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.

Interventions

Type	Name	Description
BEHAVIORAL	MF-HIIT	A single bout of 20-min MF-HIIT protocol delivered through a motor-driven treadmill. The protocol will start with a 1.5-min warm-up, then a 16.5-min main exercise (6 x 90s exercise intervals separated by 5 x 90s mindful intervals), and finally a 2-min cool-down.
BEHAVIORAL	MF-only	A single bout of 20-min intervention mindfulness intervention that includes 5 x 90s mindful intervals separated by sitting rest
BEHAVIORAL	HIIT-only	A single bout of 20-min HIIT protocol delivered through a motor-driven treadmill. The protocol will start with a 1.5-min warm-up, then a 16.5-min main exercise (6 x 90s exercise intervals separated by 5 x 90s rest intervals), and finally a 2-min cool-down.
BEHAVIORAL	Sitting rest	Participants will sit in a comfortable chair, placed on the treadmill, while watching a HIIT video without mindfulness instructions for 20 minutes.
