Abstract
QUESTION Can physical activity in adults aged 40-65 years enhance strength and balance and prevent falls? DESIGN Systematic review with meta-analysis of randomised clinical trials. PARTICIPANTS Healthy adults aged 40-65 years. INTERVENTION Programs that involved the performance of any physical activity in community settings and workplaces. OUTCOME MEASURES Strength, balance, endurance, and falls rate. RESULTS Twenty-three eligible trials were identified and 17 of these were pooled in the meta-analyses. The meta-analysis of strength outcomes found a moderate effect of physical activity on strength (SMD=0.54, 95% CI 0.38 to 0.70). Larger effects were observed from programs that specifically targeted strength (SMD=0.68, 95% CI 0.49 to 0.87), when compared to those that did not (SMD=0.32, 95% CI 0.09 to 0.55). This difference was statistically significant (effect of strength in meta-regression p=0.045). Physical activity also had a moderate effect on both balance (SMD=0.52, 95% CI 0.24 to 0.79) and endurance (SMD=0.73, 95% CI 0.50 to 0.96). No trials reported effects of physical activity on falls soon after receiving the intervention. A statistically non-significant effect on falls 15 years after receiving a physical activity intervention was found in one trial (RR=0.82, 95% CI 0.53 to 1.26). CONCLUSIONS This review found that muscle strength, balance, and endurance can be improved by physical activity in people aged 40-65 years. There were bigger effects on muscle strength from programs that used resistance exercises, indicating the need to include a resistance training component if strength enhancement is the goal.

Progressive load training for the quadriceps muscle associated with proprioception exercises for the prevention of falls in postmenopausal women with osteoporosis: a randomized controlled trial. Osteoporos Int 2010; 21:589-96. [PMID: 19562243 DOI: 10.1007/s00198-009-1002-2] [Citation(s) in RCA: 46] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/02/2009] [Accepted: 05/22/2009] [Indexed: 11/28/2022]
Abstract
UNLABELLED This study aims to evaluate the effect of 18-week progressive muscular strength and proprioception training program on the muscle strength of the quadriceps, in prevention of falls in postmenopausal women with osteoporosis. The incidence of falls in the intervention group was significantly lower than in the control group (incidence rate ratio (IRR) = 0.263, 95% CI 0.10-0.68). INTRODUCTION This study aims to evaluate the effect of a progressive muscular strength and proprioception training program on the muscle strength of the quadriceps, balance, quality of life, and reduction in the risk of falls in postmenopausal women with osteoporosis. METHODS One hundred sedentary postmenopausal women with osteoporosis, ages ranging from 55 to 75, were selected and randomized into two groups: the intervention group comprised of 50 patients who underwent a 18-week of progressive load training for the quadriceps muscle (50% up to 80% of 1-RM-one maximum repetition) and proprioception training associated to a drug treatment of osteoporosis and the control group that included 50 patients who only underwent a drug treatment of osteoporosis. The muscular strength, balance, functional mobility, and quality of life were evaluated in the beginning and end of the research. The number of falls was evaluated 24 weeks post-treatment. RESULTS Eighty-five patients concluded the research. The program promoted a significant difference among the groups for SF-36 in the eight sub-scales (p <or= 0.0018), Timed Up & Go Test (p < 0.0001), 1-RM test (p < 0.0001), Berg Balance Scale (p < 0.0001) and also a decrease in the number of falls in the intervention group compared to control (IRR = 0.263, 95% CI 0.10-0.68, p = 0.0064). CONCLUSION The association of progressive strength training for the quadriceps and the proprioceptive training is effective for the prevention of falls, increasing the muscle power, the static and dynamic balance and increasing the speed of the motor responses, therefore improving the performance of daily activities.

Exercise interventions to reduce fall-related fractures and their risk factors in individuals with low bone density: a systematic review of randomized controlled trials. Osteoporos Int 2009; 20:2111-25. [PMID: 19421702 DOI: 10.1007/s00198-009-0938-6] [Citation(s) in RCA: 115] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/03/2008] [Accepted: 04/07/2009] [Indexed: 10/20/2022]
Abstract
SUMMARY Exercise can reduce falls and fall-related fractures in healthy individuals; however, evidence for individuals with low BMD is limited. The results from this systematic review indicate that exercise interventions for individuals with low BMD to reduce falls and fractures should include balance, muscle strengthening, and weight-bearing exercises. INTRODUCTION The purpose of this systematic review was to investigate which exercise interventions are effective in individuals with low bone mineral density (BMD; osteopenia or osteoporosis) in reducing (1) falls and fractures and (2) risk factors for falls and fractures. METHODS Databases were searched for relevant studies between 1996 and June 2008. Methodological quality was assessed with the Jadad score and the PEDro scale. RESULTS Of the 1,369 publications found, 23 met the inclusion criteria. Five additional articles were included after checking reference lists and searching author's names and related articles. Interventions with balance exercises reduced falls or fall-related fractures and improved balance in the majority of the studies. Muscle strengthening exercises were effective in improving lower extremity strength and back extensor strength; however, not all RCT's reported positive effects. Bone strength was improved by weight-bearing aerobic exercise with or without muscle strengthening exercise when the duration of the intervention was at least a year. CONCLUSIONS Exercise can reduce falls, fall-related fractures, and several risk factors for falls in individuals with low BMD. Exercise interventions for patients with osteoporosis should include weight-bearing activities, balance exercise, and strengthening exercises to reduce fall and fracture risk.

Abstract
UNLABELLED The aim of this study was to investigate the effect of a 12-month moderate-to-vigorous exercise program combining aerobic and muscle strength training on body composition among sedentary, postmenopausal women. METHODS A randomized controlled trial was conducted. A total of 189 sedentary postmenopausal women (age 50-69 y, body mass index 22-40 kg/m2) were randomly assigned to an exercise (n = 96) or a control group (n = 93). Study parameters measured at baseline, 4 months, and 12 months were as follows: body weight and body height (body mass index), waist and hip circumference (body fat distribution), and dual-energy x-ray absorptiometry (total body fat and lean mass). Differences in changes in study parameters between exercise and control group were examined with generalized estimating equations analysis. RESULTS The exercise program did not result in significant effects on weight, body mass index, and hip circumference. The exercise group experienced a statistically significant greater loss in total body fat, both absolute (-0.33 kg) (borderline) as in a percentage (-0.43%) compared with the control group. In addition, lean mass increased significantly (+0.31 kg), whereas waist circumference (-0.57 cm) decreased significantly compared with the control group. CONCLUSIONS We conclude that a 12-month exercise program combining aerobic and muscle strength training did not affect weight but positively influenced body composition of postmenopausal women. Affecting body fat distribution and waist circumference may have important health implications because it is an independent risk factor in obese but also in nonobese people. Therefore, this study gives further credence to efforts of public health and general practitioners aiming to increase physical activity levels of postmenopausal women.

Abstract
Objective: To examine the effect of exercise therapy on quality of life in postmenopausal women with osteoporosis or osteopenia. Methods: We searched MEDLINE, CINAHL, PEDro, EMBASE and the Cochrane library from January 1966 to March 2007. Two reviewers independently selected all studies that met predetermined inclusion criteria. Randomized controlled trials that used the Short Form 36 of the Medical Outcome Study (SF-36) questionnaire or the Quality of Life Questionnaire of the European Foundation for Osteoporosis (QUALEFFO) as outcome measures were selected. The PEDro Scale was applied to rate the quality of each article. All studies had a quality score above 5/10. Meta-analysis was facilitated by RevMan 4.1. Results: Four randomized controlled trials met the inclusion criteria, involving a total of 256 participants. Results revealed that the exercise groups showed significant improvements in the domains of physical function, pain, role physical and vitality (P<0.05). Furthermore, intervention with combined exercise programmes had better effects on physical function, pain and vitality domains than controls. Group exercise programmes also produced better results in these three domains. A short-duration exercise programme produced more improvement in physical function, role physical and vitality, whereas a long-duration exercise programme resulted in more improvement in physical function and pain domains. Conclusions: This meta-analysis revealed better improvement in physical function, pain, role physical and vitality in the exercise groups. Combined exercise and group exercise programmes showed better outcomes in the physical function, pain and vitality domains, but different durations of exercise programme showed improvement in different domains.

Abstract
OBJECTIVE The aim of this study was to investigate the effects of photoradiation--infrared at 830 nm--used in two doses, on femora of osteopenic rats. BACKGROUND DATA Osteoporosis has recently been recognized as a major public health problem. Based on stimulatory effects of photoradiation on the proliferation of bone cells, we hypothesized that photoradiation would be efficient in improving bone mass in osteopenic rats. METHODS Sixty female animals, divided into six groups, were used: sham-operated control (SC), osteopenic control (OC), sham-operated irradiated with the dose of 120 J/cm(2) (I120), osteopenic irradiated with the dose of 120 J/cm(2) (O120), sham-operated irradiated with the dose of 60 J/cm(2) (I60), and osteopenic irradiated with the dose of 60 J/cm(2) (O60) Animals were 90 days old when operated. Laser irradiation was initiated 8 weeks after operation, and it was performed 3 times a week for 2 months. Femora were submitted to a biomechanical test and to a physical properties evaluation. RESULTS Maximal load of O120 did not show any difference when compared with SC and I120, but it was higher than the O60 group. Wet weight, dry weight, and bone volume of O60 and O120 did not show any difference when compared with SC. CONCLUSION The results of the present study indicate that photoradiation had stimulatory effects on femora of osteopenic rats, mainly at the dose of 120 J/cm.(2) However, further studies are needed to investigate the effects of different parameters, wavelengths, and sessions of applications on ovariectomized rats.

Abstract
OBJECTIVES To investigate whether a 12-week home-based programme of trunk-strengthening exercise could benefit spinal mobility, function and quality of life for osteoporotic and osteopenic postmenopausal women without fracture. DESIGNS Randomized controlled clinical trial. SETTING Department of Physical Therapy in National Taiwan University Hospital. SUBJECTS Twenty-eight postmenopausal women (mean age 60.3+/-9.3 years) diagnosed with osteoporosis or osteopenia without fracture history were recruited for this study. Subjects were randomly assigned into exercise or control groups, each consisting of 14 subjects. INTERVENTIONS The 12-week exercise programme included strengthening routines for the trunk extensor and flexor muscles. The subjects performed three sets of 10 repetitions for each of the exercises, with programmes carried out three times per day at home. MAIN OUTCOME MEASUREMENTS Muscular strength, spinal range of motion (ROM) and motion velocity, Oswestry Disability Questionnaire (ODQ) and quality of life (QOL) were measured before the start and after completion of the exercise programme. RESULTS Statistically significant improvements were demonstrated in spinal ROM and motion velocity in the sagittal and frontal planes for the exercise group (p<0.05). Further, the strength of the trunk flexors and extensors increased after exercise training (p<0.05). ODQ measure was significantly reduced in the exercise group (p<0.05), while the controls showed no significant change. Subjects in the exercise group showed better satisfaction in some domains of the Short-Form-36 Health Survey quality of life questionnaire (p<0.05). CONCLUSIONS This 12-week home-based trunk-strengthening exercise programme could improve trunk mobility and strength, and enhance QOL in osteoporotic and osteopenic postmenopausal women without vertebral fracture. Future study should recruit more cases or more severe subjects to verify the results.

Abstract
The purpose of this study was to assess the effects of a water-based exercise and self-management program on balance, fear of falling, and quality of life in community-dwelling women 65 years of age or older with a diagnosis of osteopenia or osteoporosis. Fifty women with an average age of 73.3 years (range 65.5-82.4, SD 3.9) were randomised to intervention or control groups. The intervention group received a 10-week water-based exercise and self-management program compiled by Community Physiotherapy Services and conducted by a physiotherapist at an aquatic centre twice a week for one hour. The control group did not receive any instructions and were not encouraged to change their physical activity, activities of daily living or social habits during the study. Change in balance, measured using the step test, from baseline to follow-up differed between intervention and control groups, with mean (95% CI) between-group differences of 1.7 (0.9 to 2.6) and 2.1 (1.1 to 3.1) steps on the left and right sides respectively. Between-group differences in score changes were also significant in four of the eight domains of quality of life measured using the Short Form 36 questionnaire (SF36; physical function 8.6 (0.4 to 16.8), vitality 12.0 (2.3 to 21.8), social function, and 14.1 (0.6 to 27.7) mental health 10.2 (2.0 to 18.4)), but not fear of falling measured using the modified falls efficacy scale (0.25 (-0.3 to 0.81). It is concluded that a water-based exercise and self-management program produced significant changes in balance and quality of life, but not fear of falling, in this group of community-dwelling women 65 years of age or older with a diagnosis of osteopenia or osteoporosis.

Abstract
Women who pass menopause face many changes that may lead to loss of health-related fitness (HRF), especially if sedentary. Many exercise recommendations are also relevant for early postmenopausal women; however, these may not meet their specific needs because the recommendations are based mainly on studies on men. We conducted a systematic review for randomised, controlled exercise trials on postmenopausal women (aged 50 to 65 years) on components of HRF. HRF consists of morphological fitness (body composition and bone strength), musculoskeletal fitness (muscle strength and endurance, flexibility), motor fitness (postural control), cardiorespiratory fitness (maximal aerobic power, blood pressure) and metabolic fitness (lipid and carbohydrate metabolism). The outcome variables chosen were: bodyweight; proportion of body fat of total bodyweight (F%); bone mineral density (BMD); bone mineral content (BMC); various tests on muscle performance, flexibility, balance and coordination; maximal oxygen consumption (V-dotO(2max)); resting blood pressure (BP); total cholesterol (TC); high-density lipoprotein-cholesterol; low-density lipoprotein-cholesterol; triglycerides; blood glucose and insulin. The feasibility of the exercise programme was assessed from drop-out, attendance and injury rates. Twenty-eight randomised controlled trials with 2646 participants were assessed. In total, 18 studies reported on the effects of exercise on bodyweight and F%, 16 on BMD or BMC, 11 on muscular strength or endurance, five on flexibility, six on balance or coordination, 18 on V-dotO(2max), seven on BP, nine on lipids and two studies on glucose an one on insulin. Based on these studies, early postmenopausal women could benefit from 30 minutes of daily moderate walking in one to three bouts combined with a resistance training programme twice a week. For a sedentary person, walking is feasible and can be incorporated into everyday life. A feasible way to start resistance training is to perform eight to ten repetitions of eight to ten exercises for major muscle groups starting with 40% of one repetition maximum. Resistance training initially requires professional instruction, but can thereafter be performed at home with little or no equipment as an alternative for a gym with weight machines. Warm-up and cool-down with stretching should be a part of every exercise session. The training described above is likely to preserve normal bodyweight, or combined with a weight-reducing diet, preserve BMD and increase muscle strength. Based on limited evidence, such exercise might also improve flexibility, balance and coordination, decrease hypertension and improve dyslipidaemia.
