摘要

背景:越来越多的证据表明，不稳定阻力训练(IRT)对个体，健康以及神经系统疾病患者的功能和认知相关益处。然而，IRT是否在老年人的姿势控制中发挥重要作用尚未确定。目的:评价12周IRT对主观认知障碍老年人静态姿势控制的影响。方法:在这项随机对照试验中，共有67名参与者(65岁及以上)被随机分配到12周的IRT (n= 22)，传统阻力训练(RT) (n= 23)或健康教育对照组(n= 22)。静态姿势控制通过力平台进行评估，该力平台记录两足支撑下压力中心(CoP)在前后(AP)和中外侧(ML)方向的位移幅度(30秒)，同时眼睛睁开和闭上。结果:各组在睁眼和闭眼条件下，AP位移均增加。在闭眼状态下，只有IRT组增加了ML位移。在任何姿势对照中，组间差异均无统计学意义(p < 0.05)。结论:12周的IRT并不能改善老年认知障碍患者的静态姿势控制。

Effects of instability resistance training on static postural control of cognitively impaired older adults

BACKGROUND: Mounting evidence has demonstrated functional and cognitive-related benefits after Instability Resistance Training (IRT) in individuals, healthy as wellas patients presenting with neurological disorders. However, whether IRT may play a significant role in the postural control of older adults has not been established. OBJECTIVE: To evaluate the effects of 12- weeks of IRT on static postural control of older adults with subjective cognitive impairment. METHODS: In this randomized controlled trial, a total of 67 participants (aged 65 years and older) were randomly assigned to either 12 weeks of IRT (n= 22), traditional resistance training (RT) (n= 23), or a health education control group (CON) (n= 22). Static postural control was assessed using a force platform that recorded the displacement amplitude of the center of pressure (CoP) in the anteroposterior (AP) and mediolateral (ML) directions in bipedal support (30 seconds) with eyes open and closed. RESULTS: All groups increased AP displacement in the conditions of eyes open and closed. During the eyes-closed condition, only the IRT group increased the ML displacement. No between-group differences were detected in any postural control (p> 0.05). CONCLUSIONS: 12 weeks of IRT does not improve the static postural control in older adults with cognitive impairment.

期刊介绍： Isokinetics and Exercise Science (IES) is an international journal devoted to the study of theoretical and applied aspects of human muscle performance. Since isokinetic dynamometry constitutes the major tool in this area, the journal takes a particular interest in exploring the considerable potential of this technology. IES publishes studies associated with the methodology of muscle performance especially with respect to the issues of reproducibility and validity of testing, description of normal and pathological mechanical parameters which are derivable from muscle testing, applications in basic research topics such as motor learning paradigms and electromyography. The journal also publishes studies on applications in clinical settings and technical aspects of the various measurement systems employed in human muscle performance research. The journal welcomes submissions in the form of research papers, reviews, case studies and technical reports from professionals in the fields of sports medicine, orthopaedic and neurological rehabilitation and exercise physiology.
