| Objective: To carry out a 40-week training intervention in older adults aged 60-75 years, and to compare the effects of vibration training and traditional strength training in promoting bone mineral density. The experiment aimed to provide the basis for the formulation of exercise prescription for the prevention and treatment of osteoporosis in old people. Methods: 52 volunteers were selected and divided into the traditional strength training group, the vibration training group and the control group. Different training plans were implemented for each group. At baseline, end of training, and 8 months after training, all subjects were tested for bone mineral density of L2-L4, right femoral neck, Ward triangle area and the greater trochanter. Results: In the traditional strength training group, BMD of the right femoral neck and the Ward triangle area increased significantly after the training. The results showed that there was gender difference, and the effect was greater in males compared with females. In the vibration training group, bone mineral density at each site measured increased significantly, and there was no gender difference. Eight months after training, bone density of greater trochanter and Ward triangle area of the vibration training group was significantly higher than that of the control group, but there were no significant differences between the two groups for bone density of other sites. Conclusion: Traditional strength training had significant effect on bone mineral density of proximal femur in males, but not in females. Vibration training could promote bone density of each site measured in the subjects, and there was no gender difference. The effect of vibration training in increasing bone mineral density and the continuing effect after training stop were significantly better than those of traditional strength training. |
