The purpose of the study was to investigate the association between baseline cognitive function and improvement in mobility after 12 weeks of resistance training (3 times/week; 3 sets, 6-8 repetitions at 75-80% of the 1-repetition maximum) among community-dwelling older adults in Iceland (N=205, 73.5±5.7 years, 57.0% female). Body composition, physical activity status, cardiovascular risk factors, 6-minute walk test (6MWT), and Mini-Mental State Examination (MMSE) were measured. The linear regression model was used to examine the association between baseline MMSE and mobility improvement. Mean distance of 6MWT was 462.8±71.6 meter at baseline and mean change after the exercise intervention was 33.7±34.9 meter. The mean MMSE score at baseline was 27.6±1.9. After adjusting for baseline covariates, we found that baseline MMSE score was significantly associated with improvement in mobility among older adults after the exercise intervention. Cognitive function strongly influences the effect of exercise intervention on mobility among older adults.

认知功能对居住在社区中的老年人流动性改善的影响：一项为期12周的抵抗运动干预研究。

该研究的目的是研究抵抗训练12周后（3次/周； 3组，以1次重复的最大值的75-80％重复6-8次），基线认知功能与运动能力改善之间的关联。冰岛居住在社区中的老年人（N = 205，73.5±5.7岁，女性57.0％）。测量了身体成分，身体活动状态，心血管危险因素，6分钟步行测试（6MWT）和小精神状态检查（MMSE）。线性回归模型用于检验基线MMSE与流动性改善之间的关联。基线时6MWT的平均距离为462.8±71.6米，运动干预后的平均变化为33.7±34.9米。基线时的MMSE平均得分为27.6±1.9。调整基线协变量后，我们发现运动干预后，基线MMSE评分与老年人活动能力的改善显着相关。认知功能强烈影响运动干预对老年人活动能力的影响。
