After menopause, there is an imbalance between bone formation and resorption activity, which could lead to postmenopausal osteopenia or osteoporosis. Resistance training (RT) can induce mechanical stress on bone which is necessary for bone remodeling and angiogenic-osteogenic response. This systematic review aims to assess the effects of RT on bone microcirculation and bone turnover markers (BTMs) in postmenopausal women with osteopenia or osteoporosis. We conducted a comprehensive search for related studies published up to April 2023 to identify eligible articles. Out of 316 articles identified, the full texts of 69 articles were screened. There is not any study which consider the effect of resistance exercises on bone microcirculation in PMOP women, but four articles aseess the effect of RT on BTMs and were reviewed. The quality of the articles was assessed by using the Physiotherapy Evidence Database (PEDro) scale. In one study, after 6 and 12 months of RT, bone formation and bone resorption biomarkers decreased not significantly. According to another study, bone formation and resorption biomarkers increased significantly after 3-months RT. Two other studies reported increases in biomarkers of bone formation along with decreases of biomarkers in bone resorption after 6-months of RT, but these were not significant. However, these results suggest that RT had some beneficial effects on BTMs but it is not an effective tool for modifying BTMs in women with osteoporosis or osteopenia. This may be due to the site-specific skeletal stimulation that RT provides. In addition considering the effect of RT on microcirculation of bone are important. So, there is a need for further, high-quality studies in this field. [ABSTRACT FROM AUTHOR]
