本研究的目的是确定运动练习在单任务和双任务条件下对老年人认知和运动表现的影响。14名年轻人（19 - 28岁）和12名老年人（67 - 75岁）在单任务和双任务条件下进行了精确握力正弦波力跟踪和工作记忆任务。参与者进行了预测试、100次运动练习试验和后测试。在力跟踪和认知任务中，年轻人的表现优于老年人。运动练习在单任务和双任务条件下都改善了两组的力跟踪情况。然而，当老年人从单任务转换到双任务条件时，练习并没有阻止其运动表现的下降。经过练习，老年人在双任务条件下的认知表现有所提高。年龄的增长似乎与管理和协调多项任务的能力下降有关，这种情况在长时间练习后仍然存在。
aim of this study was to determine the effects of motor practice on cognitive and motor performance in older adults under single- and dual-task conditions. Fourteen younger (19-28 years) and 12 older adults (67-75 years) performed a precision grip sine wave force-tracking and a working memory task under single- and dual-task conditions. Participants performed a pretest, 100 motor practice trials, and a post-test. In the force-tracking and cognitive task, young outperformed older adults. Motor practice improved force-tracking under single- and dual-task conditions for both groups. However, practice did not prevent a decline in motor performance for older adults when they moved from single- to dual-task conditions. After practice, older adults improved cognitive performance in dual-task conditions. Advances in age appear to be associated with a decrease in the ability to manage and coordinate multiple tasks, which remains after extended practice.
