“…In addition, the contradictory findings may be related to the different ages of the subjects. Compared with previous studies (11,12,23,24), the subjects in the present study were relatively young (mean age 49.7 years). A meta-analysis confirmed our speculation that the effect of exercise on BMD is reduced as the mean subject age increases ( 4).…”

“…Referring to the results of previous studies on the effects of TC and BW on the BMD of humans ( 11 , 12 ), the present study comprised a 3 (number of groups) × 4 (number of measurements) experimental design, with a predicted sample loss rate of approximately 15%. Using G-power software with the effect size set at 0.3, power set at 0.8, and α set at 0.05, the calculated required sample size was at least 90 subjects.…”

“…Aerobic exercise is preferred over resistance training by the middle-aged and older adult populations, as resistance training is considered difficult because it requires the participants to use devices or perform collective activities (10)(11)(12). However, the effect of aerobic exercise on human BMD is controversial.…”

BackgroundThere is a lack of information on whether the positive effect of Tai Chi (TC) and brisk walking (BW) exercise on bone mineral density (BMD) in perimenopausal women remains after exercise cessation. To compare the effects of regular TC and BW exercise on BMD in perimenopausal women and to analyze the maintenance effects after exercise cessation.MethodsThe TC and BW groups performed 48 weeks of exercise. The BMD of the lumbar spine and dominant-side proximal femur was measured in all subjects at weeks 0, 48, 52, and 56.ResultsCompared with baseline, the BMD of the lumbar spine (L2−4) at week 48 increased by 5.05% (P = 0.031) in the TC group, and the BMD of the femoral neck at week 48 increased by 8.23% (P = 0.031) in the BW group. At 4 and 8 weeks after exercise cessation, the BMD of L2−4 in the TC group was still increased by 5.05% (P = 0.041) and 5.05% (P = 0.023), respectively, and the BMD of the femoral neck was still increased by 8.23% (P = 0.018) and 9.41% (P = 0.007), respectively, in the BW group.ConclusionForty-eight weeks of TC exercise significantly increases the BMD of L2−4 in perimenopausal women, and BW exercise significantly increases the BMD of the femoral neck; these effects are maintained at 4 and 8 weeks after exercise cessation. These results suggest that these two exercises reduce the BMD decrease caused by aging.

“…There is practically no evidence of the efficacy of some type of exercise intervention on BMD in AD. Clinical trials aimed at the effects of exercise in older people or postmenopausal women are more frequent [ 86 , 130 , 131 , 132 , 133 , 134 ]. Although the evidence appears to support the assumption that exercise has positive effects on bone status, not all studies provided clear evidence of increased BMD with exercise interventions [ 97 ].…”

Effects of 6-Month Multimodal Physical Exercise Program on Bone Mineral Density, Fall Risk, Balance, and Gait in Patients with Alzheimer’s Disease: A Controlled Clinical Trial

We aimed to determine the short- and medium-term effects of a multimodal physical exercise program (MPEP) on bone health status, fall risk, balance, and gait in patients with Alzheimer’s disease. A single-blinded, controlled clinical trial was performed where 72 subjects were allocated in a 3:1 ratio to an intervention group (IG; n = 53) and control group (CG; n = 19), where the IG’s subjects were admitted to live in a State Reference Center of Alzheimer’s disease, which offers the targeted exercise program, while the CG’s subjects resided in independent living. A multidisciplinary health team assessed all patients before allocation, and dependent outcomes were again assessed at one, three, and six months. During the study, falls were recorded, and in all evaluations, bone mineral density was measured using a calcaneal quantitative ultrasound densitometer; balance and gait were measured using the performance-oriented mobility assessment (POMA), the timed up and go test (TUG), the one-leg balance test (OLB), and the functional reach test (FR). There were no differences between groups at baseline for all outcome measures. The prevalence of falls was significantly lower in the IG (15.09%) than in the CG (42.11%) (χ2 = 5.904; p = 0.015). We also found that there was a significant time*group interaction, with a post hoc Šidák test finding significant differences of improved physical function, especially in gait, for the IG, as assessed by POMA-Total, POMA-Gait, and TUG with a large effect size (ƞ2p = 0.185–0.201). In balance, we found significant differences between groups, regardless of time, and a medium effect size as assessed by POMA-Balance and the OLB (ƞ2p = 0.091–0.104). Clinically relevant effects were observed, although without significant differences in bone health, with a slowing of bone loss. These results show that a multimodal physical exercise program reduces fall risk and produces an improvement in gait, balance, and bone mineral density in the short and medium term in institutionalized patients with Alzheimer’s disease.

Osteopenia is a condition characterized by low bone mineral density (BMD) that increases fracture risk, particularly among postmenopausal women (PMW). This study aimed to determine the effects of Kinect-based VRT on BMD and fracture risk in PMW with osteopenia. The study was a prospective, two-arm, parallel-design, randomized controlled trial. The study enrolled 52 participants, 26 randomly assigned to each group. In the experimental group, Kinect-based VRT was provided thrice weekly for 24 weeks for 45 min/session. Both groups were instructed to engage in a daily 30-min walk outdoors. The fracture risk assessment tool (FRAX) was used to calculate fracture risk, and dual-energy X-ray absorptiometry was used to measure lumbar spine and femur neck BMD. Both variables were assessed at baseline and 24 weeks afterwards. After 24 weeks of Kinect-based VRT, the experimental group showed significant BMD increases in the right and left femoral necks and lumbar spine (p value < 0.001). In the control group, the BMD at the right and left femoral necks showed fewer significant changes (p value < 0.022 and 0.004, respectively). In the control group, lumbar spine BMD did not change (p = 0.57). The experimental group showed significantly lower FRAX scores for hip fracture prediction (HFP) and hip prediction of major osteoporotic (HPMO) at both femoral necks (p value < 0.001) than the control group (p = 0.05 and p = 0.01, respectively), but no significant change at the left femoral neck for HFP (p = 0.66) or HPMO (p = 0.26). These findings indicate that a Kinect-based VRT intervention resulted in significantly increased BMD and a reduced fracture risk, as predicted by HFP and HPMO measurements. These improvements were more pronounced in the experimental group than in the control group. Thus, Kinect-based VRT may be utilized as an effective intervention to improve BMD and reduce fracture risk in postmenopausal women with osteopenia.
