abstract="PURPOSE: We investigated the relationship between aerobic fitness and sustained attention capacity by comparing task performance and brain function, by means of event-related potentials (ERPs), in high- and low-fit young adults. <br><br>METHODS: Two groups of participants (22 higher-fit and 20 lower-fit) completed a 60' version of the Psychomotor Vigilance Task (PVT). Behavioral (i.e., reaction time; RT) and electrophysiological ERP (i.e., contingent negative variation; CNV; and, P3) were obtained and analyzed as a function of time-on-task. A submaximal cardiorespiratory fitness test confirmed the between-groups difference in terms of aerobic fitness. <br><br>RESULTS: The results revealed shorter RT in higher-fit than in lower-fit participants in the first 36' of the task. This was accompanied by larger CNV amplitude in the same period of the task in higher-fit than in lower-fit group. Crucially, higher-fit participants maintained larger P3 amplitude throughout the task compared to lower-fit, who showed a reduction in the P3 magnitude over time. <br><br>CONCLUSION: Higher fitness was related to neuroelectric activity suggestive of better overall sustained attention demonstrating a better ability to allocate attentional resources over time. Moreover, higher fitness was related to enhanced response preparation in the first part of the task. Taken together, the current dataset demonstrated a positive association between aerobic fitness, sustained attention, and response preparation.<p /> <p>Language: en</p>",
