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 majority of the 88 intervention groups employed aerobic exercise as the main component of their intervention, with walking and/or jogging the most common types (Nelson et al, 1991;Grove and Londeree, 1992;Lau et al, 1992;Bloomfield et al, 1993;Hatori et al, 1993;Martin and Notelovitz, 1993;Bassey and Ramsdale, 1995;Kohrt et al, 1995Kohrt et al, , 1997Prince et al, 1995;Brooke-Wavell et al, 1997Ebrahim et al, 1997;Bassey et al, 1998;Ryan et al, 1998;Hans et al, 2002;Sugiyama et al, 2002;Yamazaki et al, 2004;Korpelainen et al, 2006;Wu et al, 2006;Evans et al, 2007;Silverman et al, 2009;Sakai et al, 2010;Marques et al, 2011c;Tartibian et al, 2011;Basat et al, 2013).

Effect of Exercise Training on Bone Mineral Density in Post-menopausal Women: A Systematic Review and Meta-Analysis of Intervention Studies

Osteoporosis is a major health problem in post-menopausal women (PMW). Exercise training is considered a cost-effective strategy to prevent osteoporosis in middle aged-older people. The purpose of this study is to summarize the effect of exercise on BMD among PMW. A comprehensive search of electronic databases was conducted through PubMed, Scopus, Web of Science, Cochrane, Science Direct, Eric, ProQuest, and Primo. BMD changes (standardized mean differences: SMD) of the lumbar spine (LS) femoral neck (FN) and/or total hip were considered as outcome measures. After subgroup categorization, statistical methods were used to combine data and compare subgroups. Seventy-five studies were included. The pooled number of participants was 5,300 (intervention group: n = 2,901, control group: n = 2,399). The pooled estimate of random effect analysis was SMD = 0.37, 95%-CI: 0.25-0.50, SMD = 0.33, 95%-CI: 0.23-0.43, and SMD = 0.40, 95%-CI: 0.28-0.51 for LS, FN, and total Hip-BMD, respectively. In the present meta-analysis, there was a significant (p < 0.001), but rather low effect (SMD = 0.33-0.40) of exercise on BMD at LS and proximal femur. A large variation among the single study findings was observed, with highly effective studies but also studies that trigger significant negative results. These findings can be largely attributed to differences among the exercise protocols of the studies. Findings suggest that the true effect of exercise on BMD is diluted by a considerable amount of studies with inadequate exercise protocols.

“…In terms of the DFT implementation method, the subjects were requested to stand on one leg with both hands on the sides (on each leg, right and left, for 1 min and 3 times a day [morning, noon, and night]) [6,23]. In addition, for safety, the subjects were allowed to grab the wall, desk, or handrail.…”

Aims: In this study, we analyzed the effect of concentrated bovine-milk whey active protein (CBP) supplementcombined dynamic flamingo therapy (DFT) on bone metabolism and bone-related factors.Methods: Subjects were menopausal women over 65 years of age, and they were divided into 3 groups C, DFT, and CBP-combined DFT (DFT-CBP) and analyzed for 2 months. Results:The deoxypyridinoline (DPD) bone marker showed only a 27.7% decreased value in the DFT-CBP group after 2 months of treatment initiation, in comparison with the value before treatment (p<0.01). However, the calcitonin was found with significant changes in all groups, but the DFT and DFT-CBP groups demonstrated a similar pattern of changes. The DFT-CBP group showed a 30.1% increased value after 1 month of treatment initiation, in comparison with the value before treatment, and a 37.1% decreased value after 2 months of treatment initiation (p<0.001, in each).Discussion: This study demonstrated the synergistic effect of CBP supplement and an exercise load such as DFT. On the basis of these results, with the presence of a synergistic effect of a lightly loaded exercise and supplementation, bone improvement in menopausal women can be expected. [18][19][20]. Accordingly, at present, no consensus has been reached [15,21]. In contrast, bone improvement has been reported when nutritional intake is combined with exercise, in which the combined use of CBP supplement and DFT results in a safer, positive, and synergistic effect on bone improvement. ConcentratedThis study examined the impact of DFT combined with CBP supplement on bone metabolism and bone-related factors among menopausal women. The present study also aimed to clarify the manner in which the synergistic effect of DFT and CBP supplements causes changes in bone metabolism. Materials and Methods SubjectsSubjects were 35 menopausal women more than 65 years of age (71.9 ± 6.3 yr), who did not have any major illness or a history of illness
