Tai Chi Rouli Ball, a traditional Chinese sport, is thought to have beneficial effects on physical health, but its impact on bone health in perimenopausal women is not well understood. Methods This study involved a randomized controlled trial with 52 perimenopausal women aged 45-55 years from community senior centers. Participants were divided into two groups: the Tai Chi Rouli Ball group and the control group. Baseline assessments of bone density, bone mineral content (BMC), and bone metabolism markers, including estrogen levels, were conducted. The Tai Chi Rouli Ball group underwent regular training for a specific period, while the control group did not receive any intervention. Post-experiment assessments were then compared to the baseline. Results Post-intervention, the Tai Chi Rouli Ball group showed a significant increase in spine bone density and BMC in various body parts, including the whole body, trunk/torso, and spine, compared to the control group. Bone metabolism indicators also improved, with increased levels of estrogen and a decrease in follicle-stimulating hormone (FSH) and luteinizing hormone (LH). Calcium levels showed a significant increase, while other markers like alkaline phosphatase (ALP), phosphorus (P), and magnesium (Mg) had non-significant changes. Conclusions Tai Chi Rouli Ball exercise may positively influence bone health by improving bone density, BMC, and altering bone metabolism markers in perimenopausal women. These findings suggest that Tai Chi Rouli Ball could be a viable non-pharmacological approach to prevent osteoporosis in this demographic.
