Abstract

Background and aims: The present study aimed to examine the effect of an acute bout of circuit-base exercise on executive function, visual perception and sleep parameters in neurodiverse children.

Methods: After familiarisation, 34 children (4 female) with ADHD and/or ASD completed two trials (30-min circuit-based exercise (E) or a rested control (C) trial) in a randomised, counterbalanced, crossover design. Participants completed cognitive function tests (Stroop test, Sternberg Paradigm and Visual Search Test) at baseline, immediately post-exercise, and the morning after exercise. Participants were provided with a wrist actigraph to wear overnight to determine sleep duration, wake after sleep onset, sleep efficiency, and sleep latency. Statistical analyses were conducted via ANCOVA, with diagnosis included as a covariate.

Results: Accuracy on the Stroop test (complex level) was better maintained following circuit-based exercise when compared with rest immediately post-exercise (E: 1.88% decreased accuracy; C: 4.73% decreased accuracy, p = 0.009), and on day two (E: 1.22% increased accuracy; C: 6.37% decreased accuracy; p < 0.001). Accuracy on the Sternberg Paradigm (5-item level) was improved immediately post-exercise on the exercise trial when compared with rest (E: 0.37% decreased accuracy; C: 7.29% decreased accuracy; p = 0.011). Improvements in accuracy across both tests were at the expense of response time, which was slower on the exercise trial (all p < 0.05). Sleep parameters did not differ across trials (all p > 0.05).

Conclusion: Moderate intensity circuit-based exercise is an ecologically valid exercise modality that, acutely, improves executive function (compared to rest), which may alleviate the impaired executive function in children with ADHD and ASD.
