“…In addition, the contradictory findings may be related to the different ages of the subjects. Compared with previous studies (11,12,23,24), the subjects in the present study were relatively young (mean age 49.7 years). A meta-analysis confirmed our speculation that the effect of exercise on BMD is reduced as the mean subject age increases ( 4).…”

“…Investigations into the effect of TC exercise on human BMD have focused on the middle-aged and older female population, and the results are controversial. Cheng et al (11) concluded that 48 weeks of TC (four 70 min sessions/week) significantly improves the BMD of the lumbar spine (L 2−4 ) and the femoral neck in older women (mean age 63.3 years); similar results were achieved in older women (mean age 61.3 years) who performed 48 weeks of 30 min TC sessions five times/week (12). Another study found that performing 60 min TC sessions three or six times/week for 48 weeks significantly increases the BMD of the lumbar spine (L 2−4 ), femoral neck, and greater trochanter in older women (mean age 64.9 years) (9).…”

“…It shows that TC and BW exercises are moderate-intensity exercises. Previous studies by our team have reported that 48 weeks of TC increases the BMD of the lumbar spine and femoral neck in older women, with TC achieving a better effect on the BMD than BW and square dance exercise ( 11 ).…”

“…Aerobic exercise is preferred over resistance training by the middle-aged and older adult populations, as resistance training is considered difficult because it requires the participants to use devices or perform collective activities (10)(11)(12). However, the effect of aerobic exercise on human BMD is controversial.…”

BackgroundThere is a lack of information on whether the positive effect of Tai Chi (TC) and brisk walking (BW) exercise on bone mineral density (BMD) in perimenopausal women remains after exercise cessation. To compare the effects of regular TC and BW exercise on BMD in perimenopausal women and to analyze the maintenance effects after exercise cessation.MethodsThe TC and BW groups performed 48 weeks of exercise. The BMD of the lumbar spine and dominant-side proximal femur was measured in all subjects at weeks 0, 48, 52, and 56.ResultsCompared with baseline, the BMD of the lumbar spine (L2−4) at week 48 increased by 5.05% (P = 0.031) in the TC group, and the BMD of the femoral neck at week 48 increased by 8.23% (P = 0.031) in the BW group. At 4 and 8 weeks after exercise cessation, the BMD of L2−4 in the TC group was still increased by 5.05% (P = 0.041) and 5.05% (P = 0.023), respectively, and the BMD of the femoral neck was still increased by 8.23% (P = 0.018) and 9.41% (P = 0.007), respectively, in the BW group.ConclusionForty-eight weeks of TC exercise significantly increases the BMD of L2−4 in perimenopausal women, and BW exercise significantly increases the BMD of the femoral neck; these effects are maintained at 4 and 8 weeks after exercise cessation. These results suggest that these two exercises reduce the BMD decrease caused by aging.
