To examine the associations of cardiorespiratory fitness with executive function, episodic memory, and global cognition and sex differences in these associations in community-dwelling older adults with amnestic mild cognitive impairment.
A cross-sectional study using baseline data from the aerobic exercise and cognitive training (ACT) trial.
The ACT trial conducted exercise testing in an exercise laboratory and data collections in a research facility.
ACT trial participants were recruited through referrals, registries, exhibits, flyers, media, and advertisements and screened for eligibility. To be eligible for this study, ACT enrollees needed complete data on all study variables. Among 146 ACT enrollees, 142 met eligibility for this study (N=142).
None.
Cardiorespiratory fitness was measured as peak oxygen consumption (Vo) with a peak cycle-ergometer test, executive function with the EXAMINER, episodic memory with the Brief Visuospatial Memory Test-Revised, and global cognition with Montreal Cognitive Assessment.
The average age of the sample was 73.8±5.8 years with 16.9±2.9 years of education, with 87.3% White, 51.4% men, and 69.7% married. After controlling for covariates, Vo was significantly related to executive function (=.037, standard error [SE]=0.015, =.0154, semipartial [] correlation coefficient=.239) and episodic memory (=.590, SE=0.226, .0102, =.216), but not global cognition (=.074, SE=0.055, .1837, =.125). For men, Vo was significantly associated with executive function (=.063, SE=0.024, =.0099, =.430) and episodic memory (=1.088, SE=0.312, =.0009, =.382).
Our findings show that Vo was associated with executive function and episodic memory in the overall sample and in men. Future studies can examine the longitudinal relations between cardiorespiratory fitness and cognition.
探讨社区居住的患有遗忘型轻度认知障碍的老年人中，心肺适能与执行功能、情景记忆和整体认知之间的关联以及这些关联中的性别差异。
一项横断面研究，使用有氧运动与认知训练（ACT）试验的基线数据。
ACT试验在运动实验室进行运动测试，并在研究机构进行数据收集。
ACT试验参与者通过转诊、登记、展览、传单、媒体和广告招募，并进行资格筛选。要符合本研究的条件，ACT参与者需要有所有研究变量的完整数据。在146名ACT参与者中，142名符合本研究的资格（N = 142）。
无。
通过峰值功率计测试以峰值耗氧量（Vo）测量心肺适能，使用EXAMINER评估执行功能，使用修订版简短视觉空间记忆测试评估情景记忆，使用蒙特利尔认知评估量表评估整体认知。
样本的平均年龄为73.8±5.8岁，受教育年限为16.9±2.9年，其中87.3%为白人，51.4%为男性，69.7%已婚。在控制协变量后，Vo与执行功能显著相关（= 0.037，标准误[SE] = 0.015，= 0.0154，半偏[]相关系数 = 0.239）和情景记忆显著相关（= 0.590，SE = 0.226，= 0.0102，= 0.216），但与整体认知无显著相关性（= 0.074，SE = 0.055，= 0.1837，= 0.125）。对于男性，Vo与执行功能显著相关（= 0.063，SE = 0.024，= 0.0099，= 0.430）和情景记忆显著相关（=
