“…The simplified Tai Chi exercise not only keeps the original essence of the traditional Tai Chi improving physical function, but also is more easily accessible to older adults [16]. The resistance training in the simplified Tai Chi exercise has been proven to have a positive impact on alleviating bone mass loss [16]. The present study also showed that the simplified Tai Chi improved the FMS scores, which may be attributed to its main function improving physical function.…”

“…Physical exercise has been proven to improve muscular strength and balance ability for fall prevention in older adults [14, 15]. Tai Chi is a safe, health-enhancing exercise and is suitable for older adults due to the features of gentleness and softness [16]. Tai Chi has been extensively studied and its positive impact includes improving postural stability and alleviating degeneration of muscular strength in older adults [17].…”

“…The traditional Tai Chi routine is lengthy and complex, which restricts those people who lack the time, commitment, or mobility to exercise in groups under the supervision of an instructor. The simplified Tai Chi exercise not only keeps the original essence of the traditional Tai Chi improving physical function, but also is more easily accessible to older adults [16]. The resistance training in the simplified Tai Chi exercise has been proven to have a positive impact on alleviating bone mass loss [16].…”

Background. The present study aimed to evaluate and compare the effect of two different types of Tai Chi programs on the Functional Movement Screening (FMS) in older adults. Methods. Ninety older adults (65.5 ± 4.6 years old) who met the eligibility criteria were randomized into three different groups based on a ratio of 1 : 1 : 1: a traditional Tai Chi exercise (TTC), a simplified Tai Chi exercise (TCRT), or a control group (routine activity). The FMS consisted of the deep squat, hurdle step, in-line lunge, shoulder mobility, active straight leg rise, trunk stability push-up, and rotatory stability, which was used to measure physical function before the present study and after six months of Tai Chi interventions. Results. Seventy-nine participants completed the present study (control = 27, TTC = 23, and TCRT = 29). Significant improvement on the FMS tests between the baseline and after the six-month intervention was observed in both Tai Chi programs, whereas no significant improvement was observed in the control group. In addition, participants in the TCRT group demonstrated greater improvement than those in the TTC group. Conclusions. The TCRT is more effective in improving the physical function in older adults when compared to the traditional Tai Chi modality, particularly for improving balance.

“…The majority of included studies (44 trials) had a moderate quality [8,10,11,14,26,28,30,[32][33][34][35] [35,65,88,89], whilst two studies prescribed jumping [25,84] and four groups performed non-WB + RT [29,60,71,80]. There was a significant increase in BMD favouring exercise interventions over control groups (P < 0.001, SMD = 0.37, 95%-CI: 0.25-0.50), with a substantial level of heterogeneity between trials (I 2 =73.2 %, Q = 262.43, degrees of freedom (df)=78, P < 0.001; ▶Figure 1).…”

Effect of different types of exercise on bone mineral density in postmenopausal women: A systematic review and meta-analysis

Postmenopausal women face a high risk of bone loss. Exercise has a beneficial effect to prevent bone deterioration in elderly women. This study was conducted to investigate the effect of different types of exercise on bone mineral density at the lumbar spine and femoral neck in postmenopausal women.This review followed the guidelines recommended by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement and was registered in advance in the International prospective register of systematic reviews (PROSPERO) (ID: CRD42018095097). Literature searches with no language restriction were conducted through PubMed, Scopus, Web of Science, Cochrane, Science Direct, Eric, ProQuest, and Primo up to March 1 2019 using related MeSH terms and key words. Controlled trials with ≥ 6 months intervention duration among postmenopausal women that comprised at least one exercise and one control group were included in this study. Meta-analyses were performed using random-effects models and effect sizes calculated using the standardised mean difference (SMD). Seven categories of exercise were classified and used in sub-group analyses. P-values < 0.05 were considered statistically significant.Seventy-five studies were included, assessing the bone mineral density of 5300 (range of mean age: 50–79) postmenopausal women who performed exercise or control protocols. Interventions ranged from six to 30 months and the most common exercise frequency was three sessions per week. The majority of studies employed multicomponent exercise interventions. Results of the meta-analyses showed a significant effect (SMD = 0.37, 95%-CI: 0.25–0.50) for lumbar spine and femoral neck (SMD = 0.33, 0.23–0.43) (all P < 0.0001).Sub-group analysis revealed large heterogeneity and no significant differences in exercise categories at the lumbar spine (P = 0.36) and femoral neck (P = 0.43). However, weight-bearing exercise + jumping + resistance training exhibited the largest effect (SMD = 0.71, 0.33–1.10) at the lumbar spine. Moreover, non-weight-bearing combined + resistance exercise revealed the largest effect (SMD = 0.68, 0.16–1.19) at the femoral neck. Contrary to our expectation, jumping alone indicated a greater decrease in bone mineral density compared to the control group at both the lumbar spine (−0.07, −0.46–0.32) and femoral neck (−0.12, −0.62–0.37).In conclusion, the current study provided a positive small effect of exercise on bone mineral density at the lumbar spine and femoral neck. Findings from sub-group analyses suggest larger benefits in multicomponent interventions that include weight-bearing and resistance training exercises compared to them as a single mode of exercise. Unequal numbers of studies were found for each category (e. g. jumping: two trials; dynamic resistance training: 15 trials), affecting the comparison between them. Therefore, findings should be interpreted with caution; they are not yet generalizable to specific types of exercise.

The aim of this systematic review and meta-analysis was (1) to determine exercise effects on bone mineral density (BMD) in postmenopausal women and (2) to address the corresponding implication of bone and menopausal status or supervision in postmenopausal women. A comprehensive search of eight electronic databases according to the PRISMA statement up to August 9, 2022, included controlled exercise trials ≥ 6 months. BMD changes (standardized mean differences: SMD) at the lumbar spine (LS), femoral neck (FN), and total hip (TH) were considered as outcomes. Study group comparisons were conducted for osteopenia/osteoporosis versus normal BMD, early versus late postmenopausal women, and predominantly supervised versus predominantly non-supervised study arms. We applied an inverse heterogeneity (IVhet) model. In summary, 80 studies involving 94 training and 80 control groups with a pooled number of 5581 participants were eligible. The IVhet model determined SMDs of 0.29 (95% CI: 0.16-0.42), 0.27 (95% CI: 0.16-0.39), and 0.41 (95% CI: 0.30-0.52) for LS, FN, and THBMD, respectively. Heterogeneity between the trial results varied from low (I 2 = 20%, TH BMD) to substantial (I 2 = 68%, LS-BMD). Evidence for publication bias/small study effects was negligibly low (FN-, TH-BMD) to high (LSBMD). We observed no significant differences (p > .09) for exercise effects on LS-, FN-, or TH-BMD-LS between studies/study arms with or without osteopenia/osteoporosis, early versus late postmenopausal women, or predominantly supervised versus non-supervised exercise programs. Using robust statistical methods, the present work provides further evidence for a positive effect of exercise on BMD in postmenopausal women. Differences in bone status (osteopenia/osteoporosis versus normal bone), menopausal status (early versus late postmenopausal), and supervision (yes versus no) did not significantly affect the exercise effects on BMD at LS or proximal femur.
