“…This is consistent with Lin et al (2012), who reported no change in TRAP5b, a marker of bone resorption, following plyometric exercise in men. Rogers et al (2011), on the other hand, reported a decrease in TRAP5b post-exercise.…”

“…Nonweight-bearing exercise, such as cycling, does not appear to result in a clear pattern of changes of biochemical markers of bone turnover (Guillemant et al 2004;Herrmann et al 2007;Pomerants et al 2008). Two studies examined the effect of high-impact, plyometric exercise (jumping) on markers of bone turnover in men and report inconsistent results: Rogers et al (2011) reported no change in markers of bone formation (osteocalcin and bone ALP) and transient changes in markers of bone resorption (TRAP5b and CTx), while Lin et al (2012) demonstrated an acute increase in osteocalcin and no change in TRAP5b in men.…”

“…(9) The bonederived protein, osteocalcin, for example, has been reported to act on muscle cells to mediate the response to exercise. (41,42) In observational studies, osteocalcin levels increase following exercise (43)(44)(45)(46) and are positively correlated with muscle strength. (47) Therefore, it is possible that bone-derived signals, such as osteocalcin, are directly contributing to the increased risk of BADL disability and future work is necessary to determine whether osteocalcin serves as a mechanistic link connecting bone and disability.…”

Age‐related bone loss is common in older adults. However, the association of low bone mass with incident disability and mortality is not well established. A sample of 738 participants in the Rush Memory and Aging Project (MAP) was evaluated at baseline for bone mineral density (BMD) using quantitative ultrasound at the calcaneus. An annual interview assessed basic activities of daily living (BADL), instrumental activities of daily living (IADL), mobility disability, and history of hip fracture. The associations between baseline BMD and risk of death; incident BADL, IADL, and mobility disability; and hip fracture were investigated using Cox hazard models, adjusting for age, sex, education, race, and body mass index (BMI). The robustness of our findings was evaluated by adjusting for confounding factors and health conditions including joint pain, musculoskeletal medications, smoking status, motor function, global cognition, falls, cardiovascular events, and diabetes. Participants were on average (mean ± SD) 80.9 ± 7.0 years old, 72% female, and 3.8% black, with a baseline BMI of 27.3 ± 5.4 kg/m2, and a baseline of BMD of 0.44 ± 0.14 g/cm2. In models adjusted for age, sex, education, race, and BMI, lower BMD was associated with a higher rate of death (hazard ratio [HR] 1.20; 95% confidence interval [CI], 1.08–1.33), incident BADL disability (HR 1.20; 95% CI, 1.05–1.37), and hip fracture (HR 2.57; 95% CI, 1.72–3.82), but not of IADL disability (HR 1.00; 95% CI, 0.85–1.17) or mobility disability (HR 1.13; 95% CI, 0.97–1.32). The association between BMD and mortality was not significant in fully adjusted models, but the BMD and BADL associations remained significant in models adjusting for both demographic variables and BMD‐modifying health conditions. BMD is associated with incident disability in older adults. © 2020 The Authors. JBMR Plus published by Wiley Periodicals LLC on behalf of American Society for Bone and Mineral Research.

“…This type of exercise has been shown to be an effective method for increasing lean mass in adolescents with Down syndrome, 17 and as bone mass is closely associated with lean mass this is a positive finding. It has also been suggested that in young people the mechanical impact resulting from plyometric exercise is one of the most osteogenic activities, 12 and could enhance the levels of osteocalcin, 18 which is an established and extensively used biochemical marker of bone formation 19 …”

BMC Bone mineral content DS-E Down syndrome, exercise group DS-NE Down syndrome, non-exercise group TLM Total lean mass AIM To determine whether the bone mass of young people with Down syndrome may increase, following a 21-week conditioning training programme including plyometric jumps.METHOD Twenty-eight participants with Down syndrome (13 females, 15 males) aged 10 to 19 years were divided into exercise (DS-E; n=14; eight females, six males mean age 13y 8mo, SD 2y 6mo) and non-exercise (DS-NE; n=14; five females, nine males mean age 15y 5mo, SD 2y 6mo) groups. Total and regional (hip and lumbar spine [L1-L4]) bone mineral content (BMC) and total lean mass were assessed by dual energy X-ray absorptiometry at baseline and after a 25-minute training session performed twice a week. Repeated-measures analyses of variation were applied to test differences between pre-and posttraining values for BMC and total lean mass. Differences between increments were studied with the Student's t-test. Linear regression models were fitted to test independent relationships. RESULTS After the intervention, higher increments in total and hip BMC, and total lean mass, were observed in the DS-E group (all p<0.05). A time·exercise interaction was found for total lean mass (p<0.05). The increment in total lean mass, height, and Tanner stage accounted for almost for 60% in the increment in total BMC in the DS-NE group (p<0.05).INTERPRETATION Twenty-one weeks of training have a positive effect on the acquisition of bone mass in young people with Down syndrome. Down syndrome is a genetic condition accompanied by intellectual disability and more than 80 clinical manifestations, some of them affecting body composition. 1 Lower levels of bone mineral content (BMC) have been observed not only in adults 2-6 but also in children and adolescents with Down syndrome 7,8 compared with their counterparts without Down syndrome. The acquisition of high bone mass during childhood and adolescence is an important factor in preventing osteoporosis later in life. 9,10 Because life expectancy of persons with Down syndrome has increased over recent decades to over 55 years, the incidence of osteoporosis, bone fragility, and related fractures is expected to increase in the coming years.It is well established that physical activity and, specifically, participation in sport during growth has an osteogenic effect on the growing skeleton in children and adolescents without disabilities; 12-14 however, studies have not yet been made of children and adolescents with Down syndrome, 15 who might also benefit from osteogenic exercising. Plyometric training is a type of exercise that requires various jumps in place or rebound jumping, which may increase peak bone mass during adolescence. 16 This type of exercise has been shown to be an effective method for increasing lean mass in adolescents with Down syndrome, 17 and as bone mass is closely associated with lean mass this is a positive finding. It has also been suggested that in young people the mechanical impact result...
