摘　　要：目的探讨不同频率全身振动训练对老年人动静态平衡能力及核心稳定性的影响。方法2018年1月至6月,老年人80例随机分成30 Hz组(n=40)和45 Hz组(n=40),分别接受30 Hz和45 Hz全身振动训练,共12周。训练前后,测量最大前后倾压力中心(COP)距离/足长比、单脚闭眼站立时间、闭眼30s安静站立COP移动轨迹长、30s连续站立坐下次数和计时起立-行走测试(TUGT)。结果训练后,两组最大前后倾COP距离/足长比、单脚闭眼站立时间和30 s连续站立坐下次数均显著增加(t>7.359,P<0.001),45Hz组高于30Hz组(|t|>2.271,P<0.05);闭眼30s安静站立COP移动轨迹长和TUGT时间显著减少(t>6.631,P<0.001),45Hz组小于30Hz组(t>2.171,P<0.05)。结论12周30Hz和45Hz全身振动训练均可提高老年人动静态平衡能力,增强核心稳定性,改善移动能力,以预防老年人跌倒发生,45 Hz全身振动训练效果更佳。Objective To investigate the effects of different frequency whole-body vibration training on dynamic and static balance ability and core stability for the old adults.Methods From January to June,2018,80 old subjects were randomly divided into 30 Hz group(n=40)and 45 Hz group(n=40),who accepted 30 Hz and 45 Hz whole-body vibration training,respectively,for twelve weeks.They were measured with the maximum distance of center of pressure(COP)forward and backward,the time standing on single foot with eye closing,the length of track of COP as standing for 30 seconds,the standing and sitting times within 30 seconds and the Timed Up and Go Test(TUGT)before and after training.Results The maximum distance of COP forward and backward,the time standing on single foot with eye closing and the standing and sitting times within 30 seconds increased after training in both groups(t>7.359,P<0.001),and was more in the 45 Hz group than in the 30 Hz group(|t|>2.271,P<0.05).The length of track of COP as stand ing for 30 seconds and the time of TUGT decreased after training in both groups(t>6.631,P<0.001),and was less in the 45 Hz group than in the 30 Hz group(t>2.171,P<0.05).Conclusion Both 30 Hz and 45 Hz whole-body vibration training can improve the dynamic and static balance ability,the core stability and mobility for old adults,to prevent them from falls.However,it seems more effective for the 45 Hz whole-body vibration training.
