Acute moderate-intensity aerobic exercise facilitates processing speed involving inhibitory control but not neuroelectric index of control process and cognitive integration
Bibliographic record
Abstract
Acute aerobic exercise has a facilitative effect on task components with varied inhibitory control demands. However, the effects on specific neural processes evoked by an inhibitory control task remain underexplored. In this study, we examined the effects of acute aerobic exercise on midfrontal theta event-related synchronisation and frontal alpha event-related desynchronisation, two EEG frequency markers that index distinct neural process during inhibitory control. Fifty-eight college-age students (mean age = 19.2 ± 1.0 years old) participated in this within-subjects, crossover, pretest-posttest design study. Participants engaged in a 20-minute bout of aerobic exercise condition and an active control condition on separate days in a counterbalanced order. The aerobic exercise condition consisted of walking/jogging on a treadmill at moderate intensity (approximately 70% of age-predicted maximum heart rate). The active control condition consisted of walking on the treadmill at 0.5 mph and 0% grade. Before and after both conditions, participants completed a flanker task, with concurrent EEG data collection. Despite shorter reaction times following aerobic exercise relative to following active control condition, neither aerobic exercise nor active control condition modulated midfrontal theta event-related synchronisation (which indexes control and behavioural monitoring process) or frontal alpha event-related desynchronisation (which reflects cognitive integration mechanism). Collectively, while acute aerobic exercise enhances inhibitory control performance at a behavioural level, these effects do not extend to the modulation of neural processes underlying behaviour adaptation and cognitive integration mechanisms.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
