The relation of aerobic fitness to task preparation was examined in a sample of young adults
separated into higher‐and lower‐fit groups according to their maximal oxygen consumption.
Participants performed a modified Sternberg working memory task under speed and
accuracy instructions while measures of task performance and contingent negative variation
(CNV) were collected. Analyses revealed no significant fitness differences between groups
on task performance measures. However, frontal CNV amplitude was significantly larger for …
