Research on Influence of Aerobic Dancing and Tennis Exercises on Middle-Aged Women’s Bone Mineral Density of Calcaneus

In order to find out the influence of aerobic dancing and tennis exercises on middle-aged women’s bone mineral density of calcaneus, we select the healthy middle-aged women aged 30-50 as test subjects. We use quantitative ultrasonic bone imaging and measurement system to test the subjects’ bone mineral density of calcaneus. The result shows that the stiffness and bone mineral density of aerobic dancing group and tennis group is higher than that of control group. The difference between aerobic dancing group and control group is not obvious, however, the difference between tennis group and control group is very significant (p = 0.000). The risk degree of fracture of aerobic dancing group and tennis group is lower than that of control group, but the aerobic dancing group and control group have no obvious difference, while the difference between tennis group and control group is very obvious, which indicates that the role of playing tennis is better than taking aerobic dancing in enhancing stiffness and bone mineral density and reducing risk degree of fracture.
