Abstract

Aim. To explore the effects of long-term Shadowboxing exercise in prevention of osteoporosis in the aged. Methods. Sixty old people, 20 males and 40 females with an average age of (67.0 ± 1.3) years, were divided into two groups: control group without conscious exercise (n = 32), and exercise group with Shadowboxing exercise(n = 28). The bone mineral density (BMD) of lumber spine(L2-4) and proximal femur(neck of femur, torch, wards triangle) of 60 old people was measured by double energy X-ray absorption (DEXA) made in American Norland Corporation. Results. The BMD of lumber spine and proximal femur in the Shadowboxing exercise group were significantly higher than those of the controls (t = -6.63 to -2.23, P < 0.05). The BMD was insignificantly correlated with the exercise year over 5 years (t = 0.08 ∼ 1.60, P > 0.05). Conclusion. Shadowboxing exercise increases the BMD of the aged people effectively. With time passed, the prevention of shadowboxing exercise against osteoporosis is limited.

Osteoporosis is a disease characterized by fragile bones and high susceptibility to low trauma fractures. Tai Chi, an ancient Chinese mind-body exercise that is reported to enhance muscle function, balance and flexibility, and to reduce pain, depression and anxiety, may safe-ly and effectively be used to prevent or treat osteoporosis. The aim of this review is to eval-uate the evidence for Tai Chi as an interven-tion to reduce rate of bone loss in post-menopausal women. A literature search on randomized controlled trials (RCTs), prospec-tive cohort studies, and cross-sectional studies that included Tai Chi as an intervention, and had at least 1 outcome related to measurement of bone metabolism were identified in PubMed/Medline. Twenty-one controlled stud-ies were identified in the database, which sug-gested Tai Chi slowed down the loss of bone mineral density in most postmenopausal women, improved balance and strength, relieves pain from arthritis, and improved mental strength so they can cope better with chronic diseases. Regular Tai Chi Chuan exer-cise is beneficial for retarding bone loss in the weight-bearing bones of postmenopausal women.
... Prior research on the effects of TC on BMD in postmenopausal osteopenic women is limited [14,15]. Crosssectional studies including elderly women suggest longterm TC practitioners have higher BMD than agematched sedentary controls [37,38], and have slower rates of post-menopausal BMD decline [11]. One RCT in post-menopausal women observed that DXA measures of BMD at the lumbar spine significantly increased (1.81%) following 10 months of TC while sedentary controls decreased (1.83%) [39]. ...

Tai Chi (TC) is a mind-body exercise that shows potential as an effective and safe intervention for preventing fall-related fractures in the elderly. Few randomized trials have simultaneously evaluated TC's potential to reduce bone loss and improve fall-predictive balance parameters in osteopenic women. In a pragmatic randomized trial, 86 post-menopausal osteopenic women, aged 45-70, were recruited from community clinics. Women were assigned to either nine months of TC training plus usual care (UC) vs. UC alone. Primary outcomes were changes between baseline and nine months of bone mineral density (BMD) of the proximal femur and lumbar spine (dual-energy X-ray absorptiometry) and serum markers of bone resorption and formation. Secondary outcomes included quality of life. In a subsample (n = 16), quiet standing fall-predictive sway parameters and clinical balance tests were also assessed. Both intent-to-treat and per-protocol analyses were employed. For BMD, no intent-to-treat analyses were statistically significant; however, per protocol analyses (i.e., only including TC participants who completed ≥ 75% training requirements) of femoral neck BMD changes were significantly different between TC and UC (+0.04 vs. -0.98%; P = 0.05). Changes in bone formation markers and physical domains of quality of life were also more favorable in per protocol TC vs. UC (P = 0.05). Changes in sway parameters were significantly improved by TC vs. UC (average sway velocity, P = 0.027; anterior-posterior sway range, P = 0.014). Clinical measures of balance and function showed non-significant trends in favor of TC. TC training offered through existing community-based programs is a safe, feasible, and promising intervention for reducing multiple fracture risks. Our results affirm the value of a more definitive, longer-term trial of TC for osteopenic women, adequately powered to detect clinically relevant effects of TC on attenuation of BMD loss and reduction of fall risk in this population.

This article compares and contrasts two systematic reviews of t'ai chi (TC) interventions on bone mineral density in postmenopausal women. The aim is to examine how chosen quality rating instruments can impact systematic reviews of TC literature. The rating instruments in the reviews, the three-item scale of Jadad et al. and the ad hoc checklist of Wayne et al., were analyzed using Oxman's evaluation criteria for systematic reviews regarding inclusion of articles, interpretation of results, and overall implications for the efficacy of TC on bone mineral density. According to Oxman's criteria, the Jadad scale did not address advances in statistical methods and was not comprehensive enough to adapt to the clinical context or topic. In contrast, the checklist by Wayne et al. was comprehensive, adaptable to clinical context and topical relevance, and compatible with recent developments in statistics and experimental design. These quality rating instruments were critical in the inclusion of studies, analyses, and overall conclusions summarizing the TC literature. The conclusions from the two systematic reviews were starkly opposing; Lee et al. found no convincing evidence, dismissing TC studies as low quality, while Wayne et al. stated that TC may be an effective, safe, and practical intervention. Readers must exercise caution concerning high or low ratings from systematic reviews of TC studies because the choice of quality rating tool can dramatically influence the summary and conclusions of the reviews. There is no consensus on quality rating standards at this time. Of the two, the Jadad scale was not only inadequate but also inappropriate for reviewing TC studies, potentially misleading researchers, clinicians and policymakers. Future systematic reviews of TC should utilize instruments that are updated to current scientific standards, comprehensive, adaptable to clinical context, and relevant to the research topic.
... Research on the direct effects of Tai Chi on BMD is more limited and less conclusive [7,45]. Ten relevant studies are available in the literature, which suggest the following: (1) Long-term Tai Chi practitioners have higher BMD464748 than age-matched sedentary controls , and have slower rates of post-menopausal BMD decline [47]. (2) Tai Chi-naïve women who undergo Tai Chi training exhibit reduced rates of post-menopausal BMD decline. ...

Post-menopausal osteopenic women are at increased risk for skeletal fractures. Current osteopenia treatment guidelines include exercise, however, optimal exercise regimens for attenuating bone mineral density (BMD) loss, or for addressing other fracture-related risk factors (e.g. poor balance, decreased muscle strength) are not well-defined. Tai Chi is an increasingly popular weight bearing mind-body exercise that has been reported to positively impact BMD dynamics and improve postural control, however, current evidence is inconclusive. This study will determine the effectiveness of Tai Chi in reducing rates of bone turnover in post-menopausal osteopenic women, compared with standard care, and will preliminarily explore biomechanical processes that might inform how Tai Chi impacts BMD and associated fracture risks. A total of 86 post-menopausal women, aged 45-70y, T-score of the hip and/or spine -1.0 and -2.5, have been recruited from primary care clinics of a large healthcare system based in Boston. They have been randomized to a group-based 9-month Tai Chi program plus standard care or to standard care only. A unique aspect of this trial is its pragmatic design, which allows participants randomized to Tai Chi to choose from a pre-screened list of community-based Tai Chi programs. Interviewers masked to participants' treatment group assess outcomes at baseline and 3 and 9 months after randomization. Primary outcomes are serum markers of bone resorption (C-terminal cross linking telopeptide of type I collagen), bone formation (osteocalcin), and BMD of the lumbar spine and proximal femur (dual-energy X-ray absorptiometry). Secondary outcomes include health-related quality-of-life, exercise behavior, and psychological well-being. In addition, kinetic and kinematic characterization of gait, standing, and rising from a chair are assessed in subset of participants (n = 16) to explore the feasibility of modeling skeletal mechanical loads and postural control as mediators of fracture risk. Results of this study will provide preliminary evidence regarding the value of Tai Chi as an intervention for decreasing fracture risk in osteopenic women. They will also inform the feasibility, value and potential limitations related to the use of pragmatic designs for the study of Tai Chi and related mind-body exercise. If the results are positive, this will help focus future, more in-depth, research on the most promising potential mechanisms of action identified by this study. This trial is registered in Clinical Trials.gov, with the ID number of NCT01039012.

Background: This study compared the effect of Tai Chi with the same frequency and different session duration on the bone mineral density (BMD) of older women. Methods: Healthy older women aged 55-70 years were randomly divided into the short-time group (n=17), long-time group (n=18), and control group (n=17). The BMD of L2-4 and the proximal femur were measured at baseline and after 48 weeks of intervention. Results: From 0 to 48 weeks, the respective BMD values of L2-4 and the femoral neck in the short-time and long-time groups increased by 8.8% and 7.5% (P<0.01) and 8.8% and 12.7% (P<0.01), while the BMD of the greater trochanter in the control group decreased by 3.0% (P<0.05). After 48 weeks, the BMD of L2-4 and the femoral neck was greater in the short-time and long-time groups than the control group (P<0.001). Conclusions: Tai Chi for 30 or 60 minutes five times weekly for 48 weeks improves the BMD of L2-4 and the femoral neck in older women, but does not affect the BMD of the greater trochanter and Ward's triangle. Increasing the exercise duration does not increase the effect of Tai Chi on BMD.

Background: Investigation regarding bone mineral density (BMD) change rule and osteoporosis in many areas of China has been much reported. However, studies regarding BMD change rule and osteoporosis in Guiyang area, China have been rarely reported. Objective: To investigate BMD in adult population in Guiyang area, China and provide the basis for prevention, diagnosis and treatment of osteoporosis. Methods: BMD was measured in 1 334 cases aged 20-79 years from Guiyang area using dual-energy X-ray absorptiometry during 2008-2011. The measurement sites included lumbar vertebrae 1 to 4 lumbar spine, right proximal femur. The peak BMD reduced by 2.0 SD was taken as the diagnosis for osteoporosis. Statistical analysis was performed based on 10-year age group according to gender. Results And Conclusion: The peak BMDs of 60 men and 50 women from Guiyang area appeared in age group of 20-29. Female population aged 20-29 years showed a high incidence of osteoporosis and bone loss. These findings suggest that awareness of osteoporosis prevention should be enhanced for women before 50 years old and men before 60 years old, while for the subsequent years, relevant interventions should be taken to reduce osteoporosis incidence.

To explore the experience of the process of Tai Chi exercise The study was conducted in a local park in Beijing of China where varying numbers of community members gathered to practice Tai Chi every day. Volunteers meeting the inclusion and exclusion criteria were recruited after signed an informed consent form. In-depth interview and the participatory observation were used to know of the real feeling of practicing Tai Chi. The qualitative data obtained from the interviews were analyzed by using Colaizzi seven-step method to find the subjects. Six volunteers having a long-time Tai Chi exercise were recruited in this qualitative study, and their real experience was summarized in the physiological level, psychological level, social level and cultural level. In the physiological level, Tai Chi improves the health and exercise of Tai Chi assists the elderly to develop good living habits. In the psychological level, Tai Chi practice guides the person to inner peace, relieves tension, improves depressive mood state, and makes the elderly regain self worth. In the social level Tai Chi is a good form of community practice. In the cultural level, Tai Chi roots in yin and yang culture and integrates internal and external exercises. Tai Chi is good for body and mind health and the community of practice is very important for practitioners. Tai Chi gains popularity for its benefits to health and psychological adjustments, and its cultural connotation.

To evaluate the evidence for Tai Chi as an intervention to reduce rate of bone loss in postmenopausal women. Literature search using Medline, Science Citation Index, Cochrane databases, China Biological Medicine Database, and additional manual reference searches of retrieved articles and personal libraries. Randomized controlled trials (RCTs), prospective cohort studies, and cross-sectional studies that included Tai Chi as an intervention, and had at least 1 outcome related to measurement of bone mineral density (BMD). Authors critically reviewed studies, evaluated methodologic quality, and synthesized study results in a summary table. Six controlled studies were identified by our search. There were 2 RCTs, 2 nonrandomized prospective parallel cohort studies, and 2 cross-sectional studies. The 2 RCTs and 1 of the prospective cohort studies suggested that Tai Chi-naive women who participated in Tai Chi training exhibited reduced rates of postmenopausal declines in BMD. Cross-sectional studies suggested that long-term Tai Chi practitioners had higher BMD than age-matched sedentary controls, and had slower rates of postmenopausal BMD decline. No adverse effects related to Tai Chi were reported in any trial. Conclusions on the impact of Tai Chi on BMD are limited by the quantity and quality of research to date. This limited evidence suggests Tai Chi may be an effective, safe, and practical intervention for maintaining BMD in postmenopausal women. In combination with research that indicates Tai Chi can positively impact other risk factors associated with low BMD (eg, reduced fall frequency, increased musculoskeletal strength), further methodologically sound research is warranted to better evaluate the impact of Tai Chi practice on BMD and fracture risk in postmenopausal women.

Tai chi may have beneficial effects with respect to balance, falls and non-vertebral fractures. The purpose of this systematic review was to evaluate evidence from controlled clinical trials testing the effectiveness of tai chi for osteoporosis. Systematic searches were conducted on 20 electronic databases. The outcome measures considered for inclusion were changes in bone parameters. Five randomized clinical trials (RCTs) and two controlled clinical trials (CCT) met all inclusion criteria. In postmenopausal women, one RCT found tai chi to be superior for loss of bone mineral density (BMD) compared with sedentary lifestyle, while two other RCTs found no differences between tai chi and exercises or calcium supplementation for BMD. The meta-analysis showed no significant effect of tai chi on BMD change at the spine compared with no treatment in postmenopausal women. One RCT failed to show favorable effects of tai chi compared with resistance training (RT) for total hip BMD in elderly women. A further RCT compared tai chi with RT on bone metabolism and reported favorable effects compared with RT in the elderly. The evidence for tai chi in the prevention or treatment of osteoporosis is not convincing. More rigorous research seems warranted.

Objective: Research the effect of physical activity early on bone density of middle-aged and old women. Method: Ulna and radius bone mineral content (BMC) and bone mineral density (BMD) of middle-aged and old women doing exercise over a period of time early were determined with Bone Mineral Analyzer. Results: (1) the BMC and BMD of exercise group was higher than control group significantly; the BMC and BMD of the two groups decreased with age increasing and the BMC and BMD of the control group decreased faster than the exercise group. (2) compared with the continued exercise group, the BMC and BMD of discontinued exercise group was lower than it significantly. But there was no obvious difference with body building group. Conclusions: (1) the earlier to exercise, the higher to get bone peak; (2) at any time begin doing exercise, it might play active role to maintain fixed bone mineral amount.

: Physical exercise can strengthen the skeleton substantially, provided that one begins exercising at a young age. During skeletal growth, exercise augments weight-bearing bone structure by enhancing periosteal apposition. The largest gains in bone mass tend to be where hydrostatic pressures within extracellular fluid compartments are greatest. This finding suggests that extracellular fluid pressures or fluid shear stress on bone cells provide a stimulus for bone formation. The best exercises for building bone are those involving impact loading of the skeleton. However, recent prospective studies have shown that even impact exercise is not very effective for building bone in adults. In addition, impact exercise can increase the risk of osteoarthritis in older adults. Considering the meager benefits and potential risks of impact exercise, one might question whether it should be prescribed for prevention of osteoporosis. Instead low-impact exercises designed to improve muscle strength and balance may be preferred for prevention of fractures. The goal of the low-impact exercise strategy is to prevent falls rather than to build bone mass. Several biochemical mediators of the mechanical-loading effects on bone have been identified. Foremost among these are prostaglandins and nitric oxide. In addition, parathyroid and growth hormones provide permissive signals for bone mechanotransduction. Finally, studies of inbred strains of mice suggest that the ability of bone to respond to mechanical loads is under genetic control. The Endocrinologist 2000; 10: 164-169 Learning Objectives: * Review the mechanisms by which exercise strengthens the skeleton. * What types of exercise are best, and what is the trade-off with adverse effects of impact exercise? * Consider how hormones and certain drugs influence the actions of exercise on skeletal structure.
