Emerging evidence suggests that multicomponent exercise provides greater benefits for physical and cognitive function than single component exercise. However, few studies have been conducted to determine these effects in older adults with mild cognitive impairment (MCI) and findings have been less conclusive. It has been reported that older women have a greater risk of falls and a higher incidence of dementia than men.
To examine the effects of multicomponent exercise on cognitive performance and fall risk in older women with MCI.
An experimental design comparing the exercise and control groups.
Forty community-dwelling older women with MCI were allocated to the exercise (n = 20) and control (n = 20) groups.
Twelve weeks of multicomponent exercise program (aerobic, resistance, and balance exercise) 60 mins/day, 3 days/week.
Cognitive performance including the Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog) and Trail Making Test (TMT) and fall risk including the Timed Up and Go (TUG) single-, dual-task, and Physiological Profile Assessment (PPA) were administered before and after the 12-week exercise program.
At the end of the 12-week training, participants in the exercise group had a significantly greater improvement in TMT part A (p < 0.05), TUG dual-task (p < 0.05), and PPA composite score (p < 0.05) when compared to the control group. The exercise group also demonstrated significant improvement in TUG dual-task, PPA composite score, PPA subcomponents including postural sway and reaction time when compared to baseline (p < 0.05). In contrast, at 12-week, the control group showed a decline in TUG dual-task performance as compared to baseline (p < 0.05).
The 12-week multicomponent exercise improved attention, dual-task ability, and reduced risk of falling in older women with mild cognitive impairment.
新出现的证据表明，多组分运动比单组分运动对身体和认知功能有更大益处。然而，很少有研究确定这些影响在轻度认知障碍（MCI）的老年人中的情况，且研究结果不太具有结论性。据报道，老年女性比男性有更高的跌倒风险和痴呆发病率。
研究多组分运动对患有MCI的老年女性认知表现和跌倒风险的影响。
比较运动组和对照组的实验设计。
40名居住在社区的患有MCI的老年女性被分配到运动组（n = 20）和对照组（n = 20）。
为期12周的多组分运动计划（有氧运动、抗阻运动和平衡运动），每天60分钟，每周3天。
在为期12周的运动计划前后，进行认知表现测量，包括阿尔茨海默病评估量表-认知子量表（ADAS-Cog）和连线测验（TMT），以及跌倒风险测量，包括计时起立行走测试（TUG）单任务、双任务和生理特征评估（PPA）。
在为期12周的训练结束时，与对照组相比，运动组参与者在TMT A部分（p < 0.05）、TUG双任务（p < 0.05）和PPA综合评分（p < 0.05）方面有显著更大的改善。与基线相比，运动组在TUG双任务、PPA综合评分、包括姿势摆动和反应时间的PPA子成分方面也有显著改善（p < 0.05）。相比之下，在12周时，对照组与基线相比TUG双任务表现下降（p < 0.05）。
为期12周的多组分运动改善了患有轻度认知障碍的老年女性的注意力、双任务能力，并降低了跌倒风险。
