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

背景和目的：参加普遍推荐的有氧运动或力量练习对老年人来说可能具有挑战性;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以及对锻炼计划的坚持。这促使人们努力确定需要较少体力和表现频率的运动，同时仍然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）每周进行一次，连续8周，对老年人群认知能力和步态功能改善的影响。方法：在这个前/后测试实验性病例对照研究中，60名健康长者（平均年龄76.4岁）从社区居民中招募，并随机分为两组。双任务NSE组和对照组。NSE组被要求在不踩到网的情况下走过网。 ...更多信息 或者被网抓住。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和触摸面板型痴呆评估量表（TDAS），以确定NSE的影响。步态功能的改善也使用定时起身和行走（TUG）测试评分进行评价。采用重复测量混合效应模型（组×时间）（方差分析，F检验）检验NSE的作用。结果：NSE组在8周内表现出认知能力（6.8%变化;总Touch-M评分5.4分; p = 0.03）和步态能力（11.5%变化; TUG时间-0.98秒; p < 0.001）的显著改善。结论：双任务NSE训练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提供了类似的好处，其他体育锻炼计划，同时减少所需的运动强度和频率。因此，NSE是一个选择，为大部分老年人的有氧运动或力量练习可能是不可行的。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
