Effect of vigorous-intensity exercise on the working memory and inhibitory control among children with attention deficit hyperactivity disorder: a systematic review and meta-analysis.

Abstract

This study primarily evaluated the effects of vigorous-intensity exercises on working memory and inhibitory control in children with attention deficit hyperactivity disorder (ADHD). Search for eligible studies through four databases, and then proceed with screening. The inclusion criteria are as follows: (1) Children with ADHD; (2) Randomised controlled trial; (3) The intervention group received exercise, while the control group did not perform any exercises as the treatment; (4) Conducted pre- and post-exercise assessments, which include working memory and inhibitory control parameters. Use the Cochrane bias risk assessment tool to evaluate the quality of the selected study. Select standardized mean difference as the appropriate effect scale index, and use Revman 5.4 software to analyze the mean difference. This study was registered in the PROSPERO (CRD42024597510). A total of ten studies fulfilled the inclusion criteria and were selected for the meta-analysis. The included studies involved 367 males and 159 females, where 273 belonged to the exercise group and 253 from the control group. Participants in the exercise group enhanced working memory [0.37 (0.12, 0.63) p < 0.05, I² = 0%] than the control group. In addition, the results indicated that submaximal intensity exercise improved inhibition regulation levels significantly [- 0.34 (- 0.65, - 0.03), p < 0.05, I² = 0%]. Based on the systematic meta-analysis results, vigorous-intensity exercises have effective working memory, cognitive function, and motor ability-increasing effects on children with ADHD. Furthermore, Submaximal intensity exercise can effectively improve control inhibition in children with ADHD.
