核心不稳定力量训练对老年人躯干肌力和脊柱活动性的影响

The effect of core unstable strength training on trunk muscle strength and spine mobility in the elderly

目的 :探讨核心不稳定力量训练对老年人躯干肌力和脊柱活动性的影响。方法 :将32名老年人分为干预组和对照组。干预组有16名,其中男性8名,女性8名,平均年龄(70.8±4.1)岁。干预组有16名,其中男性7名,女性9名,平均年龄(70.2±4.5)岁。干预组的老人参与9周核心不稳定力量训练,对照组的老人参加9周常规日常活动。评估两组老人干预前后躯干屈肌、伸肌、侧屈肌(右、左)、旋转肌(右、左)的最大等距强度以及矢状面和冠状面脊柱活动角度。结果 :干预后,干预组躯干屈肌、伸肌、侧屈肌和旋转肌力量均有明显提高,差异有统计学意义(P<0.01),矢状面和冠状面方向的脊柱活动度有明显提高,差异有统计学意义(P <0.05)。结论 :核心不稳定力量训练是一种可行的老年人运动方案,可改善与年龄相关的躯干肌力和脊柱活动角度,可以作为传统平衡和阻力训练的辅助或替代。

Objective:To investigate the effect of core unstable strength training on trunk muscle strength and spinal mobility in the elderly.Methods:Thirty-two elderly patients were divided into an intervention group and a control group.The intervention group had 16 cases,and among them,there were 8 males and 8 females,with the average age of(70.8±4.1)years.The control group had 16 cases and among them there were 7 males and 9 females,with the average age of(70.2±4.5)years.The elderly in the intervention group participated in 9 weeks of core unstable strength training,while the elderly in the control group participated in 9 weeks of routine daily activities.The maximum isometric strength of trunk flexors,extensors,lateral flexors(right and left),rotators(right and left)and the angles of movement of the sagittal and coronal spine were evaluated in the elderly in the two groups before and after intervention.Results:After the intervention,the strength of trunk flexors,extensors,lateral flexors and rotators in the intervention group was significantly improved,and the difference was statistically significant(P<0.01),the range of motion of the spine in the sagittal and coronal planes was significantly improved,and the difference was statistically significant(P<0.05).Conclusion:Core unstable strength training is a feasible exercise program for the elderly,which can improve age-related trunk muscle strength and spine angle of motion,and can be used as a supplement or substitute for traditional balance and resistance training.
