Book Description
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.

Book Description
Current options for maintaining or slowing aging-related bone mineral density (BMD) loss in postmenopausal women primarily include pharmaceutical agents. More recently, physical activity and exercise have been suggested as highly effective, low cost alternatives. Weighted aerobic exercise, utilizing load carriage systems (LCS), is known to increase the gravitational forces impacting bone, creating a higher osteogenic stimulus than standard aerobic exercise. In response to the positive research on aerobic exercise with well-designed LCS, Dr. Lawrence Petrakis, MD, developed a unique 5.44 kg uniformly weighted exercise suit. This study aimed to examine the effects of the uniformly weighted exercise suit on serum biochemical markers of bone formation (Amino- Propeptide of Type 1 Collagen [P1NP]; Carboxy-Terminal Propeptide of Type 1 Collagen [P1CP] and resorption (Carboxy-Terminal Telopeptide of Type 1 Collagen [CTX]) in response to submaximal aerobic exercise in postmenopausal women with low bone density. Nine volunteer, sedentary to lightly active, healthy postmenopausal women (Age: 58.7±1.1 years, BMI: 28.2±1.0, BMD T-score: -1.2±0.5) participated in this within-subjects study, wherein each participant exercised under two counterbalanced conditions (aerobic exercise with [ES] or without [NS] the exercise suit). During each condition, participants walked on a treadmill at 65%-75% of their age-predicted maximum heart rate until they reached their goal caloric expenditure (400kcal). There was a seven-day washout period between sessions. Serum was processed using ELISA protocols to investigate the change in biomarker at 24 and 72 hours post exercise, relative to baseline. The results indicated, when compared to the NS condition, the ES condition elicited a greater positive change in P1CP at 24 hours (Phours following exercise (P0.05). There was no effect of condition on P1NP at any time point (P>0.05). In sum, submaximal aerobic exercise while wearing the uniformly weighted exercise suit elicited an antiresorptive effect on bone collagen resorption with a simultaneous increase in bone collagen formation 24 hours post exercise.

"Introduction: Osteopenia/Osteoporosis increases the patient's risk of fracture. Fractures can have a physical, psychological and social consequence that affects Health Related Quality of Life (HRQoL.) The purpose of this systematic review was to investigate the effectiveness of physical therapy interventions on Bone Mineral Density (BMD) and HRQoL in postmenopausal women diagnosed with osteopenia and/or osteoporosis. Methods: The following databases were searched:Medline, CINHAL, PubMed, Ebsco Host, NCBI, Google Scholar and Sports Discuss between November 2009 to June 2010. Research articles were chosen that focused on HRQoL and Bone Mineral Density (BMD)in postmenopausal women with osteopenia/osteoporosis. Results: After reviews of each article, 16 studies met the inclusion criteria. The evidence suggests that exercise intervention (strengthening, balance training, fall prevention, aerobic, and aquatic exercise)can have positive effects on postmenopausal women with osteopenia/osteoporosis. Discussion: Exercise intervention should be a component of standard care for women diagnosed with osteopenia/osteoporosis. Clinical Implications: Clinical application of the findings of this systematic review can be used on a wide variety of patients. A patient with osteopenia/osteoporosis will benefit from exercise intervention and this can be performed without any extra cost." -- Abstract.

Book Description
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.
