Exercise has been shown to benefit our physical and mental health. Some studies have suggested that it can also potentially help with ADHD.
This study wanted to further examine the effects of exercise on executive function.
Executive function refers to the higher-level thought processes in our brains. These include planning, working memory, and inhibition.
Studies have shown that ADHD negatively affects working memory:
This study examined the effects of an exercise program on executive function tests in children.
Acute physical activity of moderate to vigorous intensity has been shown to improve cognitive functions in children. However, the empirical evidence associated with Attention Deficit Hyperactivity Disorder (ADHD) in children is still limited, in particular regarding which specific cognit...
The study randomly assigned some children to receive an exercise program and compared them to children who did not receive an exercise program.
After the program, they were tested on their inhibition, task switching, and visual working memory.
Forty-six children (8–12 years old; 82.6% boys) were randomly assigned to either 15 minutes of acute exergaming (physical activity of moderate intensity) or to a control condition (sedentary). Executive function performance in inhibition, switching and visual working memory were assessed...
The results showed that children who received the exercise program had much better reaction times on tests of executive function. They were faster at inhibiting themselves when needed and switching tasks.
However, there were no improvements seen in task accuracy or visual working memory.
Essentially, the children who received the exercise program were faster at completing tasks but were not significantly more or less accurate than those who did not receive the exercise program.
The results revealed that participants in the exergaming group performed significantly faster than those in the control group in terms of both inhibition and switching, but there was no significant difference in the accuracy of the two tasks nor in visual working memory performance.
Based on these results, the authors concluded that exercise may improve certain aspects of executive function in children with ADHD. Unlike medication, exercise is universally healthy and beneficial. It can also be added to any therapy regimen.
These results are consistent with other studies that have shown the benefits of exercise for those with ADHD. While this study did not find a difference in visual working memory, another study was able to detect improvements in working memory with exercise:
These findings suggest that acute physical activity utilizing exergaming has the potential to improve specific aspects of executive functions (reaction times in inhibition and switching) in children with ADHD.
