Acute and Chronic Effects of Aerobic Exercise on Motor Inhibition and Cortical Excitability in Adolescents With Attention Deficit Hyperactivity Disorder.
Article in Brain and behavior, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionAccumulating evidence suggests that acute aerobic exercise facilitates improvement in motor inhibition among adolescents with attention-deficit hyperactivity disorder (ADHD), potentially through exercise-induced modulation of cortical excitability. The present study aimed to investigate the effects of both acute and chronic aerobic exercise on motor inhibition and cortical excitability, and to elucidate the relationship between these variables in adolescents diagnosed with ADHD.
methodsA partial cross-over experimental design was employed. Twenty-four adolescents with ADHD underwent assessments of motor inhibition and cortical excitability before and after engaging in either acute or chronic aerobic exercise, or a control intervention.
resultsBoth acute and chronic aerobic exercise elicited significant enhancements in motor inhibition, with chronic aerobic exercise demonstrating more pronounced effects. Furthermore, chronic aerobic exercise resulted in a significant reduction in cortical excitability compared to both the control condition and acute aerobic exercise. In addition, the degree of improvement in motor inhibition was positively associated with increased cortical inhibition. DISCUSSION: These findings suggest that the enhancement of motor inhibition following aerobic exercise in adolescents with ADHD may be underpinned by specific neurophysiological mechanisms related to cortical excitability. Particularly, chronic aerobic exercise appears to exert a more robust modulatory effect, highlighting its potential as a therapeutic strategy for improving motor inhibitory function in this population.
