目的 探讨渐进式核心肌力训练对老年人平衡功能的影响。 方法 2018年4月至9月，80例社区老年人分别接受自由操训练(对照组, n = 40)和核心肌力训练(干预组, n = 40)12周。训练前后测量单脚闭眼站立时间、闭眼30 s安静站立压力中心移动轨迹长、最大前后倾压力中心距离、计时起立行走测试(TUGT)和30 s连续站立坐下次数。 结果 训练后，两组单脚闭眼站立时间、闭眼30 s安静站立压力中心移动轨迹长、最大前后倾压力中心距离、TUGT和30 s连续站立坐下次数均显著改善(t > 6.446, P < 0.001)，干预组优于对照组(t > 2.127, P < 0.05)。 结论 渐进式核心肌力训练能够改善老年人的动态与静态平衡能力、身体控制能力及核心部位力量，能有效预防老年人跌倒的发生。
Objective To explore the effect of progressive core strength training on balance of the old adults. Methods From April to September, 2018, 80 old persons were divided into control group (n = 40) and intervention group (n = 40), who accepted physical exercise and core strength training, respectively, for twelve weeks. They were assessed with one-legged standing time with eyes closed, center?of?pressure (COP) track as standing with eyes closed in 30 seconds, maximum distance of COP tilting, Timed "Up and Go" Test (TUGT) and standing up and sitting down in 30 seconds. Results The one-legged standing time with eyes closed, COP track as standing with eyes closed in 30 seconds, maximum distance of COP tilting, TUGT and standing up and sitting down in 30 seconds improved after training (t > 6.446, P < 0.001), and they improved more in the intervention group than in the control group (t > 2.127, P < 0.05). Conclusion Progressive core strength training can improve the dynamic and static balance, body control and core strength for the old adults, which may prevent them from falling down.
