全身振动训练对老年女性平衡能力和下肢关节肌力的影响

Effects of Whole-body Vibration Exercise on Balance Ability and Lower Extremity Muscle Strength in Elderly Women

探讨长期振动训练对老年女性动、静态平衡能力及下肢关节肌耐力的影响,为预防老年人跌倒提供干预措施。采用美国Power-Plate振动仪,对13名55-65岁健康老年女性进行24周,3次/周,25min/次（频率30-40Hz,振幅3mm）的无负重全身振动训练。在干预前后采用Good Balance平衡仪测试受试者动、静态平衡能力,使用德国IsoMed 2000等速肌力测试受试者的膝、踝关节屈伸（60、180°/s）等速肌力。结果发现：24周的高频振动训练增强了老年女性动、静态平衡能力,尤其在左右方向上改善效果显著,同时,对膝、踝关节屈、伸肌群的绝对力量、爆发力和耐力也有不同程度的改善。全身振动训练可作为提高老年人平衡能力和肌耐力的一种干预手段预防老年人跌倒的发生,对不习惯主动运动的人群也是可行的锻炼方式。

This paper sets to study on the effect of long-term vibration training on elderly women＇s dynamic and static balance ability and lower limb muscle endurance,so as to provide intervention measures for the prevention of falls in the elderly.With the American Power-Plate tester,13 women aged 55-65 years old were trained in 24 weeks,3times/week,25min/（frequency 30-40Hz,amplitude 3mm）.The Balance Good tester was used to test the dynamic and static balance ability of the subjects,and the knee and ankle flexion and extension（60/S,180/S IsoMed）were used to test the knee and ankle joint strength.The results show that 24 weeks of high frequency vibration training has improved elderly women＇s static and dynamic balance ability,and the improvement is especially obvious on the left and right direction.At the same time,there are also varying degrees of improvement on the absolute power of knee and ankle flexor and extensor,explosive force and endurance.Therefore,whole body vibration training can be used as an effective method to improve the balance ability and endurance of the elderly people.It is also a feasible exercise for the elderly to prevent falls and those who are not used to active exercises.
