Breaking barriers: challenging the notion of a strong link between physical fitness and executive functions in 10-year-olds.
Article in BMC pediatrics, 2025. 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
backgroundThis study utilized a replicated measurement approach to comprehensively explore the connections between various aspects of physical fitness and executive functions in prepubescent children.
methodsThe sample consisted of 62 students (32 boys, 30 girls, aged 10.44 ± 0.33 years) with assessments of physical fitness and executive functions conducted at two time points 4 months apart. Physical fitness assessment involved evaluating body composition (body-mass index, fat mass, fat-free mass) and measures of motor coordination (Obstacle Course Backward test), strength (Long Standing Jump test), speed of movement (Plate Tapping test), and aerobic fitness (20 m Shuttle Run test). Executive functions, specifically inhibition and cognitive flexibility, were evaluated using the Modified Stroop task and Trail Making task, respectively.
resultsInitial measurements showed only low correlations (r = 0.12-0.20) between the Plate Tapping and Shuttle Run with executive function tasks, which did not reach statistical significance, while other connections were consistently trivial. In the follow-up measurement, the Plate Tapping test showed a moderate correlation (r = 0.39) with the Stroop task, while remaining correlations were either negligible or low and not significant. The findings suggest two important conclusions: (i) body composition shows limited association with executive functions in children; (ii) among motor variables, only the speed of limb movement may have some relevance for inhibition, but this association is relatively modest and inconsistent.
conclusionsOverall, the morphological status and motor competence of prepubertal children seem to have minimal effects on cognitive tasks involving inhibition and cognitive flexibility, and vice versa.
