弹力带训练对于中老年人动态平衡能力的影响研究

Effects of Elastic-band Resistance Training on Dynamic Balance Ability in Middle-aged And Elderly People

研究目的:探究针对下肢自由度的弹力带抗阻训练对于中老年人动态平衡能力的影响。研究方法:选取16名中老年人作为研究对象,随机将其分为对照组和实验组,每组8人,对实验组进行为期8周的运动干预。运动干预前后,分别测量所有受试者的前后稳定极限指标、Y偏移量、Functional Reach Test(FRT)以及Timed Up and Go test(TUG)指标去评价其动态平衡能力。使用独立样本t检验来分析组间差异,使用配对样本t检验来分析组内差异,检验水准选α=0.05。研究结论:运动干预前后,实验组和对照组受试者组内和组间在前后稳定极限指标和FRT动态平衡指标间的差异具有统计学意义(P<0.05),而在TUG,Y偏移量指标间的差异不具有统计学意义(P>0.05)。针对下肢自由度的弹力带抗阻训练可以改善中老年人的动态平衡能力,但是对于正常步行过程中的动态平衡指标无明显改善。应根据具体的训练目的来选择合适的训练计划。

Research purpose:This study aimed at exploring the impact of elastic band resistance training on the freedom of lower limb for the dynamic balance ability of middle-aged and elderly people.Research Method:Sixteen middle-aged and elderly people were enrolled in this study.They were randomly divided into the control group and the experimental group,with 8 people in each group.The experimental group was given an 8-week exercise intervention.Before and after the exercise intervention,the Limit Of Stability in the anteroposterior direction,the Y offset,the Functional Reach Test(FRT)and Timed Up and Go test(TUG)of all subjects were respectively measured to evaluate its dynamic balance ability.The differences among groups were analyzed by independent-sample t-test,and the differences in groups were analyzed by paired-sample t-test,the test level wasα=0.05.Research Conclusion:Before and after exercise intervention,the difference between the Limit Of Stability in the anteroposterior direction and the FRT in the experimental group and the control group was statistically significant(P<0.05),while in the TUG and Y offset,the difference was not statistically significant(P>0.05).The elastic band resistance training for lower limb freedom can improve the dynamic balance ability of middle-aged and elderly people,but there is no significant improvement in the dynamic balance index during normal walking.The appropriate training program should be based on the specific training purpose.
