本研究评估了老年人心血管健康与时间准备之间的关系。110名老年人（年龄60-69岁或70-79岁）根据步行测试估计的有氧健身水平分为低健身组和高健身组。反应准备过程进行了评估与反应时间任务，其中短（1，3，5秒）和长（5，7，9秒）的准备间隔随机变化。结果表明，高适应个体随着时间的推移（长达9秒）保持准备的能力更好。本研究的结果表明，在老年人中，高水平的有氧健身与更有效的反应准备过程。
This study assessed the relationship between cardiovascular fitness and temporal preparation in elderly persons. 110 older adults (aged 60-69 or 70-79 years) were sorted into low- and high-fit groups based on aerobic fitness level estimated with a walking test. Response preparation processes were assessed with reaction time tasks in which short (1, 3, 5 s) and long (5, 7, 9 s) preparatory intervals varied randomly. The results suggest a better ability in high-fit individuals to maintain preparation over time (up to 9 s). Results of the present study suggest that in older adults, a high level of aerobic fitness is associated with more efficient response preparation processes.
