Why the study?
Studies examining electrocortical activity changes using stationary cycling have shown mixed findings, with some reporting increases and others decreases in post-exercise brain activity.
Does a graded exercise test to volitional exhaustion alter electrocortical activity in healthy untrained subjects?
Population
16 healthy, untrained subjects (8 males; 8 females)
Comparison
Continuous EEG immediately following vs before a graded exercise test
Follow-up
Immediately following the graded exercise test

Post-exercise theta increases may signal central fatigue; hypothesis-generating for EEG monitoring of volitional exhaustion.
Does a graded exercise test to volitional exhaustion alter electrocortical activity in healthy untrained subjects?
Exercise to volitional exhaustion increases theta power in prefrontal and motor cortices, suggesting a role for central fatigue.
