Plain language summary
Fragility fractures are associated with both personal and healthcare system burdens. It is well established that bone loss leading to osteopenia or osteoporosis results in increased risk of fractures. Prescription of pharmacological agents is commonly used as first-line treatment. The aim of this study was to evaluate the effect of the Osteo-cise: Strong Bones for Life program on the patient-reported outcomes including health related quality of life (HRQoL), osteoporosis knowledge and osteoporosis attitudes and beliefs. This study is a secondary analysis of an 18-month randomised controlled trial in which participants were randomly allocated to either the community-based Osteo-cise: Strong Bones for Life program (‘Osteo-cise’) or a standard care control group. Results showed that there were no significant effects on HRQoL, osteoporosis knowledge or osteoporosis attitudes and beliefs compared with usual care. However, per protocol analyses revealed that those most adherent to exercise training did experience significant improvements in both HRQoL and osteoporosis knowledge compared with usual care. Authors concluded that their findings highlight the need to identify strategies that promote long-term adherence to multifaceted exercise programs in community-dwelling older adults.
Abstract
UNLABELLED This study identified that an 18-month community-based, multifaceted, exercise program consisting of resistance, weight-bearing impact, and balance/mobility training combined with osteoporosis education and behavioural support can improve health-related quality of life (HRQoL) and osteoporosis knowledge in older adults at risk of fracture, but only for those adherent to the exercise regime. PURPOSE To evaluate the effects of an 18-month community-based exercise, osteoporosis education and behaviour change program (Osteo-cise: Strong Bones for Life) on HRQoL, osteoporosis knowledge and osteoporosis health beliefs. METHODS This was a secondary analysis of an 18-month randomised controlled trial in which 162 older adults aged ≥ 60 years with osteopenia or increased falls/fracture risk were randomized to the Osteo-cise program (n = 81) or control group (n = 81). The program consisted of progressive resistance, weight-bearing impact and balance training (3 days/week); osteoporosis education to facilitate self-management of musculoskeletal health and behavioural support to enhance adherence to exercise. HRQoL, osteoporosis knowledge and osteoporosis health beliefs were assessed using the EuroQoL questionnaire (EQ-5D-3L), Osteoporosis Knowledge Assessment Tool and Osteoporosis Health Belief Scale, respectively. RESULTS Overall, 148 participants (91%) completed the trial. Mean exercise adherence was 55% and mean attendance for the three osteoporosis educational sessions ranged from 63-82%. After 12 and 18 months, there were no significant effects of the Osteo-cise program on HRQoL, osteoporosis knowledge or health beliefs relative to controls. Per protocol analyses (≥ 66% exercise adherence; n = 41) revealed a significant net benefit in EQ-5D-3L utility for the Osteo-cise group relative to controls after 12 months (P = 0.024) and 18 months (P = 0.029) and a significant net improvement in osteoporosis knowledge scores at 18 months (P = 0.014). CONCLUSION This study supports the importance of adherence to exercise regimes, as adherence to the Osteo-cise: Strong Bones for Life program was associated with improvements in HRQoL and osteoporosis knowledge in older adults at increased risk for falls and fractures.

Plain language summary
Sarcopenia is the loss of muscle mass, strength and function related to ageing. It can lead to problems such as reduced mobility and an increased risk of falls in older people. Regular exercise may slow down the deterioration of muscle, but there is no consensus on what type of exercise is best. This study, carried out in Taiwan, aimed to compare different types of exercise on the fat free mass, muscle strength and physical performance in adults over the age of 50 who were at a high risk of bone fractures. The participants were split into two groups and assigned to either the integrated care (IC) or lower extremity exercise (LEE) group for 12 weeks. All participants received education including home-based exercise. The IC group consisted of different modalities of exercise which included upper- and lower-body training with resistance bands and balance training, while the LEE group performed machine-based leg exercises. Fat free mass, muscle strength, and physical performance were measured at the start and end of the study. Both groups demonstrated significant improvements in fat free mass, muscle strength (4 indicators) and physical performance (3 indicators), with the two exercises regimes giving similar results. Both men and women saw similar benefits from regular exercise. The authors concluded that both regimes were equally effective in decreasing fat mass and increasing physical performance, muscle mass and strength. However, the IC group required less equipment and therefore could be more financially feasible in a community setting.
Abstract
BACKGROUND The deterioration of the musculoskeletal system imposes significant impact on physical activity. Exercise is an important strategy which minimizes these changes. It is not clear which type of exercise provides better improvement on low physical performance, low muscle mass and low strength of sarcopenia. We aim to develop an integrated care (IC) model and compare its relative efficacy in limb fat free mass, muscle strength, and physical performance with low extremities exercise (LEE) in community dwelling older adults with high risk of fractures (Fracture Risk Assessment Tool (FRAX®)) ≧3% for hip fracture, ≧20% for major osteoporotic fracture or 1-min osteoporosis risk test (≧1 point) or fall (≧2 falls in previous year). METHODS Patients were assigned randomized to participate in either IC or LEE group (n = 55 each) for 3 months. All participants received education including home-based exercise. The IC group consisted of different modalities of exercise while the LEE group performed machine-based low extremities exercise. Fat free mass, muscle strength, and physical performance were measured at their baseline and 3-months follow-up. RESULTS Mean age was 73.8 ± 7 years with 69.1% women. Entire cohort demonstrated significant increment in fat free mass, muscle strength (4 indicators) and physical performance (3 indicators). However, between group differences were not significant. CONCLUSION With regular supervise exercise; both groups are equally effective in decreasing fat mass and increasing physical performance, muscle mass and strength. However, the IC group required fewer resources and thus more financially feasible in a community setting.

Plain language summary
Fractures in older people are a huge public health challenge. Low bone strength in childhood is associated with a higher fracture risk in later life. Weight-bearing activities during childhood can improve muscle and bone strength, potentially reducing the risk of falls and fractures in later life. This study looked at the impact of frequent exercise sessions on bone strength in children aged 8-10 years. 295 Danish school children were divided into three groups: a small-sided ball game group (SSG), a circuit strength training group (CST) or a control group. Exercise sessions lasted for 40 minutes, three times a week for 10 months. Scans were used to determine bone mineral density (BMD), bone mineral content (BMC) and lean body mass (LBM). A variety of tests to determine muscular fitness were carried out at the beginning and end of the study. Both exercise groups saw significant improvements in BMD. Both training types resulted in significant improvements in postural balance and jump length. No differences between the groups were observed for sprint performance or LBM. The authors concluded that 40 min sessions 3 times a week with SSG or CST over a full school year improves bone mineralisation and several aspects of muscular fitness of children aged 8-10 years, suggesting that well-organised physical education classes can contribute positively to musculoskeletal health in young children.
Abstract
OBJECTIVES We investigated whether musculoskeletal fitness of school children aged 8-10 years was affected by frequent intense PE sessions. DESIGN AND PARTICIPANTS 295 Danish school children aged 8-10 years were cluster randomised to a small-sided ball game group (SSG) (n=96, four schools, five classes), a circuit strength training group (CST) (n=83, four schools, four classes) or a control group (CON, n=116, two schools, five classes). INTERVENTION SSG or CST was performed 3×40 min/week over 10 months. Whole-body dual-energy X-ray absorptiometry (DXA) scans were used to determine areal bone mineral density (aBMD), bone mineral content (BMC) and lean body mass (LBM). Flamingo balance, standing long jump and 20-m sprint tests were used to determine muscular fitness. RESULTS Analysis of baseline-to-10 months change scores showed between-group differences in favour of the interventions in whole-body aBMD (SSG vs CON: 8 mg/cm2, 95% CI 3 to 13; CST vs CON: 7 mg/cm2, 95% CI 2 to 13, p<0.05) and leg BMC (SSG vs CON: 11 g, 95% CI 4 to 18; CST vs CON: 11 g, 95% CI 3 to 18, p<0.05). SSG had higher change scores in leg aBMD compared with CON and CST (SSG vs CON: 19 mg/cm2, 95% CI 11 to 39, p<0.05; SSG vs CST: 12 mg/cm2, 95% CI 3 to 21, p<0.05), and CST had higher change scores in whole-body BMC compared with CON (CST vs CON: 25 g, 95% CI 10 to 39, p<0.05). Both training types resulted in higher change scores in postural balance (SSG vs CON: 2.4 fewer falls/min, 95% CI 0.3 to 4.5, CST vs CON: 3.6 fewer falls/min, 95% CI 1.3 to 5.9, p<0.05) and jump length (SSG vs CON: 10%, 95% CI 5 to 16%; CST vs CON: 9%, 95% CI 3 to 15%, p<0.05). No between-group differences were observed for sprint performance or LBM (p>0.05). CONCLUSIONS In conclusion, 3×40 min/week with SSG or CST over a full school year improves bone mineralisation and several aspects of muscular fitness of children aged 8-10 years, suggesting that well-organised intense physical education classes can contribute positively to develop musculoskeletal health in young children.

Plain language summary
Bone mineral density (BMD), muscle strength, and balance are all important aspects of musculoskeletal health. The aim of the study was to describe associations between objectively‐measured physical activity and sedentary time and musculoskeletal health outcomes in middle‐aged women. The study is a cross-sectional analysis of data from a population-based sample of 309 women with an age range between 36 and 57 years. Results indicate that in middle‐aged women, greater total physical activity was associated with better musculoskeletal health. Moderate-to-vigorous physical activity appears more important than light physical activity or sedentary time for many musculoskeletal outcomes in middle‐aged women. Authors conclude that their findings are important for developing interventions to improve habitual physical activity that are targeted at improving musculoskeletal health amongst women in midlife when an accelerated process of decline in BMD, muscle strength, and balance begins.
Abstract
Associations between physical activity and time spent sedentary and musculoskeletal outcomes remain unclear in middle-aged adults. This study aimed to describe associations between objectively-measured physical activity and sedentary time and musculoskeletal health outcomes in middle-aged women. This cross-sectional study from a population-based sample of 309 women (age 36 to 57 years) examined associations of total physical activity (accelerometer counts/min of wear time), and time spent sedentary, in light physical activities and moderate-to-vigorous physical activities (MVPA) (by Actigraph GT1M accelerometer) with lumbar spine (LS) and femoral neck (FN) bone mineral density (BMD) (by dual-energy X-ray absorptiometry), lower limb muscle strength (LMS), and functional mobility and balance tests (timed up and go test [TUG], functional reach test [FRT], lateral reach test [LRT], and step test [ST]) using linear regression. Total physical activity was beneficially associated with FN BMD (values are β; 95% CI) (0.011 g/cm2 ; 95% CI, 0.003 to 0.019 g/cm2 ), LMS (2.13 kg; 95% CI, 0.21 to 4.06 kg), and TUG (-0.080 s; 95% CI, -0.129 to -0.030 s), after adjustment for confounders. MVPA was also beneficially associated with FN BMD (0.0050 g/cm2 ; 95% CI, 0.0007 to 0.0094 g/cm2 ), LMS (1.48 kg; 95% CI, 0.45 to 2.52 kg), ST (0.12 steps; 95% CI, 0.02 to 0.23 steps), and TUG (-0.043 s; 95% CI, -0.070 to -0.016 s). Associations between MVPA and LMS, TUG and ST persisted after further adjustment for sedentary time. Only TUG was associated with sedentary time, with a detrimental effect (0.075 s; 95% CI, 0.013 to 0.137 s) and this did not persist after further adjustment for MVPA. Light physical activity was not associated with any outcome. MVPA appears more important than light physical activity or sedentary time for many musculoskeletal outcomes in middle-aged women. This needs to be considered when developing interventions to improve habitual physical activity that aim to improve musculoskeletal health. © 2016 American Society for Bone and Mineral Research.
