Compelling evidence supports an association between the attribute of aerobic fitness and achievement scores on standardized tests of reading. However, such standardized assessments provide only a broad valuation of a complex network of language related sub-processes that contribute to reading and are heavily confounded by other attention-related processes. The present investigation sought to clarify the nature of the association between aerobic fitness and language processing in a sample of college-aged adults. Participants were bifurcated based on aerobic fitness level and on a separate day were asked to complete a lexical decision task while neuroelectric activity was recorded. Analysis of word-level language-related ERP components revealed no fitness differences. However, lower aerobically-fit individuals elicited smaller amplitude for attention-related ERP components relative to the higher aerobically-fit group. These data provide initial evidence to suggest that fitness-related differences in reading achievement may result from attentional processes rather than acting upon specific language-related processes.

有氧健身与差异注意有关，但与语言相关的认知过程无关

令人信服的证据支持有氧健身属性与标准化阅读测试成绩之间存在关联。然而，此类标准化评估仅提供对有助于阅读的语言相关子过程的复杂网络的广泛评估，并且被其他与注意力相关的过程严重混淆。本调查旨在阐明有氧健身与语言处理之间的关联的性质，在一个大学生样本中。参与者根据有氧健康水平分为两部分，并在另一天被要求完成词汇决策任务，同时记录神经电活动。对单词级语言相关 ERP 组件的分析显示没有适应度差异。然而，相对于有氧健康水平较高的人群，有氧健康水平较低的个体引起与注意力相关的 ERP 成分的幅度较小。这些数据提供了初步证据，表明与健康相关的阅读成绩差异可能源于注意力过程，而不是作用于特定的语言相关过程。
