弹力带柔性抗阻运动对中老年女性骨密度和跌倒风险指数的影响

Impact of Flexible Resistance Exercise of Elastic Band for Bone Mineral Density and Fall Risk Index in Elderly Women

【目的】探讨弹力带柔性抗阻运动用于中老年女性对其骨密度和跌倒风险指数的影响。【方法】随机选取社区内60例中老年女性作为研究对象，指导其进行弹性带柔性抗阻运动，采用双能X线骨密度仪和平衡训练测试系统对训练前后骨密度和跌倒风险指数进行评估。【结果】中老年妇女经过三个月的弹性带柔性抗阻运动，训练后骨密度（59．84±2．25）g／cm^2明显高于训练前骨密度（55．53±1．84）g／cm^2，训练后跌倒风险指数（1．24±0．45）明显低于训练前指数（2．53±0．47），差异均有统计学意义（P ＜0．05）。【结论】中老年女性连续进行弹性带柔性抗阻运动能有效提高骨密度，降低跌倒风险指数。

[Objective] To explore the impact of elastic band during flexible resistance exercise for bone mineral density （BMD） and fall risk index in elderly women .[Methods]A total of 60 elderly women were ran‐domly selected from a local community .And they were trained with flexible resistance exercise of elastic band . Bone mineral density and fall risk index were evaluated before and after training using dual‐energy X‐ray ab‐sorptiometry and balance training test system .[Results] After 3 months ,BMD after training （59 .84 ± 2 .25） g/cm^2 was significantly higher than BMD before training （55 .53 ± 1 .84） g/cm3 .And the difference was statis‐tically significant （ P 〈0 .05） .After flexible resistance exercise of elastic band ,fall risk index after training （1 .24 ± 0 .45） was significantly lower than that before training （2 .53 ± 0 .47） （ P 〈0 .05） .[Conclusion] In elderly women ,continuous flexible resistance exercise of elastic band can improve bone density ,lower the inci‐dence of osteoporosis and reduce the risk of fall index .
