Classroom Breaks, Cognition, and Fitness in Elementary School Children

This study is looking at how different types of 10-minute classroom breaks affect thinking skills (executive function) in healthy children aged 8 to 12. We are comparing four types of breaks given twice a day for 12 weeks: a combination of mindfulness and high-intensity interval training (MF-HIIT), mindfulness only (MF-only), high-intensity interval training only (HIIT-only), and sedentary (sitting) activities. We want to see if MF-HIIT has a greater positive effect on how quickly and accurately children can think and process information compared to the other breaks. To join, children must be 8-12 years old, have an IQ of 70 or higher, and be able to exercise. The study aims to enroll 352 participants.

Study design
This is an interventional, randomized controlled trial aiming to enroll 352 healthy children. Participants will be assigned to one of four different 12-week classroom break programs.
What's involved
Participants will take part in a 12-week intervention period, with assessments done before the intervention starts and after it ends.
Compensation
Not stated in the trial record.
Follow-up
Assessments are conducted at baseline (1-2 weeks before intervention) and after the 12-week intervention ends (1-2 weeks after).

What this trial measures

  • Inhibition speedAt the baseline (1-2 weeks) before intervention starts and after (1-2 weeks) the intervention ends

    Inhibition speed will be assessed by the response time (ms) during a child-friendly flanker task.

  • Inhibition accuracyAt the baseline (1-2 weeks) before intervention starts and after (1-2 weeks) the intervention ends

    Inhibition accuracy will be assessed by the response accuracy (percent) during a child-friendly flanker task.

  • Updating speedAt the baseline (1-2 weeks) before intervention starts and after (1-2 weeks) the intervention ends

    Updating speed will be assessed by the response time (ms) during a child-friendly n-back task.

  • Updating accuracyAt the baseline (1-2 weeks) before intervention starts and after (1-2 weeks) the intervention ends

    Updating accuracy will be assessed by the response accuracy (percent) during a child-friendly n-back task.

  • Shifting speedAt the baseline (1-2 weeks) before intervention starts and after (1-2 weeks) the intervention ends

    Shifting speed will be assessed by the response time (ms) during a child-friendly switching task.

  • Shifting accuracyAt the baseline (1-2 weeks) before intervention starts and after (1-2 weeks) the intervention ends

    Shifting accuracy will be assessed by the response accuracy (percent) during a child-friendly switching task.
