Effect of Game-based HIIT Program on the Executive Function of Children With ADHD

Summary

Background: Attention-deficit/hyperactivity disorder (ADHD) is a common developmental disorder in childhood, with a 5%-6% worldwide prevalence. Children with ADHD often demonstrate impaired executive function, which is closely related to the development of the commonly observed behavioral problems such as inattention, impaired inhibition, and hyperactivity. The purpose of this study is to examine whether a game-based high-intensity interval training (HIIT) program can improve the executive function of children with ADHD, compared with a traditional structured aerobic exercise program and a non-treatment control group.

Methods/design: A total of 42 children with ADHD will be recruited to participate in this three-arm school-based randomized controlled trial. An 8-week specially designed game-based HIIT (GameHIIT) program and a traditional game-based structured aerobic exercise (GameSAE) program will be delivered to those children randomly assigned to these two intervention groups, while the children in the control group will maintain their regular physical activity over the same period. A number of outcome measures including executive function, cerebral hemodynamic response, physical activity, physical fitness, and enjoyment and adherence to the intervention will be assessed for both groups at baseline (T0), immediately after the intervention period (T1), and after the follow-up period (T2).

Discussion: HIIT has recently emerged as a feasible and efficacious strategy for increasing physical health outcomes and cognitive function, including executive function, in healthy young people. However, research has yet to investigate whether the executive function of children with ADHD can be effectively enhanced through HIIT. If, as hypothesized, GameHIIT program improves outcomes for children with ADHD, the present research will inform the development of targeted exercise programs that can be more broadly used with this particular population.

Interventions

OTHER

Game-based High-Intensity Interval Training

There will be two training sessions each week. In each training session, there will be four sets of training programs separated by 3 minutes of passive recovery in accordance with a previous study.Each set of activities will last for around 5 minutes; therefore, the total duration of each training session will be approximately 30 minutes. A small group size (4-6 children per group) will be adopted to facilitate individual supervision and adaption of the exercise program.

OTHER

GameSAE

Similar to GameHIIT, the intervention will comprise 8 weeks of structured aerobic exercise sessions, lasting one hour on average in each session and up to twice per week. Six to eight stations of multidimensional exercises will be set up for each session. Adopting the train-the-trainer (TTT) model, training will be provided by front-line healthcare providers or trained helpers. Children will be instructed to finish the exercises in all stations one after another in a predetermined order.
