Brief Summary

The goal of this randomized controlled trial is to learn about the effect of a 12-week school-based intervention combining mindfulness with high-intensity interval training (MF-HIIT), MF-only intervention, and HIIT-only intervention in relative to sedentary activities on executive function (EF) in 8-12 years old children. The main question it aims to answer is whether a 12-week school-based MF-HIIT intervention has larger beneficial effect on EF performance than that following a 12-week school-based MF-only and HIIT-only in relative to the sedentary activities.

Multiple cohorts of participants will be recruited to participate this one-semester study, including the pretest, intervention, and posttest phases.

During the pretest phase, participants an their parents will complete the following

1. Kaufman Brief Intelligence Test (KBIT) to assess intelligence quotient

2. Fitnessgram test to assess aerobic capacity, muscle endurance, flexibility, and body mass index

3. Child and Adolescent Mindfulness Measure (CAMM) questionnaire to assess dispositional mindfulness

4. Computerized tasks to assess EF

5. Parent-reported demographic and health information

Following the pretest phase, participants will receive the 12-week classroom-based intervention, with the classroom as the intervention unit.

Following the intervention and during the posttest phase, participants will complete the fitness, measures, EF measures, and dispositional mindfulness measure again.

Researcher will compare the EFn outcome measures following the MF-HIIT, MF-only, and HIIT-only interventions with the sedentary activity intervention to see if MF and HIIT has beneficial effects on children's EF.

Further, researcher will compare the EF measures following the MF-HIIT compared with MF-only and HIIT-only interventions to see if combining MF with HIIT has greater beneficial effects on children's EF than MF and HIIT alone.

Primary Outcome Measures
NameTimeMethod
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.

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.

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.

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 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.

Secondary Outcome Measures
NameTimeMethod
Body compositionAt the baseline (1-2 weeks) before intervention starts and after (1-2 weeks) the intervention ends

body composition will be assessed by the body mass index computed as weight (kg) / (height \[m\] \* height \[m\])

Core body muscle enduranceAt the baseline (1-2 weeks) before intervention starts and after (1-2 weeks) the intervention ends

Core body muscle endurance will be assessed by the curl-ups test

Aerobic capacityAt the baseline (1-2 weeks) before intervention starts and after (1-2 weeks) the intervention ends

Aerobic capacity will be assessed by the Progressive Aerobic Cardiovascular Endurance Run (PACER) test

Dispositional mindfulnessAt the baseline (1-2 weeks) before intervention starts and after (1-2 weeks) the intervention ends

Dispositional mindfulness will be assessed by the Child and Adolescent Mindfulness Measure questionnaire (CAMM). The questionnaire has 10 items and requires the respondents to rating each item using a 5-point likert scale from 0 (Never True) to 4 (Always True). Higher summed scores indicate higher levels of mindfulness

FlexibilityAt the baseline (1-2 weeks) before intervention starts and after (1-2 weeks) the intervention ends

Flexibility will be assessed by the back-saver sit and reach test

Upper body muscle enduranceAt the baseline (1-2 weeks) before intervention starts and after (1-2 weeks) the intervention ends

Upper body muscle endurance will be assessed by the push-ups test
