Abstract: OBJECTIVE: Resistive exercises can effectively increase bone mineral density in postmenopausal women, but there is no consensus on the choice of exercise intensity and exercise frequency. This paper evaluates the effect of different resistance training programs on bone mineral density in postmenopausal women based on a network Meta-analysis. 
METHODS: We systematically searched CNKI, WanFang, China Biomedical Database (CBM), ProQuest, PubMed, Cochrane Library, Embase, and Web of Science for literature regarding the use of resistance training programs to improve the bone mineral density of postmenopausal women. The search time was from database inception to May 2022. The two reviewers dependently screened the included literature, extracted relevant data, evaluated the risk quality of the literature using the Cochrane manual and the PEDro scale, and conducted a Meta-analysis using Stata 16.0. 
RESULTS: A total of 20 studies including 1 087 subjects were included. Results from the network Meta-analysis showed that (1) compared with the control group, the medium-intensity resistance training was significantly better in improving lumbar and femoral neck bone mineral density (P < 0.05). In terms of improving the bone mineral density of the total hip and femoral greater trochanter, the moderate-intensity resistance training was better, but there was no significant difference among the groups (P > 0.05). (2) In terms of exercise frequency, the 3 days/week moderate-intensity resistance exercise was better than 2 days/week moderate-intensity resistance exercise to improve the bone mineral density of the lumbar vertebra. Moreover, at the exercise frequency of 3 days/week, moderate-intensity exercise was significantly better than low- and high-intensity exercises (P < 0.05). (3) The cumulative probability ranking results showed that the moderate-intensity resistance training of 3 days/week was the best in improving the bone mineral density of the lumbar vertebra, femoral neck, total hip, and greater trochanter. 
CONCLUSION: Based on the current evidence, moderate-intensity resistance exercise with a frequency of 3 days per week can be selected to improve the reduced bone mineral density in postmenopausal women. The above conclusions need to be verified by more high-quality research.
