMD and BMC were measured by dual energy x-ray absorptiometry (DEXA) scans during young adulthood. Linear mixed models were used to analyze the association of physical activity with BMD and BMC during young adulthood. Generalized linear latent affects mixed models were used to evaluate the association of the latent variable "childhood physical activity" with BMD and BMC in young adulthood. Young adult BMC and BMD increased with increasing physical activity during young adulthood after adjustment for body weight, although the test for trend was significant only for BMD. Young adult BMC increased significantly with increasing physical activity during youth. Promotion of physical activity in youth and young adulthood could potentially decrease the magnitude of osteoporosis in older women as a public health problem, but more research is needed.

Download or read book A Comparison of Physical Activity (high and Low) and Bone Mineral Density in Young, Healthy Eumenorrheic Females written by Patricia C. Fehling and published by . This book was released on 1992 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: The comparison of chronically high (n = 37) and low (n = 37) levels of physical activity and bone mineral density (BMD) was investigated in young (12-22 years), healthy, eumenorrheic females. Subjects were placed into physical activity groups based on current and past physical activity patterns. Subjects in the high physical activity group currently engaged in an average of 10 hours per week of physical activity, while subjects in the low physical activity group exercised an average of 55 minutes per week. It was hypothesized that, regardless of measurement site, the high physical activity group would have a greater BMD when compared to the low physical activity group. Bone mineral density was obtained in the total body, lumbar spine (L1-L4), and proximal femur by dual-energy radiography, and the mid-shaft site of the bilateral radii by single photon absorptiometry. Additional measures of physique, body composition, nutritional intake, and caloric expenditure were obtained. The high physical activity group had significantly greater BMD than the low physical activity group at all measurement sites. After adjusting for weight, the significance between the physical activity groups remained in the lumbar spine, proximal femur, and femoral neck BMD. Additionally, adjustments for height resulted in a significant difference remaining in lumbar BMD. Weight, height, lean body mass, and several circumferences and skeletal widths correlated with lumbar spine, proximal femur, and total body bone mineral. The relationship between age and bone mineral measurements was linear at all of the measurement sites. There was no significant difference in the amount of calcium consumed between the physical activity groups. The results indicate that high levels of physical activity in young healthy females are associated with a greater BMD at several clinically important measurement sites, when compared to less active females, even after adjustments for size are made.

Download or read book The Effects of Exercise on Bone Mineral Density in Postmenopausal Women written by Dana M. Smith and published by . This book was released on 1999 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: A meta-analysis was done to determine what effect exercise has on the bone mineral density (BMD) of the lumbar spine, proximal femur, and distal radius in postmenopausal women, utilizing data from 18 studies. Treatment effects (TE) were calculated for each of the skeletal sites, aerobic and strength training, as well as methods of BMD measurement (dual energy x-ray absorptiometry and dual photon absorptiometry). The resulting TEs found exercise, in general, to significantly increase (p c 0.05) the BMD of the lumbar spine (0.73%), and the proximal femur (0.35%); however, the distal radius showed a decrease ( -0.91%) in BMD. When looking for the effect of aerobic versus strength training, significant (p c 0.05) increases in BMD were found in the spine and femur. Since positive changes were not seen in all sites, the benefits of exercise may be specific to the skeletal sites which the working muscles are attached. When the % change for exercise and control groups were analyzed separately, the exercise group increased 2.31% at the lumbar spine and 0.61% at the proximal femur. However, the exercise group decreased -2.21% at the radius. The control group decreased at the lumbar spine -1.09%, and at the femur -1.1 I%, however, increased at the radius 0.36%. The BMD % changes were significantly larger for the spine and femur, therefore, vigorous exercise along with resistance training may help slow the decrease in BMD as one ages.
