12周惯性哑铃练习对轻度认知损害老年人的干预效果

Intervention Effects of 12-week Momentum-based Dumbbell Exercise on Older Adults with Mild Cognitive Impairment

摘要

摘要:
目的观察12周惯性哑铃练习对轻度认知损害(MCI)老年人认知功能、身体活动能力、生活质量和睡眠质量的影响，并探讨认知改善与其他功能改变之间的关系。
方法将45名MCI老年人随机分为干预组(n=22)和对照组(n=23)。干预组受试者进行惯性哑铃练习(3次/周，60 min/次，持续12周)，对照组不进行运动干预。
结果 12周后，干预组受试者阿尔茨海默病评定量表-认知部分(ADAS-Cog)总分/指令得分、蒙特利尔认知评估量表(MoCA)评分、起立行走计时(TUG)和SF-36健康调查问卷(SF-36)心理总得分均显著改善(均P < 0.05)。与对照组相比，干预组受试者ADAS-Cog总分/单词回忆得分/注意力得分、简明精神量表(MMSE)评分、TUG和匹兹堡睡眠指数(PSQI)的改善程度均具有显著差异(P < 0.05或P=0.05)。偏相关分析结果显示，SF-36心理总得分改变(r=-0.712)、PSQI改变(r=-0.380)与认知改善程度均呈显著负相关。
结论 12周惯性哑铃练习可显著提高MCI老年人的认知功能，并对其移动能力、生活质量和睡眠质量具有积极影响，且心理和睡眠改变程度可能影响认知功能的改善效果。

Abstract:
Objectives To examine the effects of 12-week momentum-based dumbbell training on cognitive function, physical function, quality of life and sleep quality on older adults with mild cognitive impairment (MCI), and to explore the relationship among these changes.
Methods Forty-five community-dwelling older adults with MCI were randomly assigned to either a dumbbell training group(DTG, n=22) or a control group (CG, n=23). Participants in the DTG participated in exercise sessions 3 times weekly for 12 weeks.
Results There were significant within-group changes(improvement) in ADAS-Cog total score, instruction, MoCA and SF-36 Mental Component Summary(P < 0.05).Compared to CG, participants in the DTG significantly improved in ADAS-Cog total score, word recall and attention, MMSE, TUG and PSQI(P ≤ 0.05). And the changes in SF- 36 MCS(r=-0.712) and PSQI(r=-0.380) were significantly correlated with the changes in cognitive function.
Methods A 12-week momentum-based dumbbell training is effective for improving cognitive functions and has potential benefits for improving the physical function in older adults with MCI. These pre-post changes (mental and sleep condition) may influence the degree of cognitive benefits induced by training.
