The Effect of an Acute Aerobic Exercise with Different Intensities on the Executive Functions of 9-10-year-old Children.

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: It is well-established that executive function can be affected by a session of aerobic training. Our study aimed to determine how acute aerobic exercise affect executive function at different intensities in 9-10-year-old children. Methods: The participants in this quasi-experimental study were 36 children (9.58 years±0.50) in Saqqez, Kurdistan Province, Iran in the first half of 2022. They were randomly assigned into 60% and 80% heart rate reserve (HRR) and a control group. All groups performed the Progressive Aerobic Cardiovascular Run (PACER) test in the first stage of study to ensure homogeneity. Then, in the pretest- posttest design, inhibitory control and working memory were assessed using the Stroop and N-back tests. During the 15-minute exercise session, participants exercised on a treadmill at different intensities of 60% and 80% of their HRR. One-way Analysis of Variance (ANOVA) and paired t-test were employed to analyze between-group and within-group differences in control and intervention groups. Results: According to the results, working memory scores of children improved significantly in 60% and 80% HRR groups (65.44±9.51 vs. 44.69±17.76) compared with the control group (31.00±2.02) (P<0.0001). Different exercise intensities; however, did not show any advantage over a control group in the interference score of correct answers, or reaction time (RT) of inhibition control (60% HRR: 4.08±3.77, 80% HRR: 1.16±3.32, Control: 4.25±3.62, P=0.074), (60% HRR: 52.00±65.91, 80% HRR: 85.66±59.75, Control: 27.16±106.46, P=0.215). Conclusions: The study findings revealed that working memory in pre-adolescents can be improved by a 15-minute session of moderate or high-intensity aerobic exercise. However, there were no significant differences between the groups in terms of inhibitory control.
