弹力带柔性抗阻训练对中老年女性骨密度和跌倒风险指数的影响

Influence of Flexible Resistance Training with Resilience Belt on Bone Density and Possibility of Falling Among Middle-aged and Senior Women

探讨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,为大众健身缓减骨质疏松症提供理论依据.以25名56～72岁中老年女性健身爱好者为研究对象,受试者均无明确诊断的心肺、脑等内脏器官疾病.在试验中,以弹力带柔性抗阻练习为主要方式,以增加肌肉力量为目的,针对受试者全身的大肌肉群进行分周期、分频度测试.受试者每周进行强度为16RM的训练3-5次,共18周.利用双能X线骨密度仪、平衡训练和测试系统检测受试者的骨密度和跌倒风险指数.采用spss16.0统计学软件计算（-x）±s,配对T检验进行差异性比较.18周弹力带柔性抗阻训练后中老年女性训练者的各项骨强度较实验前均有显著性增高,跌倒风险指数较实验前有非常显著性降低,参训者的平衡能力得到提升,最终有效的达到预防中老年女性人群摔倒和大大降低骨折发生的目的.

The exploration of the influence of the flexible resistance training with resilient belt on the bone density and possibility of falling among middle-aged and senior women could provide theoretical basis for the fact that the public fitness relieved osteoporosis. Taking 25 middle-aged and senior women （aged from 56 to 72 years old） hav- ing no diagnosed diseases in hearts, lungs or brains as the subjects, an experiment was made with the aim to in- crease the strength of muscles and use the resilient belt to practice resistance training on the muscle groups all over the body such as back, upper arms, belly, legs and hips. The subjects took three to five times a week training inten- sity of 16RM with the duration of time of 80 minutes plus an interval of 30 minutes. The training lasted for 18 weeks. The double function X-ray bone density machine and the balance training and testing system were used to test the bone density and the falling possibility of the subjects. Statistics software of spssl6.0 was used to calculate -x ±i S and the differences were compared through the matching T examination. After 18 weeks of the flexible resistance training with resilient belt, the bone density of the middle-aged and senior female women was greatly improved and the falling possibility was remarkably reduced, compared with the situation before the experiment. The balancing ability of the subjects was also been improved and eventually the falling and bone fracture of old women were effec- tively prevented.
