With the growing trend toward engagement in sedentary behaviors during childhood, a greater understanding of the relationship between cardiorespiratory fitness and cognition during development is of increasing importance.
The aim of this investigation was to assess the extent to which failures in sustained attention may underlie deficits in cognition associated with poorer aerobic fitness.
A sample of 62 preadolescent children between the ages of 9 and 10 years were separated into higher- and lower-fit groups according to their cardiorespiratory fitness.
Findings indicated that lower-fit children exhibited poorer overall response accuracy during a task requiring aspects of cognitive control relative to their higher-fit counterparts, with a disproportionately greater number of errors of omission, and longer, more frequent sequential errors of omission.
These findings suggest that poorer vigilance may contribute to deficits in cognitive control associated with poorer aerobic fitness.
随着儿童久坐行为趋势的增长，越来越需要深入了解心肺适能与发育过程中的认知之间的关系。
本研究旨在评估持续性注意力缺陷是否是与较差的有氧适能相关的认知缺陷的基础。
根据心肺适能，将 62 名 9 至 10 岁的青春期前儿童分为高适能组和低适能组。
研究结果表明，低适能儿童在需要认知控制的任务中的整体反应准确性较差，与高适能儿童相比，错误遗漏的比例更大，遗漏的顺序错误也更长、更频繁。
这些发现表明，较差的警觉性可能导致与较差的有氧适能相关的认知控制缺陷。
