Comparative effects of single-task and dual-task acute moderate-intensity exercise on cortisol and cognitive performance.
Article in Frontiers in psychology, 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
Background: Acute physical exercise elicits neuroendocrine responses that may transiently modulate cognitive performance. While moderate-intensity single-task exercise (e.g., running) has been shown to improve cognition, the acute cognitive and hormonal effects of dual-task exercise, which involves cognitive load, remain underexplored. Objectives: This study aims to compare the effects of moderate-intensity single-task (5-km run) and dual-task (orienteering) exercise on salivary cortisol levels and cognitive performance in healthy young adults. Methods: Twenty-one male college students (age: 20.57 ± 2.57 years) participated in a randomized crossover design. Each participant completed both exercise conditions. Salivary cortisol and cognitive performance (assessed via 2-Back, Mental Rotation, and Bells visual search tests) were measured before and after exercise. Exercise intensity was standardized using VO₂max, and heart rate was continuously monitored. Results: Orienteering elicited a significant increase in salivary cortisol ( Conclusion: Dual-task exercise induced stronger neuroendocrine responses and broader cognitive benefits compared to single-task running. These findings suggest that integrating cognitive demands into exercise routines may enhance acute cortisol-driven facilitation of executive functions, highlighting the importance of such exercises in programs targeting cognitive and brain health.
