Acute Exercise Fatigue Impairs Cognitive Control: Neurophysiological Mechanisms Revealed by ERP and ERSP Analyses.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This study aimed to investigate the effects of acute exhaustion exercise on cognitive control in young men, a key higher cognitive function for goal-directed behavior. Although long-term regular exercise benefits cognition, the effects of acute exhaustion exercise on cognitive control and its neural mechanisms are not fully understood. 35 male college students completed a Stroop task before and after exhaustion exercise on a cycle ergometer with incremental load. Electroencephalogram data were collected synchronously during the task. Behavioral measures (accuracy, reaction time), Event-Related Potential components (N2, P3 amplitudes and latencies), and Event-Related Spectral Perturbation (energy changes in theta, alpha, beta frequency bands) were analyzed. Results: Behavioral results showed that task accuracy only significantly decreased under the conflict condition (incongruent trials) following exhaustive exercise. ERP analysis revealed that the P3 amplitude at the anterior site (Fz) was significantly reduced post-exercise, but specifically for the incongruent condition, while the N2 amplitude demonstrated a more widespread enhancement. Time-frequency analysis found a significant decrease in alpha-band power over the parietal region after exercise. Theta and beta band activities were not significantly affected by exercise-induced fatigue. Conclusions: Acute exhaustive exercise did not impair early conflict monitoring functions (as indicated by stable N2 component and theta oscillations), but it compromised later higher-order cognitive processes related to attentional resource allocation and conflict resolution (manifested as reduced anterior P3 amplitude), accompanied by decreased efficiency in neural oscillatory activity associated with inhibitory control (reduced alpha power). This suggests that fatigue primarily affects the neural mechanisms of the "implementation" stage rather than the "monitoring" stage in the cognitive control cascade.
