The development of voluntary participating program and the effect of its improvement of cognitive function in older population.

背景和目的：参加一般推荐的有氧运动或力量锻炼可能对老年人具有挑战性；因此，有必要考虑适合他们的体育活动的类型和水平，以改善他们的认知和步态功能，并坚持锻炼计划。这促使人们努力确定需要较少体力和频率的运动，同时仍能提供认知和健康益处。在这里，我们的目的是评估一种新的双任务净步运动（NSE）对老年人认知能力和步态功能改善的影响，每周进行一次，连续8周。方法：在测试前/测试后的实验病例对照研究中，从社区居民中招募60名健康老年人（平均年龄76.4岁），随机分为两组。一个双重任务NSE组和一个对照组。NSE组被要求在不踩到网的情况下走过网，否则会被网夹住。在基线和干预8周后进行两种计算机面板型认知功能评估，Touch- m和Touch panel-type Dementia Assessment Scale (TDAS)，以确定NSE的效果。步态功能的改善也通过Timed Up and Go （TUG）测试分数进行评估。采用重复测量的混合效应模型（组x时间）（方差分析，F检验）来检验NSE的效果。协变量包括年龄和性别进行调整（ANCOVA）。结果：NSE组在8周内认知能力（改变6.8%，总Touch-M评分5.4分，p = 0.03）和步态（改变11.5%，TUG时间-0.98秒，p < 0.001）均有显著改善。在对照组中，图1没有明显的改善。结论：双任务NSE能够改善健康老年人的认知能力和步态功能。我们的研究结果表明，NSE提供了与其他体育锻炼项目类似的好处，同时减少了所需的运动强度和频率。因此，NSE是大部分老年人的选择，对他们来说，有氧运动或力量运动可能是不可行的。少

Background and Purpose: Participation in generally recommended aerobics or strength exercises may be challenging for older adults; therefore, it is necessary to consider the types and levels of physical activities suited for them in order to improve their cognitive and gait function and adherence to exercise programs. This has prompted efforts to identify exercises that require less physical strength and frequency of performance, while still offering cognition and health benefits. Here, we aimed to assess the effect of a novel dual-task net-step exercise (NSE) performed once a week for 8 consecutive weeks on improvements in cognitive performance and gait function in an older population.Methods: In this pre-/post-test experimental case control study, 60 healthy elders (mean age 76.4 years) were recruited from community-dwelling people and separated randomly into two groups.a dual-task NSE group and a control group. The NSE group was asked to walk across the net without stepping on the r … More opes or getting caught in the net. Two computer panel-type cognitive functional assessments, Touch-M and Touch Panel-type Dementia Assessment Scale (TDAS), were administered at baseline and following 8 weeks of intervention, to determine the effects of NSE. Improvements in gait function were also evaluated using Timed Up and Go (TUG) test scores. Mixed-effect models with repeated measures (group x time) (analysis of variance, F test) were used to test the effects of NSE. Covariates including age and sex were adjusted (ANCOVA).Results: The NSE group showed significant improvement in cognitive performance (6.8% change; total Touch-M score 5.4 points; p = 0.03) and gait performance (11.5% change; TUG time -0.98 sec; p < 0.001) over the 8-week period. In the control group, there was Figure 1no significant improvement.Conclusion: This study shows that dual-task NSE is capable of improving cognitive performance and gait function in healthy old people. Our results indicate that NSE offers similar benefits as other physical exercise programs while reducing the intensity and frequency of exercise required. Accordingly, NSE is an option for a large segment of the older population for whom aerobics or strength exercises may not be feasible. Less
