Study Overview
Brief Summary
The goal of this randomized cross-over trial is to learn about the effect of a single bout of 20-min mindfulness-based high-intensity interval training (MF-HIIT), MF-only, and HIIT-only in relative to sitting rest on executive function (EF) in 10-12 years old children. The main question it aims to answer are:
Question 1: Whether a single bout of 20-min MF-HIIT has larger beneficial effect on EF performance than that following a 20-min session of MF-only and HIIT-only in relative to the sitting rest
Question 2: Whether a single bout of 20-min MF-HIIT has a larger beneficial effect on brain functioning, as measured by the N2 and P3 components of event-related potential (ER) during EF performance than that following a 20-min session of MF-only and HIIT-only in relative to the sitting rest
Participants will visit the laboratory on 5 separate days (> 2-day washout between days) in which they have not previously participated in structured physical activities.
Participants will complete the testing and/or receive treatments below:
Day 1:
- Kaufman Brief Intelligence Test (KBIT) to assess intelligence quotient
- Treadmill-based exercise test to measure cardiorespiratory fitness (maximum oxygen consumption)
Days 2-5
- Each day, participants will complete each of the four intervention conditions (MF-HIIT, MF-only, HIIT-only, sitting)
- Participants' heart rate and self-reported affect and rating of physical exertion will be measured
- Participants will complete a modified flanker task and a task-switching task to assess inhibitory control and cognitive flexibility
- Participants will wear an EEG cap to measure the N2 and P3 components of the event-related potential during the inhibitory control and cognitive flexibility performance
Researcher will compare the cognitive outcome measures following the MF-HIIT, MF-only, and HIIT-only conditions with the sitting condition to see if MF and HIIT has beneficial effects on children's EF.
Further, researcher will compare the cognitive outcome measures following the MF-HIIT compared with MF-only and HIIT-only conditions to see if combining MF with HIIT has greater beneficial effects on children's EF than MF and HIIT alone.

Intervention: MF-only (Behavioral)
A Single Bout Of Mindful High-Intensity Interval Training (Mindful HIIT)

Outcomes
Primary Outcomes
Inhibition speed
Time Frame: At the baseline before and about 10-min after the 20-min intervention on Day 2, Day 3, Day 4, and Day 5.
Inhibition speed will be assessed by the response time (ms) during a child-friendly flanker task.
N2-ERP
Time Frame: At the baseline before and about 10-min after the 20-min intervention on Day 2, Day 3, Day 4, and Day 5.
The N2 component of event-related brain potentials is a neuroelectric index of conflict processing. Increased amplitude of N2 reflects increased neural activation to detect and resolve conflicts.
P3-ERP
Time Frame: At the baseline before and about 10-min after the 20-min intervention on Day 2, Day 3, Day 4, and Day 5.
The P3 component of event-related brain potentials is a neuroelectric index of attention. Increased amplitude of P3 reflects greater allocation of attentional resources and the decreased latency of P3 reflects the faster information processing speed.
Inhibition accuracy
Time Frame: At the baseline before and about 10-min after the 20-min intervention on Day 2, Day 3, Day 4, and Day 5.
Inhibition accuracy will be assessed by the response accuracy (%) during a child-friendly flanker task.
Shifting speed
Time Frame: At the baseline before and about 10-min after the 20-min intervention on Day 2, Day 3, Day 4, and Day 5.
The shifting speed will be assessed by the response time (ms) during a child-friendly switching task.
Shifting accuracy
Time Frame: At the baseline before and about 10-min after the 20-min intervention on Day 2, Day 3, Day 4, and Day 5.
The shifting accuracy will be assessed by the response accuracy (%) during a child-friendly switching task.
Secondary Outcomes
- Heart Rate(Heart rate will be measured at every minute (minutes 0, 1, 2, 3, 4, ...., 18, 19, 20) during the 20-min intervention on Day 2, Day 3, Day 4, and Day 5.)
- State Mindfulness Scale for Physical Activity (SMSPA)(Immediately after completing the 20-min intervention on Day 2, Day 3, Day 4, and Day 5.)
- Rating of perceived exertion(Measure at 0 second, 90 seconds, 180 seconds, 270 seconds, 360 seconds, 450 seconds, 540 seconds, 630 seconds, 720 seconds, 810 seconds, 900 seconds, 990 seconds, 1080 seconds and 1200 seconds of the 20-min intervention on Day 2, Day 3, Day 4, and Day 5.)
