Moderate and vigorous aerobic exercise enhances inhibitory control, but not working memory or cognitive flexibility, up to the second ventilatory threshold: a randomized crossover trial.

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
introductionThe effects of acute physical exercise on executive functions remain controversial, partly due to inconsistencies in how exercise intensity is measured. This study investigated the impact of moderate and vigorous aerobic exercise on three core components of executive function: inhibitory control, working memory, and cognitive flexibility. Exercise intensity was rigorously defined using a combination of heart rate reserve, ventilatory thresholds, and rate of perceived exertion.
methodTwenty-six physically active adults completed three separate sessions in a randomized order: Rest (REST), Moderate-intensity exercise (MOD), and Vigorous-Intensity exercise (VIG). Cognitive performance was assessed during each condition using the Go/No-Go test (inhibitory control), the 2-back test (working memory), and the Multitasking test (cognitive flexibility).
resultsInhibitory control improved significantly during exercise. Response Times (RT) on the Go/No-Go test were reduced in both MOD (p = 0.038) and VIG (p = 0.003) compared with REST, without changes in accuracy. In contrast, working memory and cognitive flexibility showed no significant differences across conditions.
conclusionsAcute moderate and vigorous aerobic exercise, up to the second ventilatory threshold, selectively enhances inhibitory control by reducing RT, with no detectable effects on working memory or cognitive flexibility. By integrating multiple physiological and perceptual markers of intensity, this study provides a rigorous evaluation of the acute cognitive effects of aerobic exercise.
